                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2017), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not accidentally dropped due to a printing or computer error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Sec. 1.2  Business to be transacted in writing.

    All business with the Patent and Trademark Office should be 
transacted in writing. The personal attendance of applicants or their 
attorneys or agents at the Patent and Trademark Office is unnecessary. 
The action of the Patent and Trademark Office will be based exclusively 
on the written record in the Office. No attention will be paid to any 
alleged oral promise, stipulation, or understanding in relation to which 
there is disagreement or doubt.



Sec. 1.3  Business to be conducted with decorum and courtesy.

    Applicants and their attorneys or agents are required to conduct 
their business with the United States Patent and Trademark Office with 
decorum and courtesy. Papers presented in violation of this requirement 
will be submitted to the Director and will not be entered. A notice of 
the non-entry of the paper will be provided. Complaints against 
examiners and other employees must be made in correspondence separate 
from other papers.

[68 FR 38624, June 30, 2003]



Sec. 1.4  Nature of correspondence and signature requirements.

    (a) Correspondence with the Patent and Trademark Office comprises:
    (1) Correspondence relating to services and facilities of the 
Office, such as general inquiries, requests for publications supplied by 
the Office, orders for printed copies of patents, orders for copies of 
records, transmission of assignments for recording, and the like, and
    (2) Correspondence in and relating to a particular application or 
other proceeding in the Office. See particularly the rules relating to 
the filing, processing, or other proceedings of national applications in 
subpart B of this part; of international applications in subpart C of 
this part; of ex parte reexaminations of patents in subpart D of this 
part; of supplemental examination of patents in subpart E of this part; 
of extension of patent term in subpart F of this part; of inter partes 
reexaminations of patents in subpart H of this part; of international 
design applications in subpart I of this part; and of the Patent Trial 
and Appeal Board in parts 41 and 42 of this chapter.
    (b) Since each file must be complete in itself, a separate copy of 
every paper to be filed in a patent application, patent file, or other 
proceeding must be furnished for each file to which the paper pertains, 
even though the contents of the papers filed in two or more files may be 
identical. The filing of duplicate copies of correspondence in the file 
of an application, patent, or other proceeding should be avoided, except 
in situations in which the Office requires the filing of duplicate 
copies. The Office may dispose of duplicate copies of correspondence in 
the file of an application, patent, or other proceeding.

[[Page 14]]

    (c) Since different matters may be considered by different branches 
or sections of the Office, each distinct subject, inquiry, or order must 
be contained in a separate paper to avoid confusion and delay in 
answering papers dealing with different subjects. Subjects provided for 
on a single Office or World Intellectual Property Organization form may 
be contained in a single paper.
    (d)(1) Handwritten signature. Each piece of correspondence, except 
as provided in paragraphs (d)(2), (d)(3), (d)(4), (e), and (f) of this 
section, filed in an application, patent file, or other proceeding in 
the Office which requires a person's signature, must:
    (i) Be an original, that is, have an original handwritten signature 
personally signed, in permanent dark ink or its equivalent, by that 
person; or
    (ii) Be a direct or indirect copy, such as a photocopy or facsimile 
transmission (Sec. 1.6(d)), of an original. In the event that a copy of 
the original is filed, the original should be retained as evidence of 
authenticity. If a question of authenticity arises, the Office may 
require submission of the original.
    (2) S-signature. An S-signature is a signature inserted between 
forward slash marks, but not a handwritten signature as defined by 
paragraph (d)(1) of this section. An S-signature includes any signature 
made by electronic or mechanical means, and any other mode of making or 
applying a signature other than a handwritten signature as provided for 
in paragraph (d)(1) of this section. Correspondence being filed in the 
Office in paper, by facsimile transmission as provided in Sec. 1.6(d), 
or via the Office electronic filing system as an attachment as provided 
in Sec. 1.6(a)(4), for a patent application, patent, or a reexamination 
or supplemental examination proceeding may be S-signature signed instead 
of being personally signed (i.e., with a handwritten signature) as 
provided for in paragraph (d)(1) of this section. The requirements for 
an S-signature under this paragraph (d)(2) of this section are as 
follows.
    (i) The S-signature must consist only of letters, or Arabic 
numerals, or both, with appropriate spaces and commas, periods, 
apostrophes, or hyphens for punctuation, and the person signing the 
correspondence must insert his or her own S-signature with a first 
single forward slash mark before, and a second single forward slash mark 
after, the S-signature (e.g.,/Dr. James T. Jones, Jr./); and
    (ii) A patent practitioner (Sec. 1.32(a)(1)), signing pursuant to 
Secs. 1.33(b)(1) or 1.33(b)(2), must supply his/her registration number 
either as part of the S-signature, or immediately below or adjacent to 
the S-signature. The number (#) character may be used only as part of 
the S-signature when appearing before a practitioner's registration 
number; otherwise the number character may not be used in an S-
signature.
    (iii) The signer's name must be:
    (A) Presented in printed or typed form preferably immediately below 
or adjacent the S-signature, and
    (B) Reasonably specific enough so that the identity of the signer 
can be readily recognized.
    (3) Electronically submitted correspondence. Correspondence 
permitted via the Office electronic filing system may be signed by a 
graphic representation of a handwritten signature as provided for in 
paragraph (d)(1) of this section or a graphic representation of an S-
signature as provided for in paragraph (d)(2) of this section when it is 
submitted via the Office electronic filing system.
    (4) Certifications--(i) Certification as to the paper presented. The 
presentation to the Office (whether by signing, filing, submitting, or 
later advocating) of any paper by a party, whether a practitioner or 
non-practitioner, constitutes a certification under Sec. 11.18(b) of 
this subchapter. Violations of Sec. 11.18(b)(2) of this subchapter by a 
party, whether a practitioner or non-practitioner, may result in the 
imposition of sanctions under Sec. 11.18(c) of this subchapter. Any 
practitioner violating Sec. 11.18(b) of this subchapter may also be 
subject to disciplinary action. See Sec. 11.18(d) of this subchapter.
    (ii) Certification as to the signature. The person inserting a 
signature under paragraph (d)(2) or (d)(3) of this section in a document 
submitted to the Office certifies that the inserted signature appearing 
in the document is his or her own signature. A person submitting a 
document signed by another under paragraph (d)(2) or (d)(3) of this 
section

[[Page 15]]

is obligated to have a reasonable basis to believe that the person whose 
signature is present on the document was actually inserted by that 
person, and should retain evidence of authenticity of the signature. 
Violations of the certification as to the signature of another or a 
person's own signature as set forth in this paragraph may result in the 
imposition of sanctions under Sec. 11.18(c) and (d) of this chapter.
    (5) Forms. The Office provides forms for the public to use in 
certain situations to assist in the filing of correspondence for a 
certain purpose and to meet certain requirements for patent applications 
and proceedings. Use of the forms for purposes for which they were not 
designed is prohibited. No changes to certification statements on the 
Office forms (e.g., oath or declaration forms, terminal disclaimer 
forms, petition forms, and nonpublication request forms) may be made. 
The existing text of a form, other than a certification statement, may 
be modified, deleted, or added to, if all text identifying the form as 
an Office form is removed. The presentation to the Office (whether by 
signing, filing, submitting, or later advocating) of any Office form 
with text identifying the form as an Office form by a party, whether a 
practitioner or non-practitioner, constitutes a certification under 
Sec. 11.18(b) of this chapter that the existing text and any 
certification statements on the form have not been altered other than 
permitted by EFS-Web customization.
    (e) The following correspondence must be submitted with an original 
handwritten signature personally signed in permanent dark ink or its 
equivalent:
    (1) Correspondence requiring a person's signature and relating to 
registration to practice before the Patent and Trademark Office in 
patent cases, enrollment and disciplinary investigations, or 
disciplinary proceedings; and
    (2) Payments by credit cards where the payment is not being made via 
the Office's electronic filing systems.
    (f) When a document that is required by statute to be certified must 
be filed, a copy, including a photocopy or facsimile transmission, of 
the certification is not acceptable.
    (g) An applicant who has not made of record a registered attorney or 
agent may be required to state whether assistance was received in the 
preparation or prosecution of the patent application, for which any 
compensation or consideration was given or charged, and if so, to 
disclose the name or names of the person or persons providing such 
assistance. Assistance includes the preparation for the applicant of the 
specification and amendments or other papers to be filed in the Patent 
and Trademark Office, as well as other assistance in such matters, but 
does not include merely making drawings by draftsmen or stenographic 
services in typing papers.
    (h) Ratification/confirmation/evidence of authenticity: The Office 
may require ratification, confirmation (which includes submission of a 
duplicate document but with a proper signature), or evidence of 
authenticity of a signature, such as when the Office has reasonable 
doubt as to the authenticity (veracity) of the signature, e.g., where 
there are variations of a signature, or where the signature and the 
typed or printed name, do not clearly identify the person signing.

Sec. 1.5  Identification of patent, patent application, or 
patent-related proceeding.

    (a) No correspondence relating to an application should be filed 
prior to receipt of the assigned application number (i.e., U.S. 
application number, international application number, or international 
registration number as appropriate). When correspondence directed to the 
Patent and Trademark Office concerns a previously filed application for 
a patent, it must identify on the top page in a conspicuous location, 
the application number (consisting of the series code and the serial 
number; e.g., 07/123,456), or the serial number and filing date assigned 
to that application by the Patent and Trademark

[[Page 16]]

Office, or the international application number of the international 
application, or the international registration number of an 
international design application. Any correspondence not containing such 
identification will be returned to the sender where a return address is 
available. The returned correspondence will be accompanied with a cover 
letter, which will indicate to the sender that if the returned 
correspondence is resubmitted to the Patent and Trademark Office within 
two weeks of the mail date on the cover letter, the original date of 
receipt of the correspondence will be considered by the Patent and 
Trademark Office as the date of receipt of the correspondence. 
Applicants may use either the Certificate of Mailing or Transmission 
procedure under Sec. 1.8 or the Priority Mail Express 
procedure under Sec. 1.10 for resubmissions of returned correspondence 
if they desire to have the benefit of the date of deposit in the United 
States Postal Service. If the returned correspondence is not resubmitted 
within the two-week period, the date of receipt of the resubmission will 
be considered to be the date of receipt of the correspondence. The two-
week period to resubmit the returned correspondence will not be 
extended. In addition to the application number, all correspondence 
directed to the Patent and Trademark Office concerning applications for 
patent should also state the name of the first listed inventor, the 
title of the invention, the date of filing the same, and if known, the 
group art unit or other unit within the Patent and Trademark Office 
responsible for considering the correspondence and the name of the 
examiner or other person to which it has been assigned.
    (b) When the letter concerns a patent other than for purposes of 
paying a maintenance fee, it should state the number and date of issue 
of the patent, the name of the patentee, and the title of the invention. 
For letters concerning payment of a maintenance fee in a patent, see the 
provisions of Sec. 1.366(c).
    (c) Correspondence relating to a trial proceeding before the Patent 
Trial and Appeal Board (part 42 of this title) are governed by Sec. 42.6 
of this title.
    (d) A letter relating to a reexamination or supplemental examination 
proceeding should identify it as such by the number of the patent 
undergoing reexamination or supplemental examination, the request 
control number assigned to such proceeding, and, if known, the group art 
unit and name of the examiner to which it been assigned.
    (e) [Reserved]
    (f) When a paper concerns a provisional application, it should 
identify the application as such and include the application number.

Sec. 1.10  Filing of correspondence by Priority Mail Express.

    (a)(1) Any correspondence received by the U.S. Patent and Trademark 
Office (USPTO) that was delivered by the Priority Mail 
Express Post Office to Addressee service of the United 
States Postal Service (USPS) will be considered filed with the USPTO on 
the date of deposit with the USPS.
    (2) The date of deposit with USPS is shown by the ``date accepted'' 
on the Priority Mail Express label or other official USPS 
notation. If the USPS deposit date cannot be determined, the 
correspondence will be accorded the USPTO receipt date as the filing 
date. See Sec. 1.6(a).
    (b) Correspondence should be deposited directly with an employee of 
the USPS to ensure that the person depositing the correspondence 
receives a legible copy of the Priority Mail Express mailing 
label with the ``date accepted'' clearly marked. Persons dealing 
indirectly with the employees of the USPS (such as by deposit in a 
Priority Mail Express drop box) do so at the risk of not 
receiving a copy of the Priority Mail Express mailing label 
with the desired ``date accepted'' clearly marked. The paper(s) or 
fee(s) that constitute the correspondence should also include the 
Priority Mail Express mailing label number thereon. See 
paragraphs (c), (d) and (e) of this section.
    (c) Any person filing correspondence under this section that was 
received by the Office and delivered by the Priority Mail

``date accepted'' on the Priority Mail Express mailing label 
or other official USPS notation, may petition the Director to accord the 
correspondence a filing date as of the ``date accepted'' on the Priority 
Mail Express mailing label or other official USPS notation, 
provided that:
    (1) The petition is filed promptly after the person becomes aware 
that the Office has accorded, or will accord, a filing date other than 
the USPS deposit date;
    (2) The number of the Priority Mail Express mailing 
label was placed on the paper(s) or fee(s) that constitute the 
correspondence prior to the original mailing by Priority Mail 
Express; and
    (3) The petition includes a true copy of the Priority Mail 
Express mailing label showing the ``date accepted,'' and of 
any other official notation by the USPS relied upon to show the date of 
deposit.
    (d) Any person filing correspondence under this section that was 
received by the Office and delivered by the Priority Mail 
Express Post Office to Addressee service of the USPS, who 
can show that the ``date accepted'' on the Priority Mail 
Express mailing label or other official notation entered by 
the USPS was incorrectly entered or omitted by the USPS, may petition 
the Director to accord the correspondence a filing date as of the date 
the correspondence is shown to have been deposited with the USPS, 
provided that:
    (1) The petition is filed promptly after the person becomes aware 
that the Office has accorded, or will accord, a filing date based upon 
an incorrect entry by the USPS;
    (2) The number of the Priority Mail Express mailing 
label was placed on the paper(s) or fee(s) that constitute the 
correspondence prior to the original mailing by Priority Mail 
Express; and

satisfaction of the Director, that the requested filing date was the 
date the correspondence was deposited in the Priority Mail 
Express Post Office to Addressee service prior to the last 
scheduled pickup for that day. Any showing pursuant to

[[Page 22]]

this paragraph must be corroborated by evidence from the USPS or that 
came into being after deposit and within one business day of the deposit 
of the correspondence in the Priority Mail Express Post 
Office to Addressee service of the USPS.
    (e) Any person mailing correspondence addressed as set out in 
Sec. 1.1(a) to the Office with sufficient postage utilizing the Priority 
Mail Express Post Office to Addressee service of the USPS 
but not received by the Office, may petition the Director to consider 
such correspondence filed in the Office on the USPS deposit date, 
provided that:
    (1) The petition is filed promptly after the person becomes aware 
that the Office has no evidence of receipt of the correspondence;
    (2) The number of the Priority Mail Express mailing 
label was placed on the paper(s) or fee(s) that constitute the 
correspondence prior to the original mailing by Priority Mail 
Express;
    (3) The petition includes a copy of the originally deposited 
paper(s) or fee(s) that constitute the correspondence showing the number 
of the Priority Mail Express mailing label thereon, a copy 
of any returned postcard receipt, a copy of the Priority Mail 
Express mailing label showing the ``date accepted,'' a copy 
of any other official notation by the USPS relied upon to show the date 
of deposit, and, if the requested filing date is a date other than the 
``date accepted'' on the Priority Mail Express mailing label 
or other official notation entered by the USPS, a showing pursuant to 
paragraph (d)(3) of this section that the requested filing date was the 
date the correspondence was deposited in the Priority Mail 
Express Post Office to Addressee service prior to the last 
scheduled pickup for that day; and
    (4) The petition includes a statement which establishes, to the 
satisfaction of the Director, the original deposit of the correspondence

Express mailing label, returned postcard receipt, and 
official notation entered by the USPS.

Sec. 1.1(a) to the Office with sufficient postage utilizing the Priority 
Mail Express Post Office to Addressee service of the USPS, 
but has the correspondence returned by the USPS due to an interruption 
or emergency in Priority Mail Express service, may petition 
the Director to consider such correspondence as filed on a particular 
date in the Office, provided that:
    (1) The petition is filed promptly after the person becomes aware of

    (2) The number of the Priority Mail Express mailing 
label was placed on the paper(s) or fee(s) that constitute the 
correspondence prior to the original mailing by Priority Mail 
Express;
    (3) The petition includes the original correspondence or a copy of 
the original correspondence showing the number of the Priority Mail 
Express mailing label thereon and a copy of the Priority

satisfaction of the Director, the original deposit of the correspondence 
and that the correspondence or copy of the correspondence is the 
original correspondence or a true copy of the correspondence originally 
deposited with the USPS on the requested filing date. The Office may 
require additional evidence to determine if the correspondence was 
returned by the USPS due to an interruption or emergency in Priority 
Mail Express service.
    (h) Any person who attempts to mail correspondence addressed as set 
out in Sec. 1.1(a) to the Office with sufficient postage utilizing the 
Priority Mail Express Post Office to Addressee service of 
the USPS, but has the correspondence refused by an employee of the USPS 
due to an interruption or emergency in Priority Mail Express

the original correspondence showing the number of the Priority Mail 
Express mailing label thereon; and
    (4) The petition includes a statement by the person who originally 
attempted to deposit the correspondence with the USPS which establishes, 
to the satisfaction of the Director, the original attempt to deposit the 
correspondence and that the correspondence or copy of the correspondence 
is the original correspondence or a true copy of the correspondence 
originally attempted to be deposited with the USPS on the requested 
filing date. The Office may require additional evidence to determine if 
the correspondence was refused by an employee of the USPS due to an 
interruption or emergency in Priority Mail Express service.
    (i) Any person attempting to file correspondence under this section 
that was unable to be deposited with the USPS due to an interruption or

designated by the Director, may petition the Director to consider such 
correspondence as filed on a particular date in the Office, provided

Sec. 1.14  Patent applications preserved in confidence.

    (a) Confidentiality of patent application information. Patent 
applications that have not been published under 35 U.S.C. 122(b) are 
generally preserved in confidence pursuant to 35 U.S.C. 122(a). 
Information concerning the filing, pendency, or subject matter of an 
application for patent, including status information, and access to the 
application, will only be given to the public as set forth in Sec. 1.11 
or in this section.
    (1) Records associated with patent applications (see paragraph (g) 
of this section for international applications and paragraph (j) of this 
section for international design applications) may be available in the 
following situations:
    (i) Patented applications and statutory invention registrations. The 
file of an application that has issued as a patent or published as a 
statutory invention registration is available to the public as set forth 
in Sec. 1.11(a). A copy of the patent application-as-filed, the file 
contents of the application, or a specific document in the file of such 
an application may be provided upon request and payment of the 
appropriate fee set forth in Sec. 1.19(b).
    (ii) Published abandoned applications. The file of an abandoned 
published application is available to the public as set forth in 
Sec. 1.11(a). A copy of the application-as-filed, the file contents of 
the published application, or a specific document in the file of the 
published application may be provided to any person upon request and 
payment of the appropriate fee set forth in Sec. 1.19(b).
    (iii) Published pending applications. A copy of the application-as-
filed, the file contents of the application, or a specific document in 
the file of a pending published application may be provided to any 
person upon request and payment of the appropriate fee set forth in 
Sec. 1.19(b). If a redacted copy of the application was used for the 
patent application publication, the copy of the specification, drawings, 
and papers may be limited to a redacted copy. The Office will not 
provide access to the paper file of a pending application that has been 
published, except as provided in paragraph (c) or (i) of this section.
    (iv) Unpublished abandoned applications (including provisional 
applications) that are identified or relied upon. The file contents of 
an unpublished, abandoned application may be made available to the 
public if the application is identified in a U.S. patent, a statutory 
invention registration, a U.S. patent application publication, an 
international publication of an international application under PCT 
Article 21(2), or a publication of an international registration under 
Hague Agreement Article 10(3) of an international design application 
designating the United States. An application is considered to have been 
identified in a document, such as a patent, when the application number 
or serial number and filing date, first named inventor, title, and 
filing date or other application specific information are provided in 
the text of the patent, but not when the same identification is made in 
a paper in the file contents of the patent and is not included in the 
printed patent. Also, the file contents may be made available to the 
public, upon a written request, if benefit of the abandoned application 
is claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in an 
application that has issued as a U.S. patent, or has published as a 
statutory invention registration, a U.S. patent application publication, 
an international publication of an international application under PCT 
Article 21(2), or a publication of an international registration under 
Hague Agreement Article 10(3). A copy of the application-as-filed, the 
file

[[Page 26]]

contents of the application, or a specific document in the file of the 
application may be provided to any person upon written request and 
payment of the appropriate fee (Sec. 1.19(b)).
    (v) Unpublished pending applications (including provisional 
applications) whose benefit is claimed. A copy of the file contents of 
an unpublished pending application may be provided to any person, upon 
written request and payment of the appropriate fee (Sec. 1.19(b)), if 
the benefit of the application is claimed under 35 U.S.C. 119(e), 120, 
121, 365(c), or 386(c) in an application that has issued as a U.S. 
patent, or in an application that has published as a statutory invention 
registration, a U.S. patent application publication, an international 
publication of an international application under PCT Article 21(2), or 
a publication of an international registration under Hague Agreement 
Article 10(3). A copy of the application-as-filed or a specific document 
in the file of the pending application may also be provided to any 
person upon written request and payment of the appropriate fee 
(Sec. 1.19(b)). The Office will not provide access to the paper file of 
a pending application, except as provided in paragraph (c) or (i) of 
this section.
    (vi) Unpublished pending applications (including provisional 
applications) that are incorporated by reference or otherwise 
identified. A copy of the application as originally filed of an 
unpublished pending application may be provided to any person, upon 
written request and payment of the appropriate fee (Sec. 1.19(b)), if 
the application is incorporated by reference or otherwise identified in 
a U.S. patent, a statutory invention registration, a U.S. patent 
application publication, an international publication of an 
international application under PCT Article 21(2), or a publication of 
an international registration under Hague Agreement Article 10(3) of an 
international design application designating the United States. The 
Office will not provide access to the paper file of a pending 
application, except as provided in paragraph (c) or (i) of this section.
    (vii) When a petition for access or a power to inspect is required. 
Applications that were not published or patented, that are not the 
subject of a benefit claim under 35 U.S.C. 119(e), 120, 121, 365(c), or 
386(c) in an application that has issued as a U.S. patent, an 
application that has published as a statutory invention registration, a 
U.S. patent application publication, an international publication of an 
international application under PCT Article 21(2), or a publication of 
an international registration under Hague Agreement Article 10(3), or 
are not identified in a U.S. patent, a statutory invention registration, 
a U.S. patent application publication, an international publication of 
an international application under PCT Article 21(2), or a publication 
of an international registration under Hague Agreement Article 10(3) of 
an international design application designating the United States, are 
not available to the public. If an application is identified in the file 
contents of another application, but not the published patent 
application or patent itself, a granted petition for access (see 
paragraph (i)) or a power to inspect (see paragraph (c) of this section) 
is necessary to obtain the application, or a copy of the application.
    (2) Information concerning a patent application may be communicated 
to the public if the patent application is identified in a published 
patent document or in an application as set forth in paragraphs 
(a)(1)(i) through (a)(1)(vi) of this section. The information that may 
be communicated to the public (i.e., status information) includes:
    (i) Whether the application is pending, abandoned, or patented;
    (ii) Whether the application has been published under 35 U.S.C. 
122(b);
    (iii) The application ``numerical identifier'' which may be:
    (A) The eight-digit application number (the two-digit series code 
plus the six-digit serial number); or
    (B) The six-digit serial number plus any one of the filing date of 
the national application, the international filing date, or date of 
entry into the national stage; and
    (iv) Whether another application claims the benefit of the 
application (i.e., whether there are any applications that claim the 
benefit of the filing date under 35 U.S.C. 119(e), 120, 121, 365, or 386 
of the application), and if there are any such applications, the

[[Page 27]]

numerical identifier of the application, the specified relationship 
between the applications (e.g., continuation), whether the application 
is pending, abandoned or patented, and whether the application has been 
published under 35 U.S.C. 122(b).
    (b) Electronic access to an application. Where a copy of the 
application file or access to the application may be made available 
pursuant to this section, the Office may at its discretion provide 
access to only an electronic copy of the specification, drawings, and 
file contents of the application.
    (c) Power to inspect a pending or abandoned application. Access to 
an application may be provided to any person if the application file is 
available, and the application contains written authority (e.g., a power 
to inspect) granting access to such person. The written authority must 
be signed by:
    (1) The applicant;
    (2) A patent practitioner of record;
    (3) The assignee or an assignee of an undivided part interest;
    (4) The inventor or a joint inventor; or
    (5) A registered attorney or agent named in the papers accompanying 
the application papers filed under Sec. 1.53 or the national stage 
documents filed under Sec. 1.495, if a power of attorney has not been 
appointed under Sec. 1.32.
    (d) Applications reported to Department of Energy. Applications for 
patents which appear to disclose, purport to disclose or do disclose 
inventions or discoveries relating to atomic energy are reported to the 
Department of Energy, which Department will be given access to the 
applications. Such reporting does not constitute a determination that 
the subject matter of each application so reported is in fact useful or 
is an invention or discovery, or that such application in fact discloses 
subject matter in categories specified by 42 U.S.C. 2181(c) and (d).
    (e) Decisions by the Director. Any decision by the Director that 
would not otherwise be open to public inspection may be published or 
made available for public inspection if:
    (1) The Director believes the decision involves an interpretation of 
patent laws or regulations that would be of precedential value; and
    (2) The applicant is given notice and an opportunity to object in 
writing within two months on the ground that the decision discloses a 
trade secret or other confidential information. Any objection must 
identify the deletions in the text of the decision considered necessary 
to protect the information, or explain why the entire decision must be 
withheld from the public to protect such information. An applicant or 
party will be given time, not less than twenty days, to request 
reconsideration and seek court review before any portions of a decision 
are made public under this paragraph over his or her objection.
    (f) Notice to inventor of the filing of an application. The Office 
may publish notice in the Official Gazette as to the filing of an 
application on behalf of an inventor by a person who otherwise shows 
sufficient proprietary interest in the matter.
    (g) International applications. (1) Copies of international 
application files for international applications which designate the 
U.S. and which have been published in accordance with PCT Article 21(2),

Sec. 1.22  Fees payable in advance.

    (a) Patent fees and charges payable to the United States Patent and 
Trademark Office are required to be paid in advance; that is, at the 
time of requesting any action by the Office for which a fee or charge is 
payable, with the exception that under Sec. 1.53 applications for patent 
may be assigned a filing date without payment of the basic filing fee.
    (b) All fees paid to the United States Patent and Trademark Office 
must be itemized in each individual application, patent, or other 
proceeding in such a manner that it is clear for which purpose the fees 
are paid. The Office may return fees that are not itemized as required 
by this paragraph. The provisions of Sec. 1.5(a) do not apply to the 
resubmission of fees returned pursuant to this paragraph.

[68 FR 48288, Aug. 13, 2003]



Sec. 1.23  Methods of payment.

    (a) All payments of money required for United States Patent and 
Trademark Office fees, including fees for the processing of 
international applications (Sec. 1.445), shall be made in U.S. dollars 
and in the form of a cashier's or certified check, Treasury note, 
national bank notes, or United States Postal Service money order. If 
sent in any other form, the Office may delay or cancel the credit until 
collection is made. Checks and money orders must be made payable to the 
Director of the United States Patent and Trademark Office. (Checks made 
payable to the Commissioner of Patents and Trademarks will continue to 
be accepted.) Payments from foreign countries must be payable and 
immediately negotiable in the United States for the full amount of the 
fee required. Money sent to the Office by mail will be at the risk of 
the sender, and letters containing money should be registered with the 
United States Postal Service.
    (b) Payments of money required for United States Patent and 
Trademark Office fees may also be made by credit card, except for 
replenishing a deposit account. Payment of a fee by credit card must 
specify the amount to be charged to the credit card and such other 
information as is necessary to process the charge, and is subject to 
collection of the fee. The Office will not accept a general 
authorization to charge fees to a credit card. If credit card 
information is provided on a form or document other than a form provided 
by the Office for the payment of fees by credit card, the Office will 
not be liable if the credit card number becomes public knowledge.

[[Page 39]]

    (c) A fee transmittal letter may be signed by a juristic applicant 
or patent owner.

[65 FR 33455, May 24, 2000, as amended at 69 FR 43752, July 22, 2004; 78 
FR 62395, Oct. 21, 2013]



Sec. 1.24  [Reserved]



Sec. 1.25  Deposit accounts.

    (a) For the convenience of attorneys, and the general public in 
paying any fees due, in ordering services offered by the Office, copies 
of records, etc., deposit accounts may be established in the Patent and 
Trademark Office upon payment of the fee for establishing a deposit 
account (Sec. 1.21(b)(1)). A minimum deposit of $1,000 is required for 
paying any fees due or in ordering any services offered by the Office. 
However, a minimum deposit of $300 may be paid to establish a restricted 
subscription deposit account used exclusively for subscription order of 
patent copies as issued. At the end of each month, a deposit account 
statement will be rendered. A remittance must be made promptly upon 
receipt of the statement to cover the value of items or services charged 
to the account and thus restore the account to its established normal 
deposit. An amount sufficient to cover all fees, services, copies, etc., 
requested must always be on deposit. Charges to accounts with 
insufficient funds will not be accepted. A service charge 
(Sec. 1.21(b)(2)) will be assessed for each month that the balance at 
the end of the month is below $1,000. For restricted subscription 
deposit accounts, a service charge (Sec. 1.21(b)(3)) will be assessed 
for each month that the balance at the end of the month is below $300.
    (b) Filing, issue, appeal, international-type search report, 
international application processing, international design application 
fees, petition, and post-issuance fees may be charged against these 
accounts if sufficient funds are on deposit to cover such fees. A 
general authorization to charge all fees, or only certain fees, set 
forth in Secs. 1.16 through 1.18 to a deposit account containing 
sufficient funds may be filed in an individual application, either for 
the entire pendency of the application or with a particular paper filed. 
A general authorization to charge fees in an international design 
application set forth in Sec. 1.1031 will only be effective for the 
transmittal fee (Sec. 1.1031(a)). An authorization to charge fees under 
Sec. 1.16 in an international application entering the national stage 
under 35 U.S.C. 371 will be treated as an authorization to charge fees 
under Sec. 1.492. An authorization to charge fees set forth in Sec. 1.18 
to a deposit account is subject to the provisions of Sec. 1.311(b). An 
authorization to charge to a deposit account the fee for a request for 
reexamination pursuant to Sec. 1.510 or 1.913 and any other fees 
required in a reexamination proceeding in a patent may also be filed 
with the request for reexamination, and an authorization to charge to a 
deposit account the fee for a request for supplemental examination 
pursuant to Sec. 1.610 and any other fees required in a supplemental 
examination proceeding in a patent may also be filed with the request 
for supplemental examination. An authorization to charge a fee to a 
deposit account will not be considered payment of the fee on the date 
the authorization to charge the fee is effective unless sufficient funds 
are present in the account to cover the fee.
    (c) A deposit account holder may replenish the deposit account by 
submitting a payment to the United States Patent and Trademark Office. A 
payment to replenish a deposit account must be submitted by one of the 
methods set forth in paragraphs (c)(1), (c)(2), (c)(3), or (c)(4) of 
this section.
    (1) A payment to replenish a deposit account may be submitted by 
electronic funds transfer through the Federal Reserve Fedwire System, 
which requires that the following information be provided to the deposit 
account holder's bank or financial institution:
    (i) Name of the Bank, which is Treas NYC (Treasury New York City);
    (ii) Bank Routing Code, which is 021030004;
    (iii) United States Patent and Trademark Office account number with 
the Department of the Treasury, which is 13100001; and
    (iv) The deposit account holder's company name and deposit account 
number.

[[Page 40]]

    (2) A payment to replenish a deposit account may be submitted by 
electronic funds transfer over the Office's Internet Web site 
(www.uspto.gov).
    (3) A payment to replenish a deposit account may be addressed to: 
Director of the United States Patent and Trademark Office, Attn: Deposit 
Accounts, 2051 Jamieson Avenue, Suite 300, Alexandria, Virginia 22314.

Sec. 1.26  Refunds.

    (a) The Director may refund any fee paid by mistake or in excess of 
that required. A change of purpose after the payment of a fee, such as 
when a party desires to withdraw a patent filing for which the fee was 
paid, including an application, an appeal, or a request for an oral 
hearing, will not entitle a party to a refund of such fee. The Office 
will not refund amounts of twenty-five dollars or less unless a refund 
is specifically requested, and will not notify the payor of such 
amounts. If a party paying a fee or requesting a refund does not provide 
the banking information necessary for making refunds by electronic funds 
transfer (31 U.S.C. 3332 and 31 CFR part 208), or instruct the Office 
that refunds are to be credited to a deposit account, the Director may 
require such information, or use the banking information on the payment 
instrument to make a refund. Any refund of a fee paid by credit card 
will be by a credit to the credit card account to which the fee was 
charged.
    (b) Any request for refund must be filed within two years from the 
date the fee was paid, except as otherwise provided in this paragraph or 
in Sec. 1.28(a). If the Office charges a deposit account by an amount 
other than an amount specifically indicated in an authorization 
(Sec. 1.25(b)), any request for refund based upon such charge must be 
filed within two years from the date of the deposit account statement 
indicating such charge, and include a copy of that deposit account 
statement. The time periods set forth in this paragraph are not 
extendable.
    (c) If the Director decides not to institute a reexamination 
proceeding in response to a request for reexamination or supplemental 
examination, fees paid with the request for reexamination or 
supplemental examination will be refunded or returned in accordance with 
paragraphs (c)(1) through (c)(3) of this section. The reexamination 
requester or the patent owner who requested a supplemental examination 
proceeding, as appropriate, should indicate the form in which any refund 
should be made (e.g., by check, electronic funds transfer, credit to a 
deposit account). Generally, refunds will be issued in the form that the 
original payment was provided.
    (1) For an ex parte reexamination request, the ex parte 
reexamination filing fee paid by the reexamination requester, less the 
fee set forth in Sec. 1.20(c)(7), will be refunded to the requester if 
the Director decides not to institute an ex parte reexamination 
proceeding.
    (2) For an inter partes reexamination request, a refund of $7,970 
will be made to the reexamination requester if the Director decides not 
to institute an inter partes reexamination proceeding.
    (3) For a supplemental examination request, the fee for 
reexamination ordered as a result of supplemental examination, as set 
forth in Sec. 1.20(k)(2), will be returned to the patent owner who 
requested the supplemental examination proceeding if the Director 
decides not to institute a reexamination proceeding.

Sec. 1.27  Definition of small entities and establishing status as
a small entity to permit payment of small entity fees; when a 
determination of entitlement to small entity status and notification
of loss of entitlement to small entity status are required; fraud on
the Office.

    (a) Definition of small entities. A small entity as used in this 
chapter means any party (person, small business concern, or nonprofit 
organization) under paragraphs (a)(1) through (a)(3) of this section.
    (1) Person. A person, as used in paragraph (c) of this section, 
means any inventor or other individual (e.g., an individual to whom an 
inventor has transferred some rights in the invention) who has not 
assigned, granted, conveyed, or licensed, and is under no obligation 
under contract or law to assign, grant, convey, or license, any rights 
in the invention. An inventor or other individual who has transferred 
some rights in the invention to one or more parties, or is under an 
obligation to transfer some rights in the invention to one or more 
parties, can also qualify for small entity status if all the parties who 
have had rights in the invention transferred to them also qualify for 
small entity status either as a person, small business concern, or 
nonprofit organization under this section.
    (2) Small business concern. A small business concern, as used in 
paragraph (c) of this section, means any business concern that:
    (i) Has not assigned, granted, conveyed, or licensed, and is under 
no obligation under contract or law to assign, grant, convey, or 
license, any rights in the invention to any person, concern, or 
organization which would not qualify for small entity status as a 
person, small business concern, or nonprofit organization; and
    (ii) Meets the size standards set forth in 13 CFR 121.801 through 
121.805 to be eligible for reduced patent fees. Questions related to 
standards for a small business concern may be directed to: Small 
Business Administration, Size Standards Staff, 409 Third Street, SW., 
Washington, DC 20416.
    (3) Nonprofit Organization. A nonprofit organization, as used in 
paragraph (c) of this section, means any nonprofit organization that:
    (i) Has not assigned, granted, conveyed, or licensed, and is under 
no obligation under contract or law to assign, grant, convey, or 
license, any rights in the invention to any person, concern, or 
organization which would not qualify as a person, small business 
concern, or a nonprofit organization; and
    (ii) Is either:
    (A) A university or other institution of higher education located in 
any country;
    (B) An organization of the type described in section 501(c)(3) of 
the Internal Revenue Code of 1986 (26 U.S.C. 501(c)(3)) and exempt from 
taxation under section 501(a) of the Internal Revenue Code (26 U.S.C. 
501(a));
    (C) Any nonprofit scientific or educational organization qualified 
under a nonprofit organization statute of a state of this country (35 
U.S.C. 201(i)); or
    (D) Any nonprofit organization located in a foreign country which 
would qualify as a nonprofit organization under paragraphs (a)(3)(ii)(B) 
of this section or (a)(3)(ii)(C) of this section if it were located in 
this country.
    (4) License to a Federal agency. (i) For persons under paragraph 
(a)(1) of this section, a license to the Government resulting from a 
rights determination under Executive Order 10096 does not constitute a 
license so as to prohibit claiming small entity status.
    (ii) For small business concerns and nonprofit organizations under 
paragraphs (a)(2) and (a)(3) of this section, a license to a Federal 
agency resulting from a funding agreement with that agency pursuant to 
35 U.S.C. 202(c)(4) does not constitute a license for the purposes of 
paragraphs (a)(2)(i) and (a)(3)(i) of this section.
    (5) Security Interest. A security interest does not involve an 
obligation to transfer rights in the invention for the purposes of 
paragraphs (a)(1) through (a)(3) of this section unless the security 
interest is defaulted upon.
    (b) Establishment of small entity status permits payment of reduced 
fees. (1) A small entity, as defined in paragraph (a) of this section, 
who has properly asserted entitlement to small entity status pursuant to 
paragraph (c) of this section will be accorded small entity status by 
the Office in the particular

[[Page 42]]

application or patent in which entitlement to small entity status was 
asserted. Establishment of small entity status allows the payment of 
certain reduced patent fees pursuant to 35 U.S.C. 41(h)(1).
    (2) Submission of an original utility application in compliance with 
the Office electronic filing system by an applicant who has properly 
asserted entitlement to small entity status pursuant to paragraph (c) of 
this section in that application allows the payment of a reduced filing 
fee pursuant to 35 U.S.C. 41(h)(3).
    (c) Assertion of small entity status. Any party (person, small 
business concern or nonprofit organization) should make a determination, 
pursuant to paragraph (f) of this section, of entitlement to be accorded 
small entity status based on the definitions set forth in paragraph (a) 
of this section, and must, in order to establish small entity status for 
the purpose of paying small entity fees, actually make an assertion of 
entitlement to small entity status, in the manner set forth in 
paragraphs (c)(1) or (c)(3) of this section, in the application or 
patent in which such small entity fees are to be paid.
    (1) Assertion by writing. Small entity status may be established by 
a written assertion of entitlement to small entity status. A written 
assertion must:
    (i) Be clearly identifiable;
    (ii) Be signed (see paragraph (c)(2) of this section); and
    (iii) Convey the concept of entitlement to small entity status, such 
as by stating that applicant is a small entity, or that small entity 
status is entitled to be asserted for the application or patent. While 
no specific words or wording are required to assert small entity status, 
the intent to assert small entity status must be clearly indicated in 
order to comply with the assertion requirement.
    (2) Parties who can sign the written assertion. The written 
assertion can be signed by:
    (i) The applicant (Sec. 1.42 or Sec. 1.421);
    (ii) A patent practitioner of record or a practitioner acting in a 
representative capacity under Sec. 1.34;
    (iii) The inventor or a joint inventor, if the inventor is the 
applicant; or
    (iv) The assignee.
    (3) Assertion by payment of the small entity basic filing, basic 
transmittal, basic national fee, international search fee, or individual 
designation fee in an international design application. The payment, by 
any party, of the exact amount of one of the small entity basic filing 
fees set forth in Sec. 1.16(a), (b), (c), (d), or (e), the small entity 
transmittal fee set forth in Sec. 1.445(a)(1), the small entity 
international search fee set forth in Sec. 1.445(a)(2) to a Receiving 
Office other than the United States Receiving Office in the exact amount 
established for that Receiving Office pursuant to PCT Rule 16, or the 
small entity basic national fee set forth in Sec. 1.492(a), will be 
treated as a written assertion of entitlement to small entity status 
even if the type of basic filing, basic transmittal, or basic national 
fee is inadvertently selected in error. The payment, by any party, of 
the small entity first part of the individual designation fee for the 
United States to the International Bureau (Sec. 1.1031) will be treated 
as a written assertion of entitlement to small entity status.
    (i) If the Office accords small entity status based on payment of a 
small entity basic filing or basic national fee under paragraph (c)(3) 
of this section that is not applicable to that application, any balance 
of the small entity fee that is applicable to that application will be 
due along with the appropriate surcharge set forth in Sec. 1.16(f), or 
Sec. 1.16(g).
    (ii) The payment of any small entity fee other than those set forth 
in paragraph (c)(3) of this section (whether in the exact fee amount or 
not) will not be treated as a written assertion of entitlement to small 
entity status and will not be sufficient to establish small entity 
status in an application or a patent.
    (4) Assertion required in related, continuing, and reissue 
applications. Status as a small entity must be specifically established 
by an assertion in each related, continuing and reissue application in 
which status is appropriate and desired. Status as a small entity in one 
application or patent does not affect the status of any other 
application or patent, regardless of the relationship of

[[Page 43]]

the applications or patents. The refiling of an application under 
Sec. 1.53 as a continuation, divisional, or continuation-in-part 
application (including a continued prosecution application under 
Sec. 1.53(d)), or the filing of a reissue application, requires a new 
assertion as to continued entitlement to small entity status for the 
continuing or reissue application.
    (d) When small entity fees can be paid. Any fee, other than the 
small entity basic filing fees and the small entity national fees of 
paragraph (c)(3) of this section, can be paid in the small entity amount 
only if it is submitted with, or subsequent to, the submission of a 
written assertion of entitlement to small entity status, except when 
refunds are permitted by Sec. 1.28(a).
    (e) Only one assertion required. (1) An assertion of small entity 
status need only be filed once in an application or patent. Small entity 
status, once established, remains in effect until changed pursuant to 
paragraph (g)(1) of this section. Where an assignment of rights or an 
obligation to assign rights to other parties who are small entities 
occurs subsequent to an assertion of small entity status, a second 
assertion is not required.
    (2) Once small entity status is withdrawn pursuant to paragraph 
(g)(2) of this section, a new written assertion is required to again 
obtain small entity status.
    (f) Assertion requires a determination of entitlement to pay small 
entity fees. Prior to submitting an assertion of entitlement to small 
entity status in an application, including a related, continuing, or 
reissue application, a determination of such entitlement should be made 
pursuant to the requirements of paragraph (a) of this section. It should 
be determined that all parties holding rights in the invention qualify 
for small entity status. The Office will generally not question any 
assertion of small entity status that is made in accordance with the 
requirements of this section, but note paragraph (h) of this section.
    (g)(1) New determination of entitlement to small entity status is 
needed when issue and maintenance fees are due. Once status as a small 
entity has been established in an application or patent, fees as a small 
entity may thereafter be paid in that application or patent without 
regard to a change in status until the issue fee is due or any 
maintenance fee is due.
    (2) Notification of loss of entitlement to small entity status is 
required when issue and maintenance fees are due. Notification of a loss 
of entitlement to small entity status must be filed in the application 
or patent prior to paying, or at the time of paying, the earliest of the 
issue fee or any maintenance fee due after the date on which status as a 
small entity as defined in paragraph (a) of this section is no longer 
appropriate. The notification that small entity status is no longer 
appropriate must be signed by a party identified in Sec. 1.33(b). 
Payment of a fee in other than the small entity amount is not sufficient 
notification that small entity status is no longer appropriate.
    (h) Fraud attempted or practiced on the Office. (1) Any attempt to 
fraudulently establish status as a small entity, or pay fees as a small 
entity, shall be considered as a fraud practiced or attempted on the 
Office.
    (2) Improperly, and with intent to deceive, establishing status as a 
small entity, or paying fees as a small entity, shall be considered as a 
fraud practiced or attempted on the Office.

Sec. 1.28  Refunds when small entity status is later established;
how errors in small entity status are excused.

    (a) Refunds based on later establishment of small entity status. A 
refund pursuant to Sec. 1.26, based on establishment of small entity 
status, of a portion of fees timely paid in full prior to establishing 
status as a small entity may only be obtained if an assertion under 
Sec. 1.27(c) and a request for a refund of the excess amount are filed 
within three months of the date of the timely payment of the full fee. 
The three-month time period is not extendable under Sec. 1.136. Status 
as a small entity is waived for any fee by the failure to establish the 
status prior to paying, at the time of paying, or within three

[[Page 44]]

months of the date of payment of, the full fee.
    (b) Date of payment. (1) The three-month period for requesting a 
refund, pursuant to paragraph (a) of this section, starts on the date 
that a full fee has been paid;
    (2) The date when a deficiency payment is paid in full determines 
the amount of deficiency that is due, pursuant to paragraph (c) of this 
section.
    (c) How errors in small entity status are excused. If status as a 
small entity is established in good faith, and fees as a small entity 
are paid in good faith, in any application or patent, and it is later 
discovered that such status as a small entity was established in error, 
or that through error the Office was not notified of a loss of 
entitlement to small entity status as required by Sec. 1.27(g)(2), the 
error will be excused upon: compliance with the separate submission and 
itemization requirements of paragraphs (c)(1) and (c)(2) of this 
section, and the deficiency payment requirement of paragraph (c)(2) of 
this section:
    (1) Separate submission required for each application or patent. Any 
paper submitted under this paragraph must be limited to the deficiency 
payment (all fees paid in error), required by paragraph (c)(2) of this 
section, for one application or one patent. Where more than one 
application or patent is involved, separate submissions of deficiency 
payments (e.g., checks) and itemizations are required for each 
application or patent. See Sec. 1.4(b).
    (2) Payment of deficiency owed. The deficiency owed, resulting from 
the previous erroneous payment of small entity fees, must be paid.
    (i) Calculation of the deficiency owed. The deficiency owed for each 
previous fee erroneously paid as a small entity is the difference 
between the current fee amount (for other than a small entity) on the 
date the deficiency is paid in full and the amount of the previous 
erroneous (small entity) fee payment. The total deficiency payment owed 
is the sum of the individual deficiency owed amounts for each fee amount 
previously erroneously paid as a small entity. Where a fee paid in error 
as a small entity was subject to a fee decrease between the time the fee 
was paid in error and the time the deficiency is paid in full, the 
deficiency owed is equal to the amount (previously) paid in error;
    (ii) Itemization of the deficiency payment. An itemization of the 
total deficiency payment is required. The itemization must include the 
following information:
    (A) Each particular type of fee that was erroneously paid as a small 
entity, (e.g., basic statutory filing fee, two-month extension of time 
fee) along with the current fee amount for a non-small entity;
    (B) The small entity fee actually paid, and when. This will permit 
the Office to differentiate, for example, between two one-month 
extension of time fees erroneously paid as a small entity but on 
different dates;
    (C) The deficiency owed amount (for each fee erroneously paid); and
    (D) The total deficiency payment owed, which is the sum or total of 
the individual deficiency owed amounts set forth in paragraph 
(c)(2)(ii)(C) of this section.
    (3) Failure to comply with requirements. If the requirements of 
paragraphs (c)(1) and (c)(2) of this section are not complied with, such 
failure will either: be treated as an authorization for the Office to 
process the deficiency payment and charge the processing fee set forth 
in Sec. 1.17(i), or result in a requirement for compliance within a one-
month non-extendable time period under Sec. 1.136(a) to avoid the return 
of the fee deficiency paper, at the option of the Office.
    (d) Payment of deficiency operates as notification of loss of 
status. Any deficiency payment (based on a previous erroneous payment of 
a small entity fee) submitted under paragraph (c) of this section will 
be treated under Sec. 1.27(g)(2) as a notification of a loss of 
entitlement to small entity status.

Sec. 1.29  Micro entity status.

    (a) To establish micro entity status under this paragraph, the 
applicant must certify that:
    (1) The applicant qualifies as a small entity as defined in 
Sec. 1.27;
    (2) Neither the applicant nor the inventor nor a joint inventor has 
been

[[Page 45]]

named as the inventor or a joint inventor on more than four previously 
filed patent applications, other than applications filed in another 
country, provisional applications under 35 U.S.C. 111(b), or 
international applications for which the basic national fee under 35 
U.S.C. 41(a) was not paid;
    (3) Neither the applicant nor the inventor nor a joint inventor, in 
the calendar year preceding the calendar year in which the applicable 
fee is being paid, had a gross income, as defined in section 61(a) of 
the Internal Revenue Code of 1986 (26 U.S.C. 61(a)), exceeding three 
times the median household income for that preceding calendar year, as 
most recently reported by the Bureau of the Census; and
    (4) Neither the applicant nor the inventor nor a joint inventor has 
assigned, granted, or conveyed, nor is under an obligation by contract 
or law to assign, grant, or convey, a license or other ownership 
interest in the application concerned to an entity that, in the calendar 
year preceding the calendar year in which the applicable fee is being 
paid, had a gross income, as defined in section 61(a) of the Internal 
Revenue Code of 1986, exceeding three times the median household income 
for that preceding calendar year, as most recently reported by the 
Bureau of the Census.
    (b) An applicant, inventor, or joint inventor is not considered to 
be named on a previously filed application for purposes of paragraph 
(a)(2) of this section if the applicant, inventor, or joint inventor has 
assigned, or is under an obligation by contract or law to assign, all 
ownership rights in the application as the result of the applicant's, 
inventor's, or joint inventor's previous employment.
    (c) If an applicant's, inventor's, joint inventor's, or entity's 
gross income in the preceding calendar year is not in United States 
dollars, the average currency exchange rate, as reported by the Internal 
Revenue Service, during that calendar year shall be used to determine 
whether the applicant's, inventor's, joint inventor's, or entity's gross 
income exceeds the threshold specified in paragraph (a)(3) or (4) of 
this section.
    (d) To establish micro entity status under this paragraph, the 
applicant must certify that:
    (1) The applicant qualifies as a small entity as defined in 
Sec. 1.27; and
    (2)(i) The applicant's employer, from which the applicant obtains 
the majority of the applicant's income, is an institution of higher 
education as defined in section 101(a) of the Higher Education Act of 
1965 (20 U.S.C. 1001(a)); or
    (ii) The applicant has assigned, granted, conveyed, or is under an 
obligation by contract or law, to assign, grant, or convey, a license or 
other ownership interest in the particular application to such an 
institution of higher education.
    (e) Micro entity status is established in an application by filing a 
micro entity certification in writing complying with the requirements of 
either paragraph (a) or (d) of this section and signed either in 
compliance with Sec. 1.33(b), in an international application filed in a 
Receiving Office other than the United States Receiving Office by a 
person authorized to represent the applicant under Sec. 1.455, or in an 
international design application by a person authorized to represent the 
applicant under Sec. 1.1041 before the International Bureau where the 
micro entity certification is filed with the International Bureau. 
Status as a micro entity must be specifically established in each 
related, continuing and reissue application in which status is 
appropriate and desired. Status as a micro entity in one application or 
patent does not affect the status of any other application or patent, 
regardless of the relationship of the applications or patents. The 
refiling of an application under Sec. 1.53 as a continuation, 
divisional, or continuation-in-part application (including a continued 
prosecution application under Sec. 1.53(d)), or the filing of a reissue 
application, requires a new certification of entitlement to micro entity 
status for the continuing or reissue application.
    (f) A fee may be paid in the micro entity amount only if it is 
submitted with, or subsequent to, the submission of a certification of 
entitlement to micro entity status.
    (g) A certification of entitlement to micro entity status need only 
be filed

[[Page 46]]

once in an application or patent. Micro entity status, once established, 
remains in effect until changed pursuant to paragraph (i) of this 
section. However, a fee may be paid in the micro entity amount only if 
status as a micro entity as defined in paragraph (a) or (d) of this 
section is appropriate on the date the fee is being paid. Where an 
assignment of rights or an obligation to assign rights to other parties 
who are micro entities occurs subsequent to the filing of a 
certification of entitlement to micro entity status, a second 
certification of entitlement to micro entity status is not required.
    (h) Prior to submitting a certification of entitlement to micro 
entity status in an application, including a related, continuing, or 
reissue application, a determination of such entitlement should be made 
pursuant to the requirements of this section. It should be determined 
that each applicant qualifies for micro entity status under paragraph 
(a) or (d) of this section, and that any other party holding rights in 
the invention qualifies for small entity status under Sec. 1.27. The 
Office will generally not question certification of entitlement to micro 
entity status that is made in accordance with the requirements of this 
section.
    (i) Notification of a loss of entitlement to micro entity status 
must be filed in the application or patent prior to paying, or at the 
time of paying, any fee after the date on which status as a micro entity 
as defined in paragraph (a) or (d) of this section is no longer 
appropriate. The notification that micro entity status is no longer 
appropriate must be signed by a party identified in Sec. 1.33(b). 
Payment of a fee in other than the micro entity amount is not sufficient 
notification that micro entity status is no longer appropriate. A 
notification that micro entity status is no longer appropriate will not 
be treated as a notification that small entity status is also no longer 
appropriate unless it also contains a notification of loss of 
entitlement to small entity status under Sec. 1.27(f)(2). Once a 
notification of a loss of entitlement to micro entity status is filed in 
the application or patent, a new certification of entitlement to micro 
entity status is required to again obtain micro entity status.
    (j) Any attempt to fraudulently establish status as a micro entity, 
or pay fees as a micro entity, shall be considered as a fraud practiced 
or attempted on the Office. Improperly, and with intent to deceive, 
establishing status as a micro entity, or paying fees as a micro entity, 
shall be considered as a fraud practiced or attempted on the Office.
    (k) If status as a micro entity is established in good faith in an 
application or patent, and fees as a micro entity are paid in good faith 
in the application or patent, and it is later discovered that such micro 
entity status either was established in error, or that the Office was 
not notified of a loss of entitlement to micro entity status as required 
by paragraph (i) of this section through error, the error will be 
excused upon compliance with the separate submission and itemization 
requirements of paragraph (k)(1) of this section and the deficiency 
payment requirement of paragraph (k)(2) of this section.
    (1) Any paper submitted under this paragraph must be limited to the 
deficiency payment (all fees paid in error) required for a single 
application or patent. Where more than one application or patent is 
involved, separate submissions of deficiency payments are required for 
each application or patent (see Sec. 1.4(b)). The paper must contain an 
itemization of the total deficiency payment for the single application 
or patent and include the following information:
    (i) Each particular type of fee that was erroneously paid as a micro 
entity, (e.g., basic statutory filing fee, two-month extension of time 
fee) along with the current fee amount for a small or non-small entity, 
as applicable;
    (ii) The micro entity fee actually paid, and the date on which it 
was paid;
    (iii) The deficiency owed amount (for each fee erroneously paid); 
and
    (iv) The total deficiency payment owed, which is the sum or total of 
the individual deficiency owed amounts as set forth in paragraph (k)(2) 
of this section.
    (2) The deficiency owed, resulting from the previous erroneous 
payment of micro entity fees, must be paid. The deficiency owed for each 
previous fee

[[Page 47]]

erroneously paid as a micro entity is the difference between the current 
fee amount for a small entity or non-small entity, as applicable, on the 
date the deficiency is paid in full and the amount of the previous 
erroneous micro entity fee payment. The total deficiency payment owed is 
the sum of the individual deficiency owed amounts for each fee amount 
previously and erroneously paid as a micro entity.
    (3) If the requirements of paragraphs (k)(1) and (2) of this section 
are not complied with, such failure will either be treated at the option 
of the Office as an authorization for the Office to process the 
deficiency payment and charge the processing fee set forth in 
Sec. 1.17(i), or result in a requirement for compliance within a one-
month time period that is not extendable under Sec. 1.136(a) to avoid 
the return of the fee deficiency payment.
    (4) Any deficiency payment (based on a previous erroneous payment of 
a micro entity fee) submitted under this paragraph will be treated as a 
notification of a loss of entitlement to micro entity status under 
paragraph (i) of this section.

