In addition to the definitions in § 41.2, the following definitions apply to proceedings under this subpart unless otherwise clear from the context:

Appellant means any party, whether the owner or a requester, filing a notice of appeal or cross appeal under § 41.61. If more than one party appeals or cross appeals, each appealing or cross appealing party is an appellant with respect to the claims to which his or her appeal or cross appeal is directed.

Filing means filing with a certificate indicating service of the document under § 1.903 of this title.

Owner means the owner of the patent undergoing inter partes reexamination under § 1.915 of this title.

Proceeding means an inter partes reexamination proceeding. Appeal to the Board in an ex parte reexamination proceeding is controlled by subpart B of this part. An inter partes reexamination proceeding is not a contested case subject to subpart D.

Requester means each party, other than the owner, who requested that the patent undergo inter partes reexamination under § 1.915 of this title.

Respondent means any requester responding under § 41.68 to the appellant's brief of the owner, or the owner responding under § 41.68 to the appellant's brief of any requester. No requester may be a respondent to the appellant brief of any other requester.

(a)(1) Upon the issuance of a Right of Appeal Notice under § 1.953 of this title, the owner may appeal to the Board with respect to the final rejection of any claim of the patent by filing a notice of appeal within the time provided in the Right of Appeal Notice and paying the fee set forth in § 41.20(b)(1).

(2) Upon the issuance of a Right of Appeal Notice under § 1.953 of this title, the requester may appeal to the Board with respect to any final decision favorable to the patentability, including any final determination not to make a proposed rejection, of any original, proposed amended, or new claim of the patent by filing a notice of appeal within the time provided in the Right of Appeal Notice and paying the fee set forth in § 41.20(b)(1).

(b)(1) Within fourteen days of service of a requester's notice of appeal under paragraph (a)(2) of this section and upon payment of the fee set forth in § 41.20(b)(1), an owner who has not filed a notice of appeal may file a notice of cross appeal with respect to the final rejection of any claim of the patent.

(2) Within fourteen days of service of an owner's notice of appeal under paragraph (a)(1) of this section and upon payment of the fee set forth in § 41.20(b)(1), a requester who has not filed a notice of appeal may file a notice of cross appeal with respect to any final decision favorable to the patentability, including any final determination not to make a proposed rejection, of any original, proposed amended, or new claim of the patent.

(c) The notice of appeal or cross appeal in the proceeding must identify the appealed claim(s) and must be signed by the owner, the requester, or a duly authorized attorney or agent.

(d) An appeal or cross appeal, when taken, must be taken from all the rejections of the claims in a Right of Appeal Notice which the patent owner proposes to contest or from all the determinations favorable to patentability, including any final determination not to make a proposed rejection, in a Right of Appeal Notice which a requester proposes to contest. Questions relating to matters not affecting the merits of the invention may be required to be settled before an appeal is decided.

(e) The time periods for filing a notice of appeal or cross appeal may not be extended.

(f) If a notice of appeal or cross appeal is timely filed but does not comply with any requirement of this section, appellant will be notified of the reasons for non-compliance and given a non-extendable time period within which to file an amended notice of appeal or cross appeal. If the appellant does not then file an amended notice of appeal or cross appeal within the set time period, or files a notice which does not overcome all the reasons for non-compliance stated in the notification of the reasons for non-compliance, that appellant's appeal or cross appeal will stand dismissed.

(a) Amendments filed after the date of filing an appeal pursuant to § 41.61 canceling claims may be admitted where such cancellation does not affect the scope of any other pending claim in the proceeding.

(b) All other amendments filed after the date of filing an appeal pursuant to § 41.61 will not be admitted except as permitted by § 41.77(b)(1).

(c) Affidavits or other evidence filed after the date of filing an appeal pursuant to § 41.61 will not be admitted except as permitted by reopening prosecution under § 41.77(b)(1).

(a) Jurisdiction over the proceeding passes to the Board upon transmittal of the file, including all briefs and examiner's answers, to the Board.

(b) If, after receipt and review of the proceeding, the Board determines that the file is not complete or is not in compliance with the requirements of this subpart, the Board may relinquish jurisdiction to the examiner or take other appropriate action to permit completion of the file.

(c) Prior to the entry of a decision on the appeal by the Board, the Director may sua sponte order the proceeding remanded to the examiner.

(a) An appellant's brief must be filed no later than two months from the latest filing date of the last-filed notice of appeal or cross appeal or, if any party to the proceeding is entitled to file an appeal or cross appeal but fails to timely do so, no later than two months from the expiration of the time for filing (by the last party entitled to do so) such notice of appeal or cross appeal. The time for filing an appellant's brief or an amended appellant's brief may not be extended.