     Prosecution of Application and Appointment of Attorney or Agent



Sec. 1.31  Applicant may be represented by one or more patent
practitioners or joint inventors.

    An applicant for patent may file and prosecute the applicant's own 
case, or the applicant may give power of attorney so as to be 
represented by one or more patent practitioners or joint inventors, 
except that a juristic entity (e.g., organizational assignee) must be 
represented by a patent practitioner even if the juristic entity is the 
applicant. The Office cannot aid in the selection of a patent 
practitioner.

[77 FR 48813, Aug. 14, 2012]



Sec. 1.32  Power of attorney.

    (a) Definitions. (1) Patent practitioner means a registered patent 
attorney or registered patent agent under Sec. 11.6.
    (2) Power of attorney means a written document by which a principal 
authorizes one or more patent practitioners or joint inventors to act on 
the principal's behalf.
    (3) Principal means the applicant (Sec. 1.42) for an application for 
patent and the patent owner for a patent, including a patent in a 
supplemental examination or reexamination proceeding. The principal 
executes a power of attorney designating one or more patent 
practitioners or joint inventors to act on the principal's behalf.
    (4) Revocation means the cancellation by the principal of the 
authority previously given to a patent practitioner or joint inventor to 
act on the principal's behalf.
    (5) Customer Number means a number that may be used to:
    (i) Designate the correspondence address of a patent application or 
patent such that the correspondence address for the patent application, 
patent or other patent proceeding would be the address associated with 
the Customer Number;
    (ii) Designate the fee address (Sec. 1.363) of a patent such that 
the fee address for the patent would be the address associated with the 
Customer Number; and
    (iii) Submit a list of patent practitioners such that those patent 
practitioners associated with the Customer Number would have power of 
attorney.
    (6) Patent practitioner of record means a patent practitioner who 
has been granted a power of attorney in an application, patent, or other 
proceeding in compliance with paragraph (b) of this section. The phrases 
practitioner of record and attorney or agent of record also mean a 
patent practitioner who has been granted a power of attorney in an 
application, patent, or other proceeding in compliance with paragraph 
(b) of this section.
    (b) A power of attorney must:
    (1) Be in writing;
    (2) Name one or more representatives in compliance with paragraph 
(c) of this section;

[[Page 48]]

    (3) Give the representative power to act on behalf of the principal; 
and
    (4) Be signed by the applicant for patent (Sec. 1.42) or the patent 
owner. A patent owner who was not the applicant under Sec. 1.46 must 
appoint any power of attorney in compliance with Secs. 3.71 and 3.73 of 
this chapter.
    (c) A power of attorney may only name as representative:
    (1) One or more joint inventors (Sec. 1.45);
    (2) Those registered patent practitioners associated with a Customer 
Number;
    (3) Ten or fewer patent practitioners, stating the name and 
registration number of each patent practitioner. Except as provided in 
paragraph (c)(1) or (c)(2) of this section, the Office will not 
recognize more than ten patent practitioners as being of record in an 
application or patent. If a power of attorney names more than ten patent 
practitioners, such power of attorney must be accompanied by a separate 
paper indicating which ten patent practitioners named in the power of 
attorney are to be recognized by the Office as being of record in the 
application or patent to which the power of attorney is directed.
    (d) A power of attorney from a prior national application for which 
benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 386(c) in a 
continuing application may have effect in the continuing application if 
a copy of the power of attorney from the prior application is filed in 
the continuing application unless:
    (1) The power of attorney was granted by the inventor; and
    (2) The continuing application names an inventor who was not named 
as an inventor in the prior application.
    (e) If the power of attorney was granted by the originally named 
inventive entity, and an added inventor pursuant to Sec. 1.48 does not 
provide a power of attorney consistent with the power of attorney 
granted by the originally named inventive entity, the addition of the 
inventor results in the loss of that power of attorney upon grant of the 
Sec. 1.48 request. This provision does not preclude a practitioner from 
acting pursuant to Sec. 1.34, if applicable.

Sec. 1.33  Correspondence respecting patent applications, patent
reexamination proceedings, and other proceedings.

    (a) Correspondence address and daytime telephone number. When filing 
an application, a correspondence address must be set forth in either an 
application data sheet (Sec. 1.76), or elsewhere, in a clearly 
identifiable manner, in any paper submitted with an application filing. 
If no correspondence address is specified, the Office may treat the 
mailing address of the first named inventor (if provided, see 
Secs. 1.76(b)(1) and 1.63(b)(2)) as the correspondence address. The 
Office will direct, or otherwise make available, all notices, official 
letters, and other communications relating to the application to the 
person associated with the correspondence address. For correspondence 
submitted via the Office's electronic filing system, however, an 
electronic acknowledgment receipt will be sent to the submitter. The 
Office will generally not engage in double correspondence with an 
applicant and a patent practitioner, or with more than one patent 
practitioner except as deemed necessary by the Director. If more than 
one correspondence address is specified, the Office will select one of 
the specified addresses for use as the correspondence address and, if 
given, may select the address associated with a Customer Number over a 
typed correspondence address. For the party to whom correspondence is to 
be addressed, a daytime telephone number should be supplied in a clearly 
identifiable manner and may be changed by any party who may change the 
correspondence address. The correspondence address may be changed by the 
parties set forth in paragraph (b)(1) or (b)(3) of this section. Prior 
to the appointment of any power of attorney under Sec. 1.32(b), the 
correspondence address may also be changed by any patent practitioner 
named in the application transmittal papers who acts in a representative 
capacity under the provisions of Sec. 1.34.

[[Page 49]]

    (b) Amendments and other papers. Amendments and other papers, except 
for written assertions pursuant to Sec. 1.27(c)(2)(iii) or (c)(2)(iv), 
filed in the application must be signed by:
    (1) A patent practitioner of record;
    (2) A patent practitioner not of record who acts in a representative 
capacity under the provisions of Sec. 1.34; or
    (3) The applicant (Sec. 1.42). Unless otherwise specified, all 
papers submitted on behalf of a juristic entity must be signed by a 
patent practitioner.
    (c) All notices, official letters, and other communications for the 
patent owner or owners in a reexamination or supplemental examination 
proceeding will be directed to the correspondence address in the patent 
file. Amendments filed in a reexamination proceeding, and other papers 
filed in a reexamination or supplemental examination proceeding, on 
behalf of the patent owner must be signed by the patent owner, or if 
there is more than one owner by all the owners, or by an attorney or 
agent of record in the patent file, or by a registered attorney or agent 
not of record who acts in a representative capacity under the provisions 
of Sec. 1.34. Double correspondence with the patent owner or owners and 
the patent owner's attorney or agent, or with more than one attorney or 
agent, will not be undertaken.
    (d) A ``correspondence address'' or change thereto may be filed with 
the Patent and Trademark Office during the enforceable life of the 
patent. The ``correspondence address'' will be used in any 
correspondence relating to maintenance fees unless a separate ``fee 
address'' has been specified. See Sec. 1.363 for ``fee address'' used 
solely for maintenance fee purposes.
    (e) A change of address filed in a patent application or patent does 
not change the address for a patent practitioner in the roster of patent 
attorneys and agents. See Sec. 11.11 of this title.
    (f) Where application papers from a prior application are used in a 
continuing application and the correspondence address was changed during 
the prosecution of the prior application, an application data sheet or 
separate paper identifying the correspondence address to be used for the 
continuing application must be submitted. Otherwise, the Office may not 
recognize the change of correspondence address effected during the 
prosecution of the prior application.
    (g) A patent practitioner acting in a representative capacity whose 
correspondence address is the correspondence address of record in an 
application may change the correspondence address after the patent has 
issued, provided that the change of correspondence address is 
accompanied by a statement that notice has been given to the patentee or 
owner.

Sec. 1.34  Acting in a representative capacity.

    When a patent practitioner acting in a representative capacity 
appears in person or signs a paper in practice before the United States 
Patent and Trademark Office in a patent case, his or her personal 
appearance or signature shall constitute a representation to the United 
States Patent and Trademark Office that under the provisions of this 
subchapter and the law, he or she is authorized to represent the 
particular party on whose behalf he or she acts. In filing such a paper, 
the patent practitioner must set forth his or her registration number, 
his or her name and signature. Further proof of authority to act in a 
representative capacity may be required.

Sec. 1.36  Revocation of power of attorney; withdrawal of patent
attorney or agent.

    (a) A power of attorney, pursuant to Sec. 1.32(b), may be revoked at 
any stage in the proceedings of a case by the applicant or patent owner. 
A power of attorney to the patent practitioners associated with a 
Customer Number will be treated as a request to revoke any powers of 
attorney previously given. Fewer than all of the applicants (or

[[Page 50]]

fewer than all patent owners in a supplemental examination or 
reexamination proceeding) may revoke the power of attorney only upon a 
showing of sufficient cause, and payment of the petition fee set forth 
in Sec. 1.17(f). A patent practitioner will be notified of the 
revocation of the power of attorney. Where power of attorney is given to 
the patent practitioners associated with a Customer Number 
(Sec. 1.32(c)(2)), the practitioners so appointed will also be notified 
of the revocation of the power of attorney when the power of attorney to 
all of the practitioners associated with the Customer Number is revoked. 
The notice of revocation will be mailed to the correspondence address 
for the application (Sec. 1.33) in effect before the revocation. An 
assignment will not of itself operate as a revocation of a power 
previously given, but the assignee may become the applicant under 
Sec. 1.46(c) and revoke any previous power of attorney and grant a power 
of attorney as provided in Sec. 1.32(b).
    (b) A registered patent attorney or patent agent who has been given 
a power of attorney pursuant to Sec. 1.32(b) may withdraw as attorney or 
agent of record upon application to and approval by the Director. The 
applicant or patent owner will be notified of the withdrawal of the 
registered patent attorney or patent agent. Where power of attorney is 
given to the patent practitioners associated with a Customer Number, a 
request to delete all of the patent practitioners associated with the 
Customer Number may not be granted if an applicant has given power of 
attorney to the patent practitioners associated with the Customer Number 
in an application that has an Office action to which a reply is due, but 
insufficient time remains for the applicant to file a reply. See 
Sec. 41.5 of this title for withdrawal during proceedings before the 
Patent Trial and Appeal Board.

                       Who May Apply for a Patent



Sec. 1.41  Inventorship.

    (a) An application must include, or be amended to include, the name 
of the inventor for any invention claimed in the application.
    (b) The inventorship of a nonprovisional application under 35 U.S.C. 
111(a) is the inventor or joint inventors set forth in the application 
data sheet in accordance with Sec. 1.76 filed before or concurrently 
with the inventor's oath or declaration. If an application data sheet is 
not filed before or concurrently with the inventor's oath or 
declaration, the inventorship is the inventor or joint inventors set 
forth in the inventor's oath or declaration, except as provided for in 
Secs. 1.53(d)(4) and 1.63(d). Once an application data sheet or the 
inventor's oath or declaration is filed in a nonprovisional application, 
any correction of inventorship must be pursuant to Sec. 1.48. If neither 
an application data sheet nor the inventor's oath or declaration is 
filed during the pendency of a nonprovisional application, the 
inventorship is the inventor or joint inventors set forth in the 
application papers filed pursuant to Sec. 1.53(b), unless the applicant 
files a paper, including the processing fee set forth in Sec. 1.17(i), 
supplying the name or names of the inventor or joint inventors.
    (c) The inventorship of a provisional application is the inventor or 
joint inventors set forth in the cover sheet as prescribed by 
Sec. 1.51(c)(1). Once a cover sheet as prescribed by Sec. 1.51(c)(1) is 
filed in a provisional application, any correction of inventorship must 
be pursuant to Sec. 1.48. If a cover sheet as prescribed by 
Sec. 1.51(c)(1) is not filed during the pendency of a provisional 
application, the inventorship is the inventor or joint inventors set 
forth in the application papers filed pursuant to Sec. 1.53(c), unless 
applicant files a paper including the processing fee set forth in 
Sec. 1.17(q), supplying the name or names of the inventor or joint 
inventors.
    (d) In a nonprovisional application under 35 U.S.C. 111(a) filed 
without an application data sheet or the inventor's oath or declaration, 
or in a provisional application filed without a cover sheet as 
prescribed by Sec. 1.51(c)(1), the name and residence of each person 
believed to be an actual inventor should be provided when the 
application papers pursuant to Sec. 1.53(b) or Sec. 1.53(c) are filed.

[[Page 51]]

    (e) The inventorship of an international application entering the 
national stage under 35 U.S.C. 371 is the inventor or joint inventors 
set forth in the application data sheet in accordance with Sec. 1.76 
filed with the initial submission under 35 U.S.C. 371. Unless the 
initial submission under 35 U.S.C. 371 is accompanied by an application 
data sheet in accordance with Sec. 1.76 setting forth the inventor or 
joint inventors, the inventorship is the inventor or joint inventors set 
forth in the international application, which includes any change 
effected under PCT Rule 92 bis.
    (f) The inventorship of an international design application 
designating the United States is the creator or creators set forth in 
the publication of the international registration under Hague Agreement 
Article 10(3). Any correction of inventorship must be pursuant to 
Sec. 1.48.

[77 FR 48814, Aug. 14, 2012, as amended at 80 FR 17956, Apr. 2, 2015]



Sec. 1.42  Applicant for patent.

    (a) The word ``applicant'' when used in this title refers to the 
inventor or all of the joint inventors, or to the person applying for a 
patent as provided in Secs. 1.43, 1.45, or 1.46.
    (b) If a person is applying for a patent as provided in Sec. 1.46, 
the word ``applicant'' refers to the assignee, the person to whom the 
inventor is under an obligation to assign the invention, or the person 
who otherwise shows sufficient proprietary interest in the matter, who 
is applying for a patent under Sec. 1.46 and not the inventor.
    (c) If fewer than all joint inventors are applying for a patent as 
provided in Sec. 1.45, the phrase ``the applicant'' means the joint 
inventors who are applying for the patent without the omitted 
inventor(s).
    (d) Any person having authority may deliver an application and fees 
to the Office on behalf of the applicant. However, an oath or 
declaration, or substitute statement in lieu of an oath or declaration, 
may be executed only in accordance with Sec. 1.63 or 1.64, a 
correspondence address may be provided only in accordance with 
Sec. 1.33(a), and amendments and other papers must be signed in 
accordance with Sec. 1.33(b).
    (e) The Office may require additional information where there is a 
question concerning ownership or interest in an application, and a 
showing may be required from the person filing the application that the 
filing was authorized where such authorization comes into question.

[77 FR 48815, Aug. 14, 2012]



Sec. 1.43  Application for patent by a legal representative of a 
deceased or legally incapacitated inventor.

    If an inventor is deceased or under legal incapacity, the legal 
representative of the inventor may make an application for patent on 
behalf of the inventor. If an inventor dies during the time intervening 
between the filing of the application and the granting of a patent 
thereon, the letters patent may be issued to the legal representative 
upon proper intervention. See Sec. 1.64 concerning the execution of a 
substitute statement by a legal representative in lieu of an oath or 
declaration.

[77 FR 48815, Aug. 14, 2012]



Sec. 1.44  [Reserved]



Sec. 1.45  Application for patent by joint inventors.

    (a) Joint inventors must apply for a patent jointly, and each must 
make an inventor's oath or declaration as required by Sec. 1.63, except 
as provided for in Sec. 1.64. If a joint inventor refuses to join in an 
application for patent or cannot be found or reached after diligent 
effort, the other joint inventor or inventors may make the application 
for patent on behalf of themselves and the omitted inventor. See 
Sec. 1.64 concerning the execution of a substitute statement by the 
other joint inventor or inventors in lieu of an oath or declaration.
    (b) Inventors may apply for a patent jointly even though:
    (1) They did not physically work together or at the same time;
    (2) Each inventor did not make the same type or amount of 
contribution; or
    (3) Each inventor did not make a contribution to the subject matter 
of every claim of the application.
    (c) If multiple inventors are named in a nonprovisional application, 
each

[[Page 52]]

named inventor must have made a contribution, individually or jointly, 
to the subject matter of at least one claim of the application and the 
application will be considered to be a joint application under 35 U.S.C. 
116. If multiple inventors are named in a provisional application, each 
named inventor must have made a contribution, individually or jointly, 
to the subject matter disclosed in the provisional application and the 
provisional application will be considered to be a joint application 
under 35 U.S.C. 116.

[77 FR 48815, Aug. 14, 2012]



Sec. 1.46  Application for patent by an assignee, obligated assignee, 
or a person who otherwise shows sufficient proprietary interest in the
matter.

    (a) A person to whom the inventor has assigned or is under an 
obligation to assign the invention may make an application for patent. A 
person who otherwise shows sufficient proprietary interest in the matter 
may make an application for patent on behalf of and as agent for the 
inventor on proof of the pertinent facts and a showing that such action 
is appropriate to preserve the rights of the parties.
    (b) If an application under 35 U.S.C. 111 is made by a person other 
than the inventor under paragraph (a) of this section, the application 
must contain an application data sheet under Sec. 1.76 specifying in the 
applicant information section (Sec. 1.76(b)(7)) the assignee, person to 
whom the inventor is under an obligation to assign the invention, or 
person who otherwise shows sufficient proprietary interest in the 
matter. If an application entering the national stage under 35 U.S.C. 
371, or a nonprovisional international design application, is applied 
for by a person other than the inventor under paragraph (a) of this 
section, the assignee, person to whom the inventor is under an 
obligation to assign the invention, or person who otherwise shows 
sufficient proprietary interest in the matter must have been identified 
as the applicant for the United States in the international stage of the 
international application or as the applicant in the publication of the 
international registration under Hague Agreement Article 10(3).
    (1) If the applicant is the assignee or a person to whom the 
inventor is under an obligation to assign the invention, documentary 
evidence of ownership (e.g., assignment for an assignee, employment 
agreement for a person to whom the inventor is under an obligation to 
assign the invention) should be recorded as provided for in part 3 of 
this chapter no later than the date the issue fee is paid in the 
application.
    (2) If the applicant is a person who otherwise shows sufficient 
proprietary interest in the matter, such applicant must submit a 
petition including:
    (i) The fee set forth in Sec. 1.17(g);
    (ii) A showing that such person has sufficient proprietary interest 
in the matter; and
    (iii) A statement that making the application for patent by a person 
who otherwise shows sufficient proprietary interest in the matter on 
behalf of and as agent for the inventor is appropriate to preserve the 
rights of the parties.
    (c)(1) Correction or update in the name of the applicant. Any 
request to correct or update the name of the applicant under this 
section must include an application data sheet under Sec. 1.76 
specifying the correct or updated name of the applicant in the applicant 
information section (Sec. 1.76(b)(7)) in accordance with 
Sec. 1.76(c)(2). A change in the name of the applicant recorded pursuant 
to Hague Agreement Article 16(1)(ii) will be effective to change the 
name of the applicant in a nonprovisional international design 
application.
    (2) Change in the applicant. Any request to change the applicant 
under this section after an original applicant has been specified must 
include an application data sheet under Sec. 1.76 specifying the 
applicant in the applicant information section (Sec. 1.76(b)(7)) in 
accordance with Sec. 1.76(c)(2) and comply with Secs. 3.71 and 3.73 of 
this title.
    (d) Even if the whole or a part interest in the invention or in the 
patent to be issued is assigned or obligated to be assigned, an oath or 
declaration must be executed by the actual inventor or each actual joint 
inventor, except as provided for in Sec. 1.64. See Sec. 1.64 concerning 
the execution of a substitute statement by an assignee, person to

[[Page 53]]

whom the inventor is under an obligation to assign the invention, or a 
person who otherwise shows sufficient proprietary interest in the 
matter.
    (e) If a patent is granted on an application filed under this 
section by a person other than the inventor, the patent shall be granted 
to the real party in interest. Otherwise, the patent may be issued to 
the assignee or jointly to the inventor and the assignee as provided in 
Sec. 3.81. Where a real party in interest has filed an application under 
Sec. 1.46, the applicant shall notify the Office of any change in the 
real party in interest no later than payment of the issue fee. The 
Office will treat the absence of such a notice as an indication that 
there has been no change in the real party in interest.
    (f) The Office may publish notice of the filing of the application 
by a person who otherwise shows sufficient proprietary interest in the 
Official Gazette.

    (4) The abstract must commence on a separate physical sheet or 
electronic page or be submitted as the first page of the patent in a 
reissue application or reexamination or supplemental examination 
proceeding (Sec. 1.72(b)).
    (5) Other than in a reissue application or a reexamination or 
supplemental examination proceeding, the pages of the specification 
including claims and abstract must be numbered consecutively, starting 
with 1, the numbers being centrally located above or preferably, below, 
the text.
    (6) Other than in a reissue application or reexamination or 
supplemental examination proceeding, the paragraphs of the 
specification, other than in the claims or abstract, may be numbered at 
the time the application is filed, and should be individually and 
consecutively numbered using Arabic numerals, so as to unambiguously 
identify each paragraph. The number should consist of at least four 
numerals enclosed in square brackets, including leading zeros (e.g., 
[0001]). The numbers and enclosing brackets should appear to the right 
of the left margin as the first item in each paragraph, before the first 
word of the paragraph, and should be highlighted in bold. A gap, 
equivalent to approximately four spaces, should follow the number. 
Nontext elements (e.g., tables, mathematical or chemical formulae, 
chemical structures, and sequence data) are considered part of the 
numbered paragraph around or above the elements, and should not be 
independently numbered. If a nontext element extends to the left margin, 
it should not be numbered as a separate and independent paragraph. A 
list is also treated as part of the paragraph around or above the list, 
and should not be independently numbered. Paragraph or section headers 
(titles), whether abutting the left margin or centered on the page, are 
not considered paragraphs and should not be numbered.
    (c) Interlineation, erasure, cancellation, or other alteration of 
the application papers may be made before or after the signing of the 
inventor's oath

[[Page 56]]

or declaration referring to those application papers, provided that the 
statements in the inventor's oath or declaration pursuant to Sec. 1.63 
remain applicable to those application papers. A substitute 
specification (Sec. 1.125) may be required if the application papers do 
not comply with paragraphs (a) and (b) of this section.
    (d) A nonprovisional or provisional application under 35 U.S.C. 111 
may be in a language other than English.
    (1) Nonprovisional application. If a nonprovisional application 
under 35 U.S.C. 111(a) is filed in a language other than English, an 
English language translation of the non-English language application, a 
statement that the translation is accurate, and the processing fee set 
forth in Sec. 1.17(i) are required. If these items are not filed with 
the application, the applicant will be notified and given a period of 
time within which they must be filed in order to avoid abandonment.
    (2) Provisional application. If a provisional application under 35 
U.S.C. 111(b) is filed in a language other than English, an English 
language translation of the non-English language provisional application 
will not be required in the provisional application. See Sec. 1.78(a) 
for the requirements for claiming the benefit of such provisional 
application in a nonprovisional application.
    (e) Electronic documents that are to become part of the permanent 
United States Patent and Trademark Office records in the file of a 
patent application, or reexamination or supplemental examination 
proceeding. (1) The following documents may be submitted to the Office 
on a compact disc in compliance with this paragraph:
    (i) A computer program listing (see Sec. 1.96);
    (ii) A ``Sequence Listing'' (submitted under Sec. 1.821(c)); or
    (iii) Any individual table (see Sec. 1.58) if the table is more than 
50 pages in length, or if the total number of pages of all the tables in 
an application exceeds 100 pages in length, where a table page is a page 
printed on paper in conformance with paragraph (b) of this section and 
Sec. 1.58(c).
    (2) A compact disc as used in this part means a Compact Disc-Read 
Only Memory (CD-ROM) or a Compact Disc-Recordable (CD-R) in compliance 
with this paragraph. A CD-ROM is a ``read-only'' medium on which the 
data is pressed into the disc so that it cannot be changed or erased. A 
CD-R is a ``write once'' medium on which once the data is recorded, it 
is permanent and cannot be changed or erased.
    (3)(i) Each compact disc must conform to the International 
Organization for Standardization (ISO) 9660 standard, and the contents 
of each compact disc must be in compliance with the American Standard 
Code for Information Interchange (ASCII).
    (ii) Each compact disc must be enclosed in a hard compact disc case 
within an unsealed padded and protective mailing envelope and 
accompanied by a transmittal letter on paper in accordance with 
paragraph (a) of this section. The transmittal letter must list for each 
compact disc the machine format (e.g., IBM-PC, Macintosh), the operating 
system compatibility (e.g., MS-DOS, MS-Windows, Macintosh, Unix), a list 
of files contained on the compact disc including their names, sizes in 
bytes, and dates of creation, plus any other special information that is 
necessary to identify, maintain, and interpret (e.g., tables in 
landscape orientation should be identified as landscape orientation or 
be identified when inquired about) the information on the compact disc. 
Compact discs submitted to the Office will not be returned to the 
applicant.
    (4) Any compact disc must be submitted in duplicate unless it 
contains only the ``Sequence Listing'' in computer readable form 
required by Sec. 1.821(e). The compact disc and duplicate copy must be 
labeled ``Copy 1'' and ``Copy 2,'' respectively. The transmittal letter 
which accompanies the compact disc must include a statement that the two 
compact discs are identical. In the event that the two compact discs are 
not identical, the Office will use the compact disc labeled ``Copy 1'' 
for further processing. Any amendment to the information on a compact 
disc must be by way of a replacement compact disc in compliance with 
this paragraph containing the substitute information, and must be 
accompanied by a statement that the

[[Page 57]]

replacement compact disc contains no new matter. The compact disc and 
copy must be labeled ``COPY 1 REPLACEMENT MM/DD/YYYY'' (with the month, 
day and year of creation indicated), and ``COPY 2 REPLACEMENT MM/DD/
YYYY,'' respectively.
    (5) The specification must contain an incorporation-by-reference of 
the material on the compact disc in a separate paragraph 
(Sec. 1.77(b)(5)), identifying each compact disc by the names of the 
files contained on each of the compact discs, their date of creation and 
their sizes in bytes. The Office may require applicant to amend the 
specification to include in the paper portion any part of the 
specification previously submitted on compact disc.
    (6) A compact disc must also be labeled with the following 
information:
    (i) The name of each inventor (if known);
    (ii) Title of the invention;
    (iii) The docket number, or application number if known, used by the 
person filing the application to identify the application;
    (iv) A creation date of the compact disc;
    (v) If multiple compact discs are submitted, the label shall 
indicate their order (e.g., ``1 of X''); and
    (vi) An indication that the disc is ``Copy 1'' or ``Copy 2'' of the 
submission. See paragraph (b)(4) of this section.
    (7) If a file is unreadable on both copies of the disc, the 
unreadable file will be treated as not having been submitted. A file is 
unreadable if, for example, it is of a format that does not comply with 
the requirements of paragraph (e)(3) of this section, it is corrupted by 
a computer virus, or it is written onto a defective compact disc.
    (f)(1) Any sequence listing in an electronic medium in compliance 
with Secs. 1.52(e) and 1.821(c) or (e), and any computer program listing 
filed in an electronic medium in compliance with Secs. 1.52(e) and 1.96, 
will be excluded when determining the application size fee required by 
Sec. 1.16(s) or Sec. 1.492(j). For purposes of determining the 
application size fee required by Sec. 1.16(s) or Sec. 1.492(j), for an 
application the specification and drawings of which, excluding any 
sequence listing in compliance with Sec. 1.821(c) or (e), and any 
computer program listing filed in an electronic medium in compliance 
with Secs. 1.52(e) and 1.96, are submitted in whole or in part on an 
electronic medium other than the Office electronic filing system, each 
three kilobytes of content submitted on an electronic medium shall be 
counted as a sheet of paper.
    (2) Except as otherwise provided in this paragraph, the paper size 
equivalent of the specification and drawings of an application submitted 
via the Office electronic filing system will be considered to be 
seventy-five percent of the number of sheets of paper present in the 
specification and drawings of the application when entered into the 
Office file wrapper after being rendered by the Office electronic filing 
system for purposes of determining the application size fee required by 
Sec. 1.16(s). Any sequence listing in compliance with Sec. 1.821(c) or 
(e), and any computer program listing in compliance with Sec. 1.96, 
submitted via the Office electronic filing system will be excluded when 
determining the application size fee required by Sec. 1.16(s) if the 
listing is submitted in ASCII text as part of an associated file.

Sec. 1.53  Application number, filing date, and completion of application.

    (a) Application number. Any papers received in the Patent and 
Trademark Office which purport to be an application for a patent will be 
assigned an application number for identification purposes.
    (b) Application filing requirements--Nonprovisional application. The 
filing date of an application for patent filed under this section, other 
than an application for a design patent or a provisional application 
under paragraph (c) of this section, is the date on which a 
specification, with or without claims, is received in the Office. The 
filing date of an application for a design patent filed under this 
section, except for a

[[Page 58]]

continued prosecution application under paragraph (d) of this section, 
is the date on which the specification as prescribed by 35 U.S.C. 112, 
including at least one claim, and any required drawings are received in 
the Office. No new matter may be introduced into an application after 
its filing date. A continuing application, which may be a continuation, 
divisional, or continuation-in-part application, may be filed under the 
conditions specified in 35 U.S.C. 120, 121, 365(c), or 386(c) and 
Sec. 1.78.
    (1) A continuation or divisional application that names as inventors 
the same or fewer than all of the inventors named in the prior 
application may be filed under this paragraph or paragraph (d) of this 
section.
    (2) A continuation-in-part application (which may disclose and claim 
subject matter not disclosed in the prior application) or a continuation 
or divisional application naming an inventor not named in the prior 
application must be filed under this paragraph.
    (c) Application filing requirements--Provisional application. The 
filing date of a provisional application is the date on which a 
specification, with or without claims, is received in the Office. No 
amendment, other than to make the provisional application comply with 
the patent statute and all applicable regulations, may be made to the 
provisional application after the filing date of the provisional 
application.
    (1) A provisional application must also include the cover sheet 
required by Sec. 1.51(c)(1), which may be an application data sheet 
(Sec. 1.76), or a cover letter identifying the application as a 
provisional application. Otherwise, the application will be treated as 
an application filed under paragraph (b) of this section.
    (2) An application for patent filed under paragraph (b) of this 
section may be converted to a provisional application and be accorded 
the original filing date of the application filed under paragraph (b) of 
this section. The grant of such a request for conversion will not 
entitle applicant to a refund of the fees that were properly paid in the 
application filed under paragraph (b) of this section. Such a request 
for conversion must be accompanied by the processing fee set forth in 
Sec. 1.17(q) and be filed prior to the earliest of:
    (i) Abandonment of the application filed under paragraph (b) of this 
section;
    (ii) Payment of the issue fee on the application filed under 
paragraph (b) of this section; or
    (iii) Expiration of twelve months after the filing date of the 
application filed under paragraph (b) of this section.
    (3) A provisional application filed under paragraph (c) of this 
section may be converted to a nonprovisional application filed under 
paragraph (b) of this section and accorded the original filing date of 
the provisional application. The conversion of a provisional application 
to a nonprovisional application will not result in either the refund of 
any fee properly paid in the provisional application or the application 
of any such fee to the filing fee, or any other fee, for the 
nonprovisional application. Conversion of a provisional application to a 
nonprovisional application under this paragraph will result in the term 
of any patent to issue from the application being measured from at least 
the filing date of the provisional application for which conversion is 
requested. Thus, applicants should consider avoiding this adverse patent 
term impact by filing a nonprovisional application claiming the benefit 
of the provisional application under 35 U.S.C. 119(e), rather than 
converting the provisional application into a nonprovisional application 
pursuant to this paragraph. A request to convert a provisional 
application to a nonprovisional application must be accompanied by the 
fee set forth in Sec. 1.17(i) and an amendment including at least one 
claim as prescribed by 35 U.S.C. 112(b), unless the provisional 
application under paragraph (c) of this section otherwise contains at 
least one claim as prescribed by 35 U.S.C. 112(b). The nonprovisional 
application resulting from conversion of a provisional application must 
also include the filing fee, search fee, and examination fee for a 
nonprovisional application, and the surcharge required by Sec. 1.16(f) 
if either the basic filing fee for a nonprovisional application or the 
inventor's oath or declaration was not

[[Page 59]]

present on the filing date accorded the resulting nonprovisional 
application (i.e., the filing date of the original provisional 
application). A request to convert a provisional application to a 
nonprovisional application must also be filed prior to the earliest of:
    (i) Abandonment of the provisional application filed under paragraph 
(c) of this section; or
    (ii) Expiration of twelve months after the filing date of the 
provisional application filed under paragraph (c) of this section.
    (4) A provisional application is not entitled to the right of 
priority under 35 U.S.C. 119, 365(a), or 386(a) or Sec. 1.55, or to the 
benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 
386(c) or Sec. 1.78 of any other application. No claim for priority 
under 35 U.S.C. 119(e) or Sec. 1.78(a) may be made in a design 
application based on a provisional application. The requirements of 
Secs. 1.821 through 1.825 regarding application disclosures containing 
nucleotide and/or amino acid sequences are not mandatory for provisional 
applications.
    (d) Application filing requirements--Continued prosecution 
(nonprovisional) application. (1) A continuation or divisional 
application (but not a continuation-in-part) of a prior nonprovisional 
application may be filed as a continued prosecution application under 
this paragraph, provided that:
    (i) The application is for a design patent;
    (ii) The prior nonprovisional application is a design application, 
but not an international design application, that is complete as defined 
by Sec. 1.51(b), except for the inventor's oath or declaration if the 
application is filed on or after September 16, 2012, and the prior 
nonprovisional application contains an application data sheet meeting 
the conditions specified in Sec. 1.53(f)(3)(i); and
    (iii) The application under this paragraph is filed before the 
earliest of:
    (A) Payment of the issue fee on the prior application, unless a 
petition under Sec. 1.313(c) is granted in the prior application;
    (B) Abandonment of the prior application; or
    (C) Termination of proceedings on the prior application.
    (2) The filing date of a continued prosecution application is the 
date on which a request on a separate paper for an application under 
this paragraph is filed. An application filed under this paragraph:
    (i) Must identify the prior application;
    (ii) Discloses and claims only subject matter disclosed in the prior 
application;
    (iii) Names as inventors the same inventors named in the prior 
application on the date the application under this paragraph was filed, 
except as provided in paragraph (d)(4) of this section;
    (iv) Includes the request for an application under this paragraph, 
will utilize the file jacket and contents of the prior application, 
including the specification, drawings and the inventor's oath or 
declaration from the prior application, to constitute the new 
application, and will be assigned the application number of the prior 
application for identification purposes; and
    (v) Is a request to expressly abandon the prior application as of 
the filing date of the request for an application under this paragraph.
    (3) The filing fee, search fee, and examination fee for a continued 
prosecution application filed under this paragraph are the basic filing 
fee as set forth in Sec. 1.16(b), the search fee as set forth in 
Sec. 1.16(l), and the examination fee as set forth in Sec. 1.16(p).
    (4) An application filed under this paragraph may be filed by fewer 
than all the inventors named in the prior application, provided that the 
request for an application under this paragraph when filed is 
accompanied by a statement requesting deletion of the name or names of 
the person or persons who are not inventors of the invention being 
claimed in the new application. No person may be named as an inventor in 
an application filed under this paragraph who was not named as an 
inventor in the prior application on the date the application under this 
paragraph was filed, except by way of correction of inventorship under 
Sec. 1.48.
    (5) Any new change must be made in the form of an amendment to the 
prior application as it existed prior to the filing of an application 
under this paragraph. No amendment in an application

[[Page 60]]

under this paragraph (a continued prosecution application) may introduce 
new matter or matter that would have been new matter in the prior 
application. Any new specification filed with the request for an 
application under this paragraph will not be considered part of the 
original application papers, but will be treated as a substitute 
specification in accordance with Sec. 1.125.
    (6) The filing of a continued prosecution application under this 
paragraph will be construed to include a waiver of confidentiality by 
the applicant under 35 U.S.C. 122 to the extent that any member of the 
public, who is entitled under the provisions of Sec. 1.14 to access to, 
copies of, or information concerning either the prior application or any 
continuing application filed under the provisions of this paragraph, may 
be given similar access to, copies of, or similar information concerning 
the other application or applications in the file jacket.
    (7) A request for an application under this paragraph is the 
specific reference required by 35 U.S.C. 120 to every application 
assigned the application number identified in such request. No amendment 
in an application under this paragraph may delete this specific 
reference to any prior application.
    (8) In addition to identifying the application number of the prior 
application, applicant should furnish in the request for an application 
under this paragraph the following information relating to the prior 
application to the best of his or her ability:
    (i) Title of invention;
    (ii) Name of applicant(s); and
    (iii) Correspondence address.
    (9) See Sec. 1.103(b) for requesting a limited suspension of action 
in an application filed under this paragraph.
    (e) Failure to meet filing date requirements. (1) If an application 
deposited under paragraph (b), (c), or (d) of this section does not meet 
the requirements of such paragraph to be entitled to a filing date, 
applicant will be so notified, if a correspondence address has been 
provided, and given a period of time within which to correct the filing 
error. If, however, a request for an application under paragraph (d) of 
this section does not meet the requirements of that paragraph because 
the application in which the request was filed is not a design 
application, and if the application in which the request was filed was 
itself filed on or after June 8, 1995, the request for an application 
under paragraph (d) of this section will be treated as a request for 
continued examination under Sec. 1.114.
    (2) Any request for review of a notification pursuant to paragraph 
(e)(1) of this section, or a notification that the original application 
papers lack a portion of the specification or drawing(s), must be by way 
of a petition pursuant to this paragraph accompanied by the fee set 
forth in Sec. 1.17(f). In the absence of a timely (Sec. 1.181(f)) 
petition pursuant to this paragraph, the filing date of an application 
in which the applicant was notified of a filing error pursuant to 
paragraph (e)(1) of this section will be the date the filing error is 
corrected.
    (3) If an applicant is notified of a filing error pursuant to 
paragraph (e)(1) of this section, but fails to correct the filing error 
within the given time period or otherwise timely (Sec. 1.181(f)) take 
action pursuant to this paragraph, proceedings in the application will 
be considered terminated. Where proceedings in an application are 
terminated pursuant to this paragraph, the application may be disposed 
of, and any filing fees, less the handling fee set forth in 
Sec. 1.21(n), will be refunded.
    (f) Completion of application subsequent to filing--Nonprovisional 
(including continued prosecution or reissue) application. (1) If an 
application which has been accorded a filing date pursuant to paragraph 
(b) or (d) of this section does not include the basic filing fee, search 
fee, or examination fee, or if an application which has been accorded a 
filing date pursuant to paragraph (b) of this section does not include 
at least one claim or the inventor's oath or declaration (Secs. 1.63, 
1.64, 1.162, or 1.175), and the applicant has provided a correspondence 
address (Sec. 1.33(a)), the applicant will be notified and given a 
period of time within which to file a claim or claims, pay the basic 
filing fee, search fee, and examination fee, and pay the surcharge if 
required by Sec. 1.16(f), to avoid abandonment.

[[Page 61]]

    (2) If an application which has been accorded a filing date pursuant 
to paragraph (b) of this section does not include the basic filing fee, 
search fee, examination fee, at least one claim, or the inventor's oath 
or declaration, and the applicant has not provided a correspondence 
address (Sec. 1.33(a)), the applicant has three months from the filing 
date of the application within which to file a claim or claims, pay the 
basic filing fee, search fee, and examination fee, and pay the surcharge 
required by Sec. 1.16(f), to avoid abandonment.
    (3) The inventor's oath or declaration in an application under 
Sec. 1.53(b) must also be filed within the period specified in paragraph 
(f)(1) or (f)(2) of this section, except that the filing of the 
inventor's oath or declaration may be postponed until the application is 
otherwise in condition for allowance under the conditions specified in 
paragraphs (f)(3)(i) and (f)(3)(ii) of this section.
    (i) The application must be an original (non-reissue) application 
that contains an application data sheet in accordance with Sec. 1.76 
identifying:
    (A) Each inventor by his or her legal name;
    (B) A mailing address where the inventor customarily receives mail, 
and residence, if an inventor lives at a location which is different 
from where the inventor customarily receives mail, for each inventor.
    (ii) The applicant must file each required oath or declaration in 
compliance with Sec. 1.63, or substitute statement in compliance with 
Sec. 1.64, no later than the date on which the issue fee for the patent 
is paid. If the applicant is notified in a notice of allowability that 
an oath or declaration in compliance with Sec. 1.63, or substitute 
statement in compliance with Sec. 1.64, executed by or with respect to 
each named inventor has not been filed, the applicant must file each 
required oath or declaration in compliance with Sec. 1.63, or substitute 
statement in compliance with Sec. 1.64, no later than the date on which 
the issue fee is paid to avoid abandonment. This time period is not 
extendable under Sec. 1.136 (see Sec. 1.136(c)). The Office may dispense 
with the notice provided for in paragraph (f)(1) of this section if each 
required oath or declaration in compliance with Sec. 1.63, or substitute 
statement in compliance with Sec. 1.64, has been filed before the 
application is in condition for allowance.
    (4) If the excess claims fees required by Sec. 1.16(h) and (i) and 
multiple dependent claim fee required by Sec. 1.16(j) are not paid on 
filing or on later presentation of the claims for which the excess 
claims or multiple dependent claim fees are due, the fees required by 
Sec. 1.16(h), (i), and (j) must be paid or the claims canceled by 
amendment prior to the expiration of the time period set for reply by 
the Office in any notice of fee deficiency. If the application size fee 
required by Sec. 1.16(s) (if any) is not paid on filing or on later 
presentation of the amendment necessitating a fee or additional fee 
under Sec. 1.16(s), the fee required by Sec. 1.16(s) must be paid prior 
to the expiration of the time period set for reply by the Office in any 
notice of fee deficiency in order to avoid abandonment.
    (5) This paragraph applies to continuation or divisional 
applications under paragraphs (b) or (d) of this section and to 
continuation-in-part applications under paragraph (b) of this section. 
See Sec. 1.63(d) concerning the submission of a copy of the inventor's 
oath or declaration from the prior application for a continuing 
application under paragraph (b) of this section.
    (6) If applicant does not pay the basic filing fee during the 
pendency of the application, the Office may dispose of the application.
    (g) Completion of application subsequent to filing--Provisional 
application. (1) If a provisional application which has been accorded a 
filing date pursuant to paragraph (c) of this section does not include 
the cover sheet required by Sec. 1.51(c)(1) or the basic filing fee 
(Sec. 1.16(d)), and applicant has provided a correspondence address 
(Sec. 1.33(a)), applicant will be notified and given a period of time 
within which to pay the basic filing fee, file a cover sheet 
(Sec. 1.51(c)(1)), and pay the surcharge required by Sec. 1.16(g) to 
avoid abandonment.
    (2) If a provisional application which has been accorded a filing 
date pursuant to paragraph (c) of this section does not include the 
cover sheet required by Sec. 1.51(c)(1) or the basic filing

[[Page 62]]

fee (Sec. 1.16(d)), and applicant has not provided a correspondence 
address (Sec. 1.33(a)), applicant has two months from the filing date of 
the application within which to pay the basic filing fee, file a cover 
sheet (Sec. 1.51(c)(1)), and pay the surcharge required by Sec. 1.16(g) 
to avoid abandonment.
    (3) If the application size fee required by Sec. 1.16(s) (if any) is 
not paid on filing, the fee required by Sec. 1.16(s) must be paid prior 
to the expiration of the time period set for reply by the Office in any 
notice of fee deficiency in order to avoid abandonment.
    (4) If applicant does not pay the basic filing fee during the 
pendency of the application, the Office may dispose of the application.
    (h) Subsequent treatment of application--Nonprovisional (including 
continued prosecution) application. An application for a patent filed 
under paragraphs (b) or (d) of this section will not be placed on the 
files for examination until all its required parts, complying with the 
rules relating thereto, are received, except that the inventor's oath or 
declaration may be filed when the application is otherwise in condition 
for allowance pursuant to paragraph (f)(3) of this section and minor 
informalities may be waived subject to subsequent correction whenever 
required.
    (i) Subsequent treatment of application--Provisional application. A 
provisional application for a patent filed under paragraph (c) of this 
section will not be placed on the files for examination and will become 
abandoned no later than twelve months after its filing date pursuant to 
35 U.S.C. 111(b)(1).

Sec. 1.55  Claim for foreign priority.

    (a) In general. An applicant in a nonprovisional application may 
claim priority to one or more prior foreign applications under the 
conditions specified in 35 U.S.C. 119(a) through (d) and (f), 172, 
365(a) and (b), and 386(a) and (b) and this section.
    (b) Time for filing subsequent application. The nonprovisional 
application must be:
    (1) Filed not later than twelve months (six months in the case of a 
design application) after the date on which the foreign application was 
filed, subject to paragraph (c) of this section (a subsequent 
application); or
    (2) Entitled to claim the benefit under 35 U.S.C. 120, 121, 365(c), 
or 386(c) of a subsequent application that was filed within the period 
set forth in paragraph (b)(1) of this section.
    (c) Delayed filing of subsequent application. If the subsequent 
application has a filing date which is after the expiration of the 
period set forth in paragraph (b)(1) of this section, but within two 
months from the expiration of the period set forth in paragraph (b)(1) 
of this section, the right of priority in the subsequent application may 
be restored under PCT Rule 26bis.3 for an international application, or 
upon petition pursuant to this paragraph, if the delay in filing the 
subsequent application within the period set forth in paragraph (b)(1) 
of this section was unintentional. A petition to restore the right of 
priority under this paragraph filed on or after May 13, 2015, must be 
filed in the subsequent application, or in the earliest nonprovisional 
application claiming benefit under 35 U.S.C.

[[Page 63]]

120, 121, 365(c), or 386(c) to the subsequent application, if such 
subsequent application is not a nonprovisional application. Any petition 
to restore the right of priority under this paragraph must include:
    (1) The priority claim under 35 U.S.C. 119(a) through (d) or (f), 
365(a) or (b), or 386(a) or (b) in an application data sheet 
(Sec. 1.76(b)(6)), identifying the foreign application to which priority 
is claimed, by specifying the application number, country (or 
intellectual property authority), day, month, and year of its filing, 
unless previously submitted;
    (2) The petition fee as set forth in Sec. 1.17(m); and
    (3) A statement that the delay in filing the subsequent application 
within the period set forth in paragraph (b)(1) of this section was 
unintentional. The Director may require additional information where 
there is a question whether the delay was unintentional.
    (d) Time for filing priority claim--(1) Application under 35 U.S.C. 
111(a). The claim for priority must be filed within the later of four 
months from the actual filing date of the application or sixteen months 
from the filing date of the prior foreign application in an original 
application filed under 35 U.S.C. 111(a), except as provided in 
paragraph (e) of this section. The claim for priority must be presented 
in an application data sheet (Sec. 1.76(b)(6)) and must identify the 
foreign application to which priority is claimed by specifying the 
application number, country (or intellectual property authority), day, 
month, and year of its filing. The time periods in this paragraph do not 
apply if the later-filed application is:
    (i) An application for a design patent; or
    (ii) An application filed under 35 U.S.C. 111(a) before November 29, 
2000.
    (2) Application under 35 U.S.C. 371. The claim for priority must be 
made within the time limit set forth in the PCT and the Regulations 
under the PCT in an international application entering the national 
stage under 35 U.S.C. 371, except as provided in paragraph (e) of this 
section.
    (e) Delayed priority claim. Unless such claim is accepted in 
accordance with the provisions of this paragraph, any claim for priority 
under 35 U.S.C. 119(a) through (d) or (f), 365(a) or (b), or 386(a) or 
386(b) not presented in the manner required by paragraph (d) or (m) of 
this section during pendency and within the time period provided by 
paragraph (d) of this section (if applicable) is considered to have been 
waived. If a claim for priority is considered to have been waived under 
this section, the claim may be accepted if the priority claim was 
unintentionally delayed. A petition to accept a delayed claim for 
priority under 35 U.S.C. 119(a) through (d) or (f), 365(a) or (b), or 
386(a) or 386(b) must be accompanied by:
    (1) The priority claim under 35 U.S.C. 119(a) through (d) or (f), 
365(a) or (b), or 386(a) or 386(b) in an application data sheet 
(Sec. 1.76(b)(6)), identifying the foreign application to which priority 
is claimed, by specifying the application number, country (or 
intellectual property authority), day, month, and year of its filing, 
unless previously submitted;
    (2) A certified copy of the foreign application, unless previously 
submitted or an exception in paragraph (h), (i), or (j) of this section 
applies;
    (3) The petition fee as set forth in Sec. 1.17(m); and
    (4) A statement that the entire delay between the date the priority 
claim was due under this section and the date the priority claim was 
filed was unintentional. The Director may require additional information 
where there is a question whether the delay was unintentional.
    (f) Time for filing certified copy of foreign application--(1) 
Application under 35 U.S.C. 111(a). A certified copy of the foreign 
application must be filed within the later of four months from the 
actual filing date of the application, or sixteen months from the filing 
date of the prior foreign application, in an original application under 
35 U.S.C. 111(a) filed on or after March 16, 2013, except as provided in 
paragraphs (h), (i), and (j) of this section. The time period in this 
paragraph does not apply in a design application.
    (2) Application under 35 U.S.C. 371. A certified copy of the foreign 
application must be filed within the time

[[Page 64]]

limit set forth in the PCT and the Regulations under the PCT in an 
international application entering the national stage under 35 U.S.C. 
371. If a certified copy of the foreign application is not filed during 
the international stage in an international application in which the 
national stage commenced on or after December 18, 2013, a certified copy 
of the foreign application must be filed within the later of four months 
from the date on which the national stage commenced under 35 U.S.C. 
371(b) or (f) (Sec. 1.491(a)), four months from the date of the initial 
submission under 35 U.S.C. 371 to enter the national stage, or sixteen 
months from the filing date of the prior foreign application, except as 
provided in paragraphs (h), (i), and (j) of this section.
    (3) If a certified copy of the foreign application is not filed 
within the time period specified paragraph (f)(1) of this section in an 
application under 35 U.S.C. 111(a) or within the period specified in 
paragraph (f)(2) of this section in an international application 
entering the national stage under 35 U.S.C. 371, and an exception in 
paragraph (h), (i), or (j) of this section is not applicable, the 
certified copy of the foreign application must be accompanied by a 
petition including a showing of good and sufficient cause for the delay 
and the petition fee set forth in Sec. 1.17(g).
    (g) Requirement for filing priority claim, certified copy of foreign 
application, and translation in any application. (1) The claim for 
priority and the certified copy of the foreign application specified in 
35 U.S.C. 119(b) or PCT Rule 17 must, in any event, be filed within the 
pendency of the application, unless filed with a petition under 
paragraph (e) or (f) of this section, or with a petition accompanied by 
the fee set forth in Sec. 1.17(g) which includes a showing of good and 
sufficient cause for the delay in filing the certified copy of the 
foreign application in a design application. If the claim for priority 
or the certified copy of the foreign application is filed after the date 
the issue fee is paid, the patent will not include the priority claim 
unless corrected by a certificate of correction under 35 U.S.C. 255 and 
Sec. 1.323.
    (2) The Office may require that the claim for priority and the 
certified copy of the foreign application be filed earlier than 
otherwise provided in this section:
    (i) When the application is involved in an interference (see 
Sec. 41.202 of this chapter) or derivation (see part 42 of this chapter) 
proceeding;
    (ii) When necessary to overcome the date of a reference relied upon 
by the examiner; or
    (iii) When deemed necessary by the examiner.
    (3) An English language translation of a non-English language 
foreign application is not required except:
    (i) When the application is involved in an interference (see 
Sec. 41.202 of this chapter) or derivation (see part 42 of this chapter) 
proceeding;
    (ii) When necessary to overcome the date of a reference relied upon 
by the examiner; or
    (iii) When specifically required by the examiner.
    (4) If an English language translation of a non-English language 
foreign application is required, it must be filed together with a 
statement that the translation of the certified copy is accurate.
    (h) Certified copy in another U.S. patent or application. The 
requirement in paragraphs (f) and (g) of this section for a certified 
copy of the foreign application will be considered satisfied in a 
reissue application if the patent for which reissue is sought satisfies 
the requirement of this section for a certified copy of the foreign 
application and such patent is identified as containing a certified copy 
of the foreign application. The requirement in paragraphs (f) and (g) of 
this section for a certified copy of the foreign application will also 
be considered satisfied in an application if a prior-filed 
nonprovisional application for which a benefit is claimed under 35 
U.S.C. 120, 121, 365(c), or 386(c) contains a certified copy of the 
foreign application and such prior-filed nonprovisional application is 
identified as containing a certified copy of the foreign application.
    (i) Foreign intellectual property office participating in a priority 
document exchange agreement. The requirement in paragraphs (f) and (g) 
of this section for a certified copy of the foreign application to be 
filed within the time limit

[[Page 65]]

set forth therein will be considered satisfied if:
    (1) The foreign application was filed in a foreign intellectual 
property office participating with the Office in a bilateral or 
multilateral priority document exchange agreement (participating foreign 
intellectual property office), or a copy of the foreign application was 
filed in an application subsequently filed in a participating foreign 
intellectual property office that permits the Office to obtain such a 
copy;
    (2) The claim for priority is presented in an application data sheet 
(Sec. 1.76(b)(6)), identifying the foreign application for which 
priority is claimed, by specifying the application number, country (or 
intellectual property authority), day, month, and year of its filing, 
and the applicant provides the information necessary for the 
participating foreign intellectual property office to provide the Office 
with access to the foreign application;
    (3) The copy of the foreign application is received by the Office 
from the participating foreign intellectual property office, or a 
certified copy of the foreign application is filed, within the period 
specified in paragraph (g)(1) of this section; and
    (4) The applicant files in a separate document a request that the 
Office obtain a copy of the foreign application from a participating 
intellectual property office that permits the Office to obtain such a 
copy where, although the foreign application was not filed in a 
participating foreign intellectual property office, a copy of the 
foreign application was filed in an application subsequently filed in a 
participating foreign intellectual property office that permits the 
Office to obtain such a copy. The request must identify the 
participating intellectual property office and the subsequent 
application by the application number, day, month, and year of its 
filing in which a copy of the foreign application was filed. The request 
must be filed within the later of sixteen months from the filing date of 
the prior foreign application, four months from the actual filing date 
of an application under 35 U.S.C. 111(a), four months from the date on 
which the national stage commenced under 35 U.S.C. 371(b) or (f) 
(Sec. 1.491(a)), or four months from the date of the initial submission 
under 35 U.S.C. 371 to enter the national stage, or the request must be 
accompanied by a petition under paragraph (e) or (f) of this section.
    (j) Interim copy. The requirement in paragraph (f) of this section 
for a certified copy of the foreign application to be filed within the 
time limit set forth therein will be considered satisfied if:
    (1) A copy of the original foreign application clearly labeled as 
``Interim Copy,'' including the specification, and any drawings or 
claims upon which it is based, is filed in the Office together with a 
separate cover sheet identifying the foreign application by specifying 
the application number, country (or intellectual property authority), 
day, month, and year of its filing, and stating that the copy filed in 
the Office is a true copy of the original application as filed in the 
foreign country (or intellectual property authority);
    (2) The copy of the foreign application and separate cover sheet are 
filed within the later of sixteen months from the filing date of the 
prior foreign application, four months from the actual filing date of an 
application under 35 U.S.C. 111(a), four months from the date on which 
the national stage commenced under 35 U.S.C. 371(b) or (f) 
(Sec. 1.491(a)), four months from the date of the initial submission 
under 35 U.S.C. 371 to enter the national stage, or with a petition 
under paragraph (e) or (f) of this section; and
    (3) A certified copy of the foreign application is filed within the 
period specified in paragraph (g)(1) of this section.
    (k) Requirements for certain applications filed on or after March 
16, 2013. If a nonprovisional application filed on or after March 16, 
2013, other than a nonprovisional international design application, 
claims priority to a foreign application filed prior to March 16, 2013, 
and also contains, or contained at any time, a claim to a claimed 
invention that has an effective filing date as defined in Sec. 1.109 
that is on or after March 16, 2013, the applicant must provide a 
statement to that effect within the later of four months from the actual 
filing date of the nonprovisional application, four months from the date 
of entry into the national stage as set

[[Page 66]]

forth in Sec. 1.491 in an international application, sixteen months from 
the filing date of the prior foreign application, or the date that a 
first claim to a claimed invention that has an effective filing date on 
or after March 16, 2013, is presented in the nonprovisional application. 
An applicant is not required to provide such a statement if the 
applicant reasonably believes on the basis of information already known 
to the individuals designated in Sec. 1.56(c) that the nonprovisional 
application does not, and did not at any time, contain a claim to a 
claimed invention that has an effective filing date on or after March 
16, 2013.
    (l) Inventor's certificates. An applicant in a nonprovisional 
application may under certain circumstances claim priority on the basis 
of one or more applications for an inventor's certificate in a country 
granting both inventor's certificates and patents. To claim the right of 
priority on the basis of an application for an inventor's certificate in 
such a country under 35 U.S.C. 119(d), the applicant, when submitting a 
claim for such right as specified in this section, must include an 
affidavit or declaration. The affidavit or declaration must include a 
specific statement that, upon an investigation, he or she is satisfied 
that to the best of his or her knowledge, the applicant, when filing the 
application for the inventor's certificate, had the option to file an 
application for either a patent or an inventor's certificate as to the 
subject matter of the identified claim or claims forming the basis for 
the claim of priority.
    (m) Time for filing priority claim and certified copy of foreign 
application in an international design application designating the 
United States. In an international design application designating the 
United States, the claim for priority may be made in accordance with the 
Hague Agreement and the Hague Agreement Regulations. In a nonprovisional 
international design application, the priority claim, unless made in 
accordance with the Hague Agreement and the Hague Agreement Regulations, 
must be presented in an application data sheet (Sec. 1.76(b)(6)), 
identifying the foreign application for which priority is claimed, by 
specifying the application number, country (or intellectual property 
authority), day, month, and year of its filing. In a nonprovisional 
international design application, the priority claim and certified copy 
must be furnished in accordance with the time period and other 
conditions set forth in paragraph (g) of this section.
    (n) Applications filed before September 16, 2012. Notwithstanding 
the requirement in paragraphs (d)(1), (e)(1), and (i)(2) of this section 
that any priority claim be presented in an application data sheet 
(Sec. 1.76), this requirement in paragraphs (d)(1), (e)(1), and (i)(2) 
of this section will be satisfied by the presentation of such priority 
claim in the oath or declaration under Sec. 1.63 in a nonprovisional 
application filed under 35 U.S.C. 111(a) before September 16, 2012, or 
resulting from an international application filed under 35 U.S.C. 363 
before September 16, 2012. The provisions of this paragraph do not apply 
to any priority claim submitted for a petition under paragraph (c) of 
this section to restore the right of priority to a foreign application.
    (o) Priority under 35 U.S.C. 386(a) or (b). The right of priority 
under 35 U.S.C. 386(a) or (b) with respect to an international design 
application is applicable only to nonprovisional applications, 
international applications, and international design applications filed 
on or after May 13, 2015, and patents issuing thereon.
    (p) Time periods in this section. The time periods set forth in this 
section are not extendable, but are subject to 35 U.S.C. 21(b) (and 
Sec. 1.7(a)), PCT Rule 80.5, and Hague Agreement Rule 4(4).

[80 FR 17956, Apr. 2, 2015]



Sec. 1.56  Duty to disclose information material to patentability.

    (a) A patent by its very nature is affected with a public interest. 
The public interest is best served, and the most effective patent 
examination occurs when, at the time an application is being examined, 
the Office is aware of and evaluates the teachings of all information 
material to patentability. Each individual associated with the filing 
and prosecution of a patent application has a duty of candor and good 
faith in dealing with the Office, which includes a duty to disclose to 
the Office

[[Page 67]]

all information known to that individual to be material to patentability 
as defined in this section. The duty to disclose information exists with 
respect to each pending claim until the claim is cancelled or withdrawn 
from consideration, or the application becomes abandoned. Information 
material to the patentability of a claim that is cancelled or withdrawn 
from consideration need not be submitted if the information is not 
material to the patentability of any claim remaining under consideration 
in the application. There is no duty to submit information which is not 
material to the patentability of any existing claim. The duty to 
disclose all information known to be material to patentability is deemed 
to be satisfied if all information known to be material to patentability 
of any claim issued in a patent was cited by the Office or submitted to 
the Office in the manner prescribed by Secs. 1.97(b)-(d) and 1.98. 
However, no patent will be granted on an application in connection with 
which fraud on the Office was practiced or attempted or the duty of 
disclosure was violated through bad faith or intentional misconduct. The 
Office encourages applicants to carefully examine:
    (1) Prior art cited in search reports of a foreign patent office in 
a counterpart application, and
    (2) The closest information over which individuals associated with 
the filing or prosecution of a patent application believe any pending 
claim patentably defines, to make sure that any material information 
contained therein is disclosed to the Office.
    (b) Under this section, information is material to patentability 
when it is not cumulative to information already of record or being made 
of record in the application, and
    (1) It establishes, by itself or in combination with other 
information, a prima facie case of unpatentability of a claim; or
    (2) It refutes, or is inconsistent with, a position the applicant 
takes in:
    (i) Opposing an argument of unpatentability relied on by the Office, 
or
    (ii) Asserting an argument of patentability.

A prima facie case of unpatentability is established when the 
information compels a conclusion that a claim is unpatentable under the 
preponderance of evidence, burden-of-proof standard, giving each term in 
the claim its broadest reasonable construction consistent with the 
specification, and before any consideration is given to evidence which 
may be submitted in an attempt to establish a contrary conclusion of 
patentability.
    (c) Individuals associated with the filing or prosecution of a 
patent application within the meaning of this section are:
    (1) Each inventor named in the application;
    (2) Each attorney or agent who prepares or prosecutes the 
application; and
    (3) Every other person who is substantively involved in the 
preparation or prosecution of the application and who is associated with 
the inventor, the applicant, an assignee, or anyone to whom there is an 
obligation to assign the application.
    (d) Individuals other than the attorney, agent or inventor may 
comply with this section by disclosing information to the attorney, 
agent, or inventor.
    (e) In any continuation-in-part application, the duty under this 
section includes the duty to disclose to the Office all information 
known to the person to be material to patentability, as defined in 
paragraph (b) of this section, which became available between the filing 
date of the prior application and the national or PCT international 
filing date of the continuation-in-part application.

Sec. 1.57  Incorporation by reference.

    (a) Subject to the conditions and requirements of this paragraph, a 
reference made in the English language in an application data sheet in 
accordance with Sec. 1.76 upon the filing of an application under 35 
U.S.C. 111(a) to a previously filed application, indicating that the 
specification and any drawings of the application under 35 U.S.C. 111(a) 
are replaced by the reference to

[[Page 68]]

the previously filed application, and specifying the previously filed 
application by application number, filing date, and the intellectual 
property authority or country in which the previously filed application 
was filed, shall constitute the specification and any drawings of the 
application under 35 U.S.C. 111(a) for purposes of a filing date under 
Sec. 1.53(b).
    (1) If the applicant has provided a correspondence address 
(Sec. 1.33(a)), the applicant will be notified and given a period of 
time within which to file a copy of the specification and drawings from 
the previously filed application, an English language translation of the 
previously filed application, and the fee required by Sec. 1.17(i) if it 
is in a language other than English, and pay the surcharge required by 
Sec. 1.16(f), to avoid abandonment. Such a notice may be combined with a 
notice under Sec. 1.53(f).
    (2) If the applicant has not provided a correspondence address 
(Sec. 1.33(a)), the applicant has three months from the filing date of 
the application to file a copy of the specification and drawings from 
the previously filed application, an English language translation of the 
previously filed application, and the fee required by Sec. 1.17(i) if it 
is in a language other than English, and pay the surcharge required by 
Sec. 1.16(f), to avoid abandonment.
    (3) An application abandoned under paragraph (a)(1) or (a)(2) of 
this section shall be treated as having never been filed, unless:
    (i) The application is revived under Sec. 1.137; and
    (ii) A copy of the specification and any drawings of the previously 
filed application are filed in the Office.
    (4) A certified copy of the previously filed application must be 
filed in the Office, unless the previously filed application is an 
application filed under 35 U.S.C. 111 or 363, or the previously filed 
application is a foreign priority application and the conditions set 
forth in Sec. 1.55(i) are satisfied with respect to such foreign 
priority application. The certified copy of the previously filed 
application, if required by this paragraph, must be filed within the 
later of four months from the filing date of the application or sixteen 
months from the filing date of the previously filed application, or be 
accompanied by a petition including a showing of good and sufficient 
cause for the delay and the petition fee set forth in Sec. 1.17(g).
    (b) Subject to the conditions and requirements of this paragraph, if 
all or a portion of the specification or drawing(s) is inadvertently 
omitted from an application, but the application contains a claim under 
Sec. 1.55 for priority of a prior-filed foreign application or a claim 
under Sec. 1.78 for the benefit of a prior-filed provisional, 
nonprovisional, international application, or international design 
application, that was present on the filing date of the application, and 
the inadvertently omitted portion of the specification or drawing(s) is 
completely contained in the prior-filed application, the claim under 
Sec. 1.55 or 1.78 shall also be considered an incorporation by reference 
of the prior-filed application as to the inadvertently omitted portion 
of the specification or drawing(s).
    (1) The application must be amended to include the inadvertently 
omitted portion of the specification or drawing(s) within any time 
period set by the Office, but in no case later than the close of 
prosecution as defined by Sec. 1.114(b), or abandonment of the 
application, whichever occurs earlier. The applicant is also required 
to:
    (i) Supply a copy of the prior-filed application, except where the 
prior-filed application is an application filed under 35 U.S.C. 111;
    (ii) Supply an English language translation of any prior-filed 
application that is in a language other than English; and
    (iii) Identify where the inadvertently omitted portion of the 
specification or drawings can be found in the prior-filed application.
    (2) Any amendment to an international application pursuant to 
paragraph (b)(1) of this section shall be effective only as to the 
United States, and shall have no effect on the international filing date 
of the application. In addition, no request under this section to add 
the inadvertently omitted portion of the specification or drawings in an 
international application designating the United States will be acted 
upon by the Office prior to the entry

and commencement of the national stage (Sec. 1.491) or the filing of an 
application under 35 U.S.C. 111(a) which claims benefit of the 
international application. Any omitted portion of the international 
application which applicant desires to be effective as to all designated 
States, subject to PCT Rule 20.8(b), must be submitted in accordance 
with PCT Rule 20.
    (3) If an application is not otherwise entitled to a filing date 
under Sec. 1.53(b), the amendment must be by way of a petition pursuant 
to Sec. 1.53(e) accompanied by the fee set forth in Sec. 1.17(f).
    (4) Any amendment to an international design application pursuant to 
paragraph (b)(1) of this section shall be effective only as to the 
United States and shall have no effect on the filing date of the 
application. In addition, no request under this section to add the 
inadvertently omitted portion of the specification or drawings in an 
international design application will be acted upon by the Office prior 
to the international design application becoming a nonprovisional 
application.
    (c) Except as provided in paragraph (a) or (b) of this section, an 
incorporation by reference must be set forth in the specification and 
must:
    (1) Express a clear intent to incorporate by reference by using the 
root words ``incorporat(e)'' and ``reference'' (e.g., ``incorporate by 
reference''); and
    (2) Clearly identify the referenced patent, application, or 
publication.
    (d) ``Essential material'' may be incorporated by reference, but 
only by way of an incorporation by reference to a U.S. patent or U.S. 
patent application publication, which patent or patent application 
publication does not itself incorporate such essential material by 
reference. ``Essential material'' is material that is necessary to:
    (1) Provide a written description of the claimed invention, and of 
the manner and process of making and using it, in such full, clear, 
concise, and exact terms as to enable any person skilled in the art to 
which it pertains, or with which it is most nearly connected, to make 
and use the same, and set forth the best mode contemplated by the 
inventor of carrying out the invention as required by 35 U.S.C. 112(a);
    (2) Describe the claimed invention in terms that particularly point 
out and distinctly claim the invention as required by 35 U.S.C. 112(b); 
or
    (3) Describe the structure, material, or acts that correspond to a 
claimed means or step for performing a specified function as required by 
35 U.S.C. 112(f).
    (e) Other material (``Nonessential material'') may be incorporated 
by reference to U.S. patents, U.S. patent application publications, 
foreign patents, foreign published applications, prior and concurrently 
filed commonly owned U.S. applications, or non-patent publications. An 
incorporation by reference by hyperlink or other form of browser 
executable code is not permitted.
    (f) The examiner may require the applicant to supply a copy of the 
material incorporated by reference. If the Office requires the applicant 
to supply a copy of material incorporated by reference, the material 
must be accompanied by a statement that the copy supplied consists of 
the same material incorporated by reference in the referencing 
application.
    (g) Any insertion of material incorporated by reference into the 
specification or drawings of an application must be by way of an 
amendment to the specification or drawings. Such an amendment must be 
accompanied by a statement that the material being inserted is the 
material previously incorporated by reference and that the amendment 
contains no new matter.
    (h) An incorporation of material by reference that does not comply 
with paragraphs (c), (d), or (e) of this section is not effective to 
incorporate such material unless corrected within any time period set by 
the Office, but in no case later than the close of prosecution as 
defined by Sec. 1.114(b), or abandonment of the application, whichever 
occurs earlier. In addition:
    (1) A correction to comply with paragraph (c)(1) of this section is 
permitted only if the application as filed clearly conveys an intent to 
incorporate the material by reference. A mere reference to material does 
not convey an intent to incorporate the material by reference.

[[Page 70]]

    (2) A correction to comply with paragraph (c)(2) of this section is 
only permitted for material that was sufficiently described to uniquely 
identify the document.
    (i) An application transmittal letter limited to the transmittal of 
a copy of the specification and drawings from a previously filed 
application submitted under paragraph (a) or (b) of this section may be 
signed by a juristic applicant or patent owner.

Sec. 1.58  Chemical and mathematical formulae and tables.

    (a) The specification, including the claims, may contain chemical 
and mathematical formulae, but shall not contain drawings or flow 
diagrams. The description portion of the specification may contain 
tables, but the same tables should not be included in both the drawings 
and description portion of the specification. Claims may contain tables 
either if necessary to conform to 35 U.S.C. 112 or if otherwise found to 
be desirable.
    (b) Tables that are submitted in electronic form (Secs. 1.96(c) and 
1.821(c)) must maintain the spatial relationships (e.g., alignment of 
columns and rows) of the table elements when displayed so as to visually 
preserve the relational information they convey. Chemical and 
mathematical formulae must be encoded to maintain the proper positioning 
of their characters when displayed in order to preserve their intended 
meaning.
    (c) Chemical and mathematical formulae and tables must be presented 
in compliance with Sec. 1.52(a) and (b), except that chemical and 
mathematical formulae or tables may be placed in a landscape orientation 
if they cannot be presented satisfactorily in a portrait orientation. 
Typewritten characters used in such formulae and tables must be chosen 
from a block (nonscript) type font or lettering style having capital 
letters which should be at least 0.422 cm. (0.166 inch) high (e.g., 
preferably Arial, Times Roman, or Courier with a font size of 12), but 
may be no smaller than 0.21 cm. (0.08 inch) high (e.g., a font size of 
6). A space at least 0.64 cm. (1/4 inch) high should be provided between 
complex formulae and tables and the text. Tables should have the lines 
and columns of data closely spaced to conserve space, consistent with a 
high degree of legibility.

Sec. 1.59  Expungement of information or copy of papers in application file.

    (a) (1) Information in an application will not be expunged, except 
as provided in paragraph (b) of this section or Sec. 41.7(a) or 
Sec. 42.7(a) of this title.
    (2) Information forming part of the original disclosure (i.e., 
written specification including the claims, drawings, and any 
preliminary amendment present on the filing date of the application) 
will not be expunged from the application file.
    (b) An applicant may request that the Office expunge information, 
other than what is excluded by paragraph (a)(2) of this section, by 
filing a petition under this paragraph. Any petition to expunge 
information from an application must include the fee set forth in 
Sec. 1.17(g) and establish to the satisfaction of the Director that the 
expungement of the information is appropriate in which case a notice 
granting the petition for expungement will be provided.
    (c) Upon request by an applicant and payment of the fee specified in 
Sec. 1.19(b), the Office will furnish copies of an application, unless 
the application has been disposed of (see Secs. 1.53(e), (f) and (g)). 
The Office cannot provide or certify copies of an application that has 
been disposed of.

Secs. 1.60-1.62  [Reserved]

                           Oath or Declaration



Sec. 1.63  Inventor's oath or declaration.

    (a) The inventor, or each individual who is a joint inventor of a 
claimed invention, in an application for patent must execute an oath or 
declaration directed to the application, except as provided for in 
Sec. 1.64. An oath or declaration under this section must:

[[Page 71]]

    (1) Identify the inventor or joint inventor executing the oath or 
declaration by his or her legal name;
    (2) Identify the application to which it is directed;
    (3) Include a statement that the person executing the oath or 
declaration believes the named inventor or joint inventor to be the 
original inventor or an original joint inventor of a claimed invention 
in the application for which the oath or declaration is being submitted; 
and
    (4) State that the application was made or was authorized to be made 
by the person executing the oath or declaration.
    (b) Unless the following information is supplied in an application 
data sheet in accordance with Sec. 1.76, the oath or declaration must 
also identify:
    (1) Each inventor by his or her legal name; and
    (2) A mailing address where the inventor customarily receives mail, 
and residence, if an inventor lives at a location which is different 
from where the inventor customarily receives mail, for each inventor.
    (c) A person may not execute an oath or declaration for an 
application unless that person has reviewed and understands the contents 
of the application, including the claims, and is aware of the duty to 
disclose to the Office all information known to the person to be 
material to patentability as defined in Sec. 1.56. There is no minimum 
age for a person to be qualified to execute an oath or declaration, but 
the person must be competent to execute, i.e., understand, the document 
that the person is executing.
    (d)(1) A newly executed oath or declaration under Sec. 1.63, or 
substitute statement under Sec. 1.64, is not required under 
Secs. 1.51(b)(2) and 1.53(f), or under Secs. 1.497 and 1.1021(d), for an 
inventor in a continuing application that claims the benefit under 35 
U.S.C. 120, 121, 365(c), or 386(c) in compliance with Sec. 1.78 of an 
earlier-filed application, provided that an oath or declaration in 
compliance with this section, or substitute statement under Sec. 1.64, 
was executed by or with respect to such inventor and was filed in the 
earlier-filed application, and a copy of such oath, declaration, or 
substitute statement showing the signature or an indication thereon that 
it was executed, is submitted in the continuing application.
    (2) The inventorship of a continuing application filed under 35 
U.S.C. 111(a) is the inventor or joint inventors specified in the 
application data sheet filed before or concurrently with the copy of the 
inventor's oath or declaration from the earlier-filed application. If an 
application data sheet is not filed before or concurrently with the copy 
of the inventor's oath or declaration from the earlier-filed 
application, the inventorship is the inventorship set forth in the copy 
of the inventor's oath or declaration from the earlier-filed 
application, unless it is accompanied by a statement signed pursuant to 
Sec. 1.33(b) stating the name of each inventor in the continuing 
application.
    (3) Any new joint inventor named in the continuing application must 
provide an oath or declaration in compliance with this section, except 
as provided for in Sec. 1.64.
    (e)(1) An assignment may also serve as an oath or declaration 
required by this section if the assignment as executed:
    (i) Includes the information and statements required under 
paragraphs (a) and (b) of this section; and
    (ii) A copy of the assignment is recorded as provided for in part 3 
of this chapter.
    (2) Any reference to an oath or declaration under this section 
includes an assignment as provided for in this paragraph.
    (f) With respect to an application naming only one inventor, any 
reference to the inventor's oath or declaration in this chapter includes 
a substitute statement executed under Sec. 1.64. With respect to an 
application naming more than one inventor, any reference to the 
inventor's oath or declaration in this chapter means the oaths, 
declarations, or substitute statements that have been collectively 
executed by or with respect to all of the joint inventors, unless 
otherwise clear from the context.
    (g) An oath or declaration under this section, including the 
statement provided for in paragraph (e) of this section, must be 
executed (i.e., signed) in accordance either with Sec. 1.66 or with an

[[Page 72]]

acknowledgment that any willful false statement made in such declaration 
or statement is punishable under 18 U.S.C. 1001 by fine or imprisonment 
of not more than five (5) years, or both.
    (h) An oath or declaration filed at any time pursuant to 35 U.S.C. 
115(h)(1) will be placed in the file record of the application or 
patent, but may not necessarily be reviewed by the Office. Any request 
for correction of the named inventorship must comply with Sec. 1.48 in 
an application and Sec. 1.324 in a patent.

Sec. 1.64  Substitute statement in lieu of an oath or declaration.

    (a) An applicant under Sec. 1.43, 1.45 or 1.46 may execute a 
substitute statement in lieu of an oath or declaration under Sec. 1.63 
if the inventor is deceased, is under a legal incapacity, has refused to 
execute the oath or declaration under Sec. 1.63, or cannot be found or 
reached after diligent effort.
    (b) A substitute statement under this section must:
    (1) Comply with the requirements of Sec. 1.63(a), identifying the 
inventor or joint inventor with respect to whom a substitute statement 
in lieu of an oath or declaration is executed, and stating upon 
information and belief the facts which such inventor is required to 
state;
    (2) Identify the person executing the substitute statement and the 
relationship of such person to the inventor or joint inventor with 
respect to whom the substitute statement is executed, and unless such 
information is supplied in an application data sheet in accordance with 
Sec. 1.76, the residence and mailing address of the person signing the 
substitute statement;
    (3) Identify the circumstances permitting the person to execute the 
substitute statement in lieu of an oath or declaration under Sec. 1.63, 
namely whether the inventor is deceased, is under a legal incapacity, 
cannot be found or reached after a diligent effort was made, or has 
refused to execute the oath or declaration under Sec. 1.63; and
    (4) Unless the following information is supplied in an application 
data sheet in accordance with Sec. 1.76, also identify:
    (i) Each inventor by his or her legal name; and
    (ii) The last known mailing address where the inventor customarily 
receives mail, and last known residence, if an inventor lives at a 
location which is different from where the inventor customarily receives 
mail, for each inventor who is not deceased or under a legal incapacity.
    (c) A person may not execute a substitute statement provided for in 
this section for an application unless that person has reviewed and 
understands the contents of the application, including the claims, and 
is aware of the duty to disclose to the Office all information known to 
the person to be material to patentability as defined in Sec. 1.56.
    (d) Any reference to an inventor's oath or declaration includes a 
substitute statement provided for in this section.
    (e) A substitute statement under this section must contain an 
acknowledgment that any willful false statement made in such statement 
is punishable under section 1001 of title 18 by fine or imprisonment of 
not more than 5 years, or both.
    (f) A nonsigning inventor or legal representative may subsequently 
join in the application by submitting an oath or declaration under 
Sec. 1.63. The submission of an oath or declaration by a nonsigning 
inventor or legal representative in an application filed under 
Sec. 1.43, 1.45 or 1.46 will not permit the nonsigning inventor or legal 
representative to revoke or grant a power of attorney.

[77 FR 48819, Aug. 14, 2012]



Sec. 1.66  Statements under oath.

    An oath or affirmation may be made before any person within the 
United States authorized by law to administer oaths. An oath made in a 
foreign country may be made before any diplomatic or consular officer of 
the United States authorized to administer oaths, or before any officer 
having an official seal and authorized to administer oaths in the 
foreign country in which the applicant may be, whose authority shall be 
proved by a certificate of a diplomatic or consular officer of the 
United States, or by an apostille of an official designated by a foreign 
country which,

[[Page 73]]

by treaty or convention, accords like effect to apostilles of designated 
officials in the United States. The oath shall be attested in all cases 
in this and other countries, by the proper official seal of the officer 
before whom the oath or affirmation is made. Such oath or affirmation 
shall be valid as to execution if it complies with the laws of the State 
or country where made. When the person before whom the oath or 
affirmation is made in this country is not provided with a seal, his 
official character shall be established by competent evidence, as by a 
certificate from a clerk of a court of record or other proper officer 
having a seal.

meeting the requirements of Sec. 1.63, Sec. 1.64, or Sec. 1.162 to 
correct any deficiencies or inaccuracies present in an earlier-filed 
inventor's oath or declaration. Deficiencies or inaccuracies due to the 
failure to meet the requirements of Sec. 1.63(b) in an oath or 
declaration may be corrected with an application data sheet in 
accordance with Sec. 1.76, except that any correction of inventorship 
must be pursuant to Sec. 1.48.
    (b) A supplemental inventor's oath or declaration under this section 
must be executed by the person whose inventor's oath or declaration is 
being withdrawn, replaced, or otherwise corrected.
    (c) The Office will not require a person who has executed an oath or 
declaration in compliance with 35 U.S.C. 115 and Sec. 1.63 or 1.162 for 
an application to provide an additional inventor's oath or declaration 
for the application.
    (d) No new matter may be introduced into a nonprovisional 
application after its filing date even if an inventor's oath or 
declaration is filed to correct deficiencies or inaccuracies present in 
the earlier-filed inventor's oath or declaration.

Sec. 1.68  Declaration in lieu of oath.

    Any document to be filed in the Patent and Trademark Office and 
which is required by any law, rule, or other regulation to be under oath 
may be subscribed to by a written declaration. Such declaration may be 
used in lieu of the oath otherwise required, if, and only if, the 
declarant is on the same document, warned that willful false statements 
and the like are punishable by fine or imprisonment, or both (18 U.S.C. 
1001) and may jeopardize the validity of the application or any patent 
issuing thereon. The declarant must set forth in the body of the 
declaration that all statements made of the declarant's own knowledge 
are true and that all statements made on information and belief are 
believed to be true.

[49 FR 48452, Dec. 12, 1984]



Sec. 1.69  Foreign language oaths and declarations.

    (a) Whenever an individual making an oath or declaration cannot 
understand English, the oath or declaration must be in a language that 
such individual can understand and shall state that such individual 
understands the content of any documents to which the oath or 
declaration relates.
    (b) Unless the text of any oath or declaration in a language other 
than English is in a form provided by the Patent and Trademark Office or 
in accordance with PCT Rule 4.17(iv), it must be accompanied by an 
English translation together with a statement that the translation is 
accurate, except that in the case of an oath or declaration filed under 
Sec. 1.63, the translation may be filed in the Office no later than two 
months from the date applicant is notified to file the translation.

                              Specification

    Authority: Secs. 1.71 to 1.79 also issued under 35 U.S.C. 112.



Sec. 1.71  Detailed description and specification of the invention.

    (a) The specification must include a written description of the 
invention or

[[Page 74]]

discovery and of the manner and process of making and using the same, 
and is required to be in such full, clear, concise, and exact terms as 
to enable any person skilled in the art or science to which the 
invention or discovery appertains, or with which it is most nearly 
connected, to make and use the same.
    (b) The specification must set forth the precise invention for which 
a patent is solicited, in such manner as to distinguish it from other 
inventions and from what is old. It must describe completely a specific 
embodiment of the process, machine, manufacture, composition of matter 
or improvement invented, and must explain the mode of operation or 
principle whenever applicable. The best mode contemplated by the 
inventor of carrying out his invention must be set forth.
    (c) In the case of an improvement, the specification must 
particularly point out the part or parts of the process, machine, 
manufacture, or composition of matter to which the improvement relates, 
and the description should be confined to the specific improvement and 
to such parts as necessarily cooperate with it or as may be necessary to 
a complete understanding or description of it.
    (d) A copyright or mask work notice may be placed in a design or 
utility patent application adjacent to copyright and mask work material 
contained therein. The notice may appear at any appropriate portion of 
the patent application disclosure. For notices in drawings, see 
Sec. 1.84(s). The content of the notice must be limited to only those 
elements provided for by law. For example, `` 1983 
John Doe'' (17 U.S.C. 401) and `` *M* John Doe'' (17 U.S.C. 909) would 
be properly limited and, under current statutes, legally sufficient 
notices of copyright and mask work, respectively. Inclusion of a 
copyright or mask work notice will be permitted only if the 
authorization language set forth in paragraph (e) of this section is 
included at the beginning (preferably as the first paragraph) of the 
specification.
    (e) The authorization shall read as follows:

    A portion of the disclosure of this patent document contains 
material which is subject to (copyright or mask work) protection. The 
(copyright or mask work) owner has no objection to the facsimile 
reproduction by anyone of the patent document or the patent disclosure, 
as it appears in the Patent and Trademark Office patent file or records, 
but otherwise reserves all (copyright or mask work) rights whatsoever.

    (f) The specification must commence on a separate sheet. Each sheet 
including part of the specification may not include other parts of the 
application or other information. The claim(s), abstract and sequence 
listing (if any) should not be included on a sheet including any other 
part of the application.
    (g)(1) The specification may disclose or be amended to disclose the 
names of the parties to a joint research agreement as defined in 
Sec. 1.9(e).
    (2) An amendment under paragraph (g)(1) of this section must be 
accompanied by the processing fee set forth in Sec. 1.17(i) if not filed 
within one of the following time periods:
    (i) Within three months of the filing date of a national 
application;
    (ii) Within three months of the date of entry of the national stage 
as set forth in Sec. 1.491 in an international application;
    (iii) Before the mailing of a first Office action on the merits; or
    (iv) Before the mailing of a first Office action after the filing of 
a request for continued examination under Sec. 1.114.
    (3) If an amendment under paragraph (g)(1) of this section is filed 
after the date the issue fee is paid, the patent as issued may not 
necessarily include the names of the parties to the joint research 
agreement. If the patent as issued does not include the names of the 
parties to the joint research agreement, the patent must be corrected to 
include the names of the parties to the joint research agreement by a 
certificate of correction under 35 U.S.C. 255 and Sec. 1.323 for the 
amendment to be effective.

Sec. 1.72  Title and abstract.

    (a) The title of the invention may not exceed 500 characters in 
length and must be as short and specific as possible. Characters that 
cannot be captured and recorded in the Office's automated information 
systems may not be reflected in the Office's records in such systems or 
in documents created by the Office. Unless the title is supplied in an 
application data sheet (Sec. 1.76), the title of the invention should 
appear as a heading on the first page of the specification.
    (b) A brief abstract of the technical disclosure in the 
specification must commence on a separate sheet, preferably following 
the claims, under the heading ``Abstract'' or ``Abstract of the 
Disclosure.'' The sheet or sheets presenting the abstract may not 
include other parts of the application or other material. The abstract 
must be as concise as the disclosure permits, preferably not exceeding 
150 words in length. The purpose of the abstract is to enable the Office 
and the public generally to determine quickly from a cursory inspection 
the nature and gist of the technical disclosure.

Sec. 1.73  Summary of the invention.

    A brief summary of the invention indicating its nature and 
substance, which may include a statement of the object of the invention, 
should precede the detailed description. Such summary should, when set 
forth, be commensurate with the invention as claimed and any object 
recited should be that of the invention as claimed.



Sec. 1.74  Reference to drawings.

    When there are drawings, there shall be a brief description of the 
several views of the drawings and the detailed description of the 
invention shall refer to the different views by specifying the numbers 
of the figures and to the different parts by use of reference letters or 
numerals (preferably the latter).



Sec. 1.75  Claim(s).

    (a) The specification must conclude with a claim particularly 
pointing out and distinctly claiming the subject matter which the 
applicant regards as his invention or discovery.
    (b) More than one claim may be presented provided they differ 
substantially from each other and are not unduly multiplied.
    (c) One or more claims may be presented in dependent form, referring 
back to and further limiting another claim or claims in the same 
application. Any dependent claim which refers to more than one other 
claim (``multiple dependent claim'') shall refer to such other claims in 
the alternative only. A multiple dependent claim shall not serve as a 
basis for any other multiple dependent claim. For fee calculation 
purposes under Sec. 1.16, a multiple dependent claim will be considered 
to be that number of claims to which direct reference is made therein. 
For fee calculation purposes also, any claim depending from a multiple 
dependent claim will be considered to be that number of claims to which 
direct reference is made in that multiple dependent claim. In addition 
to the other filing fees, any original application which is filed with, 
or is amended to include, multiple dependent claims must have paid 
therein the fee set forth in Sec. 1.16(j). Claims in dependent form 
shall be construed to include all the limitations of the claim 
incorporated by reference into the dependent claim. A multiple dependent 
claim shall be construed to incorporate by reference all the limitations 
of each of the particular claims in relation to which it is being 
considered.
    (d)(1) The claim or claims must conform to the invention as set 
forth in the remainder of the specification and the terms and phrases 
used in the claims must find clear support or antecedent basis in the 
description so that the meaning of the terms in the claims may be 
ascertainable by reference to the description. (See Sec. 1.58(a).)
    (2) See Secs. 1.141 to 1.146 as to claiming different inventions in 
one application.
    (e) Where the nature of the case admits, as in the case of an 
improvement, any independent claim should contain in the following 
order:
    (1) A preamble comprising a general description of all the elements 
or steps

[[Page 76]]

of the claimed combination which are conventional or known,
    (2) A phrase such as ``wherein the improvement comprises,'' and
    (3) Those elements, steps and/or relationships which constitute that 
portion of the claimed combination which the applicant considers as the 
new or improved portion.
    (f) If there are several claims, they shall be numbered 
consecutively in Arabic numerals.
    (g) The least restrictive claim should be presented as claim number 
1, and all dependent claims should be grouped together with the claim or 
claims to which they refer to the extent practicable.
    (h) The claim or claims must commence on a separate physical sheet 
or electronic page. Any sheet including a claim or portion of a claim 
may not contain any other parts of the application or other material.
    (i) Where a claim sets forth a plurality of elements or steps, each 
element or step of the claim should be separated by a line indentation.

Sec. 1.76  Application data sheet.

    (a) Application data sheet. An application data sheet is a sheet or 
sheets that may be submitted in a provisional application under 35 
U.S.C. 111(b), a nonprovisional application under 35 U.S.C. 111(a), a 
nonprovisional international design application, or a national stage 
application under 35 U.S.C. 371 and must be submitted when required by 
Sec. 1.55 or 1.78 to claim priority to or the benefit of a prior-filed 
application under 35 U.S.C. 119, 120, 121, 365, or 386. An application 
data sheet must be titled ``Application Data Sheet.'' An application 
data sheet must contain all of the section headings listed in paragraph 
(b) of this section, except as provided in paragraph (c)(2) of this 
section, with any appropriate data for each section heading. If an 
application data sheet is provided, the application data sheet is part 
of the application for which it has been submitted.
    (b) Bibliographic data. Bibliographic data as used in paragraph (a) 
of this section includes:
    (1) Inventor information. This information includes the legal name, 
residence, and mailing address of the inventor or each joint inventor.
    (2) Correspondence information. This information includes the 
correspondence address, which may be indicated by reference to a 
customer number, to which correspondence is to be directed (see 
Sec. 1.33(a)).
    (3) Application information. This information includes the title of 
the invention, the total number of drawing sheets, a suggested drawing 
figure for publication (in a nonprovisional application), any docket 
number assigned to the application, the type of application (e.g., 
utility, plant, design, reissue, provisional), whether the application 
discloses any significant part of the subject matter of an application 
under a secrecy order pursuant to Sec. 5.2 of this chapter (see 
Sec. 5.2(c)), and, for plant applications, the Latin name of the genus 
and species of the plant claimed, as well as the variety denomination. 
When information concerning the previously filed application is required 
under Sec. 1.57(a), application information also includes the reference 
to the previously filed application, indicating that the specification 
and any drawings of the application are replaced by the reference to the 
previously filed application, and specifying the previously filed 
application by application number, filing date, and the intellectual 
property authority or country in which the previously filed application 
was filed.
    (4) Representative information. This information includes the 
registration number of each practitioner having a power of attorney in 
the application (preferably by reference to a customer number). 
Providing this information in the application data sheet does not 
constitute a power of attorney in the application (see Sec. 1.32).
    (5) Domestic benefit information. This information includes the 
application number, the filing date, the status (including patent number 
if available), and relationship of each application for

[[Page 77]]

which a benefit is claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 
386(c). Providing this information in the application data sheet 
constitutes the specific reference required by 35 U.S.C. 119(e) or 120 
and Sec. 1.78.
    (6) Foreign priority information. This information includes the 
application number, country (or intellectual property authority), and 
filing date of each foreign application for which priority is claimed. 
Providing this information in the application data sheet constitutes the 
claim for priority as required by 35 U.S.C. 119(b) and Sec. 1.55.
    (7) Applicant information: This information includes the name 
(either natural person or juristic entity) and address of the legal 
representative, assignee, person to whom the inventor is under an 
obligation to assign the invention, or person who otherwise shows 
sufficient proprietary interest in the matter who is the applicant under 
Sec. 1.43 or Sec. 1.46. Providing assignment information in the 
application data sheet does not substitute for compliance with any 
requirement of part 3 of this chapter to have an assignment recorded by 
the Office.
    (c) Correcting and updating an application data sheet. (1) 
Information in a previously submitted application data sheet, inventor's 
oath or declaration under Sec. 1.63, Sec. 1.64 or Sec. 1.67, or 
otherwise of record, may be corrected or updated until payment of the 
issue fee by a new application data sheet providing corrected or updated 
information, except that inventorship changes must comply with the 
requirements of Sec. 1.48, foreign priority and domestic benefit 
information changes must comply with Secs. 1.55 and 1.78, and 
correspondence address changes are governed by Sec. 1.33(a).
    (2) An application data sheet providing corrected or updated 
information may include all of the sections listed in paragraph (b) of 
this section or only those sections containing changed or updated 
information. The application data sheet must include the section 
headings listed in paragraph (b) of this section for each section 
included in the application data sheet, and must identify the 
information that is being changed, with underlining for insertions, and 
strike-through or brackets for text removed, except that identification 
of information being changed is not required for an application data 
sheet included with an initial submission under 35 U.S.C. 371.
    (d) Inconsistencies between application data sheet and other 
documents. For inconsistencies between information that is supplied by 
both an application data sheet under this section and other documents:
    (1) The most recent submission will govern with respect to 
inconsistencies as between the information provided in an application 
data sheet, a designation of a correspondence address, or by the 
inventor's oath or declaration, except that:
    (i) The most recent application data sheet will govern with respect 
to foreign priority (Sec. 1.55) or domestic benefit (Sec. 1.78) claims; 
and
    (ii) The naming of the inventorship is governed by Sec. 1.41 and 
changes to inventorship or the names of the inventors is governed by 
Sec. 1.48.
    (2) The information in the application data sheet will govern when 
inconsistent with the information supplied at the same time by a 
designation of correspondence address or the inventor's oath or 
declaration. The information in the application data sheet will govern 
when inconsistent with the information supplied at any time in a Patent 
Cooperation Treaty Request Form, Patent Law Treaty Model International 
Request Form, Patent Law Treaty Model International Request for 
Recordation of Change in Name or Address Form, or Patent Law Treaty 
Model International Request for Recordation of Change in Applicant or 
Owner Form.
    (3) The Office will capture bibliographic information from the 
application data sheet. The Office will generally not review the 
inventor's oath or declaration to determine if the bibliographic 
information contained therein is consistent with the bibliographic 
information provided in an application data sheet. Incorrect 
bibliographic information contained in an application data sheet may be 
corrected as provided in paragraph (c)(1) of this section.

[[Page 78]]

    (e) Signature requirement. An application data sheet must be signed 
in compliance with Sec. 1.33(b). An unsigned application data sheet will 
be treated only as a transmittal letter.
    (f) Patent Law Treaty Model International Forms. The requirement in 
Sec. 1.55 or Sec. 1.78 for the presentation of a priority or benefit 
claim under 35 U.S.C. 119, 120, 121, or 365 in an application data sheet 
will be satisfied by the presentation of such priority or benefit claim 
in the Patent Law Treaty Model International Request Form, and the 
requirement in Sec. 1.57(a) for a reference to the previously filed 
application in an application data sheet will be satisfied by the 
presentation of such reference to the previously filed application in 
the Patent Law Treaty Model International Request Form. The requirement 
in Sec. 1.46 for the presentation of the name of the applicant under 35 
U.S.C. 118 in an application data sheet will be satisfied by the 
presentation of the name of the applicant in the Patent Law Treaty Model 
International Request Form, Patent Law Treaty Model International 
Request for Recordation of Change in Name or Address Form, or Patent Law 
Treaty Model International Request for Recordation of Change in 
Applicant or Owner Form, as applicable.
    (g) Patent Cooperation Treaty Request Form. The requirement in 
Sec. 1.78 for the presentation of a benefit claim under 35 U.S.C. 119, 
120, 121, or 365 in an application data sheet will be satisfied in a 
national stage application under 35 U.S.C. 371 by the presentation of 
such benefit claim in the Patent Cooperation Treaty Request Form 
contained in the international application or the presence of such 
benefit claim on the front page of the publication of the international 
application under PCT Article 21(2). The requirement in Sec. 1.55 or 
Sec. 1.78 for the presentation of a priority or benefit claim under 35 
U.S.C. 119, 120, 121, or 365 in an application data sheet and the 
requirement in Sec. 1.46 for the presentation of the name of the 
applicant under 35 U.S.C. 118 in an application data sheet will be 
satisfied in an application under 35 U.S.C. 111 by the presentation of 
such priority or benefit claim and presentation of the name of the 
applicant in a Patent Cooperation Treaty Request Form. If a Patent 
Cooperation Treaty Request Form is submitted in an application under 35 
U.S.C. 111, the Patent Cooperation Treaty Request Form must be 
accompanied by a clear indication that treatment of the application as 
an application under 35 U.S.C. 111 is desired.

Sec. 1.78  Claiming benefit of earlier filing date and cross-references
to other applications.

    (a) Claims under 35 U.S.C. 119(e) for the benefit of a prior-filed 
provisional application. An applicant in a nonprovisional application, 
other than for a design patent, or an international application 
designating the United States may claim the benefit of one or more 
prior-filed provisional applications under the conditions set forth in 
35 U.S.C. 119(e) and this section.
    (1) The nonprovisional application or international application 
designating the United States must be:
    (i) Filed not later than twelve months after the date on which the 
provisional application was filed, subject to paragraph (b) of this 
section (a subsequent application); or
    (ii) Entitled to claim the benefit under 35 U.S.C. 120, 121, or 
365(c) of a subsequent application that was filed within the period set 
forth in paragraph (a)(1)(i) of this section.
    (2) Each prior-filed provisional application must name the inventor 
or a joint inventor named in the later-filed application as the inventor 
or a joint inventor. In addition, each prior-filed provisional 
application must be entitled to a filing date as set forth in 
Sec. 1.53(c), and the basic filing fee set forth in Sec. 1.16(d) must 
have been paid for such provisional application within the time period 
set forth in Sec. 1.53(g).
    (3) Any nonprovisional application or international application 
designating the United States that claims the benefit of one or more 
prior-filed provisional applications must contain, or be amended to 
contain, a reference to each such prior-filed provisional application, 
identifying it by the provisional application number (consisting of 
series code and serial number). If the later-filed application is a 
nonprovisional application, the reference required by this paragraph 
must be included in an application data sheet (Sec. 1.76(b)(5)).
    (4) The reference required by paragraph (a)(3) of this section must 
be submitted during the pendency of the later-filed application. If the 
later-filed application is an application filed under 35 U.S.C. 111(a), 
this reference must also be submitted within the later of four months 
from the actual filing date of the later-filed application or sixteen 
months from the filing date of the prior-filed provisional application. 
If the later-filed application is a nonprovisional application entering 
the national stage from an international application under 35 U.S.C. 
371, this reference must also be submitted within the later of four 
months from the date on which the national stage commenced under 35 
U.S.C. 371(b) or (f) (Sec. 1.491(a)), four months from the date of the 
initial submission under 35 U.S.C. 371 to enter the national stage, or 
sixteen months from the filing date of the prior-filed provisional 
application. Except as provided in paragraph (c) of this section, 
failure to timely submit the reference is considered a waiver of any 
benefit under 35 U.S.C. 119(e) of the prior-filed provisional 
application. The time periods in this paragraph do not apply if the 
later-filed application is:
    (i) An application filed under 35 U.S.C. 111(a) before November 29, 
2000; or
    (ii) An international application filed under 35 U.S.C. 363 before 
November 29, 2000.
    (5) If the prior-filed provisional application was filed in a 
language other than English and both an English-language translation of 
the prior-filed provisional application and a statement that the 
translation is accurate were not previously filed in the prior-filed 
provisional application, the applicant will be notified and given a 
period of time within which to file, in the prior-filed provisional 
application, the translation and the statement. If the notice is mailed 
in a pending nonprovisional application, a timely reply to such a

[[Page 80]]

notice must include the filing in the nonprovisional application of 
either a confirmation that the translation and statement were filed in 
the provisional application, or an application data sheet 
(Sec. 1.76(b)(5)) eliminating the reference under paragraph (a)(3) of 
this section to the prior-filed provisional application, or the 
nonprovisional application will be abandoned. The translation and 
statement may be filed in the provisional application, even if the 
provisional application has become abandoned.
    (6) If a nonprovisional application filed on or after March 16, 
2013, claims the benefit of the filing date of a provisional application 
filed prior to March 16, 2013, and also contains, or contained at any 
time, a claim to a claimed invention that has an effective filing date 
as defined in Sec. 1.109 that is on or after March 16, 2013, the 
applicant must provide a statement to that effect within the later of 
four months from the actual filing date of the nonprovisional 
application, four months from the date of entry into the national stage 
as set forth in Sec. 1.491 in an international application, sixteen 
months from the filing date of the prior-filed provisional application, 
or the date that a first claim to a claimed invention that has an 
effective filing date on or after March 16, 2013, is presented in the 
nonprovisional application. An applicant is not required to provide such 
a statement if the applicant reasonably believes on the basis of 
information already known to the individuals designated in Sec. 1.56(c) 
that the nonprovisional application does not, and did not at any time, 
contain a claim to a claimed invention that has an effective filing date 
on or after March 16, 2013.
    (b) Delayed filing of the subsequent nonprovisional application or 
international application designating the United States. If the 
subsequent nonprovisional application or international application 
designating the United States has a filing date which is after the 
expiration of the twelve-month period set forth in paragraph (a)(1)(i) 
of this section but within two months from the expiration of the period 
set forth in paragraph (a)(1)(i) of this section, the benefit of the 
provisional application may be restored under PCT Rule 26bis.3 for an 
international application, or upon petition pursuant to this paragraph, 
if the delay in filing the subsequent nonprovisional application or 
international application designating the United States within the 
period set forth in paragraph (a)(1)(i) of this section was 
unintentional.
    (1) A petition to restore the benefit of a provisional application 
under this paragraph filed on or after May 13, 2015, must be filed in 
the subsequent application, and any petition to restore the benefit of a 
provisional application under this paragraph must include:
    (i) The reference required by 35 U.S.C. 119(e) to the prior-filed 
provisional application in an application data sheet (Sec. 1.76(b)(5)) 
identifying it by provisional application number (consisting of series 
code and serial number), unless previously submitted;
    (ii) The petition fee as set forth in Sec. 1.17(m); and
    (iii) A statement that the delay in filing the subsequent 
nonprovisional application or international application designating the 
United States within the twelve-month period set forth in paragraph 
(a)(1)(i) of this section was unintentional. The Director may require 
additional information where there is a question whether the delay was 
unintentional.
    (2) The restoration of the right of priority under PCT Rule 26bis.3 
to a provisional application does not affect the requirement to include 
the reference required by paragraph (a)(3) of this section to the 
provisional application in a national stage application under 35 U.S.C. 
371 within the time period provided by paragraph (a)(4) of this section 
to avoid the benefit claim being considered waived.
    (c) Delayed claims under 35 U.S.C. 119(e) for the benefit of a 
prior-filed provisional application. If the reference required by 35 
U.S.C. 119(e) and paragraph (a)(3) of this section is presented in an 
application after the time period provided by paragraph (a)(4) of this 
section, the claim under 35 U.S.C. 119(e) for the benefit of a prior-
filed provisional application may be accepted if the reference 
identifying the prior-filed application by provisional application 
number was unintentionally delayed. A

[[Page 81]]

petition to accept an unintentionally delayed claim under 35 U.S.C. 
119(e) for the benefit of a prior-filed provisional application must be 
accompanied by:
    (1) The reference required by 35 U.S.C. 119(e) and paragraph (a)(3) 
of this section to the prior-filed provisional application, unless 
previously submitted;
    (2) The petition fee as set forth in Sec. 1.17(m); and
    (3) A statement that the entire delay between the date the benefit 
claim was due under paragraph (a)(4) of this section and the date the 
benefit claim was filed was unintentional. The Director may require 
additional information where there is a question whether the delay was 
unintentional.
    (d) Claims under 35 U.S.C. 120, 121, 365(c), or 386(c) for the 
benefit of a prior-filed nonprovisional application, international 
application, or international design application. An applicant in a 
nonprovisional application (including a nonprovisional application 
resulting from an international application or international design 
application), an international application designating the United 
States, or an international design application designating the United 
States may claim the benefit of one or more prior-filed copending 
nonprovisional applications, international applications designating the 
United States, or international design applications designating the 
United States under the conditions set forth in 35 U.S.C. 120, 121, 
365(c), or 386(c) and this section.
    (1) Each prior-filed application must name the inventor or a joint 
inventor named in the later-filed application as the inventor or a joint 
inventor. In addition, each prior-filed application must either be:
    (i) An international application entitled to a filing date in 
accordance with PCT Article 11 and designating the United States;
    (ii) An international design application entitled to a filing date 
in accordance with Sec. 1.1023 and designating the United States; or
    (iii) A nonprovisional application under 35 U.S.C. 111(a) that is 
entitled to a filing date as set forth in Sec. 1.53(b) or (d) for which 
the basic filing fee set forth in Sec. 1.16 has been paid within the 
pendency of the application.
    (2) Except for a continued prosecution application filed under 
Sec. 1.53(d), any nonprovisional application, international application 
designating the United States, or international design application 
designating the United States that claims the benefit of one or more 
prior-filed nonprovisional applications, international applications 
designating the United States, or international design applications 
designating the United States must contain or be amended to contain a 
reference to each such prior-filed application, identifying it by 
application number (consisting of the series code and serial number), 
international application number and international filing date, or 
international registration number and filing date under Sec. 1.1023. If 
the later-filed application is a nonprovisional application, the 
reference required by this paragraph must be included in an application 
data sheet (Sec. 1.76(b)(5)). The reference also must identify the 
relationship of the applications, namely, whether the later-filed 
application is a continuation, divisional, or continuation-in-part of 
the prior-filed nonprovisional application, international application, 
or international design application.
    (3)(i) The reference required by 35 U.S.C. 120 and paragraph (d)(2) 
of this section must be submitted during the pendency of the later-filed 
application.
    (ii) If the later-filed application is an application filed under 35 
U.S.C. 111(a), this reference must also be submitted within the later of 
four months from the actual filing date of the later-filed application 
or sixteen months from the filing date of the prior-filed application. 
If the later-filed application is a nonprovisional application entering 
the national stage from an international application under 35 U.S.C. 
371, this reference must also be submitted within the later of four 
months from the date on which the national stage commenced under 35 
U.S.C. 371(b) or (f) (Sec. 1.491(a)), four months from the date of the 
initial submission under 35 U.S.C. 371 to enter the national stage, or 
sixteen months from the filing date of the prior-filed application. The 
time

[[Page 82]]

periods in this paragraph do not apply if the later-filed application 
is:
    (A) An application for a design patent;
    (B) An application filed under 35 U.S.C. 111(a) before November 29, 
2000; or
    (C) An international application filed under 35 U.S.C. 363 before 
November 29, 2000.
    (iii) Except as provided in paragraph (e) of this section, failure 
to timely submit the reference required by 35 U.S.C. 120 and paragraph 
(d)(2) of this section is considered a waiver of any benefit under 35 
U.S.C. 120, 121, 365(c), or 386(c) to the prior-filed application.
    (4) The request for a continued prosecution application under 
Sec. 1.53(d) is the specific reference required by 35 U.S.C. 120 to the 
prior-filed application. The identification of an application by 
application number under this section is the identification of every 
application assigned that application number necessary for a specific 
reference required by 35 U.S.C. 120 to every such application assigned 
that application number.
    (5) Cross-references to other related applications may be made when 
appropriate (see Sec. 1.14), but cross-references to applications for 
which a benefit is not claimed under title 35, United States Code, must 
not be included in an application data sheet (Sec. 1.76(b)(5)).
    (6) If a nonprovisional application filed on or after March 16, 
2013, other than a nonprovisional international design application, 
claims the benefit of the filing date of a nonprovisional application or 
an international application designating the United States filed prior 
to March 16, 2013, and also contains, or contained at any time, a claim 
to a claimed invention that has an effective filing date as defined in 
Sec. 1.109 that is on or after March 16, 2013, the applicant must 
provide a statement to that effect within the later of four months from 
the actual filing date of the later-filed application, four months from 
the date of entry into the national stage as set forth in Sec. 1.491 in 
an international application, sixteen months from the filing date of the 
prior-filed application, or the date that a first claim to a claimed 
invention that has an effective filing date on or after March 16, 2013, 
is presented in the later-filed application. An applicant is not 
required to provide such a statement if either:
    (i) The application claims the benefit of a nonprovisional 
application in which a statement under Sec. 1.55(k), paragraph (a)(6) of 
this section, or this paragraph that the application contains, or 
contained at any time, a claim to a claimed invention that has an 
effective filing date on or after March 16, 2013 has been filed; or
    (ii) The applicant reasonably believes on the basis of information 
already known to the individuals designated in Sec. 1.56(c) that the 
later filed application does not, and did not at any time, contain a 
claim to a claimed invention that has an effective filing date on or 
after March 16, 2013.
    (7) Where benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 
386(c) to an international application or an international design 
application which designates but did not originate in the United States, 
the Office may require a certified copy of such application together 
with an English translation thereof if filed in another language.
    (e) Delayed claims under 35 U.S.C. 120, 121, 365(c), or 386(c) for 
the benefit of a prior-filed nonprovisional application, international 
application, or international design application. If the reference 
required by 35 U.S.C. 120 and paragraph (d)(2) of this section is 
presented after the time period provided by paragraph (d)(3) of this 
section, the claim under 35 U.S.C. 120, 121, 365(c), or 386(c) for the 
benefit of a prior-filed copending nonprovisional application, 
international application designating the United States, or 
international design application designating the United States may be 
accepted if the reference required by paragraph (d)(2) of this section 
was unintentionally delayed. A petition to accept an unintentionally 
delayed claim under 35 U.S.C. 120, 121, 365(c), or 386(c) for the 
benefit of a prior-filed application must be accompanied by:
    (1) The reference required by 35 U.S.C. 120 and paragraph (d)(2) of 
this section to the prior-filed application, unless previously 
submitted;
    (2) The petition fee as set forth in Sec. 1.17(m); and

[[Page 83]]

    (3) A statement that the entire delay between the date the benefit 
claim was due under paragraph (d)(3) of this section and the date the 
benefit claim was filed was unintentional. The Director may require 
additional information where there is a question whether the delay was 
unintentional.
    (f) Applications containing patentably indistinct claims. Where two 
or more applications filed by the same applicant or assignee contain 
patentably indistinct claims, elimination of such claims from all but 
one application may be required in the absence of good and sufficient 
reason for their retention during pendency in more than one application.
    (g) Applications or patents under reexamination naming different 
inventors and containing patentably indistinct claims. If an application 
or a patent under reexamination and at least one other application 
naming different inventors are owned by the same person and contain 
patentably indistinct claims, and there is no statement of record 
indicating that the claimed inventions were commonly owned or subject to 
an obligation of assignment to the same person on the effective filing 
date (as defined in Sec. 1.109), or on the date of the invention, as 
applicable, of the later claimed invention, the Office may require the 
applicant or assignee to state whether the claimed inventions were 
commonly owned or subject to an obligation of assignment to the same 
person on such date, and if not, indicate which named inventor is the 
prior inventor, as applicable. Even if the claimed inventions were 
commonly owned, or subject to an obligation of assignment to the same 
person on the effective filing date (as defined in Sec. 1.109), or on 
the date of the invention, as applicable, of the later claimed 
invention, the patentably indistinct claims may be rejected under the 
doctrine of double patenting in view of such commonly owned or assigned 
applications or patents under reexamination.
    (h) Applications filed before September 16, 2012. Notwithstanding 
the requirement in paragraphs (a)(3) and (d)(2) of this section that any 
specific reference to a prior-filed application be presented in an 
application data sheet (Sec. 1.76), this requirement in paragraph (a)(3) 
and (d)(2) of this section will be satisfied by the presentation of such 
specific reference in the first sentence(s) of the specification 
following the title in a nonprovisional application filed under 35 
U.S.C. 111(a) before September 16, 2012, or resulting from an 
international application filed under 35 U.S.C. 363 before September 16, 
2012. The provisions of this paragraph do not apply to any specific 
reference submitted for a petition under paragraph (b) of this section 
to restore the benefit of a provisional application.
    (i) Petitions required in international applications. If a petition 
under paragraph (b), (c), or (e) of this section is required in an 
international application that was not filed with the United States 
Receiving Office and is not a nonprovisional application, then such 
petition may be filed in the earliest nonprovisional application that 
claims benefit under 35 U.S.C. 120, 121, 365(c), or 386(c) to the 
international application and will be treated as having been filed in 
the international application.
    (j) Benefit under 35 U.S.C. 386(c). Benefit under 35 U.S.C. 386(c) 
with respect to an international design application is applicable only 
to nonprovisional applications, international applications, and 
international design applications filed on or after May 13, 2015, and 
patents issuing thereon.
    (k) Time periods in this section. The time periods set forth in this 
section are not extendable, but are subject to 35 U.S.C. 21(b) (and 
Sec. 1.7(a)), PCT Rule 80.5, and Hague Agreement Rule 4(4).