(b) Once an appellant's brief has been properly filed, any brief must be filed by respondent within one month from the date of service of the appellant's brief. The time for filing a respondent's brief or an amended respondent's brief may not be extended.

(c) The examiner will consider both the appellant's and respondent's briefs and may prepare an examiner's answer under § 41.69.

(d) Any appellant may file a rebuttal brief under § 41.71 within one month of the date of the examiner's answer. The time for filing a rebuttal brief or an amended rebuttal brief may not be extended.

(e) No further submission will be considered and any such submission will be treated in accordance with § 1.939 of this title.

(a)(1) Appellant(s) may once, within time limits for filing set forth in § 41.66, file a brief and serve the brief on all other parties to the proceeding in accordance with § 1.903 of this title.

(2) The brief must be signed by the appellant, or the appellant's duly authorized attorney or agent and must be accompanied by the requisite fee set forth in § 41.20(b)(2).

(b) An appellant's appeal shall stand dismissed upon failure of that appellant to file an appellant's brief, accompanied by the requisite fee, within the time allowed under § 41.66(a).

(c)(1) The appellant's brief shall contain the following items under appropriate headings and in the order indicated in paragraphs (c)(1)(i) through (c)(1)(xi) of this section.

(i) Real party in interest. A statement identifying by name the real party in interest.

(ii) Related appeals and interferences. A statement identifying by application, patent, appeal or interference number all other prior and pending appeals, interferences or judicial proceedings known to appellant, the appellant's legal representative, or assignee which may be related to, directly affect or be directly affected by or have a bearing on the Board's decision in the pending appeal. Copies of any decisions rendered by a court or the Board in any proceeding identified under this paragraph must be included in an appendix as required by paragraph (c)(1)(xi) of this section.

(iii) Status of claims. A statement of the status of all the claims in the proceeding (e.g., rejected, allowed or confirmed, withdrawn, objected to, canceled). If the appellant is the owner, the appellant must also identify the rejected claims whose rejection is being appealed. If the appellant is a requester, the appellant must identify the claims that the examiner has made a determination favorable to patentability, which determination is being appealed.

(iv) Status of amendments. A statement of the status of any amendment filed subsequent to the close of prosecution.

(v) Summary of claimed subject matter. A concise explanation of the subject matter defined in each of the independent claims involved in the appeal, which shall refer to the specification by column and line number, and to the drawing(s), if any, by reference characters. For each independent claim involved in the appeal and for each dependent claim argued separately under the provisions of paragraph (c)(1)(vii) of this section, every means plus function and step plus function as permitted by 35 U.S.C. 112, sixth paragraph, must be identified and the structure, material, or acts described in the specification as corresponding to each claimed function must be set forth with reference to the specification by page and line number, and to the drawing, if any, by reference characters.

(vi) Issues to be reviewed on appeal. A concise statement of each issue presented for review. No new ground of rejection can be proposed by a third party requester appellant, unless such ground was withdrawn by the examiner during the prosecution of the proceeding, and the third party requester has not yet had an opportunity to propose it as a third party requester proposed ground of rejection.

(vii) Argument. The contentions of appellant with respect to each issue presented for review in paragraph (c)(1)(vi) of this section, and the basis therefor, with citations of the statutes, regulations, authorities, and parts of the record relied on. Any arguments or authorities not included in the brief permitted under this section or §§ 41.68 and 41.71 will be refused consideration by the Board, unless good cause is shown. Each issue must be treated under a separate heading. If the appellant is the patent owner, for each ground of rejection in the Right of Appeal Notice which appellant contests and which applies to two or more claims, the claims may be argued separately or as a group. When multiple claims subject to the same ground of rejection are argued as a group by appellant, the Board may select a single claim from the group of claims that are argued together to decide the appeal with respect to the group of claims as to the ground of rejection on the basis of the selected claim alone. Notwithstanding any other provision of this paragraph, the failure of appellant to separately argue claims which appellant has grouped together shall constitute a waiver of any argument that the Board must consider the patentability of any grouped claim separately. Any claim argued separately should be placed under a subheading identifying the claim by number. Claims argued as a group should be placed under a subheading identifying the claims by number. A statement which merely points out what a claim recites will not be considered an argument for separate patentability of the claim.

(viii) Claims appendix. An appendix containing a copy of the claims to be reviewed on appeal.

(ix) Evidence appendix. An appendix containing copies of any evidence submitted pursuant to §§ 1.130, 1.131, or 1.132 of this title or of any other evidence entered by the examiner and relied upon by appellant in the appeal, along with a statement setting forth where in the record that evidence was entered in the record by the examiner. Reference to unentered evidence is not permitted in the brief. See § 41.63 for treatment of evidence submitted after appeal. This appendix may also include copies of the evidence relied upon by the examiner in any ground of rejection to be reviewed on appeal.