[80 FR 17959, Apr. 2, 2015]



Sec. 1.79  Reservation clauses not permitted.

    A reservation for a future application of subject matter disclosed 
but not claimed in a pending application will not be permitted in the 
pending application, but an application disclosing unclaimed subject 
matter may contain a reference to a later filed application of the same 
applicant or owned by a common assignee disclosing and claiming that 
subject matter.

[[Page 84]]



Sec. 1.81  Drawings required in patent application.

    (a) The applicant for a patent is required to furnish a drawing of 
the invention where necessary for the understanding of the subject 
matter sought to be patented. Since corrections are the responsibility 
of the applicant, the original drawing(s) should be retained by the 
applicant for any necessary future correction.
    (b) Drawings may include illustrations which facilitate an 
understanding of the invention (for example, flow sheets in cases of 
processes, and diagrammatic views).
    (c) Whenever the nature of the subject matter sought to be patented 
admits of illustration by a drawing without its being necessary for the 
understanding of the subject matter and the applicant has not furnished 
such a drawing, the examiner will require its submission within a time 
period of not less than two months from the date of the sending of a 
notice thereof.
    (d) Drawings submitted after the filing date of the application may 
not be used to overcome any insufficiency of the specification due to 
lack of an enabling disclosure or otherwise inadequate disclosure 
therein, or to supplement the original disclosure thereof for the 
purpose of interpretation of the scope of any claim.

[43 FR 4015, Jan. 31, 1978, as amended at 53 FR 47808, Nov. 28, 1988; 77 
FR 48821, Aug. 14, 2012; 78 FR 62404, Oct. 21, 2013]



Sec. 1.83  Content of drawing.

    (a) The drawing in a nonprovisional application must show every 
feature of the invention specified in the claims. However, conventional 
features disclosed in the description and claims, where their detailed 
illustration is not essential for a proper understanding of the 
invention, should be illustrated in the drawing in the form of a 
graphical drawing symbol or a labeled representation (e.g., a labeled 
rectangular box). In addition, tables that are included in the 
specification and sequences that are included in sequence listings 
should not be duplicated in the drawings.
    (b) When the invention consists of an improvement on an old machine 
the drawing must when possible exhibit, in one or more views, the 
improved portion itself, disconnected from the old structure, and also 
in another view, so much only of the old structure as will suffice to 
show the connection of the invention therewith.
    (c) Where the drawings in a nonprovisional application do not comply 
with the requirements of paragraphs (a) and (b) of this section, the 
examiner shall require such additional illustration within a time period 
of not less than two months from the date of the sending of a notice 
thereof. Such corrections are subject to the requirements of 
Sec. 1.81(d).

[31 FR 12923, Oct. 4, 1966, as amended at 43 FR 4015, Jan. 31, 1978; 60 
FR 20226, Apr. 25, 1995; 69 FR 56541, Sept. 21, 2004; 78 FR 62405, Oct. 
21, 2013]



Sec. 1.84  Standards for drawings.

    (a) Drawings. There are two acceptable categories for presenting 
drawings in utility and design patent applications.
    (1) Black ink. Black and white drawings are normally required. India 
ink, or its equivalent that secures solid black lines, must be used for 
drawings; or
    (2) Color. Color drawings are permitted in design applications. 
Where a design application contains color drawings, the application must 
include the number of sets of color drawings required by paragraph 
(a)(2)(ii) of this section and the specification must contain the 
reference required by paragraph (a)(2)(iii) of this section. On rare 
occasions, color drawings may be necessary as the only practical medium 
by which to disclose the subject matter sought to be patented in a 
utility patent application. The color drawings must be of sufficient 
quality such that all details in the drawings are reproducible in black 
and white in the printed patent. Color drawings are not permitted in 
international applications (see PCT Rule 11.13). The Office will accept 
color drawings in utility patent applications only after granting a 
petition filed under this paragraph explaining why the color drawings 
are necessary. Any such petition must include the following:
    (i) The fee set forth in Sec. 1.17(h);

[[Page 85]]

    (ii) One (1) set of color drawings if submitted via the Office 
electronic filing system or three (3) sets of color drawings if not 
submitted via the Office electronic filing system; and
    (iii) An amendment to the specification to insert (unless the 
specification contains or has been previously amended to contain) the 
following language as the first paragraph of the brief description of 
the drawings:

The patent or application file contains at least one drawing executed in 
color. Copies of this patent or patent application publication with 
color drawing(s) will be provided by the Office upon request and payment 
of the necessary fee.

    (b) Photographs--(1) Black and white. Photographs, including 
photocopies of photographs, are not ordinarily permitted in utility and 
design patent applications. The Office will accept photographs in 
utility and design patent applications, however, if photographs are the 
only practicable medium for illustrating the claimed invention. For 
example, photographs or photomicrographs of: electrophoresis gels, blots 
(e.g., immunological, western, Southern, and northern), autoradiographs, 
cell cultures (stained and unstained), histological tissue cross 
sections (stained and unstained), animals, plants, in vivo imaging, thin 
layer chromatography plates, crystalline structures, and, in a design 
patent application, ornamental effects, are acceptable. If the subject 
matter of the application admits of illustration by a drawing, the 
examiner may require a drawing in place of the photograph. The 
photographs must be of sufficient quality so that all details in the 
photographs are reproducible in the printed patent.
    (2) Color photographs. Color photographs will be accepted in utility 
and design patent applications if the conditions for accepting color 
drawings and black and white photographs have been satisfied. See 
paragraphs (a)(2) and (b)(1) of this section.
    (c) Identification of drawings. Identifying indicia should be 
provided, and if provided, should include the title of the invention, 
inventor's name, and application number, or docket number (if any) if an 
application number has not been assigned to the application. If this 
information is provided, it must be placed on the front of each sheet 
within the top margin. Each drawing sheet submitted after the filing 
date of an application must be identified as either ``Replacement 
Sheet'' or ``New Sheet'' pursuant to Sec. 1.121(d). If a marked-up copy 
of any amended drawing figure including annotations indicating the 
changes made is filed, such marked-up copy must be clearly labeled as 
``Annotated Sheet'' pursuant to Sec. 1.121(d)(1).
    (d) Graphic forms in drawings. Chemical or mathematical formulae, 
tables, and waveforms may be submitted as drawings, and are subject to 
the same requirements as drawings. Each chemical or mathematical formula 
must be labeled as a separate figure, using brackets when necessary, to 
show that information is properly integrated. Each group of waveforms 
must be presented as a single figure, using a common vertical axis with 
time extending along the horizontal axis. Each individual waveform 
discussed in the specification must be identified with a separate letter 
designation adjacent to the vertical axis.
    (e) Type of paper. Drawings submitted to the Office must be made on 
paper which is flexible, strong, white, smooth, non-shiny, and durable. 
All sheets must be reasonably free from cracks, creases, and folds. Only 
one side of the sheet may be used for the drawing. Each sheet must be 
reasonably free from erasures and must be free from alterations, 
overwritings, and interlineations. Photographs must be developed on 
paper meeting the sheet-size requirements of paragraph (f) of this 
section and the margin requirements of paragraph (g) of this section. 
See paragraph (b) of this section for other requirements for 
photographs.
    (f) Size of paper. All drawing sheets in an application must be the 
same size. One of the shorter sides of the sheet is regarded as its top. 
The size of the sheets on which drawings are made must be:
    (1) 21.0 cm. by 29.7 cm. (DIN size A4), or
    (2) 21.6 cm. by 27.9 cm. (8\1/2\ by 11 inches).
    (g) Margins. The sheets must not contain frames around the sight 
(i.e., the usable surface), but should have scan

[[Page 86]]

target points (i.e., cross-hairs) printed on two catercorner margin 
corners. Each sheet must include a top margin of at least 2.5 cm. (1 
inch), a left side margin of at least 2.5 cm. (1 inch), a right side 
margin of at least 1.5 cm. (\5/8\ inch), and a bottom margin of at least 
1.0 cm. (\3/8\ inch), thereby leaving a sight no greater than 17.0 cm. 
by 26.2 cm. on 21.0 cm. by 29.7 cm. (DIN size A4) drawing sheets, and a 
sight no greater than 17.6 cm. by 24.4 cm. (6\15/16\ by 9\5/8\ inches) 
on 21.6 cm. by 27.9 cm. (8\1/2\ by 11 inch) drawing sheets.
    (h) Views. The drawing must contain as many views as necessary to 
show the invention. The views may be plan, elevation, section, or 
perspective views. Detail views of portions of elements, on a larger 
scale if necessary, may also be used. All views of the drawing must be 
grouped together and arranged on the sheet(s) without wasting space, 
preferably in an upright position, clearly separated from one another, 
and must not be included in the sheets containing the specifications, 
claims, or abstract. Views must not be connected by projection lines and 
must not contain center lines. Waveforms of electrical signals may be 
connected by dashed lines to show the relative timing of the waveforms.
    (1) Exploded views. Exploded views, with the separated parts 
embraced by a bracket, to show the relationship or order of assembly of 
various parts are permissible. When an exploded view is shown in a 
figure which is on the same sheet as another figure, the exploded view 
should be placed in brackets.
    (2) Partial views. When necessary, a view of a large machine or 
device in its entirety may be broken into partial views on a single 
sheet, or extended over several sheets if there is no loss in facility 
of understanding the view. Partial views drawn on separate sheets must 
always be capable of being linked edge to edge so that no partial view 
contains parts of another partial view. A smaller scale view should be 
included showing the whole formed by the partial views and indicating 
the positions of the parts shown. When a portion of a view is enlarged 
for magnification purposes, the view and the enlarged view must each be 
labeled as separate views.
    (i) Where views on two or more sheets form, in effect, a single 
complete view, the views on the several sheets must be so arranged that 
the complete figure can be assembled without concealing any part of any 
of the views appearing on the various sheets.
    (ii) A very long view may be divided into several parts placed one 
above the other on a single sheet. However, the relationship between the 
different parts must be clear and unambiguous.
    (3) Sectional views. The plane upon which a sectional view is taken 
should be indicated on the view from which the section is cut by a 
broken line. The ends of the broken line should be designated by Arabic 
or Roman numerals corresponding to the view number of the sectional 
view, and should have arrows to indicate the direction of sight. 
Hatching must be used to indicate section portions of an object, and 
must be made by regularly spaced oblique parallel lines spaced 
sufficiently apart to enable the lines to be distinguished without 
difficulty. Hatching should not impede the clear reading of the 
reference characters and lead lines. If it is not possible to place 
reference characters outside the hatched area, the hatching may be 
broken off wherever reference characters are inserted. Hatching must be 
at a substantial angle to the surrounding axes or principal lines, 
preferably 45. A cross section must be set out and drawn to show all of 
the materials as they are shown in the view from which the cross section 
was taken. The parts in cross section must show proper material(s) by 
hatching with regularly spaced parallel oblique strokes, the space 
between strokes being chosen on the basis of the total area to be 
hatched. The various parts of a cross section of the same item should be 
hatched in the same manner and should accurately and graphically 
indicate the nature of the material(s) that is illustrated in cross 
section. The hatching of juxtaposed different elements must be angled in 
a different way. In the case of large areas, hatching may be confined to 
an edging drawn around the entire inside of the outline of the area to 
be hatched. Different types of hatching should have different 
conventional

[[Page 87]]

meanings as regards the nature of a material seen in cross section.
    (4) Alternate position. A moved position may be shown by a broken 
line superimposed upon a suitable view if this can be done without 
crowding; otherwise, a separate view must be used for this purpose.
    (5) Modified forms. Modified forms of construction must be shown in 
separate views.
    (i) Arrangement of views. One view must not be placed upon another 
or within the outline of another. All views on the same sheet should 
stand in the same direction and, if possible, stand so that they can be 
read with the sheet held in an upright position. If views wider than the 
width of the sheet are necessary for the clearest illustration of the 
invention, the sheet may be turned on its side so that the top of the 
sheet, with the appropriate top margin to be used as the heading space, 
is on the right-hand side. Words must appear in a horizontal, left-to-
right fashion when the page is either upright or turned so that the top 
becomes the right side, except for graphs utilizing standard scientific 
convention to denote the axis of abscissas (of X) and the axis of 
ordinates (of Y).
    (j) Front page view. The drawing must contain as many views as 
necessary to show the invention. One of the views should be suitable for 
inclusion on the front page of the patent application publication and 
patent as the illustration of the invention. Views must not be connected 
by projection lines and must not contain center lines. Applicant may 
suggest a single view (by figure number) for inclusion on the front page 
of the patent application publication and patent.
    (k) Scale. The scale to which a drawing is made must be large enough 
to show the mechanism without crowding when the drawing is reduced in 
size to two-thirds in reproduction. Indications such as ``actual size'' 
or ``scale \1/2\'' on the drawings are not permitted since these lose 
their meaning with reproduction in a different format.
    (l) Character of lines, numbers, and letters. All drawings must be 
made by a process which will give them satisfactory reproduction 
characteristics. Every line, number, and letter must be durable, clean, 
black (except for color drawings), sufficiently dense and dark, and 
uniformly thick and well-defined. The weight of all lines and letters 
must be heavy enough to permit adequate reproduction. This requirement 
applies to all lines however fine, to shading, and to lines representing 
cut surfaces in sectional views. Lines and strokes of different 
thicknesses may be used in the same drawing where different thicknesses 
have a different meaning.
    (m) Shading. The use of shading in views is encouraged if it aids in 
understanding the invention and if it does not reduce legibility. 
Shading is used to indicate the surface or shape of spherical, 
cylindrical, and conical elements of an object. Flat parts may also be 
lightly shaded. Such shading is preferred in the case of parts shown in 
perspective, but not for cross sections. See paragraph (h)(3) of this 
section. Spaced lines for shading are preferred. These lines must be 
thin, as few in number as practicable, and they must contrast with the 
rest of the drawings. As a substitute for shading, heavy lines on the 
shade side of objects can be used except where they superimpose on each 
other or obscure reference characters. Light should come from the upper 
left corner at an angle of 45. Surface delineations should preferably 
be shown by proper shading. Solid black shading areas are not permitted, 
except when used to represent bar graphs or color.
    (n) Symbols. Graphical drawing symbols may be used for conventional 
elements when appropriate. The elements for which such symbols and 
labeled representations are used must be adequately identified in the 
specification. Known devices should be illustrated by symbols which have 
a universally recognized conventional meaning and are generally accepted 
in the art. Other symbols which are not universally recognized may be 
used, subject to approval by the Office, if they are not likely to be 
confused with existing conventional symbols, and if they are readily 
identifiable.
    (o) Legends. Suitable descriptive legends may be used subject to 
approval by the Office, or may be required by the examiner where 
necessary for understanding of the drawing. They

[[Page 88]]

should contain as few words as possible.
    (p) Numbers, letters, and reference characters. (1) Reference 
characters (numerals are preferred), sheet numbers, and view numbers 
must be plain and legible, and must not be used in association with 
brackets or inverted commas, or enclosed within outlines, e.g., 
encircled. They must be oriented in the same direction as the view so as 
to avoid having to rotate the sheet. Reference characters should be 
arranged to follow the profile of the object depicted.
    (2) The English alphabet must be used for letters, except where 
another alphabet is customarily used, such as the Greek alphabet to 
indicate angles, wavelengths, and mathematical formulas.
    (3) Numbers, letters, and reference characters must measure at least 
.32 cm. (\1/8\ inch) in height. They should not be placed in the drawing 
so as to interfere with its comprehension. Therefore, they should not 
cross or mingle with the lines. They should not be placed upon hatched 
or shaded surfaces. When necessary, such as indicating a surface or 
cross section, a reference character may be underlined and a blank space 
may be left in the hatching or shading where the character occurs so 
that it appears distinct.
    (4) The same part of an invention appearing in more than one view of 
the drawing must always be designated by the same reference character, 
and the same reference character must never be used to designate 
different parts.
    (5) Reference characters not mentioned in the description shall not 
appear in the drawings. Reference characters mentioned in the 
description must appear in the drawings.
    (q) Lead lines. Lead lines are those lines between the reference 
characters and the details referred to. Such lines may be straight or 
curved and should be as short as possible. They must originate in the 
immediate proximity of the reference character and extend to the feature 
indicated. Lead lines must not cross each other. Lead lines are required 
for each reference character except for those which indicate the surface 
or cross section on which they are placed. Such a reference character 
must be underlined to make it clear that a lead line has not been left 
out by mistake. Lead lines must be executed in the same way as lines in 
the drawing. See paragraph (l) of this section.
    (r) Arrows. Arrows may be used at the ends of the lines, provided 
that their meaning is clear, as follows:
    (1) On a lead line, a freestanding arrow to indicate the entire 
section towards which it points;
    (2) On a lead line, an arrow touching a line to indicate the surface 
shown by the line looking along the direction of the arrow; or
    (3) To show the direction of movement.
    (s) Copyright or Mask Work Notice. A copyright or mask work notice 
may appear in the drawing, but must be placed within the sight of the 
drawing immediately below the figure representing the copyright or mask 
work material and be limited to letters having a print size of .32 cm. 
to .64 cm. (\1/8\ to \1/4\ inches) high. The content of the notice must 
be limited to only those elements provided for by law. For example, 
`` 1983 John Doe'' (17 U.S.C. 401) and ``*M* John 
Doe'' (17 U.S.C. 909) would be properly limited and, under current 
statutes, legally sufficient notices of copyright and mask work, 
respectively. Inclusion of a copyright or mask work notice will be 
permitted only if the authorization language set forth in Sec. 1.71(e) 
is included at the beginning (preferably as the first paragraph) of the 
specification.
    (t) Numbering of sheets of drawings. The sheets of drawings should 
be numbered in consecutive Arabic numerals, starting with 1, within the 
sight as defined in paragraph (g) of this section. These numbers, if 
present, must be placed in the middle of the top of the sheet, but not 
in the margin. The numbers can be placed on the right-hand side if the 
drawing extends too close to the middle of the top edge of the usable 
surface. The drawing sheet numbering must be clear and larger than the 
numbers used as reference characters to avoid confusion. The number of 
each sheet should be shown by two Arabic numerals placed on either side 
of an oblique line, with the first being the sheet number, and the 
second being the

[[Page 89]]

total number of sheets of drawings, with no other marking.
    (u) Numbering of views. (1) The different views must be numbered in 
consecutive Arabic numerals, starting with 1, independent of the 
numbering of the sheets and, if possible, in the order in which they 
appear on the drawing sheet(s). Partial views intended to form one 
complete view, on one or several sheets, must be identified by the same 
number followed by a capital letter. View numbers must be preceded by 
the abbreviation ``FIG.'' Where only a single view is used in an 
application to illustrate the claimed invention, it must not be numbered 
and the abbreviation ``FIG.'' must not appear.
    (2) Numbers and letters identifying the views must be simple and 
clear and must not be used in association with brackets, circles, or 
inverted commas. The view numbers must be larger than the numbers used 
for reference characters.
    (v) Security markings. Authorized security markings may be placed on 
the drawings provided they are outside the sight, preferably centered in 
the top margin.
    (w) Corrections. Any corrections on drawings submitted to the Office 
must be durable and permanent.
    (x) Holes. No holes should be made by applicant in the drawing 
sheets.
    (y) Types of drawings. See Sec. 1.152 for design drawings, 
Sec. 1.1026 for international design reproductions, Sec. 1.165 for plant 
drawings, and Sec. 1.173(a)(2) for reissue drawings.

Sec. 1.85  Corrections to drawings.

    (a) A utility or plant application will not be placed on the files 
for examination until objections to the drawings have been corrected. 
Except as provided in Sec. 1.215(c), any patent application publication 
will not include drawings filed after the application has been placed on 
the files for examination. Unless applicant is otherwise notified in an 
Office action, objections to the drawings in a utility or plant 
application will not be held in abeyance, and a request to hold 
objections to the drawings in abeyance will not be considered a bona 
fide attempt to advance the application to final action (Sec. 1.135(c)). 
If a drawing in a design application meets the requirements of 
Sec. 1.84(e), (f), and (g) and is suitable for reproduction, but is not 
otherwise in compliance with Sec. 1.84, the drawing may be admitted for 
examination.
    (b) The Office will not release drawings for purposes of correction. 
If corrections are necessary, new corrected drawings must be submitted 
within the time set by the Office.
    (c) If a corrected drawing is required or if a drawing does not 
comply with Sec. 1.84 or an amended drawing submitted under 
Sec. 1.121(d) in a nonprovisional international design application does 
not comply with Sec. 1.1026 at the time an application is allowed, the 
Office may notify the applicant in a notice of allowability and set a 
three-month period of time from the mail date of the notice of 
allowability within which the applicant must file a corrected drawing in 
compliance with Sec. 1.84 or 1.1026, as applicable, to avoid 
abandonment. This time period is not extendable under Sec. 1.136 (see 
Sec. 1.136(c)).

Sec. 1.92  [Reserved]



Sec. 1.93  Specimens.

    When the invention relates to a composition of matter, the applicant 
may be required to furnish specimens of the composition, or of its 
ingredients or intermediates, for the purpose of inspection or 
experiment.



Sec. 1.94  Return of models, exhibits or specimens.

    (a) Models, exhibits, or specimens may be returned to the applicant 
if no longer necessary for the conduct of business before the Office. 
When applicant is notified that a model, exhibit, or specimen is no 
longer necessary for the conduct of business before the Office and will 
be returned, applicant must arrange for the return of the model, 
exhibit, or specimen at the applicant's expense. The Office will dispose 
of perishables without notice to applicant unless applicant notifies the 
Office upon submission of the model, exhibit or specimen that a return 
is desired and makes arrangements for its return promptly upon 
notification by the Office that the model, exhibit or specimen is no 
longer necessary for the conduct of business before the Office.
    (b) Applicant is responsible for retaining the actual model, 
exhibit, or specimen for the enforceable life of any patent resulting 
from the application. The provisions of this paragraph do not apply to a 
model or exhibit that substantially conforms to the requirements of 
Sec. 1.52 or Sec. 1.84, where the model or exhibit has been described by 
photographs that substantially conform to Sec. 1.84, or where the model, 
exhibit or specimen is perishable.
    (c) Where applicant is notified, pursuant to paragraph (a) of this 
section, of the need to arrange for return of a model, exhibit or 
specimen, applicant must arrange for the return within the period set in 
such notice, to avoid disposal of the model, exhibit or specimen by the 
Office. Extensions of time are available under Sec. 1.136, except in the 
case of perishables. Failure to establish that the return of the item 
has been arranged for within the period set or failure to have the item 
removed from Office storage within a reasonable amount of time 
notwithstanding any arrangement for return, will permit the Office to 
dispose of the model, exhibit or specimen.

[69 FR 56542, Sept. 21, 2004]



Sec. 1.95  Copies of exhibits.

    Copies of models or other physical exhibits will not ordinarily be 
furnished by the Office, and any model or exhibit in an application or 
patent shall not be taken from the Office except in the custody of an 
employee of the Office specially authorized by the Director.



Sec. 1.96  Submission of computer program listings.

    (a) General. Descriptions of the operation and general content of 
computer program listings should appear in the description portion of 
the specification. A computer program listing for the purpose of this 
section is defined as a printout that lists in appropriate sequence the 
instructions, routines, and other contents of a program for a computer. 
The program listing may be either in machine or machine-independent 
(object or source) language which will cause a computer to perform a

Sec. 1.104  Nature of examination.

    (a) Examiner's action. (1) On taking up an application for 
examination or a patent in a reexamination proceeding, the examiner 
shall make a thorough study thereof and shall make a thorough 
investigation of the available prior art relating to the subject matter 
of the claimed invention. The examination shall be complete with respect 
both to compliance of the application or patent under reexamination with 
the applicable statutes and rules and to the patentability of the 
invention as claimed, as well as with respect to matters of form, unless 
otherwise indicated.
    (2) The applicant, or in the case of a reexamination proceeding, 
both the patent owner and the requester, will be notified of the 
examiner's action. The reasons for any adverse action or any objection 
or requirement will be stated in an Office action and such information 
or references will be given as may be useful in aiding the applicant, or 
in the case of a reexamination proceeding the patent owner, to judge the 
propriety of continuing the prosecution.
    (3) An international-type search will be made in all national 
applications filed on and after June 1, 1978.
    (4) Any national application may also have an international-type 
search report prepared thereon at the time of the national examination 
on the merits, upon specific written request therefor and payment of the 
international-type search report fee set forth in Sec. 1.21(e). The 
Patent and Trademark Office does not require that a formal report of an 
international-type search be prepared in order to obtain a search fee 
refund in a later filed international application.
    (b) Completeness of examiner's action. The examiner's action will be 
complete as to all matters, except that in appropriate circumstances, 
such as misjoinder of invention, fundamental defects in the application, 
and the like,

[[Page 96]]

the action of the examiner may be limited to such matters before further 
action is made. However, matters of form need not be raised by the 
examiner until a claim is found allowable.
    (c) Rejection of claims. (1) If the invention is not considered 
patentable, or not considered patentable as claimed, the claims, or 
those considered unpatentable will be rejected.
    (2) In rejecting claims for want of novelty or for obviousness, the 
examiner must cite the best references at his or her command. When a 
reference is complex or shows or describes inventions other than that 
claimed by the applicant, the particular part relied on must be 
designated as nearly as practicable. The pertinence of each reference, 
if not apparent, must be clearly explained and each rejected claim 
specified.
    (3) In rejecting claims the examiner may rely upon admissions by the 
applicant, or the patent owner in a reexamination proceeding, as to any 
matter affecting patentability and, insofar as rejections in 
applications are concerned, may also rely upon facts within his or her 
knowledge pursuant to paragraph (d)(2) of this section.
    (4)(i) Subject matter which would otherwise qualify as prior art 
under 35 U.S.C. 102(a)(2) and a claimed invention will be treated as 
commonly owned for purposes of 35 U.S.C. 102(b)(2)(C) if the applicant 
or patent owner provides a statement to the effect that the subject 
matter and the claimed invention, not later than the effective filing 
date of the claimed invention, were owned by the same person or subject 
to an obligation of assignment to the same person.
    (ii) Subject matter which would otherwise qualify as prior art under 
35 U.S.C. 102(a)(2) and a claimed invention will be treated as commonly 
owned for purposes of 35 U.S.C. 102(b)(2)(C) on the basis of a joint 
research agreement under 35 U.S.C. 102(c) if:
    (A) The applicant or patent owner provides a statement to the effect 
that the subject matter was developed and the claimed invention was made 
by or on behalf of one or more parties to a joint research agreement, 
within the meaning of 35 U.S.C. 100(h) and Sec. 1.9(e), that was in 
effect on or before the effective filing date of the claimed invention, 
and the claimed invention was made as a result of activities undertaken 
within the scope of the joint research agreement; and
    (B) The application for patent for the claimed invention discloses 
or is amended to disclose the names of the parties to the joint research 
agreement.
    (5)(i) Subject matter which qualifies as prior art under 35 U.S.C. 
102(e), (f), or (g) in effect prior to March 16, 2013, and a claimed 
invention in an application filed on or after November 29, 1999, or any 
patent issuing thereon, in an application filed before November 29, 
1999, but pending on December 10, 2004, or any patent issuing thereon, 
or in any patent granted on or after December 10, 2004, will be treated 
as commonly owned for purposes of 35 U.S.C. 103(c) in effect prior to 
March 16, 2013, if the applicant or patent owner provides a statement to 
the effect that the subject matter and the claimed invention, at the 
time the claimed invention was made, were owned by the same person or 
subject to an obligation of assignment to the same person.
    (ii) Subject matter which qualifies as prior art under 35 U.S.C. 
102(e), (f), or (g) in effect prior to March 16, 2013, and a claimed 
invention in an application pending on or after December 10, 2004, or in 
any patent granted on or after December 10, 2004, will be treated as 
commonly owned for purposes of 35 U.S.C. 103(c) in effect prior to March 
16, 2013, on the basis of a joint research agreement under 35 U.S.C. 
103(c)(2) in effect prior to March 16, 2013, if:
    (A) The applicant or patent owner provides a statement to the effect 
that the subject matter and the claimed invention were made by or on 
behalf of the parties to a joint research agreement, within the meaning 
of 35 U.S.C. 100(h) and Sec. 1.9(e), which was in effect on or before 
the date the claimed invention was made, and that the claimed invention 
was made as a result of activities undertaken within the scope of the 
joint research agreement; and
    (B) The application for patent for the claimed invention discloses 
or is amended to disclose the names of the

[[Page 97]]

parties to the joint research agreement.
    (6) Patents issued prior to December 10, 2004, from applications 
filed prior to November 29, 1999, are subject to 35 U.S.C. 103(c) in 
effect on November 28, 1999.
    (d) Citation of references. (1) If domestic patents are cited by the 
examiner, their numbers and dates, and the names of the patentees will 
be stated. If domestic patent application publications are cited by the 
examiner, their publication number, publication date, and the names of 
the applicants will be stated. If foreign published applications or 
patents are cited, their nationality or country, numbers and dates, and 
the names of the patentees will be stated, and such other data will be 
furnished as may be necessary to enable the applicant, or in the case of 
a reexamination proceeding, the patent owner, to identify the published 
applications or patents cited. In citing foreign published applications 
or patents, in case only a part of the document is involved, the 
particular pages and sheets containing the parts relied upon will be 
identified. If printed publications are cited, the author (if any), 
title, date, pages or plates, and place of publication, or place where a 
copy can be found, will be given.
    (2) When a rejection in an application is based on facts within the 
personal knowledge of an employee of the Office, the data shall be as 
specific as possible, and the reference must be supported, when called 
for by the applicant, by the affidavit of such employee, and such 
affidavit shall be subject to contradiction or explanation by the 
affidavits of the applicant and other persons.
    (e) Reasons for allowance. If the examiner believes that the record 
of the prosecution as a whole does not make clear his or her reasons for 
allowing a claim or claims, the examiner may set forth such reasoning. 
The reasons shall be incorporated into an Office action rejecting other 
claims of the application or patent under reexamination or be the 
subject of a separate communication to the applicant or patent owner. 
The applicant or patent owner may file a statement commenting on the 
reasons for allowance within such time as may be specified by the 
examiner. Failure by the examiner to respond to any statement commenting 
on reasons for allowance does not give rise to any implication.

Sec. 1.105  Requirements for information.

    (a)(1) In the course of examining or treating a matter in a pending 
or abandoned application, in a patent, or in a reexamination proceeding, 
including a reexamination proceeding ordered as a result of a 
supplemental examination proceeding, the examiner or other Office 
employee may require the submission, from individuals identified under 
Sec. 1.56(c), or any assignee, of such information as may be reasonably 
necessary to properly examine or treat the matter, for example:
    (i) Commercial databases: The existence of any particularly relevant 
commercial database known to any of the inventors that could be searched 
for a particular aspect of the invention.
    (ii) Search: Whether a search of the prior art was made, and if so,

[[Page 98]]

    (viii) Technical information known to applicant. Technical 
information known to applicant concerning the related art, the 
disclosure, the claimed subject matter, other factual information 
pertinent to patentability, or concerning the accuracy of the examiner's 
stated interpretation of such items.
    (2) Requirements for factual information known to applicant may be 
presented in any appropriate manner, for example:
    (i) A requirement for factual information;
    (ii) Interrogatories in the form of specific questions seeking 
applicant's factual knowledge; or
    (iii) Stipulations as to facts with which the applicant may agree or 
disagree.
    (3) Any reply to a requirement for information pursuant to this 
section that states either that the information required to be submitted 
is unknown to or is not readily available to the party or parties from 
which it was requested may be accepted as a complete reply.
    (b) The requirement for information of paragraph (a)(1) of this 
section may be included in an Office action, or sent separately.

Secs. 1.106-1.108  [Reserved]



Sec. 1.109  Effective filing date of a claimed invention under the 
Leahy-Smith America Invents Act.

    (a) The effective filing date for a claimed invention in a patent or 
application for patent, other than in a reissue application or reissued 
patent, is the earliest of:
    (1) The actual filing date of the patent or the application for the 
patent containing a claim to the invention; or
    (2) The filing date of the earliest application for which the patent 
or application is entitled, as to such invention, to a right of priority 
or the benefit of an earlier filing date under 35 U.S.C. 119, 120, 121, 
365, or 386.
    (b) The effective filing date for a claimed invention in a reissue 
application or a reissued patent is determined by deeming the claim to 
the invention to have been contained in the patent for which reissue was 
sought.

Sec. 1.110  Inventorship and ownership of the subject matter of 
individual claims.

    When one or more joint inventors are named in an application or 
patent, the Office may require an applicant or patentee to identify the 
inventorship and ownership or obligation to assign ownership, of each 
claimed invention on its effective filing date (as defined in 
Sec. 1.109) or on its date of invention, as applicable, when necessary 
for purposes of an Office proceeding. The Office may also require an 
applicant or patentee to identify the invention dates of the subject 
matter of each claim when necessary for purposes of an Office 
proceeding.

[78 FR 11058, Feb. 14, 2013]

              Action by Applicant and Further Consideration

    Authority: Secs. 1.111 to 1.113 also issued under 35 U.S.C. 132.



Sec. 1.111  Reply by applicant or patent owner to a non-final 
Office action.

    (a)(1) If the Office action after the first examination (Sec. 1.104) 
is adverse in any respect, the applicant or patent owner, if he or she 
persists in his or her application for a patent or reexamination 
proceeding, must reply and request reconsideration or further 
examination, with or without amendment. See Secs. 1.135 and 1.136 for 
time for reply to avoid abandonment.
    (2) Supplemental replies. (i) A reply that is supplemental to a 
reply that is in compliance with Sec. 1.111(b) will not be entered as a 
matter of right except as provided in paragraph (a)(2)(ii) of this 
section. The Office may enter a supplemental reply if the supplemental 
reply is clearly limited to:
    (A) Cancellation of a claim(s);
    (B) Adoption of the examiner suggestion(s);
    (C) Placement of the application in condition for allowance;

[[Page 99]]

    (D) Reply to an Office requirement made after the first reply was 
filed;
    (E) Correction of informalities (e.g., typographical errors); or
    (F) Simplification of issues for appeal.
    (ii) A supplemental reply will be entered if the supplemental reply 
is filed within the period during which action by the Office is 
suspended under Sec. 1.103(a) or (c).
    (b) In order to be entitled to reconsideration or further 
examination, the applicant or patent owner must reply to the Office 
action. The reply by the applicant or patent owner must be reduced to a 
writing which distinctly and specifically points out the supposed errors 
in the examiner's action and must reply to every ground of objection and 
rejection in the prior Office action. The reply must present arguments 
pointing out the specific distinctions believed to render the claims, 
including any newly presented claims, patentable over any applied 
references. If the reply is with respect to an application, a request 
may be made that objections or requirements as to form not necessary to 
further consideration of the claims be held in abeyance until allowable 
subject matter is indicated. The applicant's or patent owner's reply 
must appear throughout to be a bona fide attempt to advance the 
application or the reexamination proceeding to final action. A general 
allegation that the claims define a patentable invention without 
specifically pointing out how the language of the claims patentably 
distinguishes them from the references does not comply with the 
requirements of this section.
    (c) In amending in reply to a rejection of claims in an application 
or patent under reexamination, the applicant or patent owner must 
clearly point out the patentable novelty which he or she thinks the 
claims present in view of the state of the art disclosed by the 
references cited or the objections made. The applicant or patent owner 
must also show how the amendments avoid such references or objections.

Sec. 1.112  Reconsideration before final action.

    After reply by applicant or patent owner (Sec. 1.111 or Sec. 1.945) 
to a non-final action and any comments by an inter partes reexamination 
requester (Sec. 1.947), the application or the patent under 
reexamination will be reconsidered and again examined. The applicant, or 
in the case of a reexamination proceeding the patent owner and any third 
party requester, will be notified if claims are rejected, objections or 
requirements made, or decisions favorable to patentability are made, in 
the same manner as after the first examination (Sec. 1.104). Applicant 
or patent owner may reply to such Office action in the same manner 
provided in Sec. 1.111 or Sec. 1.945, with or without amendment, unless 
such Office action indicates that it is made final (Sec. 1.113) or an 
appeal (Sec. 41.31 of this title) has been taken (Sec. 1.116), or in an 
inter partes reexamination, that it is an action closing prosecution 
(Sec. 1.949) or a right of appeal notice (Sec. 1.953).

[69 FR 49999, Aug. 12, 2004]



Sec. 1.113  Final rejection or action.

    (a) On the second or any subsequent examination or consideration by 
the examiner the rejection or other action may be made final, whereupon 
applicant's, or for ex parte reexaminations filed under Sec. 1.510, 
patent owner's reply is limited to appeal in the case of rejection of 
any claim (Sec. 41.31 of this title), or to amendment as specified in 
Sec. 1.114 or Sec. 1.116. Petition may be taken to the Director in the 
case of objections or requirements not involved in the rejection of any 
claim (Sec. 1.181). Reply to a final rejection or action must comply 
with Sec. 1.114 or paragraph (c) of this section. For final actions in 
an inter partes reexamination filed under Sec. 1.913, see Sec. 1.953.
    (b) In making such final rejection, the examiner shall repeat or 
state all grounds of rejection then considered applicable to the claims 
in the application, clearly stating the reasons in support thereof.
    (c) Reply to a final rejection or action must include cancellation 
of, or appeal from the rejection of, each rejected claim. If any claim 
stands allowed, the reply to a final rejection or

[[Page 100]]

action must comply with any requirements or objections as to form.

FR 49999, Aug. 12, 2004]



Sec. 1.114  Request for continued examination.

    (a) If prosecution in an application is closed, an applicant may 
request continued examination of the application by filing a submission 
and the fee set forth in Sec. 1.17(e) prior to the earliest of:
    (1) Payment of the issue fee, unless a petition under Sec. 1.313 is 
granted;
    (2) Abandonment of the application; or
    (3) The filing of a notice of appeal to the U.S. Court of Appeals 
for the Federal Circuit under 35 U.S.C. 141, or the commencement of a 
civil action under 35 U.S.C. 145 or 146, unless the appeal or civil 
action is terminated.
    (b) Prosecution in an application is closed as used in this section 
means that the application is under appeal, or that the last Office 
action is a final action (Sec. 1.113), a notice of allowance 
(Sec. 1.311), or an action that otherwise closes prosecution in the 
application.
    (c) A submission as used in this section includes, but is not 
limited to, an information disclosure statement, an amendment to the 
written description, claims, or drawings, new arguments, or new evidence 
in support of patentability. If reply to an Office action under 35 
U.S.C. 132 is outstanding, the submission must meet the reply 
requirements of Sec. 1.111.
    (d) If an applicant timely files a submission and fee set forth in 
Sec. 1.17(e), the Office will withdraw the finality of any Office action 
and the submission will be entered and considered. If an applicant files 
a request for continued examination under this section after appeal, but 
prior to a decision on the appeal, it will be treated as a request to 
withdraw the appeal and to reopen prosecution of the application before 
the examiner. An appeal brief (Sec. 41.37 of this title) or a reply 
brief (Sec. 41.41 of this title), or related papers, will not be 
considered a submission under this section.
    (e) The provisions of this section do not apply to:
    (1) A provisional application;
    (2) An application for a utility or plant patent filed under 35 
U.S.C. 111(a) before June 8, 1995;
    (3) An international application filed under 35 U.S.C. 363 before 
June 8, 1995, or an international application that does not comply with 
35 U.S.C. 371;
    (4) An application for a design patent;
    (5) An international design application; or
    (6) A patent under reexamination.

                               Amendments

    Authority: Secs. 1.115 to 1.127 also issued under 35 U.S.C. 132.



Sec. 1.115  Preliminary amendments.

    (a) A preliminary amendment is an amendment that is received in the 
Office (Sec. 1.6) on or before the mail date of the first Office action 
under Sec. 1.104. The patent application publication may include 
preliminary amendments (Sec. 1.215(a)).
    (1) A preliminary amendment that is present on the filing date of an 
application is part of the original disclosure of the application.
    (2) A preliminary amendment filed after the filing date of the 
application is not part of the original disclosure of the application.
    (b) A preliminary amendment in compliance with Sec. 1.121 will be 
entered unless disapproved by the Director.
    (1) A preliminary amendment seeking cancellation of all the claims 
without presenting any new or substitute claims will be disapproved.
    (2) A preliminary amendment may be disapproved if the preliminary 
amendment unduly interferes with the preparation of a first Office 
action in an application. Factors that will be considered in 
disapproving a preliminary amendment include:
    (i) The state of preparation of a first Office action as of the date 
of receipt (Sec. 1.6) of the preliminary amendment by the Office; and

[[Page 101]]

    (ii) The nature of any changes to the specification or claims that 
would result from entry of the preliminary amendment.
    (3) A preliminary amendment will not be disapproved under (b)(2) of 
this section if it is filed no later than:
    (i) Three months from the filing date of an application under 
Sec. 1.53(b);
    (ii) The filing date of a continued prosecution application under 
Sec. 1.53(d); or
    (iii) Three months from the date the national stage is entered as 
set forth in Sec. 1.491 in an international application.
    (4) The time periods specified in paragraph (b)(3) of this section

application or in an ex parte reexamination filed under Sec. 1.510, or 
an action closing prosecution (Sec. 1.949) in an inter partes 
reexamination filed under Sec. 1.913, but before or on the same date of 
filing an appeal (Sec. 41.31 or Sec. 41.61 of this title):
    (1) An amendment may be made canceling claims or complying with any 
requirement of form expressly set forth in a previous Office action;
    (2) An amendment presenting rejected claims in better form for 
consideration on appeal may be admitted; or
    (3) An amendment touching the merits of the application or patent 
under reexamination may be admitted upon a showing of good and 
sufficient reasons why the amendment is necessary and was not earlier 
presented.
    (c) The admission of, or refusal to admit, any amendment after a 
final rejection, a final action, an action closing prosecution, or any 
related proceedings will not operate to relieve the application or 
reexamination proceeding from its condition as subject to appeal or to 
save the application from abandonment under Sec. 1.135, or the 
reexamination prosecution from termination under Sec. 1.550(d) or 
Sec. 1.957(b) or limitation of further prosecution under Sec. 1.957(c).
    (d)(1) Notwithstanding the provisions of paragraph (b) of this 
section, no amendment other than canceling claims, where such 
cancellation does not affect the scope of any other pending claim in the 
proceeding, can be made in an inter partes reexamination proceeding 
after the right of appeal notice under Sec. 1.953 except as provided in 
Sec. 1.981 or as permitted by Sec. 41.77(b)(1) of this title.
    (2) Notwithstanding the provisions of paragraph (b) of this section, 
an amendment made after a final rejection or other final action 
(Sec. 1.113) in an ex parte reexamination filed under Sec. 1.510, or an 
action closing prosecution (Sec. 1.949) in an inter partes reexamination 
filed under Sec. 1.913 may not cancel claims where such cancellation 
affects the scope of any other pending claim in the reexamination 
proceeding except as provided in Sec. 1.981 or as permitted by 
Sec. 41.77(b)(1) of this title.
    (e) An affidavit or other evidence submitted after a final rejection 
or other final action (Sec. 1.113) in an application or in an ex parte 
reexamination filed under Sec. 1.510, or an action closing prosecution 
(Sec. 1.949) in an inter partes reexamination filed under Sec. 1.913 but 
before or on the same date of filing an appeal (Sec. 41.31 or Sec. 41.61 
of this title), may be admitted upon a showing of good and sufficient 
reasons why the affidavit or other evidence is necessary and was not 
earlier presented.
    (f) Notwithstanding the provisions of paragraph (e) of this section, 
no affidavit or other evidence can be made in an inter partes 
reexamination proceeding after the right of appeal notice under 
Sec. 1.953 except as provided in Sec. 1.981 or as permitted by 
Sec. 41.77(b)(1) of this title.
    (g) After decision on appeal, amendments, affidavits and other 
evidence can only be made as provided in Secs. 1.198 and 1.981, or to 
carry into effect a recommendation under Sec. 41.50(c) of this title.

Secs. 1.117-1.119  [Reserved]



Sec. 1.121  Manner of making amendments in applications.

    (a) Amendments in applications, other than reissue applications. 
Amendments in applications, other than reissue applications, are made by 
filing a paper, in compliance with Sec. 1.52, directing that specified 
amendments be made.
    (b) Specification. Amendments to the specification, other than the 
claims, computer listings (Sec. 1.96) and sequence listings 
(Sec. 1.825), must be made by adding, deleting or replacing a paragraph, 
by replacing a section, or by a substitute specification, in the manner 
specified in this section.
    (1) Amendment to delete, replace, or add a paragraph. Amendments to 
the specification, including amendment to a section heading or the title 
of the invention which are considered for amendment purposes to be an 
amendment of a paragraph, must be made by submitting:
    (i) An instruction, which unambiguously identifies the location, to 
delete one or more paragraphs of the specification, replace a paragraph 
with one or more replacement paragraphs, or add one or more paragraphs;
    (ii) The full text of any replacement paragraph with markings to 
show all the changes relative to the previous version of the paragraph. 
The text of any added subject matter must be shown by underlining the 
added text. The text of any deleted matter must be shown by strike-
through except that double brackets placed before and after the deleted 
characters may be used to show deletion of five or fewer consecutive 
characters. The text of any deleted subject matter must be shown by 
being placed within double brackets if strike-through cannot be easily 
perceived;
    (iii) The full text of any added paragraphs without any underlining; 
and
    (iv) The text of a paragraph to be deleted must not be presented 
with strike-through or placed within double brackets. The instruction to 
delete may identify a paragraph by its paragraph number or include a few 
words from the beginning, and end, of the paragraph, if needed for 
paragraph identification purposes.
    (2) Amendment by replacement section. If the sections of the 
specification contain section headings as provided in Sec. 1.77(b), 
Sec. 1.154(b), or Sec. 1.163(c), amendments to the specification, other 
than the claims, may be made by submitting:
    (i) A reference to the section heading along with an instruction, 
which unambiguously identifies the location, to delete that section of 
the specification and to replace such deleted section with a replacement 
section; and
    (ii) A replacement section with markings to show all changes 
relative to the previous version of the section. The text of any added 
subject matter must be shown by underlining the added text. The text of 
any deleted matter must be shown by strike-through except that double 
brackets placed before and after the deleted characters may be used to 
show deletion of five or fewer consecutive characters. The text of any 
deleted subject matter must be shown by being placed within double 
brackets if strike-through cannot be easily perceived.
    (3) Amendment by substitute specification. The specification, other 
than the claims, may also be amended by submitting:
    (i) An instruction to replace the specification; and
    (ii) A substitute specification in compliance with Secs. 1.125(b) 
and (c).
    (4) Reinstatement of previously deleted paragraph or section. A 
previously deleted paragraph or section may be reinstated only by a 
subsequent amendment adding the previously deleted paragraph or section.
    (5) Presentation in subsequent amendment document. Once a paragraph 
or section is amended in a first amendment document, the paragraph or 
section shall not be re-presented in a subsequent amendment document 
unless it is amended again or a substitute specification is provided.
    (c) Claims. Amendments to a claim must be made by rewriting the 
entire claim with all changes (e.g., additions and deletions) as 
indicated in this subsection, except when the claim is being canceled. 
Each amendment document that includes a change to an existing claim, 
cancellation of an existing claim or addition of a new claim, must

[[Page 103]]

include a complete listing of all claims ever presented, including the 
text of all pending and withdrawn claims, in the application. The claim 
listing, including the text of the claims, in the amendment document 
will serve to replace all prior versions of the claims, in the 
application. In the claim listing, the status of every claim must be 
indicated after its claim number by using one of the following 
identifiers in a parenthetical expression: (Original), (Currently 
amended), (Canceled), (Withdrawn), (Previously presented), (New), and 
(Not entered).
    (1) Claim listing. All of the claims presented in a claim listing 
shall be presented in ascending numerical order. Consecutive claims 
having the same status of ``canceled'' or ``not entered'' may be 
aggregated into one statement (e.g., Claims 1-5 (canceled)). The claim 
listing shall commence on a separate sheet of the amendment document and 
the sheet(s) that contain the text of any part of the claims shall not 
contain any other part of the amendment.
    (2) When claim text with markings is required. All claims being 
currently amended in an amendment paper shall be presented in the claim 
listing, indicate a status of ``currently amended,'' and be submitted 
with markings to indicate the changes that have been made relative to 
the immediate prior version of the claims. The text of any added subject 
matter must be shown by underlining the added text. The text of any 
deleted matter must be shown by strike-through except that double 
brackets placed before and after the deleted characters may be used to 
show deletion of five or fewer consecutive characters. The text of any 
deleted subject matter must be shown by being placed within double 
brackets if strike-through cannot be easily perceived. Only claims 
having the status of ``currently amended,'' or ``withdrawn'' if also 
being amended, shall include markings. If a withdrawn claim is currently 
amended, its status in the claim listing may be identified as 
``withdrawn--currently amended.''
    (3) When claim text in clean version is required. The text of all 
pending claims not being currently amended shall be presented in the 
claim listing in clean version, i.e., without any markings in the 
presentation of text. The presentation of a clean version of any claim 
having the status of ``original,'' ``withdrawn'' or ``previously 
presented'' will constitute an assertion that it has not been changed 
relative to the immediate prior version, except to omit markings that 
may have been present in the immediate prior version of the claims of 
the status of ``withdrawn'' or ``previously presented.'' Any claim added 
by amendment must be indicated with the status of ``new'' and presented 
in clean version, i.e., without any underlining.
    (4) When claim text shall not be presented; canceling a claim. (i) 
No claim text shall be presented for any claim in the claim listing with 
the status of ``canceled'' or ``not entered.''
    (ii) Cancellation of a claim shall be effected by an instruction to 
cancel a particular claim number. Identifying the status of a claim in 
the claim listing as ``canceled'' will constitute an instruction to 
cancel the claim.
    (5) Reinstatement of previously canceled claim. A claim which was 
previously canceled may be reinstated only by adding the claim as a 
``new'' claim with a new claim number.
    (d) Drawings. One or more application drawings shall be amended in 
the following manner: Any changes to an application drawing must be in 
compliance with Sec. 1.84 or, for a nonprovisional international design 
application, in compliance with Secs. 1.84(c) and 1.1026 and must be 
submitted on a replacement sheet of drawings which shall be an 
attachment to the amendment document and, in the top margin, labeled 
``Replacement Sheet.'' Any replacement sheet of drawings shall include 
all of the figures appearing on the immediate prior version of the 
sheet, even if only one figure is amended. Any new sheet of drawings 
containing an additional figure must be labeled in the top margin as 
``New Sheet.'' All changes to the drawings shall be explained, in 
detail, in either the drawing amendment or remarks section of the 
amendment paper.
    (1) A marked-up copy of any amended drawing figure, including 
annotations indicating the changes made, may be included. The marked-up 
copy must be clearly labeled as ``Annotated Sheet''

[[Page 104]]

and must be presented in the amendment or remarks section that explains 
the change to the drawings.
    (2) A marked-up copy of any amended drawing figure, including 
annotations indicating the changes made, must be provided when required 
by the examiner.
    (e) Disclosure consistency. The disclosure must be amended, when 
required by the Office, to correct inaccuracies of description and 
definition, and to secure substantial correspondence between the claims, 
the remainder of the specification, and the drawings.
    (f) No new matter. No amendment may introduce new matter into the 
disclosure of an application.
    (g) Exception for examiner's amendments. Changes to the 
specification, including the claims, of an application made by the 
Office in an examiner's amendment may be made by specific instructions 
to insert or delete subject matter set forth in the examiner's amendment 
by identifying the precise point in the specification or the claim(s) 
where the insertion or deletion is to be made. Compliance with 
paragraphs (b)(1), (b)(2), or (c) of this section is not required.
    (h) Amendment sections. Each section of an amendment document (e.g., 
amendment to the claims, amendment to the specification, replacement 
drawings, and remarks) must begin on a separate sheet.
    (i) Amendments in reissue applications. Any amendment to the 
description and claims in reissue applications must be made in 
accordance with Sec. 1.173.
    (j) Amendments in reexamination proceedings. Any proposed amendment 
to the description and claims in patents involved in reexamination 
proceedings must be made in accordance with Sec. 1.530.
    (k) Amendments in provisional applications. Amendments in 
provisional applications are not usually made. If an amendment is made 
to a provisional application, however, it must comply with the 
provisions of this section. Any amendments to a provisional application 
shall be placed in the provisional application file but may not be 
entered.

80 FR 17963, Apr. 2, 2015]



Secs. 1.122-1.224  [Reserved]



Sec. 1.125  Substitute specification.

    (a) If the number or nature of the amendments or the legibility of 
the application papers renders it difficult to consider the application, 
or to arrange the papers for printing or copying, the Office may require 
the entire specification, including the claims, or any part thereof, be 
rewritten.
    (b) Subject to Sec. 1.312, a substitute specification, excluding the 
claims, may be filed at any point up to payment of the issue fee if it 
is accompanied by a statement that the substitute specification includes 
no new matter.
    (c) A substitute specification submitted under this section must be 
submitted with markings showing all the changes relative to the 
immediate prior version of the specification of record. The text of any 
added subject matter must be shown by underlining the added text. The 
text of any deleted matter must be shown by strike-through except that 
double brackets placed before and after the deleted characters may be 
used to show deletion of five or fewer consecutive characters. The text 
of any deleted subject matter must be shown by being placed within 
double brackets if strike-through cannot be easily perceived. An 
accompanying clean version (without markings) must also be supplied. 
Numbering the paragraphs of the specification of record is not 
considered a change that must be shown pursuant to this paragraph.
    (d) A substitute specification under this section is not permitted 
in a reissue application or in a reexamination proceeding.

[62 FR 53193, Oct. 10, 1997, as amended at 65 FR 54673, Sept. 8, 2000; 
68 FR 38630, June 30, 2003]



Sec. 1.126  Numbering of claims.

    The original numbering of the claims must be preserved throughout 
the prosecution. When claims are canceled the

[[Page 105]]

remaining claims must not be renumbered. When claims are added, they 
must be numbered by the applicant consecutively beginning with the 
number next following the highest numbered claim previously presented 
(whether entered or not). When the application is ready for allowance, 
the examiner, if necessary, will renumber the claims consecutively in 
the order in which they appear or in such order as may have been 
requested by applicant.

[62 FR 53194, Oct. 10, 1997]



Sec. 1.127  Petition from refusal to admit amendment.

    From the refusal of the primary examiner to admit an amendment, in 
whole or in part, a petition will lie to the Director under Sec. 1.181.

                         Transitional Provisions



Sec. 1.129  Transitional procedures for limited examination after final
rejection and restriction practice.

    (a) An applicant in an application, other than for reissue or a 
design patent, that has been pending for at least two years as of June 
8, 1995, taking into account any reference made in such application to 
any earlier filed application under 35 U.S.C. 120, 121 and 365(c), is 
entitled to have a first submission entered and considered on the merits 
after final rejection under the following circumstances: The Office will 
consider such a submission, if the first submission and the fee set 
forth in Sec. 1.17(r) are filed prior to the filing of an appeal brief 
and prior to abandonment of the application. The finality of the final 
rejection is automatically withdrawn upon the timely filing of the 
submission and payment of the fee set forth in Sec. 1.17(r). If a 
subsequent final rejection is made in the application, applicant is 
entitled to have a second submission entered and considered on the 
merits after the subsequent final rejection under the following 
circumstances: The Office will consider such a submission, if the second 
submission and a second fee set forth in Sec. 1.17(r) are filed prior to 
the filing of an appeal brief and prior to abandonment of the 
application. The finality of the subsequent final rejection is 
automatically withdrawn upon the timely filing of the submission and 
payment of the second fee set forth in Sec. 1.17(r). Any submission 
filed after a final rejection made in an application subsequent to the 
fee set forth in Sec. 1.17(r) having been twice paid will be treated as 
set forth in Sec. 1.116. A submission as used in this paragraph 
includes, but is not limited to, an information disclosure statement, an 
amendment to the written description, claims or drawings and a new 
substantive argument or new evidence in support of patentability.
    (b)(1) In an application, other than for reissue or a design patent, 
that has been pending for at least three years as of June 8, 1995; 
taking into account any reference made in the application to any earlier 
filed application under 35 U.S.C. 120, 121, and 365(c), no requirement 
for restriction or for the filing of divisional applications shall be 
made or maintained in the application after June 8, 1995, except where:
    (i) The requirement was first made in the application or any earlier 
filed application under 35 U.S.C. 120, 121 and 365(c) prior to April 8, 
1995;
    (ii) The examiner has not made a requirement for restriction in the 
present or parent application prior to April 8, 1995, due to actions by 
the applicant; or
    (iii) The required fee for examination of each additional invention 
was not paid.
    (2) If the application contains more than one independent and 
distinct invention and a requirement for restriction or for the filing 
of divisional applications cannot be made or maintained pursuant to this 
paragraph, applicant will be so notified and given a time period to:
    (i) Elect the invention or inventions to be searched and examined, 
if no election has been made prior to the notice, and pay the fee set 
forth in Sec. 1.17(s) for each independent and distinct invention 
claimed in the application in excess of one which applicant elects;
    (ii) Confirm an election made prior to the notice and pay the fee 
set forth in Sec. 1.17(s) for each independent and distinct invention 
claimed in the application in addition to the one invention which 
applicant previously elected; or

[[Page 106]]

    (iii) File a petition under this section traversing the requirement. 
If the required petition is filed in a timely manner, the original time 
period for electing and paying the fee set forth in Sec. 1.17(s) will be 
deferred and any decision on the petition affirming or modifying the 
requirement will set a new time period to elect the invention or 
inventions to be searched and examined and to pay the fee set forth in 
Sec. 1.17(s) for each independent and distinct invention claimed in the 
application in excess of one which applicant elects.
    (3) The additional inventions for which the required fee has not 
been paid will be withdrawn from consideration under Sec. 1.142(b). An 
applicant who desires examination of an invention so withdrawn from 
consideration can file a divisional application under 35 U.S.C. 121.
    (c) The provisions of this section shall not be applicable to any 
application filed after June 8, 1995.

[60 FR 20226, Apr. 25, 1995]

                    Affidavits Overcoming Rejections



Sec. 1.130  Affidavit or declaration of attribution or prior public
disclosure under the Leahy-Smith America Invents Act.

    (a) Affidavit or declaration of attribution. When any claim of an 
application or a patent under reexamination is rejected, the applicant 
or patent owner may submit an appropriate affidavit or declaration to 
disqualify a disclosure as prior art by establishing that the disclosure 
was made by the inventor or a joint inventor, or the subject matter 
disclosed was obtained directly or indirectly from the inventor or a 
joint inventor.
    (b) Affidavit or declaration of prior public disclosure. When any 
claim of an application or a patent under reexamination is rejected, the 
applicant or patent owner may submit an appropriate affidavit or 
declaration to disqualify a disclosure as prior art by establishing that 
the subject matter disclosed had, before such disclosure was made or 
before such subject matter was effectively filed, been publicly 
disclosed by the inventor or a joint inventor or another who obtained 
the subject matter disclosed directly or indirectly from the inventor or 
a joint inventor. An affidavit or declaration under this paragraph must 
identify the subject matter publicly disclosed and provide the date such 
subject matter was publicly disclosed by the inventor or a joint 
inventor or another who obtained the subject matter disclosed directly 
or indirectly from the inventor or a joint inventor.
    (1) If the subject matter publicly disclosed on that date was in a 
printed publication, the affidavit or declaration must be accompanied by 
a copy of the printed publication.
    (2) If the subject matter publicly disclosed on that date was not in 
a printed publication, the affidavit or declaration must describe the 
subject matter with sufficient detail and particularity to determine 
what subject matter had been publicly disclosed on that date by the 
inventor or a joint inventor or another who obtained the subject matter 
disclosed directly or indirectly from the inventor or a joint inventor.
    (c) When this section is not available. The provisions of this 
section are not available if the rejection is based upon a disclosure 
made more than one year before the effective filing date of the claimed 
invention. The provisions of this section may not be available if the 
rejection is based upon a U.S. patent or U.S. patent application 
publication of a patented or pending application naming another 
inventor, the patent or pending application claims an invention that is 
the same or substantially the same as the applicant's or patent owner's 
claimed invention, and the affidavit or declaration contends that an 
inventor named in the U.S. patent or U.S. patent application publication 
derived the claimed invention from the inventor or a joint inventor 
named in the application or patent, in which case an applicant or a 
patent owner may file a petition for a derivation proceeding pursuant to 
Sec. 42.401 et seq. of this title.
    (d) Applications and patents to which this section is applicable. 
The provisions of this section apply to any application for patent, and 
to any patent issuing thereon, that contains, or contained at any time:

[[Page 107]]

    (1) A claim to a claimed invention that has an effective filing date 
as defined in Sec. 1.109 that is on or after March 16, 2013; or
    (2) A specific reference under 35 U.S.C. 120, 121, 365(c), or 386(c) 
to any patent or application that contains, or contained at any time, a 
claim to a claimed invention that has an effective filing date as 
defined in Sec. 1.109 that is on or after March 16, 2013.

[78 FR 11058, Feb. 14, 2013, as amended at 80 FR 17963, Apr. 2, 2015]



Sec. 1.131  Affidavit or declaration of prior invention or to disqualify
commonly owned patent or published application as prior art.

    (a) When any claim of an application or a patent under reexamination 
is rejected, the applicant or patent owner may submit an appropriate 
oath or declaration to establish invention of the subject matter of the 
rejected claim prior to the effective date of the reference or activity 
on which the rejection is based. The effective date of a U.S. patent, 
U.S. patent application publication, or international application 
publication under PCT Article 21(2) is the earlier of its publication 
date or the date that it is effective as a reference under 35 U.S.C. 
102(e) as in effect on March 15, 2013. Prior invention may not be 
established under this section in any country other than the United 
States, a NAFTA country, or a WTO member country. Prior invention may 
not be established under this section before December 8, 1993, in a 
NAFTA country other than the United States, or before January 1, 1996, 
in a WTO member country other than a NAFTA country. Prior invention may 
not be established under this section if either:
    (1) The rejection is based upon a U.S. patent or U.S. patent 
application publication of a pending or patented application naming 
another inventor which claims interfering subject matter as defined in 
Sec. 41.203(a) of this chapter, in which case an applicant may suggest 
an interference pursuant to Sec. 41.202(a) of this chapter; or
    (2) The rejection is based upon a statutory bar.
    (b) The showing of facts for an oath or declaration under paragraph 
(a) of this section shall be such, in character and weight, as to 
establish reduction to practice prior to the effective date of the 
reference, or conception of the invention prior to the effective date of 
the reference coupled with due diligence from prior to said date to a 
subsequent reduction to practice or to the filing of the application. 
Original exhibits of drawings or records, or photocopies thereof, must 
accompany and form part of the affidavit or declaration or their absence 
must be satisfactorily explained.
    (c) When any claim of an application or a patent under reexamination 
is rejected under 35 U.S.C. 103 as in effect on March 15, 2013, on a 
U.S. patent or U.S. patent application publication which is not prior 
art under 35 U.S.C. 102(b) as in effect on March 15, 2013, and the 
inventions defined by the claims in the application or patent under 
reexamination and by the claims in the patent or published application 
are not identical but are not patentably distinct, and the inventions 
are owned by the same party, the applicant or owner of the patent under 
reexamination may disqualify the patent or patent application 
publication as prior art. The patent or patent application publication 
can be disqualified as prior art by submission of:
    (1) A terminal disclaimer in accordance with Sec. 1.321(c); and
    (2) An oath or declaration stating that the application or patent 
under reexamination and patent or published application are currently 
owned by the same party, and that the inventor named in the application 
or patent under reexamination is the prior inventor under 35 U.S.C. 104 
as in effect on March 15, 2013.
    (d) The provisions of this section apply to any application for 
patent and to any patent issuing thereon, that contains, or contained at 
any time:
    (1) A claim to an invention that has an effective filing date as 
defined in Sec. 1.109 that is before March 16, 2013; or
    (2) A specific reference under 35 U.S.C. 120, 121, 365(c), or 386(c) 
to any patent or application that contains, or contained at any time, a 
claim to an invention that has an effective filing date as defined in 
Sec. 1.109 that is before March 16, 2013.

[[Page 108]]

    (e) In an application for patent to which the provisions of 
Sec. 1.130 apply, and to any patent issuing thereon, the provisions of 
this section are applicable only with respect to a rejection under 35 
U.S.C. 102(g) as in effect on March 15, 2013.

[78 FR 11058, Feb. 14, 2013, as amended at 78 FR 62405, Oct. 21, 2013; 
80 FR 17963, Apr. 2, 2015]



Sec. 1.132  Affidavits or declarations traversing rejections or 
objections.

    When any claim of an application or a patent under reexamination is 
rejected or objected to, any evidence submitted to traverse the 
rejection or objection on a basis not otherwise provided for must be by 
way of an oath or declaration under this section.

[65 FR 57057, Sept. 20, 2000]

                               Interviews



Sec. 1.133  Interviews.

    (a)(1) Interviews with examiners concerning applications and other 
matters pending before the Office must be conducted on Office premises 
and within Office hours, as the respective examiners may designate. 
Interviews will not be permitted at any other time or place without the 
authority of the Director.
    (2) An interview for the discussion of the patentability of a 
pending application will not occur before the first Office action, 
unless the application is a continuing or substitute application or the 
examiner determines that such an interview would advance prosecution of 
the application.
    (3) The examiner may require that an interview be scheduled in 
advance.
    (b) In every instance where reconsideration is requested in view of 
an interview with an examiner, a complete written statement of the 
reasons presented at the interview as warranting favorable action must 
be filed by the applicant. An interview does not remove the necessity 
for reply to Office actions as specified in Secs. 1.111 and 1.135.

         Time for Reply by Applicant; Abandonment of Application

    Authority: Secs. 1.135 to 1.138 also issued under 35 U.S.C. 133.



Sec. 1.134  Time period for reply to an Office action.

    An Office action will notify the applicant of any non-statutory or 
shortened statutory time period set for reply to an Office action. 
Unless the applicant is notified in writing that a reply is required in 
less than six months, a maximum period of six months is allowed.

[62 FR 53194, Oct. 10, 1997]



Sec. 1.135  Abandonment for failure to reply within time period.

    (a) If an applicant of a patent application fails to reply within 
the time period provided under Sec. 1.134 and Sec. 1.136, the 
application will become abandoned unless an Office action indicates 
otherwise.
    (b) Prosecution of an application to save it from abandonment 
pursuant to paragraph (a) of this section must include such complete and 
proper reply as the condition of the application may require. The 
admission of, or refusal to admit, any amendment after final rejection 
or any amendment not responsive to the last action, or any related 
proceedings, will not operate to save the application from abandonment.
    (c) When reply by the applicant is a bona fide attempt to advance 
the application to final action, and is substantially a complete reply 
to the non-final Office action, but consideration of some matter or 
compliance with some requirement has been inadvertently omitted, 
applicant may be given a new time period for reply under Sec. 1.134 to 
supply the omission.

[62 FR 53194, Oct. 10, 1997]



Sec. 1.136  Extensions of time.

    (a)(1) If an applicant is required to reply within a nonstatutory or 
shortened statutory time period, applicant may extend the time period 
for reply up to the earlier of the expiration of any maximum period set 
by statute or five months after the time period set for reply, if a 
petition for an extension

[[Page 109]]

of time and the fee set in Sec. 1.17(a) are filed, unless:
    (i) Applicant is notified otherwise in an Office action;
    (ii) The reply is a reply brief submitted pursuant to Sec. 41.41 of 
this title;
    (iii) The reply is a request for an oral hearing submitted pursuant 
to Sec. 41.47(a) of this title;
    (iv) The reply is to a decision by the Patent Trial and Appeal Board 
pursuant to Sec. 41.50 or Sec. 41.52 of this chapter or to Sec. 90.3 of 
this chapter; or
    (v) The application is involved in a contested case (Sec. 41.101(a) 
of this title) or a derivation proceeding (Sec. 42.4(b) of this title).
    (2) The date on which the petition and the fee have been filed is 
the date for purposes of determining the period of extension and the 
corresponding amount of the fee. The expiration of the time period is 
determined by the amount of the fee paid. A reply must be filed prior to 
the expiration of the period of extension to avoid abandonment of the 
application (Sec. 1.135), but in no situation may an applicant reply 
later than the maximum time period set by statute, or be granted an 
extension of time under paragraph (b) of this section when the 
provisions of paragraph (a) of this section are available.
    (3) A written request may be submitted in an application that is an 
authorization to treat any concurrent or future reply, requiring a 
petition for an extension of time under this paragraph for its timely 
submission, as incorporating a petition for extension of time for the 
appropriate length of time. An authorization to charge all required 
fees, fees under Sec. 1.17, or all required extension of time fees will 
be treated as a constructive petition for an extension of time in any 
concurrent or future reply requiring a petition for an extension of time 
under this paragraph for its timely submission. Submission of the fee 
set forth in Sec. 1.17(a) will also be treated as a constructive 
petition for an extension of time in any concurrent reply requiring a 
petition for an extension of time under this paragraph for its timely 
submission.
    (b) When a reply cannot be filed within the time period set for such 
reply and the provisions of paragraph (a) of this section are not 
available, the period for reply will be extended only for sufficient 
cause and for a reasonable time specified. Any request for an extension 
of time under this paragraph must be filed on or before the day on which 
such reply is due, but the mere filing of such a request will not effect 
any extension under this paragraph. In no situation can any extension 
carry the date on which reply is due beyond the maximum time period set 
by statute. Any request under this paragraph must be accompanied by the 
petition fee set forth in Sec. 1.17(g).
    (c) If an applicant is notified in a ``Notice of Allowability'' that 
an application is otherwise in condition for allowance, the following 
time periods are not extendable if set in the ``Notice of Allowability'' 
or in an Office action having a mail date on or after the mail date of 
the ``Notice of Allowability'':
    (1) The period for submitting the inventor's oath or declaration;
    (2) The period for submitting formal drawings set under 
Sec. 1.85(c); and
    (3) The period for making a deposit set under Sec. 1.809(c).
    (d) See Sec. 1.550(c) for extensions of time in ex parte 
reexamination proceedings, Sec. 1.956 for extensions of time in inter 
partes reexamination proceedings; Secs. 41.4(a) and 41.121(a)(3) of this 
chapter for extensions of time in contested cases before the Patent 
Trial and Appeal Board; Sec. 42.5(c) of this chapter for extensions of 
time in trials before the Patent Trial and Appeal Board; and Sec. 90.3 
of this chapter for extensions of time to appeal to the U.S. Court of 
Appeals for the Federal Circuit or to commence a civil action.

Sec. 1.137  Revival of abandoned application, or terminated or limited
reexamination prosecution.

    (a) Revival on the basis of unintentional delay. If the delay in 
reply by applicant or patent owner was unintentional, a petition may be 
filed pursuant to this section to revive an abandoned

[[Page 110]]

application or a reexamination prosecution terminated under 
Sec. 1.550(d) or Sec. 1.957(b) or limited under Sec. 1.957(c).
    (b) Petition requirements. A grantable petition pursuant to this 
section must be accompanied by:
    (1) The reply required to the outstanding Office action or notice, 
unless previously filed;
    (2) The petition fee as set forth in Sec. 1.17(m);
    (3) Any terminal disclaimer (and fee as set forth in Sec. 1.20(d)) 
required pursuant to paragraph (d) of this section; and
    (4) A statement that the entire delay in filing the required reply 
from the due date for the reply until the filing of a grantable petition 
pursuant to this section was unintentional. The Director may require 
additional information where there is a question whether the delay was 
unintentional.
    (c) Reply. In an application abandoned under Sec. 1.57(a), the reply 
must include a copy of the specification and any drawings of the 
previously filed application. In an application or patent abandoned for 
failure to pay the issue fee or any portion thereof, the required reply 
must include payment of the issue fee or any outstanding balance. In an 
application abandoned for failure to pay the publication fee, the 
required reply must include payment of the publication fee. In a 
nonprovisional application abandoned for failure to prosecute, the 
required reply may be met by the filing of a continuing application. In 
a nonprovisional utility or plant application filed on or after June 8, 
1995, abandoned after the close of prosecution as defined in 
Sec. 1.114(b), the required reply may also be met by the filing of a 
request for continued examination in compliance with Sec. 1.114.
    (d) Terminal disclaimer. (1) Any petition to revive pursuant to this 
section in a design application must be accompanied by a terminal 
disclaimer and fee as set forth in Sec. 1.321 dedicating to the public a 
terminal part of the term of any patent granted thereon equivalent to 
the period of abandonment of the application. Any petition to revive 
pursuant to this section in either a utility or plant application filed 
before June 8, 1995, must be accompanied by a terminal disclaimer and 
fee as set forth in Sec. 1.321 dedicating to the public a terminal part 
of the term of any patent granted thereon equivalent to the lesser of:
    (i) The period of abandonment of the application; or
    (ii) The period extending beyond twenty years from the date on which 
the application for the patent was filed in the United States or, if the 
application contains a specific reference to an earlier filed 
application(s) under 35 U.S.C. 120, 121, 365(c), or 386(c) from the date 
on which the earliest such application was filed.
    (2) Any terminal disclaimer pursuant to paragraph (d)(1) of this 
section must also apply to any patent granted on a continuing utility or 
plant application filed before June 8, 1995, or a continuing design 
application, that contains a specific reference under 35 U.S.C. 120, 
121, 365(c), or 386(c) to the application for which revival is sought.
    (3) The provisions of paragraph (d)(1) of this section do not apply 
to applications for which revival is sought solely for purposes of 
copendency with a utility or plant application filed on or after June 8, 
1995, to reissue applications, or to reexamination proceedings.
    (e) Request for reconsideration. Any request for reconsideration or 
review of a decision refusing to revive an abandoned application, or a 
terminated or limited reexamination prosecution, upon petition filed 
pursuant to this section, to be considered timely, must be filed within 
two months of the decision refusing to revive or within such time as set 
in the decision. Unless a decision indicates otherwise, this time period 
may be extended under:
    (1) The provisions of Sec. 1.136 for an abandoned application;
    (2) The provisions of Sec. 1.550(c) for a terminated ex parte 
reexamination prosecution, where the ex parte reexamination was filed 
under Sec. 1.510; or
    (3) The provisions of Sec. 1.956 for a terminated inter partes 
reexamination prosecution or an inter partes reexamination limited as to 
further prosecution, where the inter partes reexamination was filed 
under Sec. 1.913.
    (f) Abandonment for failure to notify the Office of a foreign 
filing. A nonprovisional application abandoned pursuant to 35 U.S.C. 
122(b)(2)(B)(iii) for failure

[[Page 111]]

to timely notify the Office of the filing of an application in a foreign 
country or under a multinational treaty that requires publication of 
applications eighteen months after filing, may be revived pursuant to 
this section. The reply requirement of paragraph (c) of this section is 
met by the notification of such filing in a foreign country or under a 
multinational treaty, but the filing of a petition under this section 
will not operate to stay any period for reply that may be running 
against the application.
    (g) Provisional applications. A provisional application, abandoned 
for failure to timely respond to an Office requirement, may be revived 
pursuant to this section. Subject to the provisions of 35 U.S.C. 
119(e)(3) and Sec. 1.7(b), a provisional application will not be 
regarded as pending after twelve months from its filing date under any 
circumstances.

[78 FR 62405, Oct. 21, 2013, as amended at 80 FR 17963, Apr. 2, 2015]



Sec. 1.138  Express abandonment.

    (a) An application may be expressly abandoned by filing a written 
declaration of abandonment identifying the application in the United 
States Patent and Trademark Office. Express abandonment of the 
application may not be recognized by the Office before the date of issue 
or publication unless it is actually received by appropriate officials 
in time to act.
    (b) A written declaration of abandonment must be signed by a party 
authorized under Sec. 1.33(b)(1) or (b)(3) to sign a paper in the 
application, except as otherwise provided in this paragraph. A 
registered attorney or agent, not of record, who acts in a 
representative capacity under the provisions of Sec. 1.34 when filing a 
continuing application, may expressly abandon the prior application as 
of the filing date granted to the continuing application.
    (c) An applicant seeking to abandon an application to avoid 
publication of the application (see Sec. 1.211(a)(1)) must submit a 
declaration of express abandonment by way of a petition under this 
paragraph including the fee set forth in Sec. 1.17(h) in sufficient time 
to permit the appropriate officials to recognize the abandonment and 
remove the application from the publication process. Applicants should 
expect that the petition will not be granted and the application will be 
published in regular course unless such declaration of express 
abandonment and petition are received by the appropriate officials more 
than four weeks prior to the projected date of publication.
    (d) An applicant seeking to abandon an application filed under 35 
U.S.C. 111(a) and Sec. 1.53(b) on or after December 8, 2004, to obtain a 
refund of the search fee and excess claims fee paid in the application, 
must submit a declaration of express abandonment by way of a petition 
under this paragraph before an examination has been made of the 
application. The date indicated on any certificate of mailing or 
transmission under Sec. 1.8 will not be taken into account in 
determining whether a petition under Sec. 1.138(d) was filed before an 
examination has been made of the application. If a request for refund of 
the search fee and excess claims fee paid in the application is not 
filed with the declaration of express abandonment under this paragraph 
or within two months from the date on which the declaration of express 
abandonment under this paragraph was filed, the Office may retain the 
entire search fee and excess claims fee paid in the application. This 
two-month period is not extendable. If a petition and declaration of 
express abandonment under this paragraph are not filed before an 
examination has been made of the application, the Office will not refund 
any part of the search fee and excess claims fee paid in the application 
except as provided in Sec. 1.26.

Sec. 1.139  [Reserved]

          Joinder of Inventions in One Application; Restriction

    Authority: Secs. 1.141 to 1.147 also issued under 35 U.S.C. 121.



Sec. 1.141  Different inventions in one national application.

    (a) Two or more independent and distinct inventions may not be 
claimed in one national application, except that

[[Page 112]]

more than one species of an invention, not to exceed a reasonable 
number, may be specifically claimed in different claims in one national 
application, provided the application also includes an allowable claim 
generic to all the claimed species and all the claims to species in 
excess of one are written in dependent form (Sec. 1.75) or otherwise 
include all the limitations of the generic claim.
    (b) Where claims to all three categories, product, process of 
making, and process of use, are included in a national application, a 
three way requirement for restriction can only be made where the process 
of making is distinct from the product. If the process of making and the 
product are not distinct, the process of using may be joined with the 
claims directed to the product and the process of making the product 
even though a showing of distinctness between the product and process of 
using the product can be made.

[52 FR 20046, May 28, 1987]



Sec. 1.142  Requirement for restriction.

    (a) If two or more independent and distinct inventions are claimed 
in a single application, the examiner in an Office action will require 
the applicant in the reply to that action to elect an invention to which 
the claims will be restricted, this official action being called a 
requirement for restriction (also known as a requirement for division). 
Such requirement will normally be made before any action on the merits; 
however, it may be made at any time before final action.
    (b) Claims to the invention or inventions not elected, if not 
canceled, are nevertheless withdrawn from further consideration by the 
examiner by the election, subject however to reinstatement in the event 
the requirement for restriction is withdrawn or overruled.

[24 FR 10332, Dec. 22, 1959, as amended at 62 FR 53195, Oct. 10, 1997; 
72 FR 46842, Aug. 21, 2007; 74 FR 52691, Oct. 14, 2009]



Sec. 1.143  Reconsideration of requirement.

    If the applicant disagrees with the requirement for restriction, he 
may request reconsideration and withdrawal or modification of the 
requirement, giving the reasons therefor. (See Sec. 1.111.) In 
requesting reconsideration the applicant must indicate a provisional 
election of one invention for prosecution, which invention shall be the 
one elected in the event the requirement becomes final The requirement 
for restriction will be reconsidered on such a request. If the 
requirement is repeated and made final the examiner will at the same 
time act on the claims to the invention elected.



Sec. 1.144  Petition from requirement for restriction.

    After a final requirement for restriction, the applicant, in 
addition to making any reply due on the remainder of the action, may 
petition the Director to review the requirement. Petition may be 
deferred until after final action on or allowance of claims to the 
invention elected, but must be filed not later than appeal. A petition 
will not be considered if reconsideration of the requirement was not 
requested (see Sec. 1.181).

[62 FR 53195, Oct. 10, 1997]



Sec. 1.145  Subsequent presentation of claims for different invention.

    If, after an Office action on an application, the applicant presents 
claims directed to an invention distinct from and independent of the 
invention previously claimed, the applicant will be required to restrict 
the claims to the invention previously claimed if the amendment is 
entered, subject to reconsideration and review as provided in 
Secs. 1.143 and 1.144.

[74 FR 52691, Oct. 14, 2009]



Sec. 1.146  Election of species.

    In the first action on an application containing a generic claim to 
a generic invention (genus) and claims to more than one patentably 
distinct species embraced thereby, the examiner may require the 
applicant in the reply to that action to elect a species of his or her 
invention to which his or her claim will be restricted if no claim to 
the genus is found to be allowable. However, if such application 
contains claims directed to more than a reasonable number of species, 
the examiner

[[Page 113]]

may require restriction of the claims to not more than a reasonable 
number of species before taking further action in the application.

Sec. 1.172  Reissue applicant.

    (a) The reissue applicant is the original patentee, or the current 
patent owner if there has been an assignment. A reissue application must 
be accompanied by the written consent of all assignees, if any, 
currently owning an undivided interest in the patent. All assignees 
consenting to the reissue must establish their ownership in the patent 
by filing in the reissue application a submission in accordance with the

representatives or assigns as the interest may appear.

[77 FR 48821, Aug. 14, 2012]



Sec. 1.173  Reissue specification, drawings, and amendments.

    (a) Contents of a reissue application. An application for reissue 
must contain the entire specification, including the claims, and the 
drawings of the patent. No new matter shall be introduced into the 
application. No reissue patent shall be granted enlarging the scope of 
the claims of the original patent unless applied for within two years 
from the grant of the original patent, pursuant to 35 U.S.C. 251.
    (1) Specification, including claims. The entire specification, 
including the claims, of the patent for which reissue is requested must 
be furnished in the form of a copy of the printed patent, in double 
column format, each page on only one side of a single sheet of paper. If 
an amendment of the reissue application is to be included, it must be 
made pursuant to paragraph (b) of this section. The formal requirements 
for papers making up the reissue application other than those set forth 
in this section are set out in Sec. 1.52. Additionally, a copy of any 
disclaimer (Sec. 1.321), certificate of correction (Secs. 1.322 through 
1.324), or reexamination certificate (Sec. 1.570) issued in the patent 
must be included. (See also Sec. 1.178).
    (2) Drawings. Applicant must submit a clean copy of each drawing 
sheet of the printed patent at the time the reissue application is 
filed. If such copy complies with Sec. 1.84, no further drawings will be 
required. Where a drawing of the reissue application is to include any 
changes relative to the patent being reissued, the changes to the 
drawing must be made in accordance with paragraph (b)(3) of this 
section.

[[Page 116]]

The Office will not transfer the drawings from the patent file to the 
reissue application.
    (b) Making amendments in a reissue application. An amendment in a 
reissue application is made either by physically incorporating the 
changes into the specification when the application is filed, or by a 
separate amendment paper. If amendment is made by incorporation, 
markings pursuant to paragraph (d) of this section must be used. If 
amendment is made by an amendment paper, the paper must direct that 
specified changes be made, as follows:
    (1) Specification other than the claims. Changes to the 
specification, other than to the claims, must be made by submission of 
the entire text of an added or rewritten paragraph, including markings 
pursuant to paragraph (d) of this section, except that an entire 
paragraph may be deleted by a statement deleting the paragraph without 
presentation of the text of the paragraph. The precise point in the 
specification must be identified where any added or rewritten paragraph 
is located. This paragraph applies whether the amendment is submitted on 
paper or compact disc (see Secs. 1.52(e)(1) and 1.821(c), but not for 
discs submitted under Sec. 1.821(e)).
    (2) Claims. An amendment paper must include the entire text of each 
claim being changed by such amendment paper and of each claim being 
added by such amendment paper. For any claim changed by the amendment 
paper, a parenthetical expression ``amended,'' ``twice amended,'' etc., 
should follow the claim number. Each changed patent claim and each added 
claim must include markings pursuant to paragraph (d) of this section, 
except that a patent claim or added claim should be canceled by a 
statement canceling the claim without presentation of the text of the 
claim.
    (3) Drawings. One or more patent drawings shall be amended in the 
following manner: Any changes to a patent drawing must be submitted as a 
replacement sheet of drawings which shall be an attachment to the 
amendment document. Any replacement sheet of drawings must be in 
compliance with Sec. 1.84 and shall include all of the figures appearing 
on the original version of the sheet, even if only one figure is 
amended. Amended figures must be identified as ``Amended,'' and any 
added figure must be identified as ``New.'' In the event that a figure 
is canceled, the figure must be surrounded by brackets and identified as 
``Canceled.'' All changes to the drawing(s) shall be explained, in 
detail, beginning on a separate sheet accompanying the papers including 
the amendment to the drawings.
    (i) A marked-up copy of any amended drawing figure, including 
annotations indicating the changes made, may be included. The marked-up 
copy must be clearly labeled as ``Annotated Marked-up Drawings'' and 
must be presented in the amendment or remarks section that explains the 
change to the drawings.
    (ii) A marked-up copy of any amended drawing figure, including 
annotations indicating the changes made, must be provided when required 
by the examiner.
    (c) Status of claims and support for claim changes. Whenever there 
is an amendment to the claims pursuant to paragraph (b) of this section, 
there must also be supplied, on pages separate from the pages containing 
the changes, the status (i.e., pending or canceled), as of the date of 
the amendment, of all patent claims and of all added claims, and an 
explanation of the support in the disclosure of the patent for the 
changes made to the claims.
    (d) Changes shown by markings. Any changes relative to the patent 
being reissued which are made to the specification, including the 
claims, upon filing, or by an amendment paper in the reissue 
application, must include the following markings:
    (1) The matter to be omitted by reissue must be enclosed in 
brackets; and
    (2) The matter to be added by reissue must be underlined, except for 
amendments submitted on compact discs (Secs. 1.96 and 1.821(c)). Matter 
added by reissue on compact discs must be preceded with ``'' and end 
with ``'' to properly identify the material being added.
    (e) Numbering of patent claims preserved. Patent claims may not be 
renumbered. The numbering of any claim added in the reissue application 
must

[[Page 117]]

follow the number of the highest numbered patent claim.
    (f) Amendment of disclosure may be required. The disclosure must be 
amended, when required by the Office, to correct inaccuracies of 
description and definition, and to secure substantial correspondence 
between the claims, the remainder of the specification, and the 
drawings.
    (g) Amendments made relative to the patent. All amendments must be 
made relative to the patent specification, including the claims, and 
drawings, which are in effect as of the date of filing of the reissue 
application.

Sec. 1.174  [Reserved]



Sec. 1.175  Inventor's oath or declaration for a reissue application.

    (a) The inventor's oath or declaration for a reissue application, in 
addition to complying with the requirements of Sec. 1.63, Sec. 1.64, or 
Sec. 1.67, must also specifically identify at least one error pursuant 
to 35 U.S.C. 251 being relied upon as the basis for reissue and state 
that the applicant believes the original patent to be wholly or partly 
inoperative or invalid by reason of a defective specification or 
drawing, or by reason of the patentee claiming more or less than the 
patentee had the right to claim in the patent.
    (b) If the reissue application seeks to enlarge the scope of the 
claims of the patent (a basis for the reissue is the patentee claiming 
less than the patentee had the right to claim in the patent), the 
inventor's oath or declaration for a reissue application must identify a 
claim that the application seeks to broaden. A claim is a broadened 
claim if the claim is broadened in any respect.
    (c) The inventor, or each individual who is a joint inventor of a 
claimed invention, in a reissue application must execute an oath or 
declaration for the reissue application, except as provided for in 
Sec. 1.64, and except that the inventor's oath or declaration for a 
reissue application may be signed by the assignee of the entire interest 
if:
    (1) The application does not seek to enlarge the scope of the claims 
of the original patent; or
    (2) The application for the original patent was filed under 
Sec. 1.46 by the assignee of the entire interest.
    (d) If errors previously identified in the inventor's oath or 
declaration for a reissue application pursuant to paragraph (a) of this 
section are no longer being relied upon as the basis for reissue, the 
applicant must identify an error being relied upon as the basis for 
reissue.
    (e) The inventor's oath or declaration for a reissue application 
required by paragraph (a) of this section may be submitted under the 
provisions of Sec. 1.53(f), except that the provisions of 
Sec. 1.53(f)(3) do not apply to a reissue application.
    (f)(1) The requirement for the inventor's oath or declaration for a 
continuing reissue application that claims the benefit under 35 U.S.C. 
120, 121, 365(c), or 386(c) in compliance with Sec. 1.78 of an earlier-
filed reissue application may be satisfied by a copy of the inventor's 
oath or declaration from the earlier-filed reissue application, provided 
that:
    (i) The inventor, or each individual who is a joint inventor of a 
claimed invention, in the reissue application executed an inventor's 
oath or declaration for the earlier-filed reissue application, except as 
provided for in Sec. 1.64;
    (ii) The continuing reissue application does not seek to enlarge the 
scope of the claims of the original patent; or
    (iii) The application for the original patent was filed under 
Sec. 1.46 by the assignee of the entire interest.
    (2) If all errors identified in the inventor's oath or declaration 
from the earlier-filed reissue application are no longer being relied 
upon as the basis for reissue, the applicant must identify an error 
being relied upon as the basis for reissue.
    (g) An oath or declaration filed at any time pursuant to 35 U.S.C. 
115(h)(1), will be placed in the file record of the reissue application, 
but may not necessarily be reviewed by the Office.

Sec. 1.176  Examination of reissue.

    (a) A reissue application will be examined in the same manner as a 
non-reissue, non-provisional application, and will be subject to all the 
requirements of the rules related to non-reissue applications. 
Applications for reissue will be acted on by the examiner in advance of 
other applications.
    (b) Restriction between subject matter of the original patent claims 
and previously unclaimed subject matter may be required (restriction 
involving only subject matter of the original patent claims will not be 
required). If restriction is required, the subject matter of the 
original patent claims will be held to be constructively elected unless 
a disclaimer of all the patent claims is filed in the reissue 
application, which disclaimer cannot be withdrawn by applicant.

[65 FR 54676, Sept. 8, 2000]



Sec. 1.177  Issuance of multiple reissue patents.

    (a) The Office may reissue a patent as multiple reissue patents. If 
applicant files more than one application for the reissue of a single 
patent, each such application must contain or be amended to contain in 
the first sentence of the specification a notice stating that more than 
one reissue application has been filed and identifying each of the 
reissue applications by relationship, application number and filing 
date. The Office may correct by certificate of correction under 
Sec. 1.322 any reissue patent resulting from an application to which 
this paragraph applies that does not contain the required notice.
    (b) If applicant files more than one application for the reissue of 
a single patent, each claim of the patent being reissued must be 
presented in each of the reissue applications as an amended, unamended, 
or canceled (shown in brackets) claim, with each such claim bearing the 
same number as in the patent being reissued. The same claim of the 
patent being reissued may not be presented in its original unamended 
form for examination in more than one of such multiple reissue 
applications. The numbering of any added claims in any of the multiple 
reissue applications must follow the number of the highest numbered 
original patent claim.
    (c) If any one of the several reissue applications by itself fails 
to correct an error in the original patent as required by 35 U.S.C. 251 
but is otherwise in condition for allowance, the Office may suspend 
action in the allowable application until all issues are resolved as to 
at least one of the remaining reissue applications. The Office may also 
merge two or more of the multiple reissue applications into a single 
reissue application. No reissue application containing only unamended 
patent claims and not correcting an error in the original patent will be 
passed to issue by itself.

[65 FR 54676, Sept. 8, 2000]



Sec. 1.178  Original patent; continuing duty of applicant.

    (a) The application for reissue of a patent shall constitute an 
offer to surrender that patent, and the surrender shall take effect upon 
reissue of the patent. Until a reissue application is granted, the 
original patent shall remain in effect.
    (b) In any reissue application before the Office, the applicant must 
call to the attention of the Office any prior or concurrent proceedings 
in which the patent (for which reissue is requested) is or was involved, 
such as interferences or trials before the Patent Trial and Appeal 
Board, reissues, reexaminations, or litigations and the results of such 
proceedings (see also Sec. 1.173(a)(1)).

Sec. 1.181  Petition to the Director.

    (a) Petition may be taken to the Director:
    (1) From any action or requirement of any examiner in the ex parte 
prosecution of an application, or in ex parte or inter partes 
prosecution of a reexamination proceeding which is not subject

[[Page 119]]

to appeal to the Patent Trial and Appeal Board or to the court;
    (2) In cases in which a statute or the rules specify that the matter 
is to be determined directly by or reviewed by the Director; and
    (3) To invoke the supervisory authority of the Director in 
appropriate circumstances. For petitions involving action of the Patent 
Trial and Appeal Board, see Sec. 41.3 of this title.
    (b) Any such petition must contain a statement of the facts involved 
and the point or points to be reviewed and the action requested. Briefs 
or memoranda, if any, in support thereof should accompany or be embodied 
in the petition; and where facts are to be proven, the proof in the form 
of affidavits or declarations (and exhibits, if any) must accompany the 
petition.
    (c) When a petition is taken from an action or requirement of an 
examiner in the ex parte prosecution of an application, or in the ex 
parte or inter partes prosecution of a reexamination proceeding, it may 
be required that there have been a proper request for reconsideration 
(Sec. 1.111) and a repeated action by the examiner. The examiner may be 
directed by the Director to furnish a written statement, within a 
specified time, setting forth the reasons for his or her decision upon 
the matters averred in the petition, supplying a copy to the petitioner.
    (d) Where a fee is required for a petition to the Director the 
appropriate section of this part will so indicate. If any required fee 
does not accompany the petition, the petition will be dismissed.
    (e) Oral hearing will not be granted except when considered 
necessary by the Director.
    (f) The mere filing of a petition will not stay any period for reply 
that may be running against the application, nor act as a stay of other 
proceedings. Any petition under this part not filed within two months of 
the mailing date of the action or notice from which relief is requested 
may be dismissed as untimely, except as otherwise provided. This two-
month period is not extendable.
    (g) The Director may delegate to appropriate Patent and Trademark 
Office officials the determination of petitions.

Sec. 1.197  Termination of proceedings.

    (a) Proceedings on an application are considered terminated by the 
dismissal of an appeal or the failure to timely file an appeal to the 
court or a civil action except:
    (1) Where claims stand allowed in an application; or
    (2) Where the nature of the decision requires further action by the 
examiner.
    (b) The date of termination of proceedings on an application is the 
date on which the appeal is dismissed or the date on which the time for 
appeal to the U.S. Court of Appeals for the Federal Circuit or review by 
civil action (Sec. 90.3 of this chapter) expires in the absence of 
further appeal or review. If an appeal to the U.S. Court of Appeals for 
the Federal Circuit or a civil action has been filed, proceedings on an 
application are considered terminated when the appeal or civil action is 
terminated. A civil action is terminated when the time to appeal the 
judgment expires. An appeal to the U.S. Court of Appeals for the Federal 
Circuit, whether from a decision of the Board or a judgment in a civil 
action, is terminated when the mandate is issued by the Court.

Sec. 1.213  Nonpublication request.

    (a) If the invention disclosed in an application has not been and 
will not be the subject of an application filed in another country, or 
under a multilateral international agreement, that requires publication 
of applications eighteen months after filing, the application will not 
be published under 35 U.S.C. 122(b) and Sec. 1.211 provided:
    (1) A request (nonpublication request) is submitted with the 
application upon filing;
    (2) The request states in a conspicuous manner that the application 
is not to be published under 35 U.S.C. 122(b);

application is not to be published under 35 U.S.C. 122(b) is rescinded; 
and
    (3) Be signed in compliance with Sec. 1.33(b).
    (c) If an applicant who has submitted a nonpublication request under 
paragraph (a) of this section subsequently files an application directed 
to the invention disclosed in the application in which the 
nonpublication request was submitted in another country, or under a 
multilateral international agreement, that requires publication of 
applications eighteen months after filing, the applicant must notify the 
Office of such filing within forty-five days after the date of the 
filing of such foreign or international application. The failure to 
timely notify the Office of the filing of such foreign or international 
application shall result in abandonment of the application in which the 
nonpublication request was submitted (35 U.S.C. 122(b)(2)(B)(iii)).



Sec. 1.215  Patent application publication.

    (a) The publication of an application under 35 U.S.C. 122(b) shall 
include a patent application publication. The date of publication shall 
be indicated on the patent application publication. The patent 
application publication will be based upon the specification and 
drawings deposited on the filing date of the application, as well as the 
application data sheet and/or the inventor's oath or declaration. The 
patent application publication may also be based upon amendments to the 
specification (other than the abstract or the claims) that are reflected 
in a substitute specification under Sec. 1.125(b), amendments to the 
abstract under Sec. 1.121(b), amendments to the claims that are 
reflected in a complete claim listing under Sec. 1.121(c), and 
amendments to the drawings under Sec. 1.121(d), provided that such 
substitute specification or amendment is submitted in sufficient time to 
be entered into the Office file wrapper of the application before 
technical preparations for publication of the application have begun. 
Technical preparations for publication of an application generally begin 
four months prior to the projected date of publication. The patent 
application publication of an application that has entered the national 
stage under 35 U.S.C. 371 may also include amendments made during the 
international stage. See paragraph (c) of this section for publication 
of an application based upon a copy of the application submitted via the 
Office electronic filing system.

[[Page 122]]

    (b) The patent application publication will include the name of the 
assignee, person to whom the inventor is under an obligation to assign 
the invention, or person who otherwise shows sufficient proprietary 
interest in the matter if that information is provided in the 
application data sheet in an application filed under Sec. 1.46. Assignee 
information may be included on the patent application publication in 
other applications if the assignee information is provided in an 
application data sheet submitted in sufficient time to be entered into 
the Office file wrapper of the application before technical preparations 
for publication of the application have begun. Providing assignee 
information in the application data sheet does not substitute for 
compliance with any requirement of part 3 of this chapter to have an 
assignment recorded by the Office.
    (c) At applicant's option, the patent application publication will 
be based upon the copy of the application (specification, drawings, and 
the application data sheet and/or the inventor's oath or declaration) as 
amended, provided that applicant supplies such a copy in compliance with 
the Office electronic filing system requirements within one month of the 
mailing date of the first Office communication that includes a 
confirmation number for the application, or fourteen months of the 
earliest filing date for which a benefit is sought under title 35, 
United States Code, whichever is later.
    (d) If the copy of the application submitted pursuant to paragraph 
(c) of this section does not comply with the Office electronic filing 
system requirements, the Office will publish the application as provided 
in paragraph (a) of this section. If, however, the Office has not 
started the publication process, the Office may use an untimely filed 
copy of the application supplied by the applicant under paragraph (c) of 
this section in creating the patent application publication.

    (i) Within one month of the date of mailing of any correspondence 
from the Office, file a copy of such Office correspondence including any 
desired redactions, and a second copy of such Office correspondence 
showing the redacted material in brackets; and

    (3) Each submission under paragraph (d)(1) or (d)(2) of this 
paragraph must also be accompanied by the processing fee set forth in 
Sec. 1.17(i) and a certification that the redactions are limited to the 
elimination of material that is relevant only to the part or description 
of the invention that was not contained in the redacted copy of the 
application submitted for publication.
    (e) The provisions of Sec. 1.8 do not apply to the time periods set 
forth in this section.



Sec. 1.219  Early publication.

    Applications that will be published under Sec. 1.211 may be 
published earlier than as set forth in Sec. 1.211(a) at the request of 
the applicant. Any request for early publication must be accompanied by 
the publication fee set forth in Sec. 1.18(d). If the applicant does not 
submit a copy of the application in compliance with the Office 
electronic filing system requirements pursuant to Sec. 1.215(c), the 
Office will publish the application as provided in Sec. 1.215(a). No 
consideration will be given to requests for publication on a certain 
date, and such requests will be treated as a request for publication as 
soon as possible.



Sec. 1.221  Voluntary publication or republication of patent application
publication.

    (a) Any request for publication of an application filed before, but 
pending on, November 29, 2000, and any request for republication of an

of the application in compliance with the Office electronic filing 
system requirements and be accompanied by the publication fee set forth 
in Sec. 1.18(d) and the processing fee set forth in Sec. 1.17(i). If the 
request does not comply with the requirements of this paragraph or the 
copy of the application does not comply with the Office electronic 
filing system requirements, the Office will not publish the application 
and will refund the publication fee.
    (b) The Office will grant a request for a corrected or revised 
patent application publication other than as provided in paragraph (a) 
of this section only when the Office makes a material mistake which is 
apparent from Office records. Any request for a corrected or revised 
patent application publication other than as provided in paragraph (a) 
of this section must be filed within two months from the date of the 
patent application publication. This period is not extendable.

Sec. 1.291  Protests by the public against pending applications.

    (a) A protest may be filed by a member of the public against a 
pending application, and it will be matched with the application file if 
it adequately identifies the patent application. A protest submitted 
within the time frame of paragraph (b) of this section, which is not 
matched, or not matched in a timely manner to permit review by the 
examiner during prosecution, due to inadequate identification, may not 
be entered and may be returned to the protestor where practical, or, if 
return is not practical, discarded.
    (b) The protest will be entered into the record of the application 
if, in addition to complying with paragraph (c) of this section, the 
protest has been served upon the applicant in accordance with 
Sec. 1.248, or filed with the Office in duplicate in the event service 
is not possible; and, except for paragraph (b)(1) of this section, the 
protest was filed prior to the date the application was published under 
Sec. 1.211, or the date a notice of allowance under Sec. 1.311 was given 
or mailed, whichever occurs first:
    (1) If a protest is accompanied by the written consent of the 
applicant, the protest will be considered if the protest is filed prior 
to the date a notice of allowance under Sec. 1.311 is given or mailed in 
the application.
    (2) A statement must accompany a protest that it is the first 
protest submitted in the application by the real party in interest who 
is submitting the protest; or the protest must comply with paragraph 
(c)(5) of this section. This section does not apply to the first protest 
filed in an application.
    (c) In addition to compliance with paragraphs (a) and (b) of this 
section, a protest must include:
    (1) An information list of the documents, portions of documents, or 
other information being submitted, where each:
    (i) U.S. patent is identified by patent number, first named 
inventor, and issue date;
    (ii) U.S. patent application publication is identified by patent 
application publication number, first named inventor, and publication 
date;
    (iii) Foreign patent or published foreign patent application is 
identified by the country or patent office that issued the patent or 
published the application; an appropriate document number; the 
applicant, patentee, or first named inventor; and the publication date 
indicated on the patent or published application;
    (iv) Non-patent publication is identified by author (if any), title, 
pages being submitted, publication date, and, where available, publisher

    (3) A legible copy of each item identified in the information list, 
other than U.S. patents and U.S. patent application publications;
    (4) An English language translation of any non-English language item 
identified in the information list; and
    (5) If it is a second or subsequent protest by the same real party 
in interest, an explanation as to why the issue(s) raised in the second 
or subsequent protest are significantly different than those raised 
earlier and why the significantly different issue(s) were not presented 
earlier, and a processing fee under Sec. 1.17(i) must be submitted.
    (d) A member of the public filing a protest in an application under 
this section will not receive any communication from the Office relating 
to the protest, other than the return of a self-addressed postcard which 
the member of the public may include with the protest in order to 
receive an acknowledgment by the Office that the protest has

[[Page 127]]

been received. The limited involvement of the member of the public 
filing a protest pursuant to this section ends with the filing of the 
protest, and no further submission on behalf of the protestor will be 
considered, unless the submission is made pursuant to paragraph (c)(5) 
of this section.
    (e) Where a protest raising inequitable conduct issues satisfies the 
provisions of this section for entry, it will be entered into the 
application file, generally without comment on the inequitable conduct 
issues raised in it.
    (f) In the absence of a request by the Office, an applicant need not 
reply to a protest.
    (g) Protests that fail to comply with paragraphs (b) or (c) of this 
section may not be entered, and if not entered, will be returned to the 
protestor, or discarded, at the option of the Office.

Sec. 1.311  Notice of allowance.

    (a) If, on examination, it appears that the applicant is entitled to 
a patent under the law, a notice of allowance will be sent to the 
applicant at the correspondence address indicated in Sec. 1.33. The 
notice of allowance shall specify a sum constituting the issue fee and 
any required publication fee (Sec. 1.211(e)), which issue fee and any 
required publication fee must both be paid within three months from the 
date of mailing of the notice of allowance to avoid abandonment of the 
application. This three-month period is not extendable.
    (b) An authorization to charge the issue fee or other post-allowance 
fees set forth in Sec. 1.18 to a deposit account may be filed in an 
individual application only after mailing of the notice of allowance. 
The submission of either of the following after the mailing of a notice 
of allowance will operate as a request to charge the correct issue fee 
or any publication fee due to any deposit account identified in a 
previously filed authorization to charge such fees:
    (1) An incorrect issue fee or publication fee; or
    (2) A fee transmittal form (or letter) for payment of issue fee or

Sec. 1.312  Amendments after allowance.

    No amendment may be made as a matter of right in an application 
after the mailing of the notice of allowance. Any amendment filed

Sec. 1.313  Withdrawal from issue.

    (a) Applications may be withdrawn from issue for further action at 
the initiative of the Office or upon petition by the applicant. To 
request that the Office withdraw an application from issue, applicant 
must file a petition under this section including the fee set forth in 
Sec. 1.17(h) and a showing of good and sufficient reasons why withdrawal 
of the application from issue is necessary. A petition under this 
section is not required if a request for continued examination under 
Sec. 1.114 is filed prior to payment of the issue fee. If the Office 
withdraws the application from issue, the Office will issue a new notice 
of allowance if the Office again allows the application.
    (b) Once the issue fee has been paid, the Office will not withdraw 
the application from issue at its own initiative for any reason except:
    (1) A mistake on the part of the Office;
    (2) A violation of Sec. 1.56 or illegality in the application;
    (3) Unpatentability of one or more claims; or
    (4) For an interference or derivation proceeding.
    (c) Once the issue fee has been paid, the application will not be 
withdrawn

[[Page 128]]

from issue upon petition by the applicant for any reason except:
    (1) Unpatentability of one of more claims, which petition must be 
accompanied by an unequivocal statement that one or more claims are 
unpatentable, an amendment to such claim or claims, and an explanation 
as to how the amendment causes such claim or claims to be patentable;
    (2) Consideration of a request for continued examination in 
compliance with Sec. 1.114; or
    (3) Express abandonment of the application. Such express abandonment 
may be in favor of a continuing application.
    (d) A petition under this section will not be effective to withdraw 
the application from issue unless it is actually received and granted by 
the appropriate officials before the date of issue. Withdrawal of an 
application from issue after payment of the issue fee may not be 
effective to avoid publication of application information.

patent may disclaim any complete claim or claims in a patent. In like 
manner any patentee may disclaim or dedicate to the public the entire 
term, or any terminal part of the term, of the patent granted. Such

patent granted on that application or any patent subject to the 
reexamination proceeding and the patent or any patent granted on the 
application which formed the basis for the double patenting, and that 
any patent granted on that application or any patent subject to the 
reexamination proceeding shall be enforceable only for and during such 
period that said patent and the patent, or any patent granted on the 
application, which formed the basis for the double patenting are not

Sec. 1.352  [Reserved]

                            Maintenance Fees



Sec. 1.362  Time for payment of maintenance fees.

    (a) Maintenance fees as set forth in Secs. 1.20 (e) through (g) are 
required to be paid in all patents based on applications filed on or 
after December 12, 1980, except as noted in paragraph (b) of this 
section, to maintain a patent in force beyond 4, 8 and 12 years after 
the date of grant.
    (b) Maintenance fees are not required for any plant patents or for 
any design patents. Maintenance fees are not required for a reissue 
patent if the patent being reissued did not require maintenance fees.
    (c) The application filing dates for purposes of payment of 
maintenance fees are as follows:
    (1) For an application not claiming benefit of an earlier 
application, the actual United States filing date of the application.
    (2) For an application claiming benefit of an earlier foreign 
application under 35 U.S.C. 119, the United States filing date of the 
application.
    (3) For a continuing (continuation, division, continuation-in-part) 
application claiming the benefit of a prior patent application under 35 
U.S.C. 120, the actual United States filing date of the continuing 
application.
    (4) For a reissue application, including a continuing reissue 
application claiming the benefit of a reissue application under 35 
U.S.C. 120, United States filing date of the original non-reissue 
application on which the patent reissued is based.
    (5) For an international application which has entered the United 
States as a Designated Office under 35 U.S.C. 371, the international 
filing date granted under Article 11(1) of the Patent Cooperation Treaty 
which is considered to be the United States filing date under 35 U.S.C. 
363.
    (d) Maintenance fees may be paid in patents without surcharge during 
the periods extending respectively from:
    (1) 3 years through 3 years and 6 months after grant for the first 
maintenance fee,
    (2) 7 years through 7 years and 6 months after grant for the second 
maintenance fee, and
    (3) 11 years through 11 years and 6 months after grant for the third 
maintenance fee.
    (e) Maintenance fees may be paid with the surcharge set forth in 
Sec. 1.20(h) during the respective grace periods after:
    (1) 3 years and 6 months and through the day of the 4th anniversary 
of the grant for the first maintenance fee.
    (2) 7 years and 6 months and through the day of the 8th anniversary 
of the grant for the second maintenance fee, and
    (3) 11 years and 6 months and through the day of the 12th 
anniversary of the grant for the third maintenance fee.
    (f) If the last day for paying a maintenance fee without surcharge 
set forth in paragraph (d) of this section, or the last day for paying a 
maintenance fee with surcharge set forth in paragraph (e) of this 
section, falls on a Saturday, Sunday, or a federal holiday within the 
District of Columbia, the maintenance fee and any necessary surcharge 
may be paid under paragraph (d) or paragraph (e) respectively on the 
next succeeding day which is not a Saturday, Sunday, or federal holiday.
    (g) Unless the maintenance fee and any applicable surcharge is paid 
within the time periods set forth in paragraphs (d), (e) or (f) of this 
section, the patent will expire as of the end of the grace period set 
forth in paragraph (e) of this section. A patent which expires for the 
failure to pay the maintenance fee will expire at the end of the same 
date (anniversary date) the patent was granted in the 4th, 8th, or 12th 
year after grant.