(x) Related proceedings appendix. An appendix containing copies of decisions rendered by a court or the Board in any proceeding identified pursuant to paragraph (c)(1)(ii) of this section.

(xi) Certificate of service. A certification that a copy of the brief has been served in its entirety on all other parties to the reexamination proceeding. The names and addresses of the parties served must be indicated.

(2) A brief shall not include any new or non-admitted amendment, or any new or non-admitted affidavit or other evidence. See § 1.116 of this title for amendments, affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.63 for amendments, affidavits or other evidence after the date of filing the appeal.

(d) If a brief is filed which does not comply with all the requirements of paragraph (a) and paragraph (c) of this section, appellant will be notified of the reasons for non-compliance and given a non-extendable time period within which to file an amended brief. If appellant does not file an amended brief within the set time period, or files an amended brief which does not overcome all the reasons for non-compliance stated in the notification, that appellant's appeal will stand dismissed.

(a)(1) Respondent(s) in an appeal may once, within the time limit for filing set forth in § 41.66, file a respondent brief and serve the brief on all parties in accordance with § 1.903 of this title.

(2) The brief must be signed by the party, or the party's duly authorized attorney or agent, and must be accompanied by the requisite fee set forth in § 41.20(b)(2).

(3) The respondent brief shall be limited to issues raised in the appellant brief to which the respondent brief is directed.

(4) A requester's respondent brief may not address any brief of any other requester.

(b)(1) The respondent brief shall contain the following items under appropriate headings and in the order here indicated, and may include an appendix containing only those portions of the record on which reliance has been made.

(i) Real Party in Interest. A statement identifying by name the real party in interest.

(ii) Related Appeals and Interferences. A statement identifying by application, patent, appeal or interference number all other prior and pending appeals, interferences or judicial proceedings known to respondent, the respondent's legal representative, or assignee which may be related to, directly affect or be directly affected by or have a bearing on the Board's decision in the pending appeal. Copies of any decisions rendered by a court or the Board in any proceeding identified under this paragraph must be included in an appendix as required by paragraph (b)(1)(ix) of this section.

(iii) Status of claims. A statement accepting or disputing appellant's statement of the status of claims. If appellant's statement of the status of claims is disputed, the errors in appellant's statement must be specified with particularity.

(iv) Status of amendments. A statement accepting or disputing appellant's statement of the status of amendments. If appellant's statement of the status of amendments is disputed, the errors in appellant's statement must be specified with particularity.

(v) Summary of claimed subject matter. A statement accepting or disputing appellant's summary of the subject matter defined in each of the independent claims involved in the appeal. If appellant's summary of the subject matter is disputed, the errors in appellant's summary must be specified.

(vi) Issues to be reviewed on appeal. A statement accepting or disputing appellant's statement of the issues presented for review. If appellant's statement of the issues presented for review is disputed, the errors in appellant's statement must be specified. A counter statement of the issues for review may be made. No new ground of rejection can be proposed by a requester respondent.

(vii) Argument. A statement accepting or disputing the contentions of appellant with each of the issues presented by the appellant for review. If a contention of the appellant is disputed, the errors in appellant's argument must be specified, stating the basis therefor, with citations of the statutes, regulations, authorities, and parts of the record relied on. Each issue must be treated under a separate heading. An argument may be made with each of the issues stated in the counter statement of the issues, with each counter-stated issue being treated under a separate heading.

(viii) Evidence appendix. An appendix containing copies of any evidence submitted pursuant to §§ 1.130, 1.131, or 1.132 of this title or of any other evidence entered by the examiner and relied upon by respondent in the appeal, along with a statement setting forth where in the record that evidence was entered in the record by the examiner. Reference to unentered evidence is not permitted in the respondent's brief. See § 41.63 for treatment of evidence submitted after appeal.

(ix) Related proceedings appendix. An appendix containing copies of decisions rendered by a court or the Board in any proceeding identified pursuant to paragraph (b)(1)(ii) of this section.

(x) Certificate of service. A certification that a copy of the respondent brief has been served in its entirety on all other parties to the reexamination proceeding. The names and addresses of the parties served must be indicated.

(2) A respondent brief shall not include any new or non-admitted amendment, or any new or non-admitted affidavit or other evidence. See § 1.116 of this title for amendments, affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.63 for amendments, affidavits or other evidence filed after the date of filing the appeal.

(c) If a respondent brief is filed which does not comply with all the requirements of paragraph (a) and paragraph (b) of this section, respondent will be notified of the reasons for non-compliance and given a non-extendable time period within which to file an amended brief. If respondent does not file an amended respondent brief within the set time period, or files an amended respondent brief which does not overcome all the reasons for non-compliance stated in the notification, the respondent brief and any amended respondent brief by that respondent will not be considered.

(a) The primary examiner may, within such time as directed by the Director, furnish a written answer to the owner's and/or requester's appellant brief or respondent brief including, as may be necessary, such explanation of the invention claimed and of the references relied upon, the grounds of rejection, and the reasons for patentability, including grounds for not adopting any proposed rejection. A copy of the answer shall be supplied to the owner and all requesters. If the primary examiner determines that the appeal does not comply with the provisions of §§ 41.61, 41.66, 41.67 and 41.68 or does not relate to an appealable action, the primary examiner shall make such determination of record.

(b) An examiner's answer may not include a new ground of rejection.

(c) An examiner's answer may not include a new determination not to make a proposed rejection of a claim.

(d) Any new ground of rejection, or any new determination not to make a proposed rejection, must be made in an Office action reopening prosecution.

(a) Within one month of the examiner's answer, any appellant may once file a rebuttal brief.

(b)(1) The rebuttal brief of the owner may be directed to the examiner's answer and/or any respondent brief.

(2) The rebuttal brief of the owner shall not include any new or non-admitted amendment, or an affidavit or other evidence. See § 1.116 of this title for amendments, affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.63 for amendments, affidavits or other evidence filed after the date of filing the appeal.

(c)(1) The rebuttal brief of any requester may be directed to the examiner's answer and/or the respondent brief of the owner.

(2) The rebuttal brief of a requester may not be directed to the respondent brief of any other requester.

(3) No new ground of rejection can be proposed by a requester.

(4) The rebuttal brief of a requester shall not include any new or non-admitted affidavit or other evidence. See § 1.116(d) of this title for affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.63(c) for affidavits or other evidence filed after the date of filing the appeal.

(d) The rebuttal brief must include a certification that a copy of the rebuttal brief has been served in its entirety on all other parties to the proceeding. The names and addresses of the parties served must be indicated.

(e) If a rebuttal brief is timely filed under paragraph (a) of this section but does not comply with all the requirements of paragraphs (a) through (d) of this section, appellant will be notified of the reasons for non-compliance and provided with a non-extendable period of one month within which to file an amended rebuttal brief. If the appellant does not file an amended rebuttal brief during the one-month period, or files an amended rebuttal brief which does not overcome all the reasons for non-compliance stated in the notification, that appellant's rebuttal brief and any amended rebuttal brief by that appellant will not be considered.

(a) An oral hearing should be requested only in those circumstances in which an appellant or a respondent considers such a hearing necessary or desirable for a proper presentation of the appeal. An appeal decided on the briefs without an oral hearing will receive the same consideration by the Board as an appeal decided after an oral hearing.

(b) If an appellant or a respondent desires an oral hearing, he or she must file, as a separate paper captioned “REQUEST FOR ORAL HEARING,” a written request for such hearing accompanied by the fee set forth in § 41.20(b)(3) within two months after the date of the examiner's answer. The time for requesting an oral hearing may not be extended. The request must include a certification that a copy of the request has been served in its entirety on all other parties to the proceeding. The names and addresses of the parties served must be indicated.

(c) If no request and fee for oral hearing have been timely filed by appellant or respondent as required by paragraph (b) of this section, the appeal will be assigned for consideration and decision on the briefs without an oral hearing.

(d) If appellant or respondent has complied with all the requirements of paragraph (b) of this section, a hearing date will be set, and notice given to the owner and all requesters. If an oral hearing is held, an oral argument may be presented by, or on behalf of, the primary examiner if considered desirable by either the primary examiner or the Board. The notice shall set a non-extendable period within which all requests for oral hearing shall be submitted by any other party to the appeal desiring to participate in the oral hearing. A hearing will be held as stated in the notice, and oral argument will be limited to thirty minutes for each appellant or respondent who has requested an oral hearing, and twenty minutes for the primary examiner unless otherwise ordered. No appellant or respondent will be permitted to participate in an oral hearing unless he or she has requested an oral hearing and submitted the fee set forth in § 41.20(b)(3).

(e)(1) At the oral hearing, each appellant and respondent may only rely on evidence that has been previously entered and considered by the primary examiner and present argument that has been relied upon in the briefs except as permitted by paragraph (e)(2) of this section. The primary examiner may only rely on argument and evidence relied upon in an answer except as permitted by paragraph (e)(2) of this section. The Board will determine the order of the arguments presented at the oral hearing.

(2) Upon a showing of good cause, appellant, respondent and/or the primary examiner may rely on a new argument based upon a recent relevant decision of either the Board or a Federal Court.

(f) Notwithstanding the submission of a request for oral hearing complying with this rule, if the Board decides that a hearing is not necessary, the Board will so notify the owner and all requesters.