[[Page 132]]

    (h) The periods specified in Secs. 1.362 (d) and (e) with respect to 
a reissue application, including a continuing reissue application 
thereof, are counted from the date of grant of the original non-reissue 
application on which the reissued patent is based.

    (a) All notices, receipts, refunds, and other communications 
relating to payment or refund of maintenance fees will be directed to 
the correspondence address used during prosecution of the application as 
indicated in Sec. 1.33(a) unless:
    (1) A fee address for purposes of payment of maintenance fees is set 
forth when submitting the issue fee, or
    (2) A change in the correspondence address for all purposes is filed 
after payment of the issue fee, or
    (3) A fee address or a change in the ``fee address'' is filed for 
purposes of receiving notices, receipts and other correspondence 
relating to the payment of maintenance fees after the payment of the 
issue fee, in which instance, the latest such address will be used.
    (b) An assignment of a patent application or patent does not result 
in a change of the ``correspondence address'' or ``fee address'' for 
maintenance fee purposes.
    (c) A fee address must be an address associated with a Customer 
Number.

Sec. 1.366  Submission of maintenance fees.

    (a) The patentee may pay maintenance fees and any necessary 
surcharges, or any person or organization may pay maintenance fees and 
any necessary surcharges on behalf of a patentee. A maintenance fee 
transmittal letter may be signed by a juristic applicant or patent 
owner. A patentee need not file authorization to enable any person or 
organization to pay maintenance fees and any necessary surcharges on 
behalf of the patentee.
    (b) A maintenance fee and any necessary surcharge submitted for a 
patent must be submitted in the amount due on the date the maintenance 
fee and any necessary surcharge are paid. A maintenance fee or surcharge 
may be paid in the manner set forth in Sec. 1.23 or by an authorization 
to charge a deposit account established pursuant to Sec. 1.25. Payment 
of a maintenance fee and any necessary surcharge or the authorization to 
charge a deposit account must be submitted within the periods set forth 
in Sec. 1.362 (d), (e), or (f). Any payment or authorization of 
maintenance fees and surcharges filed at any other time will not be 
accepted and will not serve as a payment of the maintenance fee except 
insofar as a delayed payment of the maintenance fee is accepted by the 
Director in an expired patent pursuant to a petition filed under 
Sec. 1.378. Any authorization to charge a deposit account must authorize 
the immediate charging of the maintenance fee and any necessary 
surcharge to the deposit account. Payment of less than the required 
amount, payment in a manner other than that set forth in Sec. 1.23, or 
in the filing of an authorization to charge a deposit account having 
insufficient funds will not constitute payment of a maintenance fee or 
surcharge on a patent. The procedures set forth in Sec. 1.8 or Sec. 1.10 
may be utilized in paying maintenance fees and any necessary surcharges.
    (c) In submitting maintenance fees and any necessary surcharges, 
identification of the patents for which maintenance fees are being paid 
must include the patent number, and the application number of the United 
States application for the patent on which the maintenance fee is being 
paid. If the payment includes identification of only the patent number 
(i.e., does not identify the application number of the United States 
application for the patent on which the maintenance fee is being paid), 
the Office may apply the payment to the patent identified by patent 
number in the payment or may return the payment.
    (d) Payment of maintenance fees and any surcharges should identify 
the fee being paid for each patent as to whether it is the 3\1/2\-, 7\1/
2\-, or 11\1/2\-year fee, whether small entity status is being changed 
or claimed, the amount of the maintenance fee and any surcharge

[[Page 133]]

being paid, and any assigned customer number. If the maintenance fee and 
any necessary surcharge is being paid on a reissue patent, the payment 
must identify the reissue patent by reissue patent number and reissue 
application number as required by paragraph (c) of this section and 
should also include the original patent number.
    (e) Maintenance fee payments and surcharge payments relating thereto 
must be submitted separate from any other payments for fees or charges, 
whether submitted in the manner set forth in Sec. 1.23 or by an 
authorization to charge a deposit account. If maintenance fee and 
surcharge payments for more than one patent are submitted together, they 
should be submitted on as few sheets as possible with the patent numbers 
listed in increasing patent number order. If the payment submitted is 
insufficient to cover the maintenance fees and surcharges for all the 
listed patents, the payment will be applied in the order the patents are 
listed, beginning at the top of the listing.
    (f) Notification of any change in status resulting in loss of 
entitlement to small entity status must be filed in a patent prior to 
paying, or at the time of paying, the earliest maintenance fee due after 
the date on which status as a small entity is no longer appropriate. See 
Sec. 1.27(g).
    (g) Maintenance fees and surcharges relating thereto will not be 
refunded except in accordance with Secs. 1.26 and 1.28(a).

Sec. 1.377  Review of decision refusing to accept and record payment
of a maintenance fee filed prior to expiration of patent.

    (a) Any patentee who is dissatisfied with the refusal of the Patent 
and Trademark Office to accept and record a maintenance fee which was 
filed prior to the expiration of the patent may petition the Director to 
accept and record the maintenance fee.
    (b) Any petition under this section must be filed within two months 
of the action complained of, or within such other time as may be set in 
the action complained of, and must be accompanied by the fee set forth 
in Sec. 1.17(g). The petition may include a request that the petition 
fee be refunded if the refusal to accept and record the maintenance fee 
is determined to result from an error by the Patent and Trademark 
Office.
    (c) Any petition filed under this section must comply with the 
requirements of Sec. 1.181(b) and must be signed by an attorney or agent 
registered to practice before the Patent and Trademark Office, or by the 
patentee, the assignee, or other party in interest.

Sec. 1.378  Acceptance of delayed payment of maintenance fee in expired
patent to reinstate patent.

    (a) The Director may accept the payment of any maintenance fee due 
on a patent after expiration of the patent if, upon petition, the delay 
in payment of the maintenance fee is shown to the satisfaction of the 
Director to have been unintentional. If the Director accepts payment of 
the maintenance fee upon petition, the patent shall be considered as not 
having expired, but will be subject to the conditions set forth in 35 
U.S.C. 41(c)(2).
    (b) Any petition to accept an unintentionally delayed payment of a 
maintenance fee must include:
    (1) The required maintenance fee set forth in Sec. 1.20(e) through 
(g);
    (2) The petition fee as set forth in Sec. 1.17(m); and
    (3) A statement that the delay in payment of the maintenance fee was 
unintentional. The Director may require additional information where 
there is a question whether the delay was unintentional.
    (c) Any petition under this section must be signed in compliance 
with Sec. 1.33(b).
    (d) Reconsideration of a decision refusing to accept a delayed 
maintenance fee may be obtained by filing a petition for reconsideration 
within two months of the decision, or such other time as set in the 
decision refusing to accept the delayed payment of the maintenance fee.

[[Page 134]]

    (e) If the delayed payment of the maintenance fee is not accepted, 
the maintenance fee will be refunded following the decision on the 
petition for reconsideration, or after the expiration of the time for 
filing such a petition for reconsideration, if none is filed.

fees.

    (a) Money paid for international application fees, where paid by 
actual mistake or in excess, such as a payment not required by law or 
treaty and its regulations, may be refunded. A mere change of purpose 
after the payment of a fee will not entitle a party to a refund of such 
fee. The Office will not refund amounts of twenty-five dollars or less 
unless a refund is specifically requested and will not notify the payor 
of such amounts. If the payor or party requesting a refund does not 
provide the banking information necessary for making refunds by 
electronic funds transfer, the Office may use the banking information 
provided on the payment instrument to make any refund by electronic 
funds transfer.
    (b) Any request for refund under paragraph (a) of this section must 
be filed within two years from the date the fee was paid. If the Office 
charges a deposit account by an amount other than an amount specifically 
indicated in an authorization under Sec. 1.25(b), any request for refund 
based upon such charge must be filed within two years from the date of 
the deposit account statement indicating such charge and include a copy 
of that deposit account statement. The time periods set forth in this 
paragraph are not extendable.
    (c) Refund of the supplemental search fees will be made if such 
refund is determined to be warranted by the Director or the Director's 
designee acting under PCT Rule 40.2(c).
    (d) The international and search fees will be refunded if no 
international filing date is accorded or if the application is withdrawn 
before transmittal of the record copy to the International Bureau (PCT 
Rules 15.6 and 16.2). The search fee will be refunded if the application 
is withdrawn before transmittal of the search copy to the International 
Searching Authority. The transmittal fee will not be refunded.
    (e) The handling fee (Sec. 1.482(b)) will be refunded (PCT Rule 
57.6) only if:
    (1) The Demand is withdrawn before the Demand has been sent by the 
International Preliminary Examining Authority to the International 
Bureau, or
    (2) The Demand is considered not to have been submitted (PCT Rule 
54.4(a)).

section, be made on the Request (PCT Rule 4.10) in a manner complying

    (b) Whenever the priority of an earlier United States national 
application or international application filed with the United States 
Receiving Office is claimed in an international application, the 
applicant may request in the Request or in a letter of transmittal 
accompanying the international application upon filing with the United 
States Receiving Office or in a separate letter filed in the United 
States Receiving Office not later than 16 months after the priority 
date, that the United States Patent and Trademark Office

[[Page 141]]

prepare a certified copy of the prior application for transmittal to the 
International Bureau (PCT Article 8 and PCT Rule 17). The fee for 
preparing a certified copy is set forth in Sec. 1.19(b)(1).
    (c) If a certified copy of the priority document is not submitted 
together with the international application on filing, or, if the 
priority application was filed in the United States and a request and 
appropriate payment for preparation of such a certified copy do not 
accompany the international application on filing or are not filed 
within 16 months of the priority date, the certified copy of the 
priority document must be furnished by the applicant to the 
International Bureau or to the United States Receiving Office within the

Sec. 1.452  Restoration of right of priority.

    (a) If the international application has an international filing 
date which is later than the expiration of the priority period as 
defined by PCT Rule 2.4 but within two months from the expiration of the 
priority period, the right of priority in the international application 
may be restored upon request if the delay in filing the international 
application within the priority period was unintentional.
    (b) A request to restore the right of priority in an international 
application under paragraph (a) of this section must be filed not later 
than two months from the expiration of the priority period and must 
include:
    (1) A notice under PCT Rule 26bis.1(a) adding the priority claim, if 
the priority claim in respect of the earlier application is not 
contained in the international application;
    (2) The petition fee as set forth in Sec. 1.17(m); and
    (3) A statement that the delay in filing the international 
application within the priority period was unintentional. The Director

delay was unintentional.
    (c) If the applicant makes a request for early publication under PCT 
Article 21(2)(b), any requirement under paragraph (b) of this section 
filed after the technical preparations for international publication 
have been completed by the International Bureau shall be considered as 
not having been submitted in time.

the United States Receiving Office shall prepare and transmit to the 
International Searching Authority, as applicable, a copy of the results 
of the earlier search and any earlier classification as provided under

USPTO has carried out an earlier search or has classified such earlier 
application, the United States Receiving Office shall prepare and 
transmit to the International Searching Authority a copy of the results 
of any such earlier search and earlier classification as provided under 
PCT Rule 23bis.2.
    (c) The United States Receiving Office will not prepare a copy of

                             Representation



Sec. 1.455  Representation in international applications.

    (a) Applicants of international applications may be represented by 
attorneys or agents registered to practice before the United States 
Patent and Trademark Office or by an applicant appointed as a common 
representative (PCT Art. 49, Rules 4.8 and 90 and Sec. 11.9). If 
applicants have not appointed an attorney or agent or one of the 
applicants to represent them, and there is more than one applicant, the 
applicant first named in the request and who is entitled to file in the 
U.S. Receiving Office shall be considered to be the common 
representative of all the applicants. An attorney or agent having the 
right to practice before a national office with which an international 
application is filed and for which the United States is an International 
Searching Authority or International Preliminary Examining Authority may 
be appointed to represent the applicants in the international 
application before that authority. An attorney or agent may appoint an 
associate attorney or agent who shall also then be of record (PCT Rule 
90.1(d)). The appointment of an attorney or agent, or of a common 
representative, revokes any earlier appointment unless otherwise 
indicated (PCT Rule 90.6 (b) and (c)).
    (b) Appointment of an agent, attorney or common representative (PCT 
Rule 4.8) must be effected either in the Request form, signed by 
applicant, in the Demand form, signed by applicant, or in a separate 
power of attorney submitted either to the United States Receiving Office 
or to the International Bureau.
    (c) Powers of attorney and revocations thereof should be submitted 
to the United States Receiving Office until the issuance of the 
international search report.
    (d) The addressee for correspondence will be as indicated in section 
108 of the Administrative Instructions.

    (a) For the purpose of computing time limits under the Treaty, the 
priority date shall be defined as in PCT Art. 2(xi).
    (b) When a claimed priority date is corrected under PCT Rule 
26bis.1(a), or a priority claim is added under PCT Rule 26bis.1(a), 
withdrawn under PCT Rule 90bis.3, or considered not to have been made 
under PCT Rule 26bis.2, the priority date for the purposes of computing 
any non-expired time limits will be the filing date of the earliest 
remaining priority claim under PCT Article 8 of the international 
application, or if none, the international filing date.
    (c) When corrections under PCT Art. 11(2), Art. 14(2) or PCT Rule 
20.2(a) (i) or (iii) are timely submitted, and the date of receipt of

International Searching Authority must be in English, in the form of 
replacement sheets in compliance with PCT Rules 10 and 11, and 
accompanied by a letter that draws attention to the differences between 
the replaced sheets and the replacement sheets. Replacement sheets are 
not required for the deletion of lines of text, the correction of simple 
typographical errors, and one addition or change of not more than five 
words per sheet. These changes may be stated in a letter and, if 
appropriate, the United States Receiving Office will make the deletion 
or transfer the correction to the international application, provided 
that such corrections do not adversely affect the clarity and direct 
reproducibility of the application (PCT Rule 26.4). Amendments that do 
not comply with PCT Rules 10 and 11.1 to 11.13 may not be entered.
    (b) Amendments of claims submitted to the International Bureau shall 
be as prescribed by PCT Rule 46.
    (c) Corrections or additions to the Request of any declarations 
under PCT Rule 4.17 should be submitted to the International Bureau as 
prescribed by PCT Rule 26ter.

                           Unity of Invention



Sec. 1.475  Unity of invention before the International Searching 
Authority, the International Preliminary Examining Authority and during 
the national stage.

    (a) An international and a national stage application shall relate 
to one invention only or to a group of inventions so linked as to form a 
single general inventive concept (``requirement of unity of 
invention''). Where a group of inventions is claimed in an application, 
the requirement of unity of invention shall be fulfilled only when there 
is a technical relationship among those inventions involving one or more 
of the same or corresponding special technical features. The expression 
``special technical features'' shall mean those technical features that 
define a contribution which each of the claimed inventions, considered 
as a whole, makes over the prior art.
    (b) An international or a national stage application containing 
claims to different categories of invention will be considered to have 
unity of invention if the claims are drawn only to one of the following 
combinations of categories:
    (1) A product and a process specially adapted for the manufacture of 
said product; or
    (2) A product and a process of use of said product; or
    (3) A product, a process specially adapted for the manufacture of 
the said product, and a use of the said product; or
    (4) A process and an apparatus or means specifically designed for 
carrying out the said process; or
    (5) A product, a process specially adapted for the manufacture of 
the said

[[Page 144]]

product, and an apparatus or means specifically designed for carrying 
out the said process.
    (c) If an application contains claims to more or less than one of 
the combinations of categories of invention set forth in paragraph (b) 
of this section, unity of invention might not be present.
    (d) If multiple products, processes of manufacture or uses are 
claimed, the first invention of the category first mentioned in the 
claims of the application and the first recited invention of each of the 
other categories related thereto will be considered as the main 
invention in the claims, see PCT Article 17(3)(a) and Sec. 1.476(c).
    (e) The determination whether a group of inventions is so linked as 
to form a single general inventive concept shall be made without regard 
to whether the inventions are claimed in separate claims or as 
alternatives within a single claim.

[58 FR 4345, Jan. 14, 1993]



Sec. 1.476  Determination of unity of invention before the International
Searching Authority.

    (a) Before establishing the international search report, the 
International Searching Authority will determine whether the 
international application complies with the requirement of unity of 
invention as set forth in Sec. 1.475.
    (b) If the International Searching Authority considers that the 
international application does not comply with the requirement of unity 
of invention, it shall inform the applicant accordingly and invite the 
payment of additional fees (note Sec. 1.445 and PCT Art. 17(3)(a) and 
PCT Rule 40). The applicant will be given a time period in accordance 
with PCT Rule 40.3 to pay the additional fees due.
    (c) In the case of non-compliance with unity of invention and where 
no additional fees are paid, the international search will be performed 
on the invention first mentioned (``main invention'') in the claims.
    (d) Lack of unity of invention may be directly evident before 
considering the claims in relation to any prior art, or after taking the 
prior art into consideration, as where a document discovered during the 
search shows the invention claimed in a generic or linking claim lacks 
novelty or is clearly obvious, leaving two or more claims joined thereby 
without a common inventive concept. In such a case the International 
Searching Authority may raise the objection of lack of unity of 
invention.

28, 1987; 58 FR 4346, Jan. 14, 1993]



Sec. 1.477  Protest to lack of unity of invention before the International
Searching Authority.

    (a) If the applicant disagrees with the holding of lack of unity of 
invention by the International Searching Authority, additional fees may 
be paid under protest, accompanied by a request for refund and a 
statement setting forth reasons for disagreement or why the required 
additional fees are considered excessive, or both (PCT Rule 40.2(c)).
    (b) Protest under paragraph (a) of this section will be examined by 
the Director or the Director's designee. In the event that the 
applicant's protest is determined to be justified, the additional fees 
or a portion thereof will be refunded.
    (c) An applicant who desires that a copy of the protest and the 
decision thereon accompany the international search report when 
forwarded to the Designated Offices, may notify the International 
Searching Authority to that effect any time prior to the issuance of the 
international search report. Thereafter, such notification should be 
directed to the International Bureau (PCT Rule 40.2(c)).

Sec. 1.484  Conduct of international preliminary examination.

    (a) An international preliminary examination will be conducted to 
formulate a non-binding opinion as to whether the claimed invention has 
novelty, involves an inventive step (is non-obvious) and is industrially 
applicable.
    (b) International preliminary examination will begin in accordance 
with PCT Rule 69.1.
    (c) No international preliminary examination will be conducted on 
inventions not previously searched by an International Searching 
Authority.
    (d) The International Preliminary Examining Authority will establish 
a written opinion if any defect exists or if the claimed invention lacks 
novelty, inventive step or industrial applicability and will set a non-
extendable time limit in the written opinion for the applicant to reply.
    (e) The written opinion established by the International Searching 
Authority under PCT Rule 43bis.1 shall be considered to be a written 
opinion of the United States International Preliminary Examining 
Authority for the purposes of paragraph (d) of this section.
    (f) The International Preliminary Examining Authority may establish 
further written opinions under paragraph (d) of this section.
    (g) If no written opinion under paragraph (d) of this section is 
necessary, or if no further written opinion under paragraph (f) of this 
section is to be established, or after any written opinion and the reply 
thereto or the expiration of the time limit for reply to such written

    (a) Before establishing any written opinion or the international 
preliminary examination report, the International Preliminary Examining 
Authority will determine whether the international application complies 
with the requirement of unity of invention as set forth in Sec. 1.475.
    (b) If the International Preliminary Examining Authority considers 
that the international application does not comply with the requirement 
of unity of invention, it may:
    (1) Issue a written opinion and/or an international preliminary 
examination report, in respect of the entire international application 
and indicate that unity of invention is lacking and specify the reasons 
therefor without extending an invitation to restrict or pay additional 
fees. No international preliminary examination will be conducted on 
inventions not previously searched by an International Searching 
Authority.
    (2) Invite the applicant to restrict the claims or pay additional 
fees, pointing out the categories of invention found, within a set time 
limit which will not be extended. No international preliminary 
examination will be conducted on inventions not previously searched by 
an International Searching Authority, or
    (3) If applicant fails to restrict the claims or pay additional fees 
within the time limit set for reply, the International Preliminary 
Examining Authority will issue a written opinion and/or establish an 
international preliminary examination report on the main invention and 
shall indicate the relevant facts in the said report. In case of any 
doubt as to which invention is the main invention, the invention first 
mentioned in the claims and previously searched by an International 
Searching Authority shall be considered the main invention.
    (c) Lack of unity of invention may be directly evident before 
considering the claims in relation to any prior art, or after taking the 
prior art into consideration, as where a document discovered during the 
search shows the invention claimed in a generic or linking claim lacks 
novelty or is clearly obvious, leaving two or more claims joined thereby 
without a common inventive concept. In such a case the International 
Preliminary Examining Authority may raise the objection of lack of unity 
of invention.

language, if it was originally filed in another language and if any 
English language translation of the publication of the international 
application previously submitted under 35 U.S.C. 154(d) (Sec. 1.417) is 
not also a translation of the international application as filed (35 
U.S.C. 371(c)(2));
    (ii) The inventor's oath or declaration (35 U.S.C. 371(c)(4) and 
Sec. 1.497), if a declaration of inventorship in compliance with

application is in condition for allowance.
    (iii) An international application in which the basic national fee 
under 35 U.S.C. 41(a)(1)(F) has been paid and for which an application 
data sheet in accordance with Sec. 1.76 has been filed may be treated as

English.
    (g) The documents and fees submitted under paragraphs (b) and (c) of 
this section must be identified as a submission to enter the national 
stage under 35 U.S.C. 371. If the documents and fees contain conflicting 
indications as between an application under 35 U.S.C. 111 and a 
submission to enter the national stage under 35 U.S.C. 371, the 
documents and fees will be treated as a submission to enter the national 
stage under 35 U.S.C. 371.
    (h) An international application becomes abandoned as to the United 
States thirty months from the priority date if the requirements of 
paragraph (b) of this section have not been complied with within thirty

    National stage applications having paid therein the search fee as 
set forth in Sec. 1.492(b)(1) and examination fee as set forth in 
Sec. 1.492(c)(1) may be amended subsequent to the date of commencement

Sec. 1.497  Inventor's oath or declaration under 35 U.S.C. 371(c)(4).

    (a) When an applicant of an international application desires to 
enter the national stage under 35 U.S.C. 371 pursuant to Sec. 1.495, and 
a declaration in compliance with Sec. 1.63 has not been previously 
submitted in the international application under PCT Rule 4.17(iv) 
within the time limits provided for in PCT Rule 26ter.1, the applicant 
must file the inventor's oath or declaration. The inventor, or each 
individual who is a joint inventor of a claimed invention, in an 
application for patent must execute an oath or declaration in accordance 
with the conditions and requirements of Sec. 1.63, except as provided 
for in Sec. 1.64.
    (b) An oath or declaration under Sec. 1.63 will be accepted as 
complying with 35 U.S.C. 371(c)(4) if it complies with the requirements 
of Secs. 1.63(a), (c) and (g). A substitute statement under Sec. 1.64 
will be accepted as complying with 35 U.S.C. 371(c)(4) if it complies 
with the requirements of Secs. 1.64(b)(1), (c) and (e) and identifies 
the person executing the substitute statement. If a newly executed 
inventor's oath or declaration under Sec. 1.63 or substitute statement 
under Sec. 1.64 is not required pursuant to Sec. 1.63(d), submission of 
the copy of the previously executed oath, declaration, or substitute 
statement under Sec. 1.63(d)(1) is required to comply with 35 U.S.C. 
371(c)(4).
    (c) If an oath or declaration under Sec. 1.63, or substitute 
statement under Sec. 1.64, meeting the requirements of Sec. 1.497(b) 
does not also meet the requirements of Sec. 1.63 or Sec. 1.64, an oath, 
declaration, substitute statement, or application data sheet in 
accordance with Sec. 1.76 to comply with Sec. 1.63 or Sec. 1.64 will be 
required.

Sec. 1.499  Unity of invention during the national stage.

    If the examiner finds that a national stage application lacks unity 
of invention under Sec. 1.475, the examiner may in an Office action 
require the applicant in the response to that action to elect the 
invention to which the claims shall be restricted. Such requirement may 
be made before any action on the merits but may be made at any time 
before the final action at the discretion of the examiner. Review of any 
such requirement is provided under Secs. 1.143 and 1.144.

of a patent, file a request for an ex parte reexamination by the Office 
of any claim of the patent on the basis of prior art patents or printed 
publications cited under Sec. 1.501, unless prohibited by 35 U.S.C. 
315(e)(1) or 35 U.S.C. 325(e)(1). The request must be accompanied by the 
fee for requesting reexamination set in Sec. 1.20(c)(1).
    (b) Any request for reexamination must include the following parts:
    (1) A statement pointing out each substantial new question of 
patentability based on prior patents and printed publications.
    (2) An identification of every claim for which reexamination is

applying the cited prior art to every claim for which reexamination is 
requested. For each statement of the patent owner and accompanying 
information submitted pursuant to Sec. 1.501(a)(2) which is relied upon 
in the detailed explanation, the request must explain how that statement 
is being used to determine the proper meaning of a patent claim in 
connection with the prior art applied to that claim and how each 
relevant claim is being interpreted. If appropriate, the party 
requesting reexamination may also point out how claims distinguish over 
cited prior art.
    (3) A copy of every patent or printed publication relied upon or 
referred to in paragraph (b) (1) and (2) of this section accompanied by 
an English language translation of all the necessary and pertinent parts 
of any non-English language patent or printed publication.

    The Director, at any time during the period of enforceability of a 
patent, may determine whether or not a substantial new question of 
patentability is raised by patents or printed publications which have 
been discovered by the Director or which have been brought to the 
Director's attention, even though no request for reexamination has been 
filed in accordance with Sec. 1.510 or Sec. 1.913. The Director may 
initiate ex parte reexamination without a request for reexamination

Office that the Director undertake reexamination on his own initiative 
will not be considered. Any determination to initiate ex parte 
reexamination under this section will become a part of the official file 
of the patent and will be mailed to the patent owner at the address as 
provided for in Sec. 1.33(c).

ex parte reexamination of the patent for resolution of the question. If 
the order for ex parte reexamination resulted from a petition pursuant 
to Sec. 1.515(c), the ex parte reexamination will ordinarily be 
conducted by an examiner other than the examiner responsible for the 
initial determination under Sec. 1.515(a).
    (b) The notice published in the Official Gazette under Sec. 1.11(c) 
will be considered to be constructive notice and ex parte reexamination 
will proceed.

[65 FR 76775, Dec. 7, 2000]



Sec. 1.530  Statement by patent owner in ex parte reexamination; amendment
by patent owner in ex parte or inter partes reexamination; inventorship
change in ex parte or inter partes reexamination.

    (a) Except as provided in Sec. 1.510(e), no statement or other 
response by the patent owner in an ex parte reexamination proceeding 
shall be filed prior to

[[Page 155]]

the determinations made in accordance with Sec. 1.515 or Sec. 1.520. If 
a premature statement or other response is filed by the patent owner, it 
will not be acknowledged or considered in making the determination, and 
it will be returned or discarded (at the Office's option).
    (b) The order for ex parte reexamination will set a period of not 
less than two months from the date of the order within which the patent 
owner may file a statement on the new question of patentability, 
including any proposed amendments the patent owner wishes to make.
    (c) Any statement filed by the patent owner shall clearly point out 
why the subject matter as claimed is not anticipated or rendered obvious 
by the prior art patents or printed publications, either alone or in any 
reasonable combinations. Where the reexamination request was filed by a 
third party requester, any statement filed by the patent owner must be 
served upon the ex parte reexamination requester in accordance with 
Sec. 1.248.
    (d) Making amendments in a reexamination proceeding. A proposed 
amendment in an ex parte or an inter partes reexamination proceeding is 
made by filing a paper directing that proposed specified changes be made 
to the patent specification, including the claims, or to the drawings. 
An amendment paper directing that proposed specified changes be made in 
a reexamination proceeding may be submitted as an accompaniment to a 
request filed by the patent owner in accordance with Sec. 1.510(e), as 
part of a patent owner statement in accordance with paragraph (b) of 
this section, or, where permitted, during the prosecution of the 
reexamination proceeding pursuant to Sec. 1.550(a) or Sec. 1.937.
    (1) Specification other than the claims. Changes to the 
specification, other than to the claims, must be made by submission of 
the entire text of an added or rewritten paragraph including markings 
pursuant to paragraph (f) of this section, except that an entire 
paragraph may be deleted by a statement deleting the paragraph, without 
presentation of the text of the paragraph. The precise point in the 
specification must be identified where any added or rewritten paragraph 
is located. This paragraph applies whether the amendment is submitted on 
paper or compact disc (see Secs. 1.96 and 1.825).
    (2) Claims. An amendment paper must include the entire text of each 
patent claim which is being proposed to be changed by such amendment 
paper and of each new claim being proposed to be added by such amendment 
paper. For any claim changed by the amendment paper, a parenthetical 
expression ``amended,'' ``twice amended,'' etc., should follow the claim 
number. Each patent claim proposed to be changed and each proposed added 
claim must include markings pursuant to paragraph (f) of this section, 
except that a patent claim or proposed added claim should be canceled by 
a statement canceling the claim, without presentation of the text of the 
claim.
    (3) Drawings. Any change to the patent drawings must be submitted as 
a sketch on a separate paper showing the proposed changes in red for 
approval by the examiner. Upon approval of the changes by the examiner, 
only new sheets of drawings including the changes and in compliance with 
Sec. 1.84 must be filed. Amended figures must be identified as 
``Amended,'' and any added figure must be identified as ``New.'' In the 
event a figure is canceled, the figure must be surrounded by brackets 
and identified as ``Canceled.''
    (4) The formal requirements for papers making up the reexamination 
proceeding other than those set forth in this section are set out in 
Sec. 1.52.
    (e) Status of claims and support for claim changes. Whenever there 
is an amendment to the claims pursuant to paragraph (d) of this section, 
there must also be supplied, on pages separate from the pages containing 
the changes, the status (i.e., pending or canceled), as of the date of 
the amendment, of all patent claims and of all added claims, and an 
explanation of the support in the disclosure of the patent for the 
changes to the claims made by the amendment paper.
    (f) Changes shown by markings. Any changes relative to the patent 
being reexamined which are made to the specification, including the 
claims, must include the following markings:

[[Page 156]]

    (1) The matter to be omitted by the reexamination proceeding must be 
enclosed in brackets; and
    (2) The matter to be added by the reexamination proceeding must be 
underlined.
    (g) Numbering of patent claims preserved. Patent claims may not be 
renumbered. The numbering of any claims added in the reexamination 
proceeding must follow the number of the highest numbered patent claim.
    (h) Amendment of disclosure may be required. The disclosure must be 
amended, when required by the Office, to correct inaccuracies of 
description and definition, and to secure substantial correspondence 
between the claims, the remainder of the specification, and the 
drawings.
    (i) Amendments made relative to patent. All amendments must be made 
relative to the patent specification, including the claims, and 
drawings, which are in effect as of the date of filing the request for 
reexamination.
    (j) No enlargement of claim scope. No amendment may enlarge the 
scope of the claims of the patent or introduce new matter. No amendment 
may be proposed for entry in an expired patent. Moreover, no amendment, 
other than the cancellation of claims, will be incorporated into the 
patent by a certificate issued after the expiration of the patent.
    (k) Amendments not effective until certificate. Although the Office 
actions will treat proposed amendments as though they have been entered, 
the proposed amendments will not be effective until the reexamination 
certificate is issued and published.
    (l) Correction of inventorship in an ex parte or inter partes 
reexamination proceeding.  (1) When it appears in a patent being 
reexamined that the correct inventor or inventors were not named, the 
Director may, on petition of all the parties set forth in 
Sec. 1.324(b)(1) and (b)(2), including the assignees, and satisfactory 
proof of the facts and payment of the fee set forth in Sec. 1.20(b), or 
on order of a court before which such matter is called in question, 
include in the reexamination certificate to be issued under Sec. 1.570 
or Sec. 1.997 an amendment naming only the actual inventor or inventors. 
The petition must be submitted as part of the reexamination proceeding 
and must satisfy the requirements of Sec. 1.324.
    (2) Notwithstanding paragraph (l)(1) of this section, if a petition 
to correct inventorship satisfying the requirements of Sec. 1.324 is 
filed in a reexamination proceeding, and the reexamination proceeding is 
concluded other than by a reexamination certificate under Sec. 1.570 or 
Sec. 1.997, a certificate of correction indicating the change of 
inventorship stated in the petition will be issued upon request by the 
patentee.

16, 2007; 77 FR 48825, Aug. 14, 2012]



Sec. 1.535  Reply by third party requester in ex parte reexamination.

    A reply to the patent owner's statement under Sec. 1.530 may be 
filed by the ex parte reexamination requester within two months from the 
date of service of the patent owner's statement. Any reply by the ex 
parte requester must be served upon the patent owner in accordance with 
Sec. 1.248. If the patent owner does not file a statement under 
Sec. 1.530, no reply or other submission from the ex parte reexamination 
requester will be considered.

[65 FR 76776, Dec. 7, 2000]



Sec. 1.540  Consideration of responses in ex parte reexamination.

    The failure to timely file or serve the documents set forth in 
Sec. 1.530 or in Sec. 1.535 may result in their being refused 
consideration. No submissions other than the statement pursuant to 
Sec. 1.530 and the reply by the ex parte reexamination requester 
pursuant to Sec. 1.535 will be considered prior to examination.

[65 FR 76776, Dec. 7, 2000]



Sec. 1.550  Conduct of ex parte reexamination proceedings.

    (a) All ex parte reexamination proceedings, including any appeals to 
the Board of Patent Appeals and Interferences, will be conducted with 
special dispatch within the Office. After issuance of the ex parte 
reexamination order and expiration of the time for

[[Page 157]]

submitting any responses, the examination will be conducted in 
accordance with Secs. 1.104 through 1.116 and will result in the 
issuance of an ex parte reexamination certificate under Sec. 1.570.
    (b) The patent owner in an ex parte reexamination proceeding will be 
given at least thirty days to respond to any Office action. In response 
to any rejection, such response may include further statements and/or 
proposed amendments or new claims to place the patent in a condition 
where all claims, if amended as proposed, would be patentable.
    (c) The time for taking any action by a patent owner in an ex parte 
reexamination proceeding may be extended as provided in this paragraph.
    (1) Any request for such an extension must specify the requested 
period of extension and be accompanied by the petition fee set forth in 
Sec. 1.17(g).
    (2) Any request for an extension in a third party requested ex parte 
reexamination must be filed on or before the day on which action by the 
patent owner is due, and the mere filing of such a request for extension 
will not effect the extension. A request for an extension in a third 
party requested ex parte reexamination will not be granted in the 
absence of sufficient cause or for more than a reasonable time.
    (3) Any request for an extension in a patent owner requested or 
Director ordered ex parte reexamination for up to two months from the 
time period set in the Office action must be filed no later than two 
months from the expiration of the time period set in the Office action. 
A request for an extension in a patent owner requested or Director 
ordered ex parte reexamination for more than two months from the time 
period set in the Office action must be filed on or before the day on 
which action by the patent owner is due, and the mere filing of a 
request for an extension for more than two months from the time period 
set in the Office action will not effect the extension. The time for 
taking action in a patent owner requested or Director ordered ex parte 
reexamination will not be extended for more than two months from the 
time period set in the Office action in the absence of sufficient cause 
or for more than a reasonable time.
    (4) The reply or other action must in any event be filed prior to 
the expiration of the period of extension, but in no situation may a 
reply or other action be filed later than the maximum time period set by 
statute.
    (5) See Sec. 90.3(c) of this title for extensions of time for filing 
a notice of appeal to the U.S. Court of Appeals for the Federal Circuit 
or for commencing a civil action.
    (d) If the patent owner fails to file a timely and appropriate 
response to any Office action or any written statement of an interview 
required under Sec. 1.560(b), the prosecution in the ex parte 
reexamination proceeding will be a terminated prosecution, and the 
Director will proceed to issue and publish a certificate concluding the 
reexamination proceeding under Sec. 1.570 in accordance with the last 
action of the Office.
    (e) If a response by the patent owner is not timely filed in the 
Office, a petition may be filed pursuant to Sec. 1.137 to revive a 
reexamination prosecution terminated under paragraph (d) of this section 
if the delay in response was unintentional.
    (f) The reexamination requester will be sent copies of Office 
actions issued during the ex parte reexamination proceeding. After 
filing of a request for ex parte reexamination by a third party 
requester, any document filed by either the patent owner or the third 
party requester must be served on the other party in the reexamination 
proceeding in the manner provided by Sec. 1.248. The document must 
reflect service or the document may be refused consideration by the 
Office.
    (g) The active participation of the ex parte reexamination requester 
ends with the reply pursuant to Sec. 1.535, and no further submissions 
on behalf of the reexamination requester will be acknowledged or 
considered. Further, no submissions on behalf of any third parties will 
be acknowledged or considered unless such submissions are:
    (1) in accordance with Sec. 1.510 or Sec. 1.535; or
    (2) entered in the patent file prior to the date of the order for ex 
parte reexamination pursuant to Sec. 1.525.
    (h) Submissions by third parties, filed after the date of the order 
for ex parte reexamination pursuant to Sec. 1.525,

[[Page 158]]

must meet the requirements of and will be treated in accordance with 
Sec. 1.501(a).
    (i) A petition in an ex parte reexamination proceeding must be 
accompanied by the fee set forth in Sec. 1.20(c)(6), except for 
petitions under paragraph (c) of this section to extend the period for 
response by a patent owner, petitions under paragraph (e) of this 
section to accept a delayed response by a patent owner, petitions under 
Sec. 1.78 to accept an unintentionally delayed benefit claim, and 
petitions under Sec. 1.530(l) for correction of inventorship in a 
reexamination proceeding.

Sec. 1.552  Scope of reexamination in ex parte reexamination proceedings.

    (a) Claims in an ex parte reexamination proceeding will be examined 
on the basis of patents or printed publications and, with respect to 
subject matter added or deleted in the reexamination proceeding, on the 
basis of the requirements of 35 U.S.C. 112.
    (b) Claims in an ex parte reexamination proceeding will not be 
permitted to enlarge the scope of the claims of the patent.
    (c) Issues other than those indicated in paragraphs (a) and (b) of 
this section will not be resolved in a reexamination proceeding. If such 
issues are raised by the patent owner or third party requester during a 
reexamination proceeding, the existence of such issues will be noted by 
the examiner in the next Office action, in which case the patent owner 
may consider the advisability of filing a reissue application to have 
such issues considered and resolved.
    (d) Any statement of the patent owner and any accompanying 
information submitted pursuant to Sec. 1.501(a)(2) which is of record in 
the patent being reexamined (which includes any reexamination files for 
the patent) may be used after a reexamination proceeding has been 
ordered to determine the proper meaning of a patent claim when applying 
patents or printed publications.

[65 FR 76776, Dec. 7, 2000, as amended at 77 FR 46627, Aug. 6, 2012]



Sec. 1.555  Information material to patentability in ex parte
reexamination and inter partes reexamination proceedings.

    (a) A patent by its very nature is affected with a public interest. 
The public interest is best served, and the most effective reexamination 
occurs when, at the time a reexamination proceeding is being conducted, 
the Office is aware of and evaluates the teachings of all information 
material to patentability in a reexamination proceeding. Each individual 
associated with the patent owner in a reexamination proceeding has a 
duty of candor and good faith in dealing with the Office, which includes 
a duty to disclose to the Office all information known to that 
individual to be material to patentability in a reexamination 
proceeding. The individuals who have a duty to disclose to the Office 
all information known to them to be material to patentability in a 
reexamination proceeding are the patent owner, each attorney or agent 
who represents the patent owner, and every other individual who is 
substantively involved on behalf of the patent owner in a reexamination 
proceeding. The duty to disclose the information exists with respect to 
each claim pending in the reexamination proceeding until the claim is 
cancelled. Information material to the patentability of a cancelled 
claim need not be submitted if the information is not material to 
patentability of any claim remaining under consideration in the 
reexamination proceeding. The duty to disclose all information known to 
be material to patentability in a reexamination proceeding is deemed to 
be satisfied if all information known to be material to patentability of 
any claim in the patent after issuance of the reexamination certificate 
was cited by the Office or submitted to the Office in an information 
disclosure statement. However, the duties of candor, good faith, and 
disclosure have not been complied with if any fraud on the Office was 
practiced or attempted or the duty of disclosure was violated through

[[Page 159]]

bad faith or intentional misconduct by, or on behalf of, the patent 
owner in the reexamination proceeding. Any information disclosure 
statement must be filed with the items listed in Sec. 1.98(a) as applied 
to individuals associated with the patent owner in a reexamination 
proceeding, and should be filed within two months of the date of the 
order for reexamination, or as soon thereafter as possible.
    (b) Under this section, information is material to patentability in 
a reexamination proceeding when it is not cumulative to information of 
record or being made of record in the reexamination proceeding, and
    (1) It is a patent or printed publication that establishes, by 
itself or in combination with other patents or printed publications, a 
prima facie case of unpatentability of a claim; or
    (2) It refutes, or is inconsistent with, a position the patent owner 
takes in:
    (i) Opposing an argument of unpatentability relied on by the Office, 
or
    (ii) Asserting an argument of patentability.

A prima facie case of unpatentability of a claim pending in a 
reexamination proceeding is established when the information compels a 
conclusion that a claim is unpatentable under the preponderance of 
evidence, burden-of-proof standard, giving each term in the claim its 
broadest reasonable construction consistent with the specification, and 
before any consideration is given to evidence which may be submitted in 
an attempt to establish a contrary conclusion of patentability.
    (c) The responsibility for compliance with this section rests upon 
the individuals designated in paragraph (a) of this section and no 
evaluation will be made by the Office in the reexamination proceeding as 
to compliance with this section. If questions of compliance with this 
section are raised by the patent owner or the third party requester 
during a reexamination proceeding, they will be noted as unresolved 
questions in accordance with Sec. 1.552(c).

[57 FR 2036, Jan. 17, 1992, as amended at 65 FR 76776, Dec. 7, 2000]



Sec. 1.560  Interviews in ex parte reexamination proceedings.

    (a) Interviews in ex parte reexamination proceedings pending before 
the Office between examiners and the owners of such patents or their 
attorneys or agents of record must be conducted in the Office at such 
times, within Office hours, as the respective examiners may designate. 
Interviews will not be permitted at any other time or place without the 
authority of the Director. Interviews for the discussion of the 
patentability of claims in patents involved in ex parte reexamination 
proceedings will not be conducted prior to the first official action. 
Interviews should be arranged in advance. Requests that reexamination 
requesters participate in interviews with examiners will not be granted.
    (b) In every instance of an interview with an examiner in an ex 
parte reexamination proceeding, a complete written statement of the 
reasons presented at the interview as warranting favorable action must 
be filed by the patent owner. An interview does not remove the necessity 
for response to Office actions as specified in Sec. 1.111. Patent 
owner's response to an outstanding Office action after the interview 
does not remove the necessity for filing the written statement. The 
written statement must be filed as a separate part of a response to an 
Office action outstanding at the time of the interview, or as a separate 
paper within one month from the date of the interview, whichever is 
later.

[65 FR 76777, Dec. 7, 2000]



Sec. 1.565  Concurrent office proceedings which include an ex parte
reexamination proceeding.

    (a) In an ex parte reexamination proceeding before the Office, the 
patent owner must inform the Office of any prior or concurrent 
proceedings in which the patent is or was involved such as 
interferences, reissues, ex parte reexaminations, inter partes 
reexaminations, or litigation and the results of such proceedings. See 
Sec. 1.985 for notification of prior or concurrent proceedings in an 
inter partes reexamination proceeding.

[[Page 160]]

    (b) If a patent in the process of ex parte reexamination is or 
becomes involved in litigation, the Director shall determine whether or 
not to suspend the reexamination. See Sec. 1.987 for inter partes 
reexamination proceedings.
    (c) If ex parte reexamination is ordered while a prior ex parte 
reexamination proceeding is pending and prosecution in the prior ex 
parte reexamination proceeding has not been terminated, the ex parte 
reexamination proceedings will usually be merged and result in the 
issuance and publication of a single certificate under Sec. 1.570. For 
merger of inter partes reexamination proceedings, see Sec. 1.989(a). For 
merger of ex parte reexamination and inter partes reexamination 
proceedings, see Sec. 1.989(b).
    (d) If a reissue application and an ex parte reexamination 
proceeding on which an order pursuant to Sec. 1.525 has been mailed are 
pending concurrently on a patent, a decision will usually be made to 
merge the two proceedings or to suspend one of the two proceedings. 
Where merger of a reissue application and an ex parte reexamination 
proceeding is ordered, the merged examination will be conducted in 
accordance with Secs. 1.171 through 1.179, and the patent owner will be 
required to place and maintain the same claims in the reissue 
application and the ex parte reexamination proceeding during the 
pendency of the merged proceeding. The examiner's actions and responses 
by the patent owner in a merged proceeding will apply to both the 
reissue application and the ex parte reexamination proceeding and will 
be physically entered into both files. Any ex parte reexamination 
proceeding merged with a reissue application shall be concluded by the 
grant of the reissued patent. For merger of a reissue application and an 
inter partes reexamination, see Sec. 1.991.
    (e) If a patent in the process of ex parte reexamination is or 
becomes involved in an interference, the Director may suspend the 
reexamination or the interference. The Director will not consider a 
request to suspend an interference unless a motion (Sec. 41.121(a)(3) of 
this title) to suspend the interference has been presented to, and 
denied by, an administrative patent judge, and the request is filed 
within ten (10) days of a decision by an administrative patent judge 
denying the motion for suspension or such other time as the 
administrative patent judge may set. For concurrent inter partes 
reexamination and interference of a patent, see Sec. 1.993.

FR 18905, Apr. 16, 2007]

                   Ex Parte Reexamination Certificate



Sec. 1.570  Issuance and publication of ex parte reexamination certificate
concludes ex parte reexamination proceeding.

    (a) To conclude an ex parte reexamination proceeding, the Director 
will issue and publish an ex parte reexamination certificate in 
accordance with 35 U.S.C. 307 setting forth the results of the ex parte 
reexamination proceeding and the content of the patent following the ex 
parte reexamination proceeding.
    (b) An ex parte reexamination certificate will be issued and 
published in each patent in which an ex parte reexamination proceeding 
has been ordered under Sec. 1.525 and has not been merged with any inter 
partes reexamination proceeding pursuant to Sec. 1.989(a). Any statutory 
disclaimer filed by the patent owner will be made part of the ex parte 
reexamination certificate.
    (c) The ex parte reexamination certificate will be mailed on the day 
of its date to the patent owner at the address as provided for in 
Sec. 1.33(c). A copy of the ex parte reexamination certificate will also 
be mailed to the requester of the ex parte reexamination proceeding.
    (d) If an ex parte reexamination certificate has been issued and 
published which cancels all of the claims of the patent, no further 
Office proceedings will be conducted with that patent or any reissue 
applications or any reexamination requests relating thereto.
    (e) If the ex parte reexamination proceeding is terminated by the 
grant of a reissued patent as provided in Sec. 1.565(d), the reissued 
patent will constitute the ex parte reexamination certificate required 
by this section and 35 U.S.C. 307.
    (f) A notice of the issuance of each ex parte reexamination 
certificate under this section will be published in the Official Gazette 
on its date of issuance.

    Source: 77 FR 48851, Aug. 14, 2012, unless otherwise noted.



Sec. 1.601  Filing of papers in supplemental examination.

    (a) A request for supplemental examination of a patent must be filed 
by the owner(s) of the entire right, title, and interest in the patent.
    (b) Any party other than the patent owner (i.e., any third party) is 
prohibited from filing papers or otherwise participating in any manner 
in a supplemental examination proceeding.
    (c) A request for supplemental examination of a patent may be filed 
at any time during the period of enforceability of the patent.



Sec. 1.605  Items of information.

    (a) Each request for supplemental examination may include no more 
than twelve items of information believed to be relevant to the patent. 
More than one request for supplemental examination of the same patent 
may be filed at any time during the period of enforceability of the 
patent.
    (b) An item of information includes a document submitted as part of 
the request that contains information, believed to be relevant to the 
patent, that the patent owner requests the Office to consider, 
reconsider, or correct. If the information to be considered, 
reconsidered, or corrected is not, at least in part, contained within or 
based on any document submitted as part of the request, the discussion 
within the body of the request relative to the information will be 
considered as an item of information.
    (c) An item of information must be in writing in accordance with 
Sec. 1.2. To be considered, any audio or video recording must be 
submitted in the form of a written transcript.

patent is raised by any of the items of information presented in the 
request. The determination will generally be limited to a review of the 
item(s) of information identified in the request as applied to the 
identified claim(s) of the patent. The determination will be based on 
the claims in effect at the time of the determination and will become a 
part of the official record of the patent.
    (b) The Office may hold in abeyance action on any petition or other 
paper filed in a supplemental examination proceeding until after the

supplemental examination proceeding or of the identified post-patent 
Office proceeding(s).
    (e) Interviews are prohibited in a supplemental examination 
proceeding.
    (f) No amendment may be filed in a supplemental examination 
proceeding.
    (g) If the Office becomes aware, during the course of supplemental 
examination or of any reexamination ordered under 35 U.S.C. 257 as a 
result of the supplemental examination proceeding, that a material fraud 
on the Office may have been committed in connection with the patent 
requested to be examined, the supplemental examination proceeding or any 
reexamination proceeding ordered under 35 U.S.C. 257 will continue, and 
the matter will be referred to the U.S. Attorney General in accordance 
with 35 U.S.C. 257(e).



Sec. 1.625  Conclusion of supplemental examination; publication of
supplemental examination certificate; procedure after conclusion.

    (a) A supplemental examination proceeding will conclude with the 
electronic issuance of a supplemental examination certificate. The 
supplemental examination certificate will indicate the result of the 
determination whether any of the items of information presented in the 
request raised a substantial new question of patentability.
    (b) If the supplemental examination certificate states that a 
substantial new question of patentability is raised by one or more items 
of information in the request, ex parte reexamination of the patent will 
be ordered under 35 U.S.C. 257. Upon the conclusion of the ex parte 
reexamination proceeding, an ex parte reexamination certificate, which 
will include a statement specifying that ex parte reexamination was 
ordered under 35 U.S.C. 257, will be published. The electronically 
issued supplemental examination certificate will remain as part of the 
public record of the patent.
    (c) If the supplemental examination certificate indicates that no 
substantial new question of patentability is raised by any of the items 
of information in the request, and ex parte reexamination is not ordered 
under 35 U.S.C. 257, the electronically issued supplemental examination 
certificate will be published in due course. The fee for reexamination 
ordered as a result of supplemental examination, as set forth in 
Sec. 1.20(k)(2), will be refunded in accordance with Sec. 1.26(c).
    (d) Any ex parte reexamination ordered under 35 U.S.C. 257 will be 
conducted in accordance with Secs. 1.530 through 1.570, which govern ex 
parte reexamination, except that:
    (1) The patent owner will not have the right to file a statement 
pursuant to Sec. 1.530, and the order will not set a time period within 
which to file such a statement;
    (2) Reexamination of any claim of the patent may be conducted on the 
basis of any item of information as set forth in Sec. 1.605, and is not 
limited to patents and printed publications or to subject matter that 
has been added or deleted during the reexamination proceeding, 
notwithstanding Sec. 1.552(a);
    (3) Issues in addition to those raised by patents and printed 
publications, and by subject matter added or deleted during a 
reexamination proceeding, may be considered and resolved, 
notwithstanding Sec. 1.552(c); and

           Adjustment of Patent Term Due to Examination Delay



Sec. 1.701  Extension of patent term due to examination delay under the
Uruguay Round Agreements Act (original applications, other than designs, 
filed on or 
          after June 8, 1995, and before May 29, 2000).

    (a) A patent, other than for designs, issued on an application filed 
on or

[[Page 164]]

after June 8, 1995, is entitled to extension of the patent term if the 
issuance of the patent was delayed due to:
    (1) Interference or derivation proceedings under 35 U.S.C. 135(a); 
and/or
    (2) The application being placed under a secrecy order under 35 
U.S.C. 181; and/or
    (3) Appellate review by the Patent Trial and Appeal Board or by a 
Federal court under 35 U.S.C. 141 or 145, if the patent was issued 
pursuant to a decision in the review reversing an adverse determination 
of patentability and if the patent is not subject to a terminal 
disclaimer due to the issuance of another patent claiming subject matter 
that is not patentably distinct from that under appellate review. If an 
application is remanded by a panel of the Patent Trial and Appeal Board 
and the remand is the last action by a panel of the Patent Trial and 
Appeal Board prior to the mailing of a notice of allowance under 35 
U.S.C. 151 in the application, the remand shall be considered a decision 
in the review reversing an adverse determination of patentability as 
that phrase is used in 35 U.S.C. 154(b)(2) as amended by section 532(a) 
of the Uruguay Round Agreements Act, Public Law 103-465, 108 Stat. 4809, 
4983-85 (1994), and a final decision in favor of the applicant under 
paragraph (c)(3) of this section. A remand by a panel of the Patent 
Trial and Appeal Board shall not be considered a decision in the review 
reversing an adverse determination of patentability as provided in this 
paragraph if there is filed a request for continued examination under 35 
U.S.C. 132(b) that was not first preceded by the mailing, after such 
remand, of at least one of an action under 35 U.S.C. 132 or a notice of 
allowance under 35 U.S.C. 151.
    (b) The term of a patent entitled to extension under paragraph (a) 
of this section shall be extended for the sum of the periods of delay 
calculated under paragraphs (c)(1), (c)(2), (c)(3) and (d) of this 
section, to the extent that these periods are not overlapping, up to a 
maximum of five years. The extension will run from the expiration date 
of the patent.
    (c)(1) The period of delay under paragraph (a)(1) of this section 
for an application is the sum of the following periods, to the extent 
that the periods are not overlapping:
    (i) With respect to each interference or derivation proceeding in 
which the application was involved, the number of days, if any, in the 
period beginning on the date the interference or derivation proceeding 
was instituted to involve the application in the interference or 
derivation proceeding and ending on the date that the interference or 
derivation proceeding was terminated with respect to the application; 
and
    (ii) The number of days, if any, in the period beginning on the date 
prosecution in the application was suspended by the Patent and Trademark 
Office due to interference or derivation proceedings under 35 U.S.C. 
135(a) not involving the application and ending on the date of the 
termination of the suspension.
    (2) The period of delay under paragraph (a)(2) of this section for 
an application is the sum of the following periods, to the extent that 
the periods are not overlapping:
    (i) The number of days, if any, the application was maintained in a 
sealed condition under 35 U.S.C. 181;
    (ii) The number of days, if any, in the period beginning on the date 
of mailing of an examiner's answer under Sec. 41.39 of this title in the 
application under secrecy order and ending on the date the secrecy order 
and any renewal thereof was removed;
    (iii) The number of days, if any, in the period beginning on the 
date applicant was notified that an interference or derivation 
proceeding would be instituted but for the secrecy order and ending on 
the date the secrecy order and any renewal thereof was removed; and
    (iv) The number of days, if any, in the period beginning on the date 
of notification under Sec. 5.3(c) and ending on the date of mailing of 
the notice of allowance under Sec. 1.311.
    (3) The period of delay under paragraph (a)(3) of this section is 
the sum of the number of days, if any, in the period beginning on the 
date on which an appeal to the Patent Trial and Appeal Board was filed 
under 35 U.S.C. 134 and ending on the date of a final decision in favor 
of the applicant by the Patent

[[Page 165]]

Trial and Appeal Board or by a Federal court in an appeal under 35 
U.S.C. 141 or a civil action under 35 U.S.C. 145.
    (d) The period of delay set forth in paragraph (c)(3) shall be 
reduced by:
    (1) Any time during the period of appellate review that occurred 
before three years from the filing date of the first national 
application for patent presented for examination; and
    (2) Any time during the period of appellate review, as determined by 
the Director, during which the applicant for patent did not act with due 
diligence. In determining the due diligence of an applicant, the 
Director may examine the facts and circumstances of the applicant's 
actions during the period of appellate review to determine whether the 
applicant exhibited that degree of timeliness as may reasonably be 
expected from, and which is ordinarily exercised by, a person during a 
period of appellate review.
    (e) The provisions of this section apply only to original patents, 
except for design patents, issued on applications filed on or after June 
8, 1995, and before May 29, 2000.