(a) The Board of Patent Appeals and Interferences, in its decision, may affirm or reverse each decision of the examiner on all issues raised on each appealed claim, or remand the reexamination proceeding to the examiner for further consideration. The reversal of the examiner's determination not to make a rejection proposed by the third party requester constitutes a decision adverse to the patentability of the claims which are subject to that proposed rejection which will be set forth in the decision of the Board of Patent Appeals and Interferences as a new ground of rejection under paragraph (b) of this section. The affirmance of the rejection of a claim on any of the grounds specified constitutes a general affirmance of the decision of the examiner on that claim, except as to any ground specifically reversed.

(b) Should the Board reverse the examiner's determination not to make a rejection proposed by a requester, the Board shall set forth in the opinion in support of its decision a new ground of rejection; or should the Board have knowledge of any grounds not raised in the appeal for rejecting any pending claim, it may include in its opinion a statement to that effect with its reasons for so holding, which statement shall constitute a new ground of rejection of the claim. Any decision which includes a new ground of rejection pursuant to this paragraph shall not be considered final for judicial review. When the Board makes a new ground of rejection, the owner, within one month from the date of the decision, must exercise one of the following two options with respect to the new ground of rejection to avoid termination of the appeal proceeding as to the rejected claim:

(1) Reopen prosecution. The owner may file a response requesting reopening of prosecution before the examiner. Such a response must be either an amendment of the claims so rejected or new evidence relating to the claims so rejected, or both.

(2) Request rehearing. The owner may request that the proceeding be reheard under § 41.79 by the Board upon the same record. The request for rehearing must address any new ground of rejection and state with particularity the points believed to have been misapprehended or overlooked in entering the new ground of rejection and also state all other grounds upon which rehearing is sought.

(c) Where the owner has filed a response requesting reopening of prosecution under paragraph (b)(1) of this section, any requester, within one month of the date of service of the owner's response, may once file comments on the response. Such written comments must be limited to the issues raised by the Board's opinion reflecting its decision and the owner's response. Any requester that had not previously filed an appeal or cross appeal and is seeking under this subsection to file comments or a reply to the comments is subject to the appeal and brief fees under § 41.20(b)(1) and (2), respectively, which must accompany the comments or reply.

(d) Following any response by the owner under paragraph (b)(1) of this section and any written comments from a requester under paragraph (c) of this section, the proceeding will be remanded to the examiner. The statement of the Board shall be binding upon the examiner unless an amendment or new evidence not previously of record is made which, in the opinion of the examiner, overcomes the new ground of rejection stated in the decision. The examiner will consider any owner response under paragraph (b)(1) of this section and any written comments by a requester under paragraph (c) of this section and issue a determination that the rejection is maintained or has been overcome.

(e) Within one month of the examiner's determination pursuant to paragraph (d) of this section, the owner or any requester may once submit comments in response to the examiner's determination. Within one month of the date of service of comments in response to the examiner's determination, the owner and any requesters may file a reply to the comments. No requester reply may address the comments of any other requester reply. Any requester that had not previously filed an appeal or cross appeal and is seeking under this subsection to file comments or a reply to the comments is subject to the appeal and brief fees under § 41.20(b)(1) and (2), respectively, which must accompany the comments or reply.

(f) After submission of any comments and any reply pursuant to paragraph (e) of this section, or after time has expired, the proceeding will be returned to the Board which shall reconsider the matter and issue a new decision. The new decision is deemed to incorporate the earlier decision, except for those portions specifically withdrawn.

(g) The time period set forth in paragraph (b) of this section is subject to the extension of time provisions of § 1.956 of this title when the owner is responding under paragraph (b)(1) of this section. The time period set forth in paragraph (b) of this section may not be extended when the owner is responding under paragraph (b)(2) of this section. The time periods set forth in paragraphs (c) and (e) of this section may not be extended.

(a) Parties to the appeal may file a request for rehearing of the decision within one month of the date of:

(1) The original decision of the Board under § 41.77(a),

(2) The original § 41.77(b) decision under the provisions of § 41.77(b)(2),

(3) The expiration of the time for the owner to take action under § 41.77(b)(2), or

(4) The new decision of the Board under § 41.77(f).

(b)(1) The request for rehearing must state with particularity the points believed to have been misapprehended or overlooked in rendering the Board's opinion reflecting its decision. Arguments not raised in the briefs before the Board and evidence not previously relied upon in the briefs are not permitted in the request for rehearing except as permitted by paragraphs (b)(2) and (b)(3) of this section.

(2) Upon a showing of good cause, appellant and/or respondent may present a new argument based upon a recent relevant decision of either the Board or a Federal Court.

(3) New arguments responding to a new ground of rejection made pursuant to § 41.77(b) are permitted.