Sec. 1.702  Grounds for adjustment of patent term due to examination 
delay under the Patent Term Guarantee Act of 1999 (original applications,
other than designs, filed on or after May 29, 2000).

    (a) Failure to take certain actions within specified time frames. 
Subject to the provisions of 35 U.S.C. 154(b) and this subpart, the term 
of an original patent shall be adjusted if the issuance of the patent 
was delayed due to the failure of the Office to:
    (1) Mail at least one of a notification under 35 U.S.C. 132 or a 
notice of allowance under 35 U.S.C. 151 not later than fourteen months 
after the date on which the application was filed under 35 U.S.C. 111(a) 
or the date the national stage commenced under 35 U.S.C. 371(b) or (f) 
in an international application;
    (2) Respond to a reply under 35 U.S.C. 132 or to an appeal taken 
under 35 U.S.C. 134 not later than four months after the date on which 
the reply was filed or the appeal was taken;
    (3) Act on an application not later than four months after the date 
of a decision by the Patent Trial and Appeal Board under 35 U.S.C. 134 
or 135 or a decision by a Federal court under 35 U.S.C. 141, 145, or 146 
where at least one allowable claim remains in the application; or
    (4) Issue a patent not later than four months after the date on 
which the issue fee was paid under 35 U.S.C. 151 and all outstanding 
requirements were satisfied.
    (b) Three-year pendency. Subject to the provisions of 35 U.S.C. 
154(b) and this subpart, the term of an original patent shall be 
adjusted if the issuance of the patent was delayed due to the failure of 
the Office to issue a patent within three years after the date on which 
the application was filed under 35 U.S.C. 111(a) or the national stage 
commenced under 35 U.S.C. 371(b) or (f) in an international application, 
but not including:
    (1) Any time consumed by continued examination of the application 
under 35 U.S.C. 132(b);
    (2) Any time consumed by an interference or derivation proceeding 
under 35 U.S.C. 135(a);
    (3) Any time consumed by the imposition of a secrecy order under 35 
U.S.C. 181;
    (4) Any time consumed by review by the Patent Trial and Appeal Board 
or a Federal court; or
    (5) Any delay in the processing of the application by the Office 
that was requested by the applicant.
    (c) Delays caused by interference and derivation proceedings. 
Subject to the provisions of 35 U.S.C. 154(b) and this subpart, the term 
of an original patent shall be adjusted if the issuance of the patent 
was delayed due to interference or derivation proceedings under 35 
U.S.C. 135(a).
    (d) Delays caused by secrecy order. Subject to the provisions of 35 
U.S.C. 154(b) and this subpart, the term of an original patent shall be 
adjusted if the issuance of the patent was delayed due to the 
application being placed under a secrecy order under 35 U.S.C. 181.
    (e) Delays caused by successful appellate review. Subject to the 
provisions of 35 U.S.C. 154(b) and this subpart, the

[[Page 166]]

term of an original patent shall be adjusted if the issuance of the 
patent was delayed due to review by the Patent Trial and Appeal Board 
under 35 U.S.C. 134 or by a Federal court under 35 U.S.C. 141 or 145, if 
the patent was issued under a decision in the review reversing an 
adverse determination of patentability. If an application is remanded by 
a panel of the Patent Trial and Appeal Board and the remand is the last 
action by a panel of the Patent Trial and Appeal Board prior to the 
mailing of a notice of allowance under 35 U.S.C. 151 in the application, 
the remand shall be considered a decision by the Patent Trial and Appeal 
Board as that phrase is used in 35 U.S.C. 154(b)(1)(A)(iii), a decision 
in the review reversing an adverse determination of patentability as 
that phrase is used in 35 U.S.C. 154(b)(1)(C)(iii), and a final decision 
in favor of the applicant under Sec. 1.703(e). A remand by a panel of 
the Patent Trial and Appeal Board shall not be considered a decision in 
the review reversing an adverse determination of patentability as 
provided in this paragraph if there is filed a request for continued 
examination under 35 U.S.C. 132(b) that was not first preceded by the 
mailing, after such remand, of at least one of an action under 35 U.S.C. 
132 or a notice of allowance under 35 U.S.C. 151.
    (f) The provisions of this section and Secs. 1.703 through 1.705 
apply only to original applications, except applications for a design 
patent, filed on or after May 29, 2000, and patents issued on such 
applications.

Sec. 1.750  Determination of eligibility for extension of patent term.

    A determination as to whether a patent is eligible for extension may 
be made by the Director solely on the basis of the representations 
contained in the application for extension filed in compliance with 
Sec. 1.740 or Sec. 1.790. This determination may be delegated to 
appropriate Patent and Trademark Office officials and may be made at any 
time before the certificate of extension is issued. The Director or 
other appropriate officials may require from applicant further 
information or make such independent inquiries as desired before a final 
determination is made on whether a patent is eligible for extension. In 
an application for extension filed in compliance with Sec. 1.740, a 
notice will be mailed to applicant containing the determination as to 
the eligibility of the patent for extension and the period of time of 
the extension, if any. This notice shall constitute the final 
determination as to the eligibility and any period of extension of

[[Page 176]]

the patent. A single request for reconsideration of a final 
determination may be made if filed by the applicant within such time as 
may be set in the notice of final determination or, if no time is set,

an interim extension is granted and notice of the extension will be 
published in the Official Gazette of the United States Patent and 
Trademark Office. The notice will be recorded in the official file of 
the patent and will be considered as part of the original patent. In no 
event will the interim extensions granted under this section be longer

eligible.

[65 FR 54680, Sept. 8, 2000]



Sec. 1.765  Duty of disclosure in patent term extension proceedings.

    (a) A duty of candor and good faith toward the Patent and Trademark 
Office and the Secretary of Health and Human Services or the Secretary 
of Agriculture rests on the patent owner or its agent, on each attorney 
or agent who represents the patent owner and on every other individual 
who is substantively involved on behalf of the patent owner in a patent 
term extension proceeding. All such individuals who are aware, or become 
aware, of material information adverse to a determination of entitlement 
to the extension sought, which has not been previously made of record in 
the patent term extension proceeding must bring such information to the 
attention of the Office or the Secretary, as appropriate, in accordance 
with paragraph (b) of this section, as soon as it is practical to do so 
after the individual becomes aware of the information. Information is 
material where there is a substantial likelihood that the Office or the 
Secretary would consider it important in determinations to be made in 
the patent term extension proceeding.
    (b) Disclosures pursuant to this section must be accompanied by a 
copy of each written document which is being disclosed. The disclosure 
must be made to the Office or the Secretary, as appropriate, unless the 
disclosure is material to determinations to be made by both the Office 
and the Secretary, in which case duplicate copies, certified as such, 
must be filed in the Office and with the Secretary. Disclosures pursuant 
to this section may be made to the Office or the Secretary, as 
appropriate, through an attorney or agent having responsibility on 
behalf of the patent owner or its agent for the patent term extension 
proceeding or through a patent owner acting on his or her own behalf. 
Disclosure to such an attorney, agent or patent owner shall satisfy the 
duty of any other individual. Such an attorney, agent or patent owner 
has no duty to transmit information which is not material to the 
determination of entitlement to the extension sought.
    (c) No patent will be determined eligible for extension and no 
extension will be issued if it is determined that fraud on the Office or 
the Secretary was practiced or attempted or the duty of disclosure was 
violated through bad faith or gross negligence in connection with the 
patent term extension proceeding. If it is established by clear and 
convincing evidence that any fraud was practiced or attempted on the 
Office or the Secretary in connection with the patent term extension 
proceeding or that there was any violation of the duty of disclosure 
through bad faith or gross negligence in connection with the patent term 
extension proceeding, a final determination will be made pursuant to 
Sec. 1.750 that the patent is not eligible for extension.

[[Page 177]]

    (d) The duty of disclosure pursuant to this section rests on the 
individuals identified in paragraph (a) of this section and no 
submission on behalf of third parties, in the form of protests or 
otherwise, will be considered by the Office. Any such submissions by 
third parties to the Office will be returned to the party making the 
submission, or otherwise disposed of, without consideration by the 
Office.

Sec. 1.770  Express withdrawal of application for extension of patent
term.

    An application for extension of patent term may be expressly 
withdrawn before a determination is made pursuant to Sec. 1.750 by 
filing in the Office, in duplicate, a written declaration of withdrawal 
signed by the owner of record of the patent or its agent. An application 
may not be expressly withdrawn after the date permitted for reply to the 
final determination on the application. An express withdrawal pursuant 
to this section is effective when acknowledged in writing by the Office. 
The filing of an express withdrawal pursuant to this section and its 
acceptance by the Office does not entitle applicant to a refund of the 
filing fee (Sec. 1.20(j)) or any portion thereof.

Act and ending on the date such application was approved under such 
section.
    (d) The term of the patent as extended for an animal drug will be 
determined by--
    (1) Subtracting from the number of days determined by the Secretary 
of Health and Human Services to be in the regulatory review period:
    (i) The number of days in the periods of paragraphs (c)(1) and 
(c)(2) of this section that were on and before the date on which the 
patent issued;
    (ii) The number of days in the periods of paragraphs (c)(1) and 
(c)(2) of this section during which it is determined under 35 U.S.C. 
156(d)(2)(B) by the Secretary of Health and Human Services that 
applicant did not act with due diligence;
    (iii) One-half the number of days remaining in the period defined by 
paragraph (c)(1) of this section after that period is reduced in 
accordance with paragraphs (d)(1) (i) and (ii) of this section; half 
days will be ignored for purposes of subtraction;
    (2) By adding the number of days determined in paragraph (d)(1) of 
this section to the original term of the patent as shortened by any 
terminal disclaimer;
    (3) By adding 14 years to the date of approval of the application 
under section 512 of the Federal Food, Drug, and Cosmetic Act;
    (4) By comparing the dates for the ends of the periods obtained 
pursuant to paragraphs (d)(2) and (d)(3) of this section with each other 
and selecting the earlier date;
    (5) If the original patent was issued after November 16, 1988, by--
    (i) Adding 5 years to the original expiration date of the patent or 
any earlier date set by terminal disclaimer; and
    (ii) Comparing the dates obtained pursuant to paragraphs (d)(4) and 
(d)(5)(i) of this section with each other and selecting the earlier 
date;
    (6) If the original patent was issued before November 16, 1988, and
    (i) If no major health or environmental effects test on the drug was 
initiated and no request was submitted for an exemption under subsection 
(j) of section 512 of the Federal Food, Drug, and Cosmetic Act before 
November 16, 1988, by--

Sec. 1.780  Certificate or order of extension of patent term.

    If a determination is made pursuant to Sec. 1.750 that a patent is 
eligible for extension and that the term of the patent is to be 
extended, a certificate of extension, under seal, or an order granting 
interim extension under 35 U.S.C.

[[Page 183]]

156(d)(5), will be issued to the applicant for the extension of the 
patent term. Such certificate or order will be recorded in the official 
file of the patent and will be considered as part of the original 
patent. Notification of the issuance of the certificate or order of 
extension will be published in the Official Gazette of the United States 
Patent and Trademark Office. Notification of the issuance of the order 
granting an interim extension under 35 U.S.C. 156(d)(5), including the 
identity of the product currently under regulatory review, will be 
published in the Official Gazette of the United States Patent and 
Trademark Office and in the Federal Register. No certificate of, or 
order granting, an extension will be issued if the term of the patent 
cannot be extended, even though the patent is otherwise determined to be 
eligible for extension. In such situations, the final determination made 
pursuant to Sec. 1.750 will indicate that no certificate or order will 
issue.

[65 FR 54680, Sept. 8, 2000]



Sec. 1.785  Multiple applications for extension of term of the same
patent or of different patents for the same regulatory review period
for a product.

    (a) Only one patent may be extended for a regulatory review period 
for any product (Sec. 1.720(h)). If more than one application for 
extension of the same patent is filed, the certificate of extension of 
patent term, if appropriate, will be issued based upon the first filed 
application for extension.
    (b) If more than one application for extension is filed by a single 
applicant which seeks the extension of the term of two or more patents 
based upon the same regulatory review period, and the patents are 
otherwise eligible for extension pursuant to the requirements of this 
subpart, in the absence of an election by the applicant, the certificate 
of extension of patent term, if appropriate, will be issued upon the 
application for extension of the patent term having the earliest date of 
issuance of those patents for which extension is sought.
    (c) If an application for extension is filed which seeks the 
extension of the term of a patent based upon the same regulatory review 
period as that relied upon in one or more applications for extension 
pursuant to the requirements of this subpart, the certificate of 
extension of patent term will be issued on the application only if the 
patent owner or its agent is the holder of the regulatory approval 
granted with respect to the regulatory review period.
    (d) An application for extension shall be considered complete and 
formal regardless of whether it contains the identification of the 
holder of the regulatory approval granted with respect to the regulatory 
review period. When an application contains such information, or is 
amended to contain such information, it will be considered in 
determining whether an application is eligible for an extension under 
this section. A request may be made of any applicant to supply such 
information within a non-extendable period of not less than one month 
whenever multiple applications for extension of more than one patent are 
received and rely upon the same regulatory review period. Failure to 
provide such information within the period for reply set shall be 
regarded as conclusively establishing that the applicant is not the 
holder of the regulatory approval.
    (e) Determinations made under this section shall be included in the 
notice of final determination of eligibility for extension of the patent 
term pursuant to Sec. 1.750 and shall be regarded as part of that 
determination.

Sec. 1.790  Interim extension of patent term under 35 U.S.C. 156(d)(5).

    (a) An owner of record of a patent or its agent who reasonably 
expects that the applicable regulatory review period described in 
paragraph (1)(B)(ii), (2)(B)(ii), (3)(B)(ii), (4)(B)(ii), or (5)(B)(ii) 
of subsection (g) that began for a product that is the subject of such 
patent may extend beyond the expiration of the patent term in effect may 
submit one or more applications for interim extensions for periods of up 
to one year each. The initial application for interim extension must be 
filed during the period beginning 6 months and ending 15 days before the 
patent term

[[Page 184]]

is due to expire. Each subsequent application for interim extension must 
be filed during the period beginning 60 days before and ending 30 days 
before the expiration of the preceding interim extension. In no event 
will the interim extensions granted under this section be longer than 
the maximum period of extension to which the applicant would be entitled 
under 35 U.S.C. 156(c).
    (b) A complete application for interim extension under this section 
shall include all of the information required for a formal application 
under Sec. 1.740 and a complete application under Sec. 1.741. Sections 
(a)(1), (a)(2), (a)(4), and (a)(6)-(a)(17) of Sec. 1.740 and Sec. 1.741 
shall be read in the context of a product currently undergoing 
regulatory review. Sections (a)(3) and (a)(5) of Sec. 1.740 are not 
applicable to an application for interim extension under this section.
    (c) The content of each subsequent interim extension application may 
be limited to a request for a subsequent interim extension along with a 
statement that the regulatory review period has not been completed along 
with any materials or information required under Secs. 1.740 and 1.741 
that are not present in the preceding interim extension application.

[60 FR 25619, May 12, 1995]



Sec. 1.791  Termination of interim extension granted prior to regulatory
approval of a product for commercial marketing or use.

    Any interim extension granted under 35 U.S.C. 156(d)(5) terminates 
at the end of the 60-day period beginning on the date on which the 
product involved receives permission for commercial marketing or use. If 
within that 60-day period the patent owner or its agent files an 
application for extension under Secs. 1.740 and 1.741 including any 
additional information required under 35 U.S.C. 156(d)(1) not contained 
in the application for interim extension, the patent shall be further 
extended in accordance with the provisions of 35 U.S.C. 156.

              Subpart G_Biotechnology Invention Disclosures

                     Deposit of Biological Material

    Source: 54 FR 34880, Aug. 22, 1989, unless otherwise noted.



Sec. 1.801  Biological material.

    For the purposes of these regulations pertaining to the deposit of 
biological material for purposes of patents for inventions under 35 
U.S.C. 101, the term biological material shall include material that is 
capable of self-replication either directly or indirectly. 
Representative examples include bacteria, fungi including yeast, algae, 
protozoa, eukaryotic cells, cell lines, hybridomas, plasmids, viruses, 
plant tissue cells, lichens and seeds. Viruses, vectors, cell organelles 
and other non-living material existing in and reproducible from a living 
cell may be deposited by deposit of the host cell capable of reproducing 
the non-living material.



Sec. 1.802  Need or opportunity to make a deposit.

    (a) Where an invention is, or relies on, a biological material, the 
disclosure may include reference to a deposit of such biological 
material.
    (b) Biological material need not be deposited unless access to such 
material is necessary for the satisfaction of the statutory requirements 
for patentability under 35 U.S.C. 112. If a deposit is necessary, it 
shall be acceptable if made in accordance with these regulations. 
Biological material need not be deposited, inter alia, if it is known 
and readily avaliable to the public or can be made or isolated without 
undue experimentation. Once deposited in a depository complying with 
these regulations, a biological material will be considered to be 
readily available even though some requirement of law or regulation of 
the United States or of the country in which the depository institution 
is located permits access to the material only under conditions imposed 
for safety, public health or similar reasons.
    (c) The reference to a biological material in a specification 
disclosure or the actual deposit of such material by

[[Page 185]]

an applicant or patent owner does not create any presumption that such 
material is necessary to satisfy 35 U.S.C. 112 or that deposit in 
accordance with these regulations is or was required.



Sec. 1.803  Acceptable depository.

    (a) A deposit shall be recognized for the purposes of these 
regulations if made in
    (1) Any International Depositary Authority (IDA) as established 
under the Budapest Treaty on the International Recognition of the 
Deposit of Microorganisms for the Purposes of Patent Procedure, or
    (2) Any other depository recognized to be suitable by the Office. 
Suitability will be determined by the Director on the basis of the 
administrative and technical competence, and agreement of the depository 
to comply with the terms and conditions applicable to deposits for 
patent purposes. The Director may seek the advice of impartial 
consultants on the suitability of a depository. The depository must:
    (i) Have a continuous existence;
    (ii) Exist independent of the control of the depositor;
    (iii) Possess the staff and facilities sufficient to examine the 
viability of a deposit and store the deposit in a manner which ensures 
that it is kept viable and uncontaminated;
    (iv) Provide for sufficient safety measures to minimize the risk of 
losing biological material deposited with it;
    (v) Be impartial and objective;
    (vi) Furnish samples of the deposited material in an expeditious and 
proper manner; and
    (vii) Promptly notify depositors of its inability to furnish 
samples, and the reasons why.
    (b) A depository seeking status under paragraph (a)(2) of this 
section must direct a communication to the Director which shall:
    (1) Indicate the name and address of the depository to which the 
communication relates;
    (2) Contain detailed information as to the capacity of the 
depository to comply with the requirements of paragraph (a)(2) of this 
section, including information on its legal status, scientific standing, 
staff and facilities;
    (3) Indicate that the depository intends to be available, for the 
purposes of deposit, to any depositor under these same conditions;
    (4) Where the depository intends to accept for deposit only certain 
kinds of biological material, specify such kinds;
    (5) Indicate the amount of any fees that the depository will, upon 
acquiring the status of suitable depository under paragraph (a)(2) of 
this section, charge for storage, viability statements and furnishings 
of samples of the deposit.
    (c) A depository having status under paragraph (a)(2) of this 
section limited to certain kinds of biological material may extend such 
status to additional kinds of biological material by directing a 
communication to the Director in accordance with paragraph (b) of this 
section. If a previous communication under paragraph (b) of this section 
is of record, items in common with the previous communication may be 
incorporated by reference.
    (d) Once a depository is recognized to be suitable by the Director 
or has defaulted or discontinued its performance under this section, 
notice thereof will be published in the Office Gazette of the Patent and 
Trademark Office.



Sec. 1.804  Time of making an original deposit.

    (a) Whenever a biological material is specifically identified in an 
application for patent as filed, an original deposit thereof may be made 
at any time before filing the application for patent or, subject to 
Sec. 1.809, during pendency of the application for patent.
    (b) When the original deposit is made after the effective filing 
date of an application for patent, the applicant must promptly submit a 
statement from a person in a position to corroborate the fact, stating 
that the biological material which is deposited is a biological material 
specifically identified in the application as filed.

[54 FR 34880, Aug. 22, 1989, as amended at 62 FR 53202, Oct. 10, 1997]



Sec. 1.805  Replacement or supplement of deposit.

    (a) A depositor, after receiving notice during the pendency of an 
application

[[Page 186]]

for patent, application for reissue patent or reexamination proceeding, 
that the depository possessing a deposit either cannot furnish samples 
thereof or can furnish samples thereof but the deposit has become 
contaminated or has lost its capability to function as described in the 
specification, shall notify the Office in writing, in each application 
for patent or patent affected. In such a case, or where the Office 
otherwise learns, during the pendency of an application for patent, 
application for reissue patent or reexamination proceeding, that the 
depository possessing a deposit either cannot furnish samples thereof or 
can furnish samples thereof but the deposit has become contaminated or 
has lost its capability to function as described in the specification, 
the need for making a replacement or supplemental deposit will be 
governed by the same considerations governing the need for making an 
original deposit under the provisions set forth in Sec. 1.802(b). A 
replacement or supplemental deposit made during the pendency of an 
application for patent shall not be accepted unless it meets the 
requirements for making an original deposit under these regulations, 
including the requirement set forth under Sec. 1.804(b). A replacement 
or supplemental deposit made in connection with a patent, whether or not 
made during the pendency of an application for reissue patent or a 
reexamination proceeding or both, shall not be accepted unless a 
certificate of correction under Sec. 1.323 is requested by the patent 
owner which meets the terms of paragraphs (b) and (c) of this section.
    (b) A request for certificate of correction under this section shall 
not be granted unless the certificate identifies:
    (1) The accession number for the replacement or supplemental 
deposit;
    (2) The date of the deposit; and
    (3) The name and address of the depository.
    (c) A request for a certificate of correction under this section 
shall not be granted unless the request is made promptly after the 
replacement or supplemental deposit has been made and the request:
    (1) Includes a statement of the reason for making the replacement or 
supplemental deposit;
    (2) Includes a statement from a person in a position to corroborate 
the fact, and stating that the replacement or supplemental deposit is of 
a biological material which is identical to that originally deposited;
    (3) Includes a showing that the patent owner acted diligently--
    (i) In the case of a replacement deposit, in making the deposit 
after receiving notice that samples could no longer be furnished from an 
earlier deposit; or
    (ii) In the case of a supplemental deposit, in making the deposit 
after receiving notice that the earlier deposit had become contaminated 
or had lost its capability to function as described in the 
specification;
    (4) Includes a statement that the term of the replacement or 
supplemental deposit expires no earlier than the term of the deposit 
being replaced or supplemented; and
    (5) Otherwise establishes compliance with these regulations.
    (d) A depositor's failure to replace a deposit, or in the case of a 
patent, to diligently replace a deposit and promptly thereafter request 
a certificate of correction which meets the terms of paragraphs (b) and 
(c) of this section, after being notified that the depository possessing 
the deposit cannot furnish samples thereof, shall cause the application 
or patent involved to be treated in any Office proceeding as if no 
deposit were made.
    (e) In the event a deposit is replaced according to these 
regulations, the Office will apply a rebuttable presumption of identity 
between the original and the replacement deposit where a patent making 
reference to the deposit is relied upon during any Office proceeeding.
    (f) A replacement or supplement deposit made during the pendency of 
an application for patent may be made for any reason.
    (g) In no case is a replacement or supplemental deposit of a 
biological material necessary where the biological material, in 
accordance with Sec. 1.802(b), need not be deposited.

[[Page 187]]

    (h) No replacement deposit of a biological material is necessary 
where a depository can furnish samples thereof but the depository for 
national security, health or environmental safety reasons is unable to 
provide samples to requesters outside of the jurisdiction where the 
depository is located.
    (i) The Office will not recognize in any Office proceeding a 
replacement deposit of a biological material made by a patent owner 
where the depository could furnish samples of the deposit being 
replaced.

[54 FR 34880, Aug. 22, 1989, as amended at 62 FR 53202, Oct. 10, 1997]



Sec. 1.806  Term of deposit.

    A deposit made before or during pendency of an application for 
patent shall be made for a term of at least thirty (30) years and at 
least five (5) years after the most recent request for the furnishing of 
a sample of the deposit was received by the depository. In any case, 
samples must be stored under agreements that would make them available 
beyond the enforceable life of the patent for which the deposit was 
made.



Sec. 1.807  Viability of deposit.

    (a) A deposit of biological material that is capable of self-
replication either directly or indirectly must be viable at the time of 
deposit and during the term of deposit. Viability may be tested by the 
depository. The test must conclude only that the deposited material is 
capable of reproduction. No evidence is necessarily required regarding 
the ability of the deposited material to perform any function described 
in the patent application.
    (b) A viability statement for each deposit of a biological material 
defined in paragraph (a) of this section not made under the Budapest 
Treaty on the International Recognition of the Deposit of Microorganisms 
for the Purposes of Patent Procedure must be filed in the application 
and must contain:
    (1) The name and address of the depository;
    (2) The name and address of the depositor;
    (3) The date of deposit;
    (4) The identity of the deposit and the accession number given by 
the depository;
    (5) The date of the viability test;
    (6) The procedures used to obtain a sample if the test is not done 
by the depository; and
    (7) A statement that the deposit is capable of reproduction.
    (c) If a viability test indicates that the deposit is not viable 
upon receipt, or the examiner cannot, for scientific or other valid 
reasons, accept the statement of viability received from the applicant, 
the examiner shall proceed as if no deposit has been made. The examiner 
will accept the conclusion set forth in a viability statement issued by 
a depository recognized under Sec. 1.803(a).



Sec. 1.808  Furnishing of samples.

    (a) A deposit must be made under conditions that assure that:
    (1) Access to the deposit will be available during pendency of the 
patent application making reference to the deposit to one determined by 
the Director to be entitled thereto under Sec. 1.14 and 35 U.S.C. 122, 
and
    (2) Subject to paragraph (b) of this section, all restrictions 
imposed by the depositor on the availability to the public of the 
deposited material will be irrevocably removed upon the granting of the 
patent.
    (b) The depositor may contract with the depository to require that 
samples of a deposited biological material shall be furnished only if a 
request for a sample, during the term of the patent:
    (1) Is in writing or other tangible form and dated;
    (2) Contains the name and address of the requesting party and the 
accession number of the deposit; and
    (3) Is communicated in writing by the depository to the depositor 
along with the date on which the sample was furnished and the name and 
address of the party to whom the sample was furnished.
    (c) Upon request made to the Office, the Office will certify whether 
a deposit has been stated to have been made under conditions which make 
it available to the public as of the issue date of the patent grant 
provided the request contains:

[[Page 188]]

    (1) The name and address of the depository;
    (2) The accession number given to the deposit;
    (3) The patent number and issue date of the patent referring to the 
deposit; and
    (4) The name and address of the requesting party.



Sec. 1.809  Examination procedures.

    (a) The examiner shall determine pursuant to Sec. 1.104 in each 
application for patent, application for reissue patent or reexamination 
proceeding if a deposit is needed, and if needed, if a deposit actually 
made is acceptable for patent purposes. If a deposit is needed and has 
not been made or replaced or supplemented in accordance with these 
regulations, the examiner, where appropriate, shall reject the affected 
claims under the appropriate provision of 35 U.S.C. 112, explaining why 
a deposit is needed and/or why a deposit actually made cannot be 
accepted.
    (b) The applicant for patent or patent owner shall reply to a 
rejection under paragraph (a) of this section by--
    (1) In the case of an applicant for patent, either making an 
acceptable original, replacement, or supplemental deposit, or assuring 
the Office in writing that an acceptable deposit will be made; or, in 
the case of a patent owner, requesting a certificate of correction of 
the patent which meets the terms of paragraphs (b) and (c) of 
Sec. 1.805, or
    (2) Arguing why a deposit is not needed under the circumstances of 
the application or patent considered and/or why a deposit actually made 
should be accepted. Other replies to the examiner's action shall be 
considered nonresponsive. The rejection will be repeated until either 
paragraph (b)(1) of this section is satisfied or the examiner is 
convinced that a deposit is not needed.
    (c) If an application for patent is otherwise in condition for 
allowance except for a needed deposit and the Office has received a 
written assurance that an acceptable deposit will be made, the Office 
may notify the applicant in a notice of allowability and set a three-
month period of time from the mailing date of the notice of allowability 
within which the deposit must be made in order to avoid abandonment. 
This time period is not extendable under Sec. 1.136 (see Sec. 1.136(c)).
    (d) For each deposit made pursuant to these regulations, the 
specification shall contain:
    (1) The accession number for the deposit;
    (2) The date of the deposit;
    (3) A description of the deposited biological material sufficient to 
specifically identify it and to permit examination; and
    (4) The name and address of the depository.
    (e) Any amendment required by paragraphs (d)(1), (d)(2) or (d)(4) of 
this section must be filed before or with the payment of the issue fee 
(see Sec. 1.312).

Sec. 1.821  Nucleotide and/or amino acid sequence disclosures in patent
applications.

    (a) Nucleotide and/or amino acid sequences as used in Secs. 1.821 
through 1.825 are interpreted to mean an unbranched sequence of four or 
more amino acids or an unbranched sequence of ten or more nucleotides. 
Branched sequences are specifically excluded from this definition. 
Sequences with fewer than four specifically defined nucleotides or amino 
acids are specifically excluded from this section. ``Specifically 
defined'' means those amino acids other than ``Xaa'' and those 
nucleotide bases other than ``n''defined in accordance with the World 
Intellectual Property Organization (WIPO) Handbook on Industrial 
Property Information and Documentation, Standard ST.25: Standard for the 
Presentation of Nucleotide and Amino Acid Sequence Listings in Patent 
Applications (1998), including Tables 1 through 6 in Appendix 2, herein 
incorporated by reference. (Hereinafter ``WIPO Standard ST.25 (1998)''). 
This incorporation by reference was approved by the Director of the 
Federal

Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies of 
WIPO Standard ST.25 (1998) may be obtained from the World Intellectual 
Property Organization; 34 chemin des Colombettes; 1211 Geneva 20 
Switzerland. Copies may also be inspected at the National Archives and 
Records Administration (NARA). For information on the availability of 
this material at NARA, call 202-741-6030, or go to: http://
www.archives.gov/federal_register/code_of_federal_regulations/
ibr_locations.html. Nucleotides and amino acids are further defined as 
follows:
    (1) Nucleotides: Nucleotides are intended to embrace only those 
nucleotides that can be represented using the symbols set forth in WIPO 
Standard ST.25 (1998), Appendix 2, Table 1. Modifications, e.g., 
methylated bases, may be described as set forth in WIPO Standard ST.25 
(1998), Appendix 2, Table 2, but shall not be shown explicitly in the 
nucleotide sequence.
    (2) Amino acids: Amino acids are those L-amino acids commonly found 
in naturally occurring proteins and are listed in WIPO Standard ST.25 
(1998), Appendix 2, Table 3. Those amino acid sequences containing D-
amino acids are not intended to be embraced by this definition. Any 
amino acid sequence that contains post-translationally modified amino 
acids may be described as the amino acid sequence that is initially 
translated using the symbols shown in WIPO Standard ST.25 (1998), 
Appendix 2, Table 3 with the modified positions; e.g., hydroxylations or 
glycosylations, being described as set forth in WIPO Standard ST.25 
(1998), Appendix 2, Table 4, but these modifications shall not be shown 
explicitly in the amino acid sequence. Any peptide or protein that can 
be expressed as a sequence using the symbols in WIPO Standard ST.25 
(1998), Appendix 2, Table 3 in conjunction with a description in the 
Feature section to describe, for example, modified linkages, cross links 
and end caps, non-peptidyl bonds, etc., is embraced by this definition.
    (b) Patent applications which contain disclosures of nucleotide and/
or amino acid sequences, in accordance with the definition in paragraph 
(a) of this section, shall, with regard to the manner in which the 
nucleotide and/or amino acid sequences are presented and described, 
conform exclusively to the requirements of Secs. 1.821 through 1.825.
    (c) Patent applications which contain disclosures of nucleotide and/
or amino acid sequences must contain, as a separate part of the 
disclosure, a paper or compact disc copy (see Sec. 1.52(e)) disclosing 
the nucleotide and/or amino acid sequences and associated information 
using the symbols and format in accordance with the requirements of 
Secs. 1.822 and 1.823. This paper or compact disc copy is referred to 
elsewhere in this subpart as the ``Sequence Listing.'' Each sequence 
disclosed must appear separately in the ``Sequence Listing.'' Each 
sequence set forth in the ``Sequence Listing'' must be assigned a 
separate sequence identifier. The sequence identifiers must begin with 1 
and increase sequentially by integers. If no sequence is present for a 
sequence identifier, the code ``000'' must be used in place of the 
sequence. The response for the numeric identifier <160>must include the 
total number of SEQ ID NOs, whether followed by a sequence or by the 
code ``000.''
    (d) Where the description or claims of a patent application discuss 
a sequence that is set forth in the ``Sequence Listing'' in accordance 
with paragraph (c) of this section, reference must be made to the 
sequence by use of the sequence identifier, preceded by ``SEQ ID NO:'' 
in the text of the description or claims, even if the sequence is also 
embedded in the text of the description or claims of the patent 
application.
    (e) A copy of the ``Sequence Listing'' referred to in paragraph (c) 
of this section must also be submitted in computer readable form (CRF) 
in accordance with the requirements of Sec. 1.824. The computer readable 
form must be a copy of the ``Sequence Listing'' and may not be retained 
as a part of the patent application file. If the computer readable form 
of a new application is to be identical with the computer readable form 
of another application of the applicant on file in the Office, reference 
may be made to the other application and computer readable form in lieu 
of filing a duplicate computer readable form in the new application if

[[Page 190]]

the computer readable form in the other application was compliant with 
all of the requirements of this subpart. The new application must be 
accompanied by a letter making such reference to the other application 
and computer readable form, both of which shall be completely 
identified. In the new application, applicant must also request the use 
of the compliant computer readable ``Sequence Listing'' that is already 
on file for the other application and must state that the paper or 
compact disc copy of the ``Sequence Listing'' in the new application is 
identical to the computer readable copy filed for the other application.
    (f) In addition to the paper or compact disc copy required by 
paragraph (c) of this section and the computer readable form required by 
paragraph (e) of this section, a statement that the ``Sequence Listing'' 
content of the paper or compact disc copy and the computer readable copy 
are the same must be submitted with the computer readable form, e.g., a 
statement that ``the sequence listing information recorded in computer 
readable form is identical to the written (on paper or compact disc) 
sequence listing.''
    (g) If any of the requirements of paragraphs (b) through (f) of this 
section are not satisfied at the time of filing under 35 U.S.C. 111(a) 
or at the time of entering the national stage under 35 U.S.C. 371, 
applicant will be notified and given a period of time within which to 
comply with such requirements in order to prevent abandonment of the 
application. Any submission in reply to a requirement under this 
paragraph must be accompanied by a statement that the submission 
includes no new matter.
    (h) If any of the requirements of paragraphs (b) through (f) of this 
section are not satisfied at the time of filing an international 
application under the Patent Cooperation Treaty (PCT), which application 
is to be searched by the United States International Searching Authority 
or examined by the United States International Preliminary Examining 
Authority, applicant will be sent a notice necessitating compliance with 
the requirements within a prescribed time period. Any submission in 
reply to a requirement under this paragraph must be accompanied by a 
statement that the submission does not include matter which goes beyond 
the disclosure in the international application as filed. If applicant 
fails to timely provide the required computer readable form, the United 
States International Searching Authority shall search only to the extent 
that a meaningful search can be performed without the computer readable 
form and the United States International Preliminary Examining Authority 
shall examine only to the extent that a meaningful examination can be 
performed without the computer readable form.

Sec. 1.822  Symbols and format to be used for nucleotide and/or amino 
acid sequence data.

    (a) The symbols and format to be used for nucleotide and/or amino 
acid sequence data shall conform to the requirements of paragraphs (b) 
through (e) of this section.
    (b) The code for representing the nucleotide and/or amino acid 
sequence characters shall conform to the code set forth in the tables in 
WIPO Standard ST.25 (1998), Appendix 2, Tables 1 and 3. This 
incorporation by reference was approved by the Director of the Federal 
Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies of 
ST.25 may be obtained from the World Intellectual Property Organization; 
34 chemin des Colombettes; 1211 Geneva 20 Switzerland. Copies may also 
be inspected at the National Archives and Records Administration (NARA). 
For information on the availability of this material at NARA, call 202-
741-6030, or go to: http://www.archives.gov/federal_register/
code_of_federal_regulations/ibr_locations.html. No code other than that 
specified in these sections shall be used in nucleotide and amino acid 
sequences. A modified base or modified or unusual amino acid may be 
presented in a given sequence as the corresponding unmodified base or 
amino acid if the modified base or modified or

[[Page 191]]

unusual amino acid is one of those listed in WIPO Standard ST.25 (1998), 
Appendix 2, Tables 2 and 4, and the modification is also set forth in 
the Feature section. Otherwise, each occurrence of a base or amino acid 
not appearing in WIPO Standard ST.25 (1998), Appendix 2, Tables 1 and 3, 
shall be listed in a given sequence as ``n'' or ``Xaa,'' respectively, 
with further information, as appropriate, given in the Feature section, 
preferably by including one or more feature keys listed in WIPO Standard 
ST.25 (1998), Appendix 2, Tables 5 and 6.
    (c) Format representation of nucleotides. (1) A nucleotide sequence 
shall be listed using the lower-case letter for representing the one-
letter code for the nucleotide bases set forth in WIPO Standard ST.25 
(1998), Appendix 2, Table 1.
    (2) The bases in a nucleotide sequence (including introns) shall be 
listed in groups of 10 bases except in the coding parts of the sequence. 
Leftover bases, fewer than 10 in number, at the end of noncoding parts 
of a sequence shall be grouped together and separated from adjacent 
groups of 10 or 3 bases by a space.
    (3) The bases in the coding parts of a nucleotide sequence shall be 
listed as triplets (codons). The amino acids corresponding to the codons 
in the coding parts of a nucleotide sequence shall be typed immediately 
below the corresponding codons. Where a codon spans an intron, the amino 
acid symbol shall be typed below the portion of the codon containing two 
nucleotides.
    (4) A nucleotide sequence shall be listed with a maximum of 16 
codons or 60 bases per line, with a space provided between each codon or 
group of 10 bases.
    (5) A nucleotide sequence shall be presented, only by a single 
strand, in the 5 to 3 direction, from left to right.
    (6) The enumeration of nucleotide bases shall start at the first 
base of the sequence with number 1. The enumeration shall be continuous 
through the whole sequence in the direction 5 to 3. The enumeration 
shall be marked in the right margin, next to the line containing the 
one-letter codes for the bases, and giving the number of the last base 
of that line.
    (7) For those nucleotide sequences that are circular in 
configuration, the enumeration method set forth in paragraph (c)(6) of 
this section remains applicable with the exception that the designation 
of the first base of the nucleotide sequence may be made at the option 
of the applicant.
    (d) Representation of amino acids. (1) The amino acids in a protein 
or peptide sequence shall be listed using the three-letter abbreviation 
with the first letter as an upper case character, as in WIPO Standard 
ST.25 (1998), Appendix 2, Table 3.
    (2) A protein or peptide sequence shall be listed with a maximum of 
16 amino acids per line, with a space provided between each amino acid.
    (3) An amino acid sequence shall be presented in the amino to 
carboxy direction, from left to right, and the amino and carboxy groups 
shall not be presented in the sequence.
    (4) The enumeration of amino acids may start at the first amino acid 
of the first mature protein, with the number 1. When presented, the 
amino acids preceding the mature protein, e.g., pre-sequences, pro-
sequences, pre-pro-sequences and signal sequences, shall have negative 
numbers, counting backwards starting with the amino acid next to number 
1. Otherwise, the enumeration of amino acids shall start at the first 
amino acid at the amino terminal as number 1. It shall be marked below 
the sequence every 5 amino acids. The enumeration method for amino acid 
sequences that is set forth in this section remains applicable for amino 
acid sequences that are circular in configuration, with the exception 
that the designation of the first amino acid of the sequence may be made 
at the option of the applicant.
    (5) An amino acid sequence that contains internal terminator symbols 
(e.g., ``Ter'', ``*'', or ``.'', etc.) may not be represented as a 
single amino acid sequence, but shall be presented as separate amino 
acid sequences.
    (e) A sequence with a gap or gaps shall be presented as a plurality 
of separate sequences, with separate sequence identifiers, with the 
number of separate sequences being equal in number to the number of 
continuous strings of sequence data. A sequence

[[Page 192]]

that is made up of one or more noncontiguous segments of a larger 
sequence or segments from different sequences shall be presented as a 
separate sequence.

Sec. 1.823  Requirements for nucleotide and/or amino acid sequences
as part of the application.

    (a)(1) If the ``Sequence Listing'' required by Sec. 1.821(c) is 
submitted on paper: The ``Sequence Listing,'' setting forth the 
nucleotide and/or amino acid sequence and associated information in 
accordance with paragraph (b) of this section, must begin on a new page 
and must be titled ``Sequence Listing.'' The pages of the ``Sequence 
Listing'' preferably should be numbered independently of the numbering 
of the remainder of the application. Each page of the ``Sequence 
Listing'' shall contain no more than 66 lines and each line shall 
contain no more than 72 characters. The sheet or sheets presenting a 
sequence listing may not include material other than part of the 
sequence listing. A fixed-width font should be used exclusively 
throughout the ``Sequence Listing.''
    (2) If the ``Sequence Listing'' required by Sec. 1.821(c) is 
submitted on compact disc: The ``Sequence Listing'' must be submitted on 
a compact disc in compliance with Sec. 1.52(e). The compact disc may 
also contain table information if the application contains table 
information that may be submitted on a compact disc 
(Sec. 1.52(e)(1)(iii)). The specification must contain an incorporation-
by-reference of the Sequence Listing as required by Sec. 1.52(e)(5). The 
presentation of the ``Sequence Listing'' and other materials on compact 
disc under Sec. 1.821(c) does not substitute for the Computer Readable 
Form that must be submitted on disk, compact disc, or tape in accordance 
with Sec. 1.824.
    (b) The ``Sequence Listing'' shall, except as otherwise indicated, 
include the actual nucleotide and/or amino acid sequence, the numeric 
identifiers and their accompanying information as shown in the following 
table. The numeric identifier shall be used only in the ``Sequence 
Listing.'' The order and presentation of the items of information in the 
``Sequence Listing'' shall conform to the arrangement given below. Each 
item of information shall begin on a new line and shall begin with the 
numeric identifier enclosed in angle brackets as shown. The submission 
of those items of information designated with an ``M'' is mandatory. The 
submission of those items of information designated with an ``O'' is 
optional. Numeric identifiers <110>through <170>shall only be set forth 
at the beginning of the ``Sequence Listing.'' The following table 
illustrates the numeric identifiers.

citations in patent and reexamination files during an ex parte 
reexamination proceeding filed under Sec. 1.510.

[72 FR 18906, Apr. 16, 2007]

         Requirements for Inter Partes Reexamination Proceedings



Sec. 1.903  Service of papers on parties in inter partes reexamination.

    The patent owner and the third party requester will be sent copies 
of Office actions issued during the inter partes reexamination 
proceeding. After filing of a request for inter partes reexamination by 
a third party requester, any document filed by either the patent owner 
or the third party requester must be served on every other party in the 
reexamination proceeding in the manner provided in Sec. 1.248. Any 
document must reflect service or the document may be refused 
consideration by the Office. The failure of the patent owner or the 
third party requester to serve documents may result in their being 
refused consideration.



Sec. 1.904  Notice of inter partes reexamination in Official Gazette.

    A notice of the filing of an inter partes reexamination request will 
be published in the Official Gazette. The notice published in the 
Official Gazette under Sec. 1.11(c) will be considered to be 
constructive notice of the inter partes reexamination proceeding and 
inter partes reexamination will proceed.



Sec. 1.905  Submission of papers by the public in inter partes 
reexamination.

    Unless specifically provided for, no submissions on behalf of any 
third parties other than third party requesters as defined in 35 U.S.C. 
100(e) will be considered unless such submissions are in accordance with 
Sec. 1.915 or entered in the patent file prior to the date of the order 
for reexamination pursuant to Sec. 1.931. Submissions by third parties, 
other than third party requesters, filed after the date of the order for 
reexamination pursuant to Sec. 1.931, must meet the requirements of 
Sec. 1.501 and will be treated in accordance with Sec. 1.902. 
Submissions which do not meet the requirements of Sec. 1.501 will be 
returned.



Sec. 1.906  Scope of reexamination in inter partes reexamination
proceeding.

    (a) Claims in an inter partes reexamination proceeding will be 
examined on the basis of patents or printed publications and, with 
respect to subject matter added or deleted in the reexamination 
proceeding, on the basis of the requirements of 35 U.S.C. 112.
    (b) Claims in an inter partes reexamination proceeding will not be 
permitted to enlarge the scope of the claims of the patent.
    (c) Issues other than those indicated in paragraphs (a) and (b) of 
this section will not be resolved in an inter partes reexamination 
proceeding. If such issues are raised by the patent owner or the third 
party requester during a reexamination proceeding, the existence of such 
issues will be noted by the examiner in the next Office action, in which 
case the patent owner may desire to consider the advisability of filing 
a reissue application to have such issues considered and resolved.

[[Page 200]]



Sec. 1.907  Inter partes reexamination prohibited.

    (a) Once an order to reexamine has been issued under Sec. 1.931, 
neither the third party requester, nor its privies, may file a 
subsequent request for inter partes reexamination of the patent until an 
inter partes reexamination certificate is issued under Sec. 1.997, 
unless authorized by the Director.
    (b) Once a final decision has been entered against a party in a 
civil action arising in whole or in part under 28 U.S.C. 1338 that the 
party has not sustained its burden of proving invalidity of any patent 
claim-in-suit, then neither that party nor its privies may thereafter 
request inter partes reexamination of any such patent claim on the basis 
of issues which that party, or its privies, raised or could have raised 
in such civil action, and an inter partes reexamination requested by 
that party, or its privies, on the basis of such issues may not 
thereafter be maintained by the Office.
    (c) If a final decision in an inter partes reexamination proceeding 
instituted by a third party requester is favorable to patentability of 
any original, proposed amended, or new claims of the patent, then 
neither that party nor its privies may thereafter request inter partes 
reexamination of any such patent claims on the basis of issues which 
that party, or its privies, raised or could have raised in such inter 
partes reexamination proceeding.



Sec. 1.913  Persons eligible to file, and time for filing, a request
for inter partes reexamination.

    (a) Except as provided for in Sec. 1.907 and in paragraph (b) of 
this section, any person other than the patent owner or its privies may, 
at any time during the period of enforceability of a patent which issued 
from an original application filed in the United States on or after 
November 29, 1999, file a request for inter partes reexamination by the 
Office of any claim of the patent on the basis of prior art patents or 
printed publications cited under Sec. 1.501.
    (b) Any request for an inter partes reexamination submitted on or 
after September 16, 2012, will not be accorded a filing date, and any 
such request will not be granted.

[76 FR 59057, Sept. 23, 2011]



Sec. 1.915  Content of request for inter partes reexamination.

    (a) The request must be accompanied by the fee for requesting inter 
partes reexamination set forth in Sec. 1.20(c)(2).
    (b) A request for inter partes reexamination must include the 
following parts:
    (1) An identification of the patent by patent number and every claim 
for which reexamination is requested.
    (2) A citation of the patents and printed publications which are 
presented to provide a showing that there is a reasonable likelihood 
that the requester will prevail with respect to at least one of the 
claims challenged in the request.
    (3) A statement pointing out, based on the cited patents and printed 
publications, each showing of a reasonable likelihood that the requester 
will prevail with respect to at least one of the claims challenged in 
the request, and a detailed explanation of the pertinency and manner of 
applying the patents and printed publications to every claim for which 
reexamination is requested.
    (4) A copy of every patent or printed publication relied upon or 
referred to in paragraphs (b)(1) through (3) of this section, 
accompanied by an English language translation of all the necessary and 
pertinent parts of any non-English language document.
    (5) A copy of the entire patent including the front face, drawings, 
and specification/claims (in double column format) for which 
reexamination is requested, and a copy of any disclaimer, certificate of 
correction, or reexamination certificate issued in the patent. All 
copies must have each page plainly written on only one side of a sheet 
of paper.
    (6) A certification by the third party requester that a copy of the 
request has been served in its entirety on the patent owner at the 
address provided for in Sec. 1.33(c). The name and address of the party 
served must be indicated. If service was not possible, a duplicate copy 
of the request must be supplied to the Office.

[[Page 201]]

    (7) A certification by the third party requester that the estoppel 
provisions of Sec. 1.907 do not prohibit the inter partes reexamination.
    (8) A statement identifying the real party in interest to the extent 
necessary for a subsequent person filing an inter partes reexamination 
request to determine whether that person is a privy.
    (c) If an inter partes request is filed by an attorney or agent 
identifying another party on whose behalf the request is being filed, 
the attorney or agent must have a power of attorney from that party or 
be acting in a representative capacity pursuant to Sec. 1.34.
    (d) If the inter partes request does not include the fee for 
requesting inter partes reexamination required by paragraph (a) of this 
section and meet all the requirements of paragraph (b) of this section, 
then the person identified as requesting inter partes reexamination will 
be so notified and will generally be given an opportunity to complete 
the request within a specified time. Failure to comply with the notice 
will result in the inter partes reexamination request not being granted 
a filing date, and will result in placement of the request in the patent 
file as a citation if it complies with the requirements of Sec. 1.501.

partes reexamination under Sec. 1.915, the examiner will consider the 
request and determine whether or not the request and the prior art 
establish a reasonable likelihood that the requester will prevail with 
respect to at least one of the claims challenged in the request. The 
examiner's determination will be based on the claims in effect at the 
time of the determination, will become a part of the official file of 
the patent, and will be mailed to the patent owner at the address as 
provided for in Sec. 1.33(c) and to the third party requester. If the 
examiner determines that the request has not established a reasonable 
likelihood that the requester will prevail with respect to at least one 
of the challenged claims, the examiner shall refuse the request and 
shall not order inter partes reexamination.

Any such petition must comply with Sec. 1.181(b). If no petition is 
timely filed or if the decision on petition affirms that a reasonable 
likelihood that the requester will prevail with respect to at least one 
of the claims challenged in the request has not been established, the 
determination shall be final and nonappealable.

the merits pursuant to Sec. 1.945, a third party requester may once file 
written comments within a period of 30 days from the date of service of 
the patent owner's response. These comments shall be limited to issues

reexamination, which may be an action closing prosecution. The Office 
action shall set forth all rejections and determinations not to make a 
proposed rejection, and the grounds therefor. An Office action will not 
usually close prosecution if it includes a new ground of rejection which 
was not previously addressed by the

[[Page 204]]

patent owner, unless the new ground was necessitated by an amendment.



Sec. 1.951  Options after Office action closing prosecution in inter
partes reexamination.

    (a) After an Office action closing prosecution in an inter partes 
reexamination, the patent owner may once file comments limited to the

submitting such comments, the examiner shall issue a Right of Appeal 
Notice, unless the examiner reopens prosecution and issues another 
Office action on the merits.
    (b) Expedited Right of Appeal Notice: At any time after the patent 
owner's response to the initial Office action on the merits in an inter 
partes reexamination, the patent owner and all third party requesters 
may stipulate that the issues are appropriate for a final action, which 
would include a final rejection and/or a final determination favorable 
to patentability, and may request the issuance of a Right of Appeal 
Notice. The request must have the concurrence of the patent owner and 
all third party requesters present in the proceeding and must identify 
all of the appealable issues and the positions of the patent owner and 
all third party requesters on those issues. If the examiner determines 
that no other issues are present or should be raised, a Right of Appeal 
Notice limited to the identified issues shall be issued.
    (c) The Right of Appeal Notice shall be a final action, which 
comprises a final rejection setting forth each ground of rejection and/
or final decision favorable to patentability including each 
determination not to make a proposed rejection, an identification of the 
status of each claim, and the reasons for decisions favorable to 
patentability and/or the grounds of rejection for each claim. No 
amendment can be made in response to the Right of Appeal Notice. The 
Right of Appeal Notice shall set a one-month time period for either 
party to appeal. If no notice of appeal is filed, prosecution in the 
inter partes reexamination proceeding will be terminated, and the 
Director will proceed to issue and publish a certificate under 
Sec. 1.997 in accordance with the Right of Appeal Notice.

Sec. 1.956  Patent owner extensions of time in inter partes
reexamination.

reexamination proceeding will be extended only for sufficient cause and 
for a reasonable time specified. Any request for such extension must be 
filed on or before the day on which action by the patent owner is due, 
but in no case will the mere filing of a request effect any extension. 
Any request for such extension must be accompanied by the petition fee 
set forth in Sec. 1.17(g). See Sec. 1.304(a) for extensions of time for

Sec. 1.957  Failure to file a timely, appropriate or complete response
or comment in inter partes reexamination.

    (a) If the third party requester files an untimely or inappropriate 
comment, notice of appeal or brief in an inter partes reexamination, the 
paper will be refused consideration.
    (b) If no claims are found patentable, and the patent owner fails to 
file a timely and appropriate response in an inter partes reexamination 
proceeding, the prosecution in the reexamination proceeding will be a 
terminated prosecution and the Director will proceed to issue and 
publish a certificate concluding the reexamination proceeding under 
Sec. 1.997 in accordance with the last action of the Office.
    (c) If claims are found patentable and the patent owner fails to 
file a timely and appropriate response to any Office action in an inter 
partes reexamination proceeding, further prosecution will be limited to 
the claims found patentable at the time of the failure to respond, and 
to any claims added thereafter which do not expand the scope of the 
claims which were found patentable at that time.
    (d) When action by the patent owner is a bona fide attempt to 
respond and to advance the prosecution and is substantially a complete 
response to the Office action, but consideration of some matter or 
compliance with some requirement has been inadvertently omitted, an 
opportunity to explain and supply the omission may be given.

to carry into effect the decision of the Patent Trial and Appeal Board.
    (b) Upon judgment in the appeal before the Patent Trial and Appeal 
Board, if no further appeal has been taken (Sec. 1.983), the prosecution 
in the inter partes reexamination proceeding will be terminated and the

limited to interference or trial before the Patent Trial and Appeal 
Board, reissue, reexamination, or litigation and the results of such

becomes involved in litigation, the Director shall determine whether or 
not to suspend the inter partes reexamination proceeding.



Sec. 1.989  Merger of concurrent reexamination proceedings.

    (a) If any reexamination is ordered while a prior inter partes 
reexamination proceeding is pending for the same patent and prosecution 
in the prior inter partes reexamination proceeding has not been 
terminated, a decision may be made to merge the two proceedings or to 
suspend one of the two proceedings. Where merger is ordered, the merged 
examination will normally result in the issuance and publication of a 
single reexamination certificate under Sec. 1.997.
    (b) An inter partes reexamination proceeding filed under Sec. 1.913 
which is merged with an ex parte reexamination proceeding filed under 
Sec. 1.510 will result in the merged proceeding being governed by

reexamination proceeding.

    If a reissue application and an inter partes reexamination 
proceeding on which an order pursuant to Sec. 1.931 has been mailed are 
pending concurrently on a patent, a decision may be made to merge the 
two proceedings or to suspend one of the two proceedings. Where merger 
of a reissue application and an inter partes reexamination proceeding is 
ordered, the merged proceeding will be conducted in accordance with 
Secs. 1.171 through 1.179, and the patent owner will be required to 
place and maintain the same claims in the reissue application and the 
inter partes reexamination proceeding during the pendency of the merged 
proceeding. In a merged proceeding the third party requester may 
participate to the extent provided under Secs. 1.902 through 1.997 and 
41.60 through 41.81, except that such participation shall be limited to 
issues within the scope of inter partes reexamination. The examiner's 
actions and any responses by the patent owner or third party requester 
in a merged proceeding will apply to both the reissue application and 
the inter partes reexamination proceeding and be physically entered into 
both files. Any inter partes reexamination proceeding merged with a 
reissue application shall be concluded by the grant of the reissued 
patent.

Sec. 1.993  Suspension of concurrent interference and inter partes
reexamination proceeding.

    If a patent in the process of inter partes reexamination is or 
becomes involved in an interference or trial before the Patent Trial and 
Appeal Board, the Director may suspend the inter partes reexamination, 
interference, or trial. The Director will not consider a request to 
suspend an interference or trial unless a motion under Sec. 41.121(a)(3) 
of this title to suspend the interference or trial has been presented 
to, and denied by, an administrative patent judge and the request is 
filed within ten (10) days of a decision by an administrative patent 
judge denying the motion for suspension or such other time as the 
administrative patent judge may set.

    When a third party requester is involved in one or more proceedings, 
including an inter partes reexamination

[[Page 208]]

proceeding, the merger of such proceedings will be accomplished so as to 
preserve the third party requester's right to participate to the extent 
specifically provided for in these regulations. In merged proceedings 
involving different requesters, any paper filed by one party in the 
merged proceeding shall be served on all other parties of the merged 
proceeding.

of the inter partes reexamination proceeding and the content of the 
patent following the inter partes reexamination proceeding.

as provided for in Sec. 1.33(c). A copy of the certificate will also be 
sent to the third party requester of the inter partes reexamination

    (d) If a certificate has been issued and published which cancels all 
of the claims of the patent, no further Office proceedings will be 
conducted with that patent or any reissue applications or any 
reexamination requests relating thereto.
    (e) If the inter partes reexamination proceeding is terminated by 
the grant of a reissued patent as provided in Sec. 1.991, the reissued 
patent will constitute the reexamination certificate required by this 
section and 35 U.S.C. 316.
    (f) A notice of the issuance of each certificate under this section 
will be published in the Official Gazette.

Sec. 1.1051  Relief from prescribed time limits.

    (a) If the delay in an applicant's failure to act within prescribed 
time limits under the Hague Agreement in connection with requirements 
pertaining to an international design application was unintentional, a 
petition may be filed pursuant to this section to excuse the failure to 
act as to the United States. A grantable petition pursuant to this 
section must be accompanied by:
    (1) A copy of any invitation sent from the International Bureau 
setting a prescribed time limit for which applicant failed to timely 
act;
    (2) The reply required under paragraph (c) of this section, unless 
previously filed;
    (3) The fee as set forth in Sec. 1.17(m);
    (4) A certified copy of the originally filed international design 
application, unless a copy of the international design application was 
previously communicated to the Office from the International Bureau or 
the international design application was filed with the Office as an 
office of indirect filing, and a translation thereof into the English 
language if it was filed in another language;
    (5) A statement that the entire delay in filing the required reply 
from the due date for the reply until the filing of a grantable petition 
pursuant to this paragraph was unintentional. The Director may require 
additional information where there is a question whether the delay was 
unintentional; and
    (6) A terminal disclaimer (and fee as set forth in Sec. 1.20(d)) 
required pursuant to paragraph (d) of this section.

[[Page 214]]

    (b) Any request for reconsideration or review of a decision refusing 
to excuse the applicant's failure to act within prescribed time limits 
in connection with requirements pertaining to an international design 
application upon petition filed pursuant to this section, to be 
considered timely, must be filed within two months of the decision 
refusing to excuse or within such time as set in the decision. Unless a 
decision indicates otherwise, this time period may be extended under the 
provisions of Sec. 1.136.
    (c) Reply. The reply required may be:
    (1) The filing of a continuing application. If the international 
design application has not been subject to international registration, 
the reply must also include a grantable petition under Sec. 1.1023(b) to 
accord the international design application a filing date; or
    (2) A grantable petition under Sec. 1.1052, where the international 
design application was filed with the Office as an office of indirect 
filing.
    (d) Terminal disclaimer. Any petition pursuant to this section must 
be accompanied by a terminal disclaimer and fee as set forth in 
Sec. 1.321 dedicating to the public a terminal part of the term of any 
patent granted thereon equivalent to the period beginning on the due 
date for the reply for which applicant failed to timely act and ending 
on the date of filing of the reply required under paragraph (c) of this 
section and must also apply to any patent granted on a continuing design 
application that contains a specific reference under 35 U.S.C. 120, 121, 
365(c) or 386(c) to the application for which relief under this section 
is sought.



Sec. 1.1052  Conversion to a design application under 35 U.S.C. chapter 16.

    (a) An international design application designating the United 
States filed with the Office as an office of indirect filing and meeting 
the requirements under Sec. 1.53(b) for a filing date for an application 
for a design patent may, on petition under this section, be converted to 
an application for a design patent under Sec. 1.53(b) and accorded a 
filing date as provided therein. A petition under this section must be 
accompanied by the fee set forth in Sec. 1.17(t) and be filed prior to 
publication of the international registration under Article 10(3). The 
conversion of an international design application to an application for 
a design patent under Sec. 1.53(b) will not entitle applicant to a 
refund of the transmittal fee or any fee forwarded to the International 
Bureau, or the application of any such fee toward the filing fee, or any 
other fee, for the application for a design patent under Sec. 1.53(b). 
The application for a design patent resulting from conversion of an 
international design application must also include the basic filing fee 
(Sec. 1.16(b)), the search fee (Sec. 1.16(l)), the examination fee 
(Sec. 1.16(p)), the inventor's oath or declaration (Sec. 1.63 or 1.64), 
and a surcharge if required by Sec. 1.16(f).
    (b) An international design application will be converted to an 
application for a design patent under Sec. 1.53(b) if a decision on 
petition under this section is granted prior to transmittal of the 
international design application to the International Bureau pursuant to 
Sec. 1.1045. Otherwise, a decision granting a petition under this 
section will be effective to convert the international design 
application to an application for a design patent under Sec. 1.53(b) 
only for purposes of the designation of the United States.
    (c) A petition under this section will not be granted in an 
abandoned international design application absent a grantable petition 
under Sec. 1.1051.
    (d) An international design application converted under this section 
is subject to the regulations applicable to a design application filed 
under 35 U.S.C. chapter 16.

design application may only be corrected in accordance with the 
provisions of title 35, United States Code, for correcting patents. Any 
correction under Rule 22 recorded by the International Bureau with 
respect to an abandoned nonprovisional international design application 
will generally not be acted upon by the Office and shall not be given 
effect unless otherwise indicated by the Office.
    (b) A recording of a partial change in ownership in the 
International Register pursuant to Rule 21(7) concerning a transfer of 
less than all designs shall not have effect in the United States.



Sec. 1.1066  Correspondence address for a nonprovisional international
design application.

reference to this section for a nonprovisional international design 
application.



Sec. 1.1067  Title, description, and inventor's oath or declaration.

    (a) The title of the design must designate the particular article. 
Where a nonprovisional international design application does not contain 
a title of the design, the Office may establish a title. No description, 
other than a reference to the drawing, is ordinarily required in a 
nonprovisional international design application.
    (b) An international design application designating the United 
States must include the inventor's oath or declaration. See 
Sec. 1.1021(d). If the applicant is notified in a notice of allowability 
that an oath or declaration in compliance with Sec. 1.63, or substitute 
statement in compliance with Sec. 1.64, executed by or with respect to 
each named inventor has not been filed, the applicant must file each 
required oath or declaration in compliance with Sec. 1.63, or substitute 
statement in compliance with Sec. 1.64, no later than the date on which 
the issue fee is paid to avoid abandonment. This time period is not 
extendable under Sec. 1.136 (see Sec. 1.136(c)).



Sec. 1.1068  Statement of grant of protection.

    Upon issuance of a patent on an international design application 
designating the United States, the Office may send to the International 
Bureau a statement to the effect that protection is granted in the 
United States to those industrial design or designs that are the subject 
of the international registration and covered by the patent.



Sec. 1.1070  Notification of Invalidation.

    (a) Where a design patent that was granted from an international 
design application is invalidated in the United States, and the 
invalidation is no longer subject to any review or appeal, the patentee 
shall inform the Office.
    (b) After receiving a notification of invalidation under paragraph 
(a) of this section or through other means, the Office will notify the 
International Bureau in accordance with Hague Rule 20.



Sec. 1.1071  Grant of protection for an industrial design only upon
issuance of a patent.

    A grant of protection for an industrial design that is the subject 
of an international registration shall only arise in the United States 
through the issuance of a patent pursuant to 35 U.S.C. 389(d) or 171, 
and in accordance with 35 U.S.C. 153.

                    Documents Eligible for Recording



Sec. 3.11  Documents which will be recorded.

    (a) Assignments of applications, patents, and registrations, and 
other documents relating to interests in patent applications and 
patents, accompanied by completed cover sheets as specified in Sec. 3.28 
and Sec. 3.31, will be recorded in the Office. Other documents,

applicant's business, or portion of the business to which the mark 
pertains, if that business is ongoing and existing.

[64 FR 48926, Sept. 8, 1999]

                       Requirements for Recording



Sec. 3.21  Identification of patents and patent applications.

    An assignment relating to a patent must identify the patent by the 
patent number. An assignment relating to a national patent application 
must identify the national patent application by the application number 
(consisting of the series code and the serial number; e.g., 07/123,456). 
An assignment relating to an international patent application which 
designates the United States of America must identify the international 
application by the international application number; e.g., PCT/

[[Page 218]]

US2012/012345. An assignment relating to an international design 
application which designates the United States of America must identify 
the international design application by the international registration 
number or by the U.S. application number assigned to the international 
design application. If an assignment of a patent application filed under 
Sec. 1.53(b) of this chapter is executed concurrently with, or 
subsequent to, the execution of the patent application, but before the 
patent application is filed, it must identify the patent application by 
the name of each inventor and the title of the invention so that there 
can be no mistake as to the patent application intended. If an 
assignment of a provisional application under Sec. 1.53(c) of this 
chapter is executed before the provisional application is filed, it must 
identify the provisional application by the name of each inventor and 
the title of the invention so that there can be no mistake as to the 
provisional application intended.

[80 FR 17969, Apr. 2, 2015]



Sec. 3.24  Requirements for documents and cover sheets relating to
patents and patent applications.

    (a) For electronic submissions: Either a copy of the original 
document or an extract of the original document may be submitted for 
recording. All documents must be submitted as digitized images in Tagged 
Image File Format (TIFF) or another form as prescribed by the Director. 
When printed to a paper size of either 21.6 by 27.9 cm (8\1/2\ by 11 
inches) or 21.0 by 29.7 cm (DIN size A4), the document must be legible 
and a 2.5 cm (one-inch) margin must be present on all sides.
    (b) For paper or facsimile submissions: Either a copy of the 
original document or an extract of the original document must be 
submitted for recording. Only one side of each page may be used. The

by 29.7 cm (DIN size A4), and in either case, a 2.5 cm (one-inch) margin 
must be present on all sides. For paper submissions, the paper used 
should be flexible, strong white, non-shiny, and durable. The Office 
will not return recorded documents, so original documents must not be 
submitted for recording.

[69 FR 29879, May 26, 2004]



Sec. 3.25  Recording requirements for trademark applications and
registrations.

    (a) Documents affecting title. To record documents affecting title 
to a trademark application or registration, a legible cover sheet (see 
Sec. 3.31) and one of the following must be submitted:
    (1) A copy of the original document;
    (2) A copy of an extract from the document evidencing the effect on 
title; or
    (3) A statement signed by both the party conveying the interest and 
the party receiving the interest explaining how the conveyance affects 
title.
    (b) Name changes. Only a legible cover sheet is required (See 
Sec. 3.31).
    (c) All documents. (1) For electronic submissions: All documents 
must be submitted as digitized images in Tagged Image File Format (TIFF) 
or another form as prescribed by the Director. When printed to a paper 
size of either 21.6 by 27.9 cm (8\1/2\ by 11 inches) or 21.0 by 29.7 cm 
(DIN size A4), a 2.5 cm (one-inch) margin must be present on all sides.
    (2) For paper or facsimile submissions: All documents should be 
submitted on white and non-shiny paper that is either 8\1/2\ by 11 
inches (21.6 by 27.9 cm) or DIN size A4 (21.0 by 29.7 cm) with a one-
inch (2.5 cm) margin on all sides in either case. Only one side of each 
page may be used. The Office will not return recorded documents, so 
original documents should not be submitted for recording.

[69 FR 29879, May 26, 2004]



Sec. 3.26  English language requirement.

    The Office will accept and record non-English language documents 
only if accompanied by an English translation signed by the individual 
making the translation.

[62 FR 53202, Oct. 10, 1997]



Sec. 3.27  Mailing address for submitting documents to be recorded.

    Documents and cover sheets submitted by mail for recordation should

[69 FR 29879, May 26, 2004]



Sec. 3.28  Requests for recording.

    Each document submitted to the Office for recording must include a 
single cover sheet (as specified in Sec. 3.31) referring either to those 
patent applications and patents, or to those trademark applications and 
registrations, against which the document is to be recorded. If a 
document to be recorded includes interests in, or transactions 
involving, both patents and trademarks, then separate patent and 
trademark cover sheets, each accompanied by a copy of the document to be 
recorded, must be submitted. If a document to be recorded is not 
accompanied by a completed cover sheet, the document and the incomplete 
cover sheet will be returned pursuant to Sec. 3.51 for proper 
completion, in which case the document and a completed cover sheet 
should be resubmitted.

[70 FR 56128, Sept. 26, 2005]

                        Cover Sheet Requirements



Sec. 3.31  Cover sheet content.

    (a) Each patent or trademark cover sheet required by Sec. 3.28 must 
contain:

    (3) A description of the interest conveyed or transaction to be 
recorded;
    (4) Identification of the interests involved:
    (i) For trademark assignments and trademark name changes: Each 
trademark registration number and each trademark application number, if 
known, against which the Office is to record the document. If the 
trademark application number is not known, a copy of the application or 
a reproduction of the trademark must be submitted, along with an 
estimate of the date that the Office received the application; or
    (ii) For any other document affecting title to a trademark or patent 
application, registration or patent: Each trademark or patent 
application number or each trademark registration number or patent 
against which the document is to be recorded, or an indication that the

    (5) The name and address of the party to whom correspondence 
concerning the request to record the document should be mailed;
    (6) The date the document was executed;
    (7) The signature of the party submitting the document. For an 
assignment document or name change filed electronically, the person who 
signs the cover sheet must either:
    (i) Place a symbol comprised of letters, numbers, and/or punctuation 
marks between forward slash marks (e.g., /Thomas O'Malley III/) in the 
signature block on the electronic submission; or
    (ii) Sign the cover sheet using some other form of electronic 
signature specified by the Director.
    (8) For trademark assignments, the entity and citizenship of the 
party receiving the interest. In addition, if the party receiving the 
interest is a domestic partnership or domestic joint venture, the cover 
sheet must set forth the names, legal entities, and national citizenship 
(or the state or country of organization) of all general partners or 
active members that compose the partnership or joint venture.
    (b) A cover sheet should not refer to both patents and trademarks, 
since any information, including information about pending patent 
applications, submitted with a request for recordation of a document 
against a trademark application or trademark registration will become 
public record upon recordation.
    (c) Each patent cover sheet required by Sec. 3.28 seeking to record 
a governmental interest as provided by Sec. 3.11(b) must:
    (1) Indicate that the document relates to a Government interest; and
    (2) Indicate, if applicable, that the document to be recorded is not 
a document affecting title (see Sec. 3.41(b)).
    (d) Each trademark cover sheet required by Sec. 3.28 seeking to

    (2) Indicate the name of the owner of the application or patent (in 
the space provided for the name and address of the party receiving the 
interest if using an Office-provided form);
    (3) Indicate the name of each other party to the joint research 
agreement party (in the space provided for the name of the party 
conveying the interest if using an Office-provided form); and
    (4) Indicate the date the joint research agreement was executed.
    (h) The assignment cover sheet required by Sec. 3.28 for a patent 
application or patent will be satisfied by the Patent Law Treaty Model 
International Request for Recordation of Change in Applicant or Owner 
Form, Patent Law Treaty Model International Request for Recordation of a 
License/Cancellation of the Recordation of a License Form, Patent Law 
Treaty Model Certificate of Transfer Form or Patent Law Treaty Model 
International Request for Recordation of a Security Interest/
Cancellation of the Recordation of a Security Interest Form, as 
applicable, except where the assignment is also an oath or declaration

Sec. 3.28 must contain a conspicuous indication of an intent to utilize 
the assignment as an oath or declaration under Sec. 1.63 of this 
chapter.

2013]



Sec. 3.34  Correction of cover sheet errors.

    (a) An error in a cover sheet recorded pursuant to Sec. 3.11 will be 
corrected only if:

                                  Fees



Sec. 3.41  Recording fees.

    (a) All requests to record documents must be accompanied by the 
appropriate fee. Except as provided in paragraph (b) of this section, a 
fee is required for each application, patent and registration against 
which the document is recorded as identified in the cover sheet. The 
recording fee is set in Sec. 1.21(h) of this chapter for patents and in 
Sec. 2.6(b)(6) of this chapter for trademarks.
    (b) No fee is required for each patent application and patent 
against which a document required by Executive Order 9424 is to be filed 
if:
    (1) The document does not affect title and is so identified in the 
cover sheet (see Sec. 3.31(c)(2)); and
    (2) The document and cover sheet are either: Faxed or electronically 
submitted as prescribed by the Director, or mailed to the Office in 
compliance with Sec. 3.27.

[63 FR 52159, Sept. 30, 1998, as amended at 69 FR 29879, May 26, 2004]

[[Page 221]]

                      Date and Effect of Recording



Sec. 3.51  Recording date.

    The date of recording of a document is the date the document meeting 
the requirements for recording set forth in this part is filed in the 
Office. A document which does not comply with the identification 
requirements of Sec. 3.21 will not be recorded. Documents not meeting 
the other requirements for recording, for example, a document submitted 
without a completed cover sheet or without the required fee, will be 
returned for correction to the sender where a correspondence address is 
available. The returned papers, stamped with the original date of 
receipt by the Office, will be accompanied by a letter which will 
indicate that if the returned papers are corrected and resubmitted to 
the Office within the time specified in the letter, the Office will 
consider the original date of filing of the papers as the date of 
recording of the document. The procedure set forth in Sec. 1.8 or 
Sec. 1.10 of this chapter may be used for resubmissions of returned 
papers to have the benefit of the date of deposit in the United States 
Postal Service. If the returned papers are not corrected and resubmitted 
within the specified period, the date of filing of the corrected papers 
will be considered to be the date of recording of the document. The 
specified period to resubmit the returned papers will not be extended.

[62 FR 53203, Oct. 10, 1997]



Sec. 3.54  Effect of recording.

    The recording of a document pursuant to Sec. 3.11 is not a 
determination by the Office of the validity of the document or the 
effect that document has on the title to an application, a patent, or a 
registration. When necessary, the Office will determine what effect a 
document has, including whether a party has the authority to take an 
action in a matter pending before the Office.



Sec. 3.56  Conditional assignments.

    Assignments which are made conditional on the performance of certain 
acts or events, such as the payment of money or other condition 
subsequent, if recorded in the Office, are regarded as absolute 
assignments for Office purposes until cancelled with the written consent 
of all parties or by the decree of a court of competent jurisdiction. 
The Office does not determine whether such conditions have been 
fulfilled.



Sec. 3.58  Governmental registers.

    (a) The Office will maintain a Departmental Register to record 
governmental interests required to be recorded by Executive Order 9424. 
This Departmental Register will not be open to public inspection but 
will be available for examination and inspection by duly authorized 
representatives of the Government. Governmental interests recorded on 
the Departmental Register will be available for public inspection as 
provided in Sec. 1.12.
    (b) The Office will maintain a Secret Register to record 
governmental interests required to be recorded by Executive Order 9424. 
Any instrument to be recorded will be placed on this Secret Register at 
the request of the department or agency submitting the same. No 
information will be given concerning any instrument in such record or 
register, and no examination or inspection thereof or of the index 
thereto will be permitted, except on the written authority of the head 
of the department or agency which submitted the instrument and requested 
secrecy, and the approval of such authority by the Director. No 
instrument or record other than the one specified may be examined, and 
the examination must take place in the presence of a designated official 
of the Patent and Trademark Office. When the department or agency which 
submitted an instrument no longer requires secrecy with respect to that 
instrument, it must be recorded anew in the Departmental Register.

[62 FR 53203, Oct. 10, 1997]

                         Domestic Representative



Sec. 3.61  Domestic representative.

    If the assignee of a patent, patent application, trademark 
application or trademark registration is not domiciled in the United 
States, the assignee may designate a domestic representative in a 
document filed in the United States Patent and Trademark Office.

[[Page 222]]

The designation should state the name and address of a person residing 
within the United States on whom may be served process or notice of 
proceedings affecting the application, patent or registration or rights 
thereunder.

[67 FR 79522, Dec. 30, 2002]

                        Action Taken by Assignee



Sec. 3.71  Prosecution by assignee.

    (a) Patents--conducting of prosecution. One or more assignees as 
defined in paragraph (b) of this section may conduct prosecution of a 
national patent application as the applicant under Sec. 1.46 of this 
title, or conduct prosecution of a supplemental examination or 
reexamination proceeding, to the exclusion of the inventor or previous 
applicant or patent owner. Conflicts between purported assignees are 
handled in accordance with Sec. 3.73(c)(3).
    (b) Patents--assignee(s) who can prosecute. The assignee(s) who may 
conduct either the prosecution of a national application for patent as 
the applicant under Sec. 1.46 of this title or a supplemental 
examination or reexamination proceeding are:
    (1) A single assignee. An assignee of the entire right, title and 
interest in the application or patent, or
    (2) Partial assignee(s) together or with inventor(s). All partial 
assignees, or all partial assignees and inventors who have not assigned 
their right, title and interest in the application or patent, who 
together own the entire right, title and interest in the application or 
patent. A partial assignee is any assignee having less than the entire 
right, title and interest in the application or patent. The word 
``assignee'' as used in this chapter means with respect to patent 
matters the single assignee of the entire right, title and interest in 
the application or patent if there is such a single assignee, or all of 
the partial assignees, or all of the partial assignee and inventors who 
have not assigned their interest in the application or patent, who 
together own the entire right, title and interest in the application or 
patent.
    (c) Patents--Becoming of record. An assignee becomes of record as 
the applicant in a national patent application under Sec. 1.46 of this 
title, and in a supplemental examination or reexamination proceeding, by 
filing a statement in compliance with Sec. 3.73(c) that is signed by a 
party who is authorized to act on behalf of the assignee.
    (d) Trademarks. The assignee of a trademark application or 
registration may prosecute a trademark application, submit documents to 
maintain a trademark registration, or file papers against a third party 
in reliance on the assignee's trademark application or registration, to 
the exclusion of the original applicant or previous assignee. The 
assignee must establish ownership in compliance with Sec. 3.73(b).

[65 FR 54682, Sept. 8, 2000, as amended at 77 FR 48825, Aug. 14, 2012]



Sec. 3.73  Establishing right of assignee to take action.

    (a) The original applicant is presumed to be the owner of an 
application for an original patent, and any patent that may issue 
therefrom, unless there is an assignment. The original applicant is 
presumed to be the owner of a trademark application or registration, 
unless there is an assignment.
    (b) In order to request or take action in a trademark matter, the 
assignee must establish its ownership of the trademark property of 
paragraph (a) of this section to the satisfaction of the Director. The 
establishment of ownership by the assignee may be combined with the 
paper that requests or takes the action. Ownership is established by 
submitting to the Office a signed statement identifying the assignee, 
accompanied by either:
    (1) Documentary evidence of a chain of title from the original owner 
to the assignee (e.g., copy of an executed assignment). The documents 
submitted to establish ownership may be required to be recorded pursuant 
to Sec. 3.11 in the assignment records of the Office as a condition to 
permitting the assignee to take action in a matter pending before the 
Office; or
    (2) A statement specifying where documentary evidence of a chain of 
title from the original owner to the assignee is recorded in the 
assignment records of the Office (e.g., reel and frame number).

[[Page 223]]

    (c)(1) In order to request or take action in a patent matter, an 
assignee who is not the original applicant must establish its ownership 
of the patent property of paragraph (a) of this section to the 
satisfaction of the Director. The establishment of ownership by the 
assignee may be combined with the paper that requests or takes the 
action. Ownership is established by submitting to the Office a signed 
statement identifying the assignee, accompanied by either:
    (i) Documentary evidence of a chain of title from the original owner 
to the assignee (e.g., copy of an executed assignment). The submission 
of the documentary evidence must be accompanied by a statement affirming 
that the documentary evidence of the chain of title from the original 
owner to the assignee was or concurrently is being submitted for 
recordation pursuant to Sec. 3.11; or
    (ii) A statement specifying where documentary evidence of a chain of 
title from the original owner to the assignee is recorded in the 
assignment records of the Office (e.g., reel and frame number).
    (2) If the submission is by an assignee of less than the entire 
right, title and interest (e.g., more than one assignee exists) the 
Office may refuse to accept the submission as an establishment of 
ownership unless:
    (i) Each assignee establishes the extent (by percentage) of its 
ownership interest, so as to account for the entire right, title and 
interest in the application or patent by all parties including 
inventors; or
    (ii) Each assignee submits a statement identifying the parties 
including inventors who together own the entire right, title and 
interest and stating that all the identified parties own the entire 
right, title and interest.
    (3) If two or more purported assignees file conflicting statements 
under paragraph (c)(1) of this section, the Director will determine 
which, if any, purported assignee will be permitted to control 
prosecution of the application.
    (d) The submission establishing ownership under paragraph (b) or (c) 
of this section must show that the person signing the submission is a 
person authorized to act on behalf of the assignee by:
    (1) Including a statement that the person signing the submission is 
authorized to act on behalf of the assignee;
    (2) Being signed by a person having apparent authority to sign on 
behalf of the assignee; or
    (3) For patent matters only, being signed by a practitioner of 
record.

                          Issuance to Assignee



Sec. 3.81  Issue of patent to assignee.

    (a) With payment of the issue fee: An application may issue in the 
name of the assignee consistent with the application's assignment where 
a request for such issuance is submitted with payment of the issue fee, 
provided the assignment has been previously recorded in the Office. If 
the assignment has not been previously recorded, the request must state 
that the document has been filed for recordation as set forth in 
Sec. 3.11.
    (b) After payment of the issue fee: Any request for issuance of an 
application in the name of the assignee submitted after the date of 
payment of the issue fee, and any request for a patent to be corrected 
to state the name of the assignee, must state that the assignment was 
submitted for recordation as set forth in Sec. 3.11 before issuance of 
the patent, and must include a request for a certificate of correction 
under Sec. 1.323 of this chapter (accompanied by the fee set forth in 
Sec. 1.20(a)) and the processing fee set forth in Sec. 1.17(i) of this 
chapter.
    (c) Partial assignees. (1) If one or more assignee, together with 
one or more inventor, holds the entire right, title, and interest in the 
application, the patent may issue in the names of the assignee and the 
inventor.
    (2) If multiple assignees hold the entire right, title, and interest 
to the exclusion of all the inventors, the patent may issue in the names 
of the multiple assignees.

[69 FR 29879, May 26, 2004]

[[Page 224]]



Sec. 3.85  Issue of registration to assignee.

    The certificate of registration may be issued to the assignee of the 
applicant, or in a new name of the applicant, provided that the party 
files a written request in the trademark application by the time the 
application is being prepared for issuance of the certificate of 
registration, and the appropriate document is recorded in the Office. If 
the assignment or name change document has not been recorded in the 
Office, then the written request must state that the document has been 
filed for recordation. The address of the assignee must be made of 
record in the application file.

Sec. 4.1  Complaints regarding invention promoters.

    These regulations govern the Patent and Trademark Office's (Office) 
responsibilities under the Inventors' Rights Act of 1999, which can be 
found in the U.S. Code at 35 U.S.C. 297. The Act requires the Office to 
provide a forum for the publication of complaints concerning invention 
promoters. The Office will not conduct any independent investigation of 
the invention promoter. Although the Act provides additional civil 
remedies for persons injured by invention promoters, those remedies must 
be pursued by the injured party without the involvement of the Office.



Sec. 4.2  Definitions.

    (a) Invention Promoter means any person, firm, partnership, 
corporation, or other entity who offers to perform or performs invention 
promotion services for, or on behalf of, a customer, and who holds 
itself out through advertising in any mass media as providing such 
services, but does not include--
    (1) Any department or agency of the Federal Government or of a State 
or local government;
    (2) Any nonprofit, charitable, scientific, or educational 
organization qualified under applicable State law or described under 
section 170(b)(1)(A) of the Internal Revenue Code of 1986;
    (3) Any person or entity involved in the evaluation to determine 
commercial potential of, or offering to license or sell, a utility 
patent or a previously filed nonprovisional utility patent application;
    (4) Any party participating in a transaction involving the sale of 
the stock or assets of a business; or
    (5) Any party who directly engages in the business of retail sales 
of products or the distribution of products.
    (b) Customer means any individual who enters into a contract with an 
invention promoter for invention promotion services.
    (c) Contract for Invention Promotion Services means a contract by 
which an invention promoter undertakes invention promotion services for 
a customer.
    (d) Invention Promotion Services means the procurement or attempted 
procurement for a customer of a firm, corporation, or other entity to 
develop and market products or services that include the invention of 
the customer.



Sec. 4.3  Submitting complaints.

    (a) A person may submit a complaint concerning an invention promoter 
with the Office. A person submitting a complaint should understand that 
the complaint may be forwarded to the invention promoter and may become 
publicly available. The Office will not accept any complaint that 
requests that it be kept confidential.
    (b) A complaint must be clearly marked, or otherwise identified, as 
a complaint under these rules. The complaint must include:
    (1) The name and address of the complainant;
    (2) The name and address of the invention promoter;
    (3) The name of the customer;
    (4) The invention promotion services offered or performed by the 
invention promoter;

[[Page 225]]

    (5) The name of the mass media in which the invention promoter 
advertised providing such services;
    (6) An explanation of the relationship between the customer and the 
invention promoter; and
    (7) A signature of the complainant.
    (c) The complaint should fairly summarize the action of the 
invention promoter about which the person complains. Additionally, the 
complaint should include names and addresses of persons believed to be 
associated with the invention promoter. Complaints, and any replies, 
must be addressed to: Mail Stop 24, Commissioner for Patents, P.O. Box 
1450, Alexandria, Virginia 22313-1450.
    (d) Complaints that do not provide the information requested in 
paragraphs (b) and (c) of this section will be returned. If 
complainant's address is not provided, the complaint will be destroyed.
    (e) No originals of documents should be included with the complaint.
    (f) A complaint can be withdrawn by the complainant or the named 
customer at any time prior to its publication.

[65 FR 3129, Jan. 20, 2000, as amended at 68 FR 14338, Mar. 25, 2003]



Sec. 4.4  Invention promoter reply.

    (a) If a submission appears to meet the requirements of a complaint, 
the invention promoter named in the complaint will be notified of the 
complaint and given 30 days to respond. The invention promoter's 
response will be made available to the public along with the complaint. 
If the invention promoter fails to reply within the 30-day time period 
set by the Office, the complaint will be made available to the public. 
Replies sent after the complaint is made available to the public will 
also be published.
    (b) A response must be clearly marked, or otherwise identified, as a 
response by an invention promoter. The response must contain:
    (1) The name and address of the invention promoter;
    (2) A reference to a complaint forwarded to the invention promoter 
or a complaint previously published;
    (3) The name of the individual signing the response; and
    (4) The title or authority of the individual signing the response.



Sec. 4.5  Notice by publication.

    If the copy of the complaint that is mailed to the invention 
promoter is returned undelivered, then the USPTO will primarily publish 
a Notice of Complaint Received on the USPTO's Internet home page at 
http://www.uspto.gov. Only where the USPTO's Web site is unavailable for 
publication will the USPTO publish the Notice of Complaint in the 
Official Gazette and/or the Federal Register. The invention promoter 
will be given 30 days from such notice to submit a reply to the Notice 
of Complaint. If the USPTO does not receive a reply from the invention 
promoter within 30 days, the complaint alone will become publicly 
available.

[68 FR 9553, Feb. 28, 2003]



Sec. 4.6  Attorneys and Agents.

    Complaints against registered patent attorneys and agents will not 
be treated under this section, unless a complaint fairly demonstrates 
that invention promotion services are involved. Persons having 
complaints about registered patent attorneys or agents should contact 
the Office of Enrollment and Discipline at Mail Stop OED, Director of 
the United States Patent and Trademark Office, PO Box 1450, Alexandria, 
Virginia 22313-1450, and the attorney discipline section of the 
attorney's state licensing bar if an attorney is involved.

                             Secrecy Orders



Sec. 5.1  Applications and correspondence involving national security.

    (a) All correspondence in connection with this part, including 
petitions, should be addressed to: Mail Stop L&R, Commissioner for 
Patents, P.O. Box 1450, Alexandria, Virginia 22313-1450.
    (b) Definitions. (1) Application as used in this part includes 
provisional applications (Sec. 1.9(a)(2) of this chapter), 
nonprovisional applications (Sec. 1.9(a)(3)), international applications 
(Sec. 1.9(b)), or international design applications (Sec. 1.9(n)).
    (2) Foreign application as used in this part includes, for filing in 
a foreign country, foreign patent office, foreign patent agency, or 
international agency (other than the United States Patent and Trademark 
Office acting as a Receiving Office for international applications (35 
U.S.C. 361, Sec. 1.412) or as an office of indirect filing for 
international design applications (35 U.S.C. 382, Sec. 1.1002)) any of 
the following: An application for patent, international application, 
international design application, or application for the registration of 
a utility model, industrial design, or model.
    (c) Patent applications and documents relating thereto that are 
national security classified (see Sec. 1.9(i) of this chapter) and 
contain authorized national security markings (e.g., ``Confidential,'' 
``Secret'' or ``Top Secret'') are accepted by the Office. National 
security classified documents filed in the Office must be either hand-
carried to Licensing and Review or mailed to the Office in compliance 
with paragraph (a) of this section.
    (d) The applicant in a national security classified patent 
application must obtain a secrecy order pursuant to Sec. 5.2(a). If a 
national security classified patent application is filed without a 
notification pursuant to Sec. 5.2(a), the Office will set a time period 
within which either the application must be declassified, or the 
application must be placed under a secrecy order pursuant to 
Sec. 5.2(a), or the applicant must submit evidence of a good faith 
effort to obtain a secrecy order pursuant to Sec. 5.2(a) from the 
relevant department or agency in order to prevent abandonment of the 
application. If evidence of a good faith effort to obtain a secrecy 
order pursuant to Sec. 5.2(a) from the relevant department or agency is 
submitted by the applicant within the time period set by the Office, but 
the application has not been declassified or placed under a secrecy 
order pursuant to Sec. 5.2(a), the Office will again set a time period 
within which either the application must be declassified, or the 
application must be placed under a secrecy order pursuant to 
Sec. 5.2(a), or the applicant must submit evidence of a good faith 
effort to again obtain a secrecy order pursuant to Sec. 5.2(a) from the 
relevant department or agency in order to

[[Page 227]]

prevent abandonment of the application.
    (e) An application will not be published under Sec. 1.211 of this 
chapter or allowed under Sec. 1.311 of this chapter if publication or 
disclosure of the application would be detrimental to national security. 
An application under national security review will not be published at 
least until six months from its filing date or three months from the 
date the application was referred to a defense agency, whichever is 
later. A national security classified patent application will not be 
published under Sec. 1.211 of this chapter or allowed under Sec. 1.311 
of this chapter until the application is declassified and any secrecy 
order under Sec. 5.2(a) has been rescinded.
    (f) Applications on inventions made outside the United States and on 
inventions in which a U.S. Government defense agency has a property 
interest will not be made available to defense agencies.

2, 2015]



Sec. 5.2  Secrecy order.

    (a) When notified by the chief officer of a defense agency that 
publication or disclosure of the invention by the granting of a patent 
would be detrimental to the national security, an order that the 
invention be kept secret will be issued by the Commissioner for Patents.
    (b) Any request for compensation as provided in 35 U.S.C. 183 must 
not be made to the Patent and Trademark Office, but directly to the 
department or agency which caused the secrecy order to be issued.
    (c) An application disclosing any significant part of the subject 
matter of an application under a secrecy order pursuant to paragraph (a) 
of this section also falls within the scope of such secrecy order. Any 
such application that is pending before the Office must be promptly 
brought to the attention of Licensing and Review, unless such 
application is itself under a secrecy order pursuant to paragraph (a) of 
this section. Any subsequently filed application containing any 
significant part of the subject matter of an application under a secrecy 
order pursuant to paragraph (a) of this section must either be hand-
carried to Licensing and Review or mailed to the Office in compliance 
with Sec. 5.1(a).

[24 FR 10381, Dec. 22, 1959, as amended at 62 FR 53203, Oct. 10, 1997; 
65 FR 54683, Sept. 8, 2000]



Sec. 5.3  Prosecution of application under secrecy orders; withholding
patent.

    Unless specifically ordered otherwise, action on the application by 
the Office and prosecution by the applicant will proceed during the time 
an application is under secrecy order to the point indicated in this 
section:
    (a) National applications under secrecy order which come to a final 
rejection must be appealed or otherwise prosecuted to avoid abandonment. 
Appeals in such cases must be completed by the applicant but unless 
otherwise specifically ordered by the Commissioner for Patents will not 
be set for hearing until the secrecy order is removed.
    (b) An interference or derivation will not be instituted involving a 
national application under secrecy order. An applicant whose application 
is under secrecy order may suggest an interference (Sec. 41.202(a) of 
this title), but the Office will not act on the request while the 
application remains under a secrecy order.
    (c) When the national application is found to be in condition for 
allowance except for the secrecy order the applicant and the agency 
which caused the secrecy order to be issued will be notified. This 
notice (which is not a notice of allowance under Sec. 1.311 of this 
chapter) does not require reply by the applicant and places the national 
application in a condition of suspension until the secrecy order is 
removed. When the secrecy order is removed the Patent and Trademark 
Office will issue a notice of allowance under Sec. 1.311 of this 
chapter, or take such other action as may then be warranted.
    (d) International applications and international design applications 
under secrecy order will not be mailed, delivered, or otherwise 
transmitted to the international authorities or the applicant. 
International applications under

[[Page 228]]

secrecy order will be processed up to the point where, if it were not 
for the secrecy order, record and search copies would be transmitted to 
the international authorities or the applicant.

6, 2012; 80 FR 17969, Apr. 2, 2015]



Sec. 5.4  Petition for rescission of secrecy order.

    (a) A petition for rescission or removal of a secrecy order may be 
filed by, or on behalf of, any principal affected thereby. Such petition 
may be in letter form, and it must be in duplicate.
    (b) The petition must recite any and all facts that purport to 
render the order ineffectual or futile if this is the basis of the 
petition. When prior publications or patents are alleged the petition 
must give complete data as to such publications or patents and should be 
accompanied by copies thereof.
    (c) The petition must identify any contract between the Government 
and any of the principals, under which the subject matter of the 
application or any significant part thereof was developed, or to which 
the subject matter is otherwise related. If there is no such contract, 
the petition must so state.
    (d) Appeal to the Secretary of Commerce, as provided by 35 U.S.C. 
181, from a secrecy order cannot be taken until after a petition for 
rescission of the secrecy order has been made and denied. Appeal must be 
taken within sixty days from the date of the denial, and the party 
appealing, as well as the department or agency which caused the order to 
be issued, will be notified of the time and place of hearing.

[24 FR 10381, Dec. 22, 1959, as amended at 62 FR 53204, Oct. 10, 1997]



Sec. 5.5  Permit to disclose or modification of secrecy order.

    (a) Consent to disclosure, or to the filing of an application 
abroad, as provided in 35 U.S.C. 182, shall be made by a ``permit'' or 
``modification'' of the secrecy order.
    (b) Petitions for a permit or modification must fully recite the 
reason or purpose for the proposed disclosure. Where any proposed 
disclosee is known to be cleared by a defense agency to receive 
classified information, adequate explanation of such clearance should be 
made in the petition including the name of the agency or department 
granting the clearance and the date and degree thereof. The petition 
must be filed in duplicate.
    (c) In a petition for modification of a secrecy order to permit 
filing abroad, all countries in which it is proposed to file must be 
made known, as well as all attorneys, agents and others to whom the 
material will be consigned prior to being lodged in the foreign patent 
office. The petition should include a statement vouching for the loyalty 
and integrity of the proposed disclosees and where their clearance 
status in this or the foreign country is known all details should be 
given.
    (d) Consent to the disclosure of subject matter from one application 
under secrecy order may be deemed to be consent to the disclosure of 
common subject matter in other applications under secrecy order so long 
as not taken out of context in a manner disclosing material beyond the 
modification granted in the first application.
    (e) Organizations requiring consent for disclosure of applications 
under secrecy order to persons or organizations in connection with 
repeated routine operation may petition for such consent in the form of 
a general permit. To be successful such petitions must ordinarily recite 
the security clearance status of the disclosees as sufficient for the 
highest classification of material that may be involved.

Secs. 5.6-5.8  [Reserved]

                Licenses for Foreign Exporting and Filing



Sec. 5.11  License for filing in, or exporting to, a foreign country
an application on an invention made in the United States or technical
data relating thereto.

    (a) A license from the Commissioner for Patents under 35 U.S.C. 184 
is required before filing any application for patent including any 
modifications, amendments, or supplements thereto or divisions thereof 
or for the registration of a utility model, industrial design, or model, 
in a foreign country, foreign patent office, foreign patent agency, or 
any international agency (other than the United States Patent and 
Trademark Office acting as a Receiving Office for international 
applications (35 U.S.C. 361, Sec. 1.412) or as an office of indirect 
filing for international design applications (35 U.S.C. 382, 
Sec. 1.1002)), if the invention was made in the United States, and:
    (1) An application on the invention has been filed in the United 
States less than six months prior to the date on which the application 
is to be filed; or
    (2) No application on the invention has been filed in the United 
States.
    (b) The license from the Commissioner for Patents referred to in 
paragraph (a) of this section would also authorize the export of 
technical data abroad for purposes relating to the preparation, filing 
or possible filing and prosecution of a foreign application without 
separately complying with the regulations contained in 22 CFR parts 120 
through 130 (International Traffic in Arms Regulations of the Department 
of State), 15 CFR parts 730 through 774 (Export Administration 
Regulations of the Bureau of Industry and Security, Department of 
Commerce), and 10 CFR part 810 (Assistance to Foreign Atomic Energy 
Activities Regulations of the Department of Energy).
    (c) Where technical data in the form of a patent application, or in 
any form, are being exported for purposes related to the preparation, 
filing or possible filing and prosecution of a foreign application, 
without the license from the Commissioner for Patents referred to in 
paragraphs (a) or (b) of this section, or on an invention not made in 
the United States, the export regulations contained in 22 CFR parts 120 
through 130 (International Traffic in Arms Regulations of the Department 
of State), 15 CFR parts 730 through 774 (Export Administration 
Regulations of the Bureau of Industry and Security, Department of 
Commerce), and 10 CFR part 810 (Assistance to Foreign Atomic Energy 
Activities Regulations of the Department of Energy) must be complied 
with unless a license is not required because a United States 
application was on file at the time of export for at least six months 
without a secrecy order under Sec. 5.2 being placed thereon. The term 
``exported'' means export as it is defined in 22 CFR part 120, 15 CFR 
part 734, and activities covered by 10 CFR part 810.
    (d) If a secrecy order has been issued under Sec. 5.2, an 
application cannot be exported to, or filed in, a foreign country 
(including an international agency in a foreign country), except in 
accordance with Sec. 5.5.
    (e) No license pursuant to paragraph (a) of this section is 
required:
    (1) If the invention was not made in the United States, or
    (2) If the corresponding United States application is not subject to 
a secrecy order under Sec. 5.2, and was filed at least six months prior 
to the date on which the application is filed in a foreign country, or
    (3) For subsequent modifications, amendments and supplements 
containing additional subject matter to, or divisions of, a foreign 
patent application if:
    (i) A license is not, or was not, required under paragraph (e)(2) of 
this section for the foreign application;
    (ii) The corresponding United States application was not required to 
be made available for inspection under 35 U.S.C. 181; and
    (iii) Such modifications, amendments, and supplements do not, or did 
not, change the general nature of the invention in a manner which would 
require any corresponding United States application to be or have been 
available for inspection under 35 U.S.C. 181.
    (f) A license pursuant to paragraph (a) of this section can be 
revoked at

[[Page 230]]

any time upon written notification by the United States Patent and 
Trademark Office. An authorization to file a foreign application 
resulting from the passage of six months from the date of filing of a 
United States patent application may be revoked by the imposition of a 
secrecy order.

Sec. 5.12  Petition for license.

    (a) Filing of an application on an invention made in the United 
States will be considered to include a petition for license under 35 
U.S.C. 184 for the subject matter of the application. The filing receipt 
or other official notice will indicate if a license is granted. If the 
initial automatic petition is not granted, a subsequent petition may be 
filed under paragraph (b) of this section.
    (b) A petition for license must include the fee set forth in 
Sec. 1.17(g) of this chapter, the petitioner's address, and full 
instructions for delivery of the requested license when it is to be 
delivered to other than the petitioner. The petition should be presented 
in letter form.

Sec. 5.13  Petition for license; no corresponding application.

    If no corresponding national, international design, or international 
application has been filed in the United States, the petition for 
license under Sec. 5.12(b) must also be accompanied by a legible copy of 
the material upon which a license is desired. This copy will be retained 
as a measure of the license granted.

[80 FR 17970, Apr. 2, 2015]



Sec. 5.14  Petition for license; corresponding U.S. application.

    (a) When there is a corresponding United States application on file, 
a petition for license under Sec. 5.12(b) must also identify this 
application by application number, filing date, inventor, and title, but 
a copy of the material upon which the license is desired is not 
required. The subject matter licensed will be measured by the disclosure 
of the United States application.
    (b) Two or more United States applications should not be referred to 
in the same petition for license unless they are to be combined in the 
foreign or international application, in which event the petition should 
so state and the identification of each United States application should 
be in separate paragraphs.
    (c) Where the application to be filed or exported abroad contains 
matter not disclosed in the United States application or applications, 
including the case where the combining of two or more United States 
applications introduces subject matter not disclosed in any of them, a 
copy of the application as it is to be filed or exported abroad, must be 
furnished with the petition. If, however, all new matter in the 
application to be filed or exported is readily identifiable, the new 
matter may be submitted in detail and the remainder by reference to the 
pertinent United States application or applications.

Sec. 5.15  Scope of license.

    (a) Applications or other materials reviewed pursuant to Secs. 5.12 
through 5.14, which were not required to be made available for 
inspection by defense agencies under 35 U.S.C. 181, will be eligible for 
a license of the scope provided in this paragraph. This license permits 
subsequent modifications, amendments, and supplements containing 
additional subject matter to, or divisions of, a foreign application, if 
such changes to the application do not alter the general nature of the 
invention in a manner that would require the United States application 
to have been made available for inspection under 35 U.S.C. 181. Grant of 
this license authorizes the export and filing of an application in a 
foreign country or to any foreign patent agency or international patent 
agency when the

[[Page 231]]

subject matter of the foreign application corresponds to that of the 
domestic application. This license includes authority:
    (1) To export and file all duplicate and formal application papers 
in foreign countries or with international agencies;
    (2) To make amendments, modifications, and supplements, including 
divisions, changes or supporting matter consisting of the illustration, 
exemplification, comparison, or explanation of subject matter disclosed 
in the application; and
    (3) To take any action in the prosecution of the foreign application 
provided that the adding of subject matter or taking of any action under 
paragraph (a)(1) or (2) of this section does not change the general 
nature of the invention disclosed in the application in a manner that 
would require such application to have been made available for 
inspection under 35 U.S.C. 181 by including technical data pertaining 
to:
    (i) Defense services or articles designated in the United States 
Munitions List applicable at the time of foreign filing, the unlicensed 
exportation of which is prohibited pursuant to the Arms Export Control 
Act, as amended, and 22 CFR parts 120 through 130; or
    (ii) Restricted Data, sensitive nuclear technology or technology 
useful in the production or utilization of special nuclear material or 
atomic energy, dissemination of which is subject to restrictions of the 
Atomic Energy Act of 1954, as amended, and the Nuclear Non-Proliferation 
Act of 1978, as implemented by the regulations for Assistance to Foreign 
Atomic Energy Activities, 10 CFR part 810, in effect at the time of 
foreign filing.
    (b) Applications or other materials which were required to be made 
available for inspection under 35 U.S.C. 181 will be eligible for a 
license of the scope provided in this paragraph. Grant of this license 
authorizes the export and filing of an application in a foreign country 
or to any foreign patent agency or international patent agency. Further, 
this license includes authority to export and file all duplicate and 
formal papers in foreign countries or with foreign and international 
patent agencies and to make amendments, modifications, and supplements 
to, file divisions of, and take any action in the prosecution of the 
foreign application, provided subject matter additional to that covered 
by the license is not involved.
    (c) A license granted under Sec. 5.12(b) pursuant to Sec. 5.13 or 
Sec. 5.14 shall have the scope indicated in paragraph (a) of this 
section, if it is so specified in the license. A petition, accompanied 
by the required fee (Sec. 1.17(g) of this chapter), may also be filed to 
change a license having the scope indicated in paragraph (b) of this 
section to a license having the scope indicated in paragraph (a) of this 
section. No such petition will be granted if the copy of the material 
filed pursuant to Sec. 5.13 or any corresponding United States 
application was required to be made available for inspection under 35 
U.S.C. 181. The change in the scope of a license will be effective as of 
the date of the grant of the petition.
    (d) In those cases in which no license is required to file or export 
the foreign application, no license is required to file papers in 
connection with the prosecution of the foreign application not involving 
the disclosure of additional subject matter.
    (e) Any paper filed abroad or transmitted to an international patent 
agency following the filing of a foreign application that changes the 
general nature of the subject matter disclosed at the time of filing in 
a manner that would require such application to have been made available 
for inspection under 35 U.S.C. 181 or that involves the disclosure of 
subject matter listed in paragraph (a)(3)(i) or (ii) of this section 
must be separately licensed in the same manner as a foreign application. 
Further, if no license has been granted under Sec. 5.12(a) on filing the 
corresponding United States application, any paper filed abroad or with 
an international patent agency that involves the disclosure of 
additional subject matter must be licensed in the same manner as a 
foreign application.
    (f) Licenses separately granted in connection with two or more 
United States applications may be exercised by combining or dividing the 
disclosures, as desired, provided:

[[Page 232]]

    (1) Subject matter which changes the general nature of the subject 
matter disclosed at the time of filing or which involves subject matter 
listed in paragraph (a)(3) (i) or (ii) of this section is not 
introduced, and
    (2) In the case where at least one of the licenses was obtained 
under Sec. 5.12(b), additional subject matter is not introduced.
    (g) A license does not apply to acts done before the license was 
granted. See Sec. 5.25 for petitions for retroactive licenses.

Secs. 5.16-5.17  [Reserved]



Sec. 5.18  Arms, ammunition, and implements of war.

    (a) The exportation of technical data relating to arms, ammunition, 
and implements of war generally is subject to the International Traffic 
in Arms Regulations of the Department of State (22 CFR parts 120 through 
130); the articles designated as arms, ammunitions, and implements of 
war are enumerated in the U.S. Munitions List (22 CFR part 121). 
However, if a patent applicant complies with regulations issued by the 
Commissioner for Patents under 35 U.S.C. 184, no separate approval from 
the Department of State is required unless the applicant seeks to export 
technical data exceeding that used to support a patent application in a 
foreign country. This exemption from Department of State regulations is 
applicable regardless of whether a license from the Commissioner for 
Patents is required by the provisions of Secs. 5.11 and 5.12 (22 CFR 
part 125).
    (b) When a patent application containing subject matter on the 
Munitions List (22 CFR part 121) is subject to a secrecy order under 
Sec. 5.2 and a petition is made under Sec. 5.5 for a modification of the 
secrecy order to permit filing abroad, a separate request to the 
Department of State for authority to export classified information is 
not required (22 CFR part 125).

[62 FR 53205, Oct. 10, 1997]



Sec. 5.19  Export of technical data.

    (a) Under regulations (15 CFR 734.3(b)(1)(v)) established by the 
Department of Commerce, a license is not required in any case to file a 
patent application or part thereof in a foreign country if the foreign 
filing is in accordance with the regulations (Secs. 5.11 through 5.25) 
of the U.S. Patent and Trademark Office.
    (b) An export license is not required for data contained in a patent 
application prepared wholly from foreign-origin technical data where 
such application is being sent to the foreign inventor to be executed 
and returned to the United States for subsequent filing in the U.S. 
Patent and Trademark Office (15 CFR 734.10(a)).

[70 FR 56129, Sept. 26, 2005]



Sec. 5.20  Export of technical data relating to sensitive nuclear technology.

    Under regulations (10 CFR 810.7) established by the United States 
Department of Energy, an application filed in accordance with the 
regulations (Secs. 5.11 through 5.25) of the Patent and Trademark Office 
and eligible for foreign filing under 35 U.S.C. 184, is considered to be 
information available to the public in published form and a generally 
authorized activity for the purposes of the Department of Energy 
regulations.

[62 FR 53205, Oct. 10, 1997]



Sec. 5.25  Petition for retroactive license.

    (a) A petition for a retroactive license under 35 U.S.C. 184 shall 
be presented in accordance with Sec. 5.13 or Sec. 5.14(a), and shall 
include:
    (1) A listing of each of the foreign countries in which the 
unlicensed patent application material was filed,
    (2) The dates on which the material was filed in each country,
    (3) A verified statement (oath or declaration) containing:
    (i) An averment that the subject matter in question was not under a 
secrecy order at the time it was filed aboard, and that it is not 
currently under a secrecy order,
    (ii) A showing that the license has been diligently sought after 
discovery of the proscribed foreign filing, and
    (iii) An explanation of why the material was filed abroad through 
error

[[Page 233]]

without the required license under Sec. 5.11 first having been obtained, 
and
    (4) The required fee (Sec. 1.17(g) of this chapter).
    (b) The explanation in paragraph (a) of this section must include a 
showing of facts rather than a mere allegation of action through error. 
The showing of facts as to the nature of the error should include 
statements by those persons having personal knowledge of the acts 
regarding filing in a foreign country and should be accompanied by 
copies of any necessary supporting documents such as letters of 
transmittal or instructions for filing. The acts which are alleged to 
constitute error should cover the period leading up to and including 
each of the proscribed foreign filings.
    (c) If a petition for a retroactive license is denied, a time period 
of not less than thirty days shall be set, during which the petition may 
be renewed. Failure to renew the petition within the set time period 
will result in a final denial of the petition. A final denial of a 
petition stands unless a petition is filed under Sec. 1.181 within two 
months of the date of the denial. If the petition for a retroactive 
license is denied with respect to the invention of a pending application 
and no petition under Sec. 1.181 has been filed, a final rejection of 
the application under 35 U.S.C. 185 will be made.