(c) Within one month of the date of service of any request for rehearing under paragraph (a) of this section, or any further request for rehearing under paragraph (d) of this section, the owner and all requesters may once file comments in opposition to the request for rehearing or the further request for rehearing. The comments in opposition must be limited to the issues raised in the request for rehearing or the further request for rehearing.

(d) If a party to an appeal files a request for rehearing under paragraph (a) of this section, or a further request for rehearing under this section, the Board shall render a decision on the request for rehearing. The decision on the request for rehearing is deemed to incorporate the earlier opinion reflecting its decision for appeal, except for those portions specifically withdrawn on rehearing and is final for the purpose of judicial review, except when noted otherwise in the decision on rehearing. If the Board opinion reflecting its decision on rehearing becomes, in effect, a new decision, and the Board so indicates, then any party to the appeal may, within one month of the new decision, file a further request for rehearing of the new decision under this subsection. Such further request for rehearing must comply with paragraph (b) of this section.

(e) The times for requesting rehearing under paragraph (a) of this section, for requesting further rehearing under paragraph (c) of this section, and for submitting comments under paragraph (b) of this section may not be extended.

The parties to an appeal to the Board may not appeal to the U.S. Court of Appeals for the Federal Circuit under § 1.983 of this title until all parties' rights to request rehearing have been exhausted, at which time the decision of the Board is final and appealable by any party to the appeal to the Board.

In addition to the definitions in § 41.2, the following definitions apply to proceedings under this subpart:

Business day means a day other than a Saturday, Sunday, or Federal holiday within the District of Columbia.

Involved means the Board has declared the patent application, patent, or claim so described to be a subject of the contested case.

(a) Notice of a contested case will be sent to every party to the proceeding. The entry of the notice initiates the proceeding.

(1) Sending notice to another address associated with the party, or

(2) Publishing the notice in the Official Gazette of the United States Patent and Trademark Office.

Before a contested case is initiated, except as the Board may otherwise authorize, for each involved application and patent:

(a) Examination or reexamination must be completed, and

(b) There must be at least one claim that:

(1) Is patentable but for a judgment in the contested case, and

(2) Would be involved in the contested case.

The Board acquires jurisdiction over any involved file when the Board initiates a contested case. Other proceedings for the involved file within the Office are suspended except as the Board may order.

(a) The Board may determine a proper course of conduct in a proceeding for any situation not specifically covered by this part and may enter non-final orders to administer the proceeding.

(b) An administrative patent judge may waive or suspend in a proceeding the application of any rule in this subpart, subject to such conditions as the administrative patent judge may impose.

(c) Times set in this subpart are defaults. In the event of a conflict between a time set by rule and a time set by order, the time set by order is controlling. Action due on a day other than a business day may be completed on the next business day unless the Board expressly states otherwise.

(a) General format requirements. (1) The paper used for filings must be durable and white. A party must choose to file on either A4-sized paper or 81/2 inch × 11 inch paper except in the case of exhibits that require a larger size in order to preserve details of the original. A party may not switch between paper sizes in a single proceeding. Only one side of the paper may be used.

(c) Working copy. Every paper filed must be accompanied by a working copy marked “APJ Copy”.

(d) Specific filing forms—(1) Filing by mail. A paper filed using the EXPRESS MAIL ® service of the United States Postal Service will be deemed to be filed as of “date-in” on the EXPRESS MAIL ® mailing label; otherwise, mail will be deemed to be filed as of the stamped date of receipt at the Board.

(2) Other modes of filing. The Board may authorize other modes of filing, including electronic filing and hand filing, and may set conditions for the use of such other modes.

(e) Service. (1) Papers filed with the Board, if not previously served, must be served simultaneously on every opposing party except as the Board expressly directs.

(2) If a party is represented by counsel, service must be on counsel.

(3) Service must be by EXPRESS MAIL ® or by means at least as fast and reliable as EXPRESS MAIL ®. Electronic service is not permitted without Board authorization.

(4) The date of service does not count in computing the time for responding.

(f) Certificate of service. (1) Papers other than exhibits must include a certificate of service as a separate page at the end of each paper that must be served on an opposing party.

(2) Exhibits must be accompanied by a certificate of service, but a single certificate may accompany any group of exhibits submitted together.

(3) A certificate of service must state:

(i) The date and manner of service,

(ii) The name and address of every person served, and

(iii) For exhibits filed as a group, the name and number of each exhibit served.

(4) A certificate made by a person other than a registered patent practitioner must be in the form of an affidavit.

(a) A party may be represented by counsel. The Board may require a party to appoint a lead counsel. If counsel is not of record in a party's involved application or patent, then a power of attorney for that counsel for the party's involved application or patent must be filed with the notice required in paragraph (b) of this section.

(b) Within 14 days of the initiation of each contested case, each party must file a separate notice identifying its counsel, if any, and providing contact information for each counsel identified or, if the party has no counsel, then for the party. Contact information must, at a minimum, include:

(1) A mailing address;

(2) An address for courier delivery when the mailing address is not available for such delivery (for example, when the mailing address is a Post Office box);

(3) A telephone number;

(4) A facsimile number; and

(5) An electronic mail address.

(c) A party must promptly notify the Board of any change in the contact information required in paragraph (b) of this section.

(a) Request for access or copies. Any request from a party for access to or copies of Office records directly related to a contested case must be filed with the Board. The request must precisely identify the records and in the case of copies include the appropriate fee set under § 1.19(b) of this title.

(b) Authorization of access and copies. Access and copies will ordinarily only be authorized for the following records:

(1) The application file for an involved patent;

(2) An involved application; and

(3) An application for which a party has been accorded benefit under subpart E of this part.

(c) Missing or incomplete copies. If a party does not receive a complete copy of a record within 21 days of the authorization, the party must promptly notify the Board.

(a) Clean copy of claims. Within 14 days of the initiation of the proceeding, each party must file a clean copy of its involved claims and, if a biotechnology material sequence is a limitation, a clean copy of the sequence.

(b) Annotated copy of claims. Within 28 days of the initiation of the proceeding, each party must:

(1) For each involved claim having a limitation that is illustrated in a drawing or biotechnology material sequence, file an annotated copy of the claim indicating in bold face between braces ({}) where each limitation is shown in the drawing or sequence.

(2) For each involved claim that contains a means-plus-function or step-plus-function limitation in the form permitted under 35 U.S.C. 112(6), file an annotated copy of the claim indicating in bold face between braces ({}) the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.

(c) Any motion to add or amend a claim must include:

(1) A clean copy of the claim,

(2) A claim chart showing where the disclosure of the patent or application provides written description of the subject matter of the claim, and

(3) Where applicable, a copy of the claims annotated according to paragraph (b) of this section.

(a) The Board may require a party to provide a notice stating the relief it requests and the basis for its entitlement to relief. The Board may provide for the notice to be maintained in confidence for a limited time.

(b) Effect. If a notice under paragraph (a) of this section is required, a party will be limited to filing substantive motions consistent with the notice. Ambiguities in the notice will be construed against the party. A notice is not evidence except as an admission by a party-opponent.

(c) Correction. A party may move to correct its notice. The motion should be filed promptly after the party becomes aware of the basis for the correction. A correction filed after the time set for filing notices will only be entered if entry would serve the interests of justice.

(a) Types of motions—(1) Substantive motions. Consistent with the notice of requested relief, if any, and to the extent the Board authorizes, a party may file a motion:

(i) To redefine the scope of the contested case,

(ii) To change benefit accorded for the contested subject matter, or

(iii) For judgment in the contested case.

(2) Responsive motions. The Board may authorize a party to file a motion to amend or add a claim, to change inventorship, or otherwise to cure a defect raised in a notice of requested relief or in a substantive motion.

(3) Miscellaneous motions. Any request for relief other than a substantive or responsive motion must be filed as a miscellaneous motion.

(b) Burden of proof. The party filing the motion has the burden of proof to establish that it is entitled to the requested relief.

(c) Content of motions; oppositions and replies. (1) Each motion must be filed as a separate paper and must include:

(i) A statement of the precise relief requested,

(ii) A statement of material facts (see paragraph (d) of this section), and

(iii) A full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence and the governing law, rules, and precedent.

(2) Compliance with rules. Where a rule in part 1 of this title ordinarily governs the relief sought, the motion must make any showings required under that rule in addition to any showings required in this part.

(3) The Board may order additional showings or explanations as a condition for filing a motion.

(d) Statement of material facts. (1) Each material fact shall be set forth as a separate numbered sentence with specific citations to the portions of the record that support the fact.

(2) The Board may require that the statement of material facts be submitted as a separate paper.

(e) Claim charts. Claim charts must be used in support of any paper requiring the comparison of a claim to something else, such as another claim, prior art, or a specification. Claim charts must accompany the paper as an appendix. Claim charts are not a substitute for appropriate argument and explanation in the paper.

(f) The Board may order briefing on any issue that could be raised by motion.

(a) Oppositions and replies must comply with the content requirements for motions and must include a statement identifying material facts in dispute. Any material fact not specifically denied shall be considered admitted.

(b) All arguments for the relief requested in a motion must be made in the motion. A reply may only respond to arguments raised in the corresponding opposition.

(a) A motion, other than a miscellaneous motion, may only be filed according to a schedule the Board sets. The default times for acting are:

(1) An opposition is due 30 days after service of the motion.

(2) A reply is due 30 days after service of the opposition.

(3) A responsive motion is due 30 days after the service of the motion.

(b) Miscellaneous motions. (1) If no time for filing a specific miscellaneous motion is provided in this part or in a Board order:

(i) The opposing party must be consulted prior to filing the miscellaneous motion, and

(ii) If an opposing party plans to oppose the miscellaneous motion, the movant may not file the motion without Board authorization. Such authorization should ordinarily be obtained through a telephone conference including the Board and every other party to the proceeding. Delay in seeking relief may justify a denial of the motion.

(2) An opposition may not be filed without authorization. The default times for acting are:

(i) An opposition to a miscellaneous motion is due five business days after service of the motion.

(ii) A reply to a miscellaneous motion opposition is due three business days after service of the opposition.

(c) Exhibits. Each exhibit must be filed and served with the first paper in which it is cited except as the Board may otherwise order.

(a) Request for oral argument. A party may request an oral argument on an issue raised in a paper within five business days of the filing of the paper. The request must be filed as a separate paper and must specify the issues to be considered.

(b) Copies for panel. If an oral argument is set for a panel, the movant on any issue to be argued must provide three working copies of the motion, the opposition, and the reply. Each party is responsible for providing three working copies of its exhibits relating to the motion.

(c) Length of argument. If a request for oral argument is granted, each party will have a total of 20 minutes to present its arguments, including any time for rebuttal.

(d) Demonstrative exhibits must be served at least five business days before the oral argument and filed no later than the time of the oral argument.

(e) Transcription. The Board encourages the use of a transcription service at oral arguments but, if such a service is to be used, the Board must be notified in advance to ensure adequate facilities are available and a transcript must be filed with the Board promptly after the oral argument.

(a) Order of consideration. The Board may take up motions for decisions in any order, may grant, deny, or dismiss any motion, and may take such other action appropriate to secure the just, speedy, and inexpensive determination of the proceeding. A decision on a motion may include deferral of action on an issue until a later point in the proceeding.

(b) Interlocutory decisions. A decision on motions without a judgment is not final for the purposes of judicial review. A panel decision on an issue will govern further proceedings in the contested case.

(c) Rehearing—(1) Time for request. A request for rehearing of a decision on a motion must be filed within fourteen days of the decision.

(2) No tolling. The filing of a request for rehearing does not toll times for taking action.

(3) Burden on rehearing. The burden of showing a decision should be modified lies with the party attacking the decision. The request must specifically identify:

(i) All matters the party believes to have been misapprehended or overlooked, and

(ii) The place where the matter was previously addressed in a motion, opposition, or reply.

(4) Opposition; reply. Neither an opposition nor a reply to a request for rehearing may be filed without Board authorization.

(5) Panel rehearing. If a decision is not a panel decision, the party requesting rehearing may request that a panel rehear the decision. A panel rehearing a procedural decision will review the decision for an abuse of discretion.

(a) Parties to a contested case may resort to binding arbitration to determine any issue in a contested case. The Office is not a party to the arbitration. The Board is not bound and may independently determine questions of patentability, jurisdiction, and Office practice.

(b) The Board will not authorize arbitration unless:

(1) It is to be conducted according to Title 9 of the United States Code.

(2) The parties notify the Board in writing of their intention to arbitrate.

(3) The agreement to arbitrate:

(i) Is in writing,

(ii) Specifies the issues to be arbitrated,

(iii) Names the arbitrator, or provides a date not more than 30 days after the execution of the agreement for the selection of the arbitrator, and

(iv) Provides that the arbitrator's award shall be binding on the parties and that judgment thereon can be entered by the Board.

(4) A copy of the agreement is filed within 20 days after its execution.

(5) The arbitration is completed within the time the Board sets.

(c) The parties are solely responsible for the selection of the arbitrator and the conduct of proceedings before the arbitrator.

(d) Issues not disposed of by the arbitration will be resolved in accordance with the procedures established in this subpart.

(e) The Board will not consider the arbitration award unless it:

(1) Is binding on the parties,

(2) Is in writing,

(3) States in a clear and definite manner each issue arbitrated and the disposition of each issue, and

(4) Is filed within 20 days of the date of the award.

(f) Once the award is filed, the parties to the award may not take actions inconsistent with the award. If the award is dispositive of the contested subject matter for a party, the Board may enter judgment as to that party.

(a) Effect within Office—(1) Estoppel. A judgment disposes of all issues that were, or by motion could have properly been, raised and decided. A losing party who could have properly moved for relief on an issue, but did not so move, may not take action in the Office after the judgment that is inconsistent with that party's failure to move, except that a losing party shall not be estopped with respect to any contested subject matter for which that party was awarded a favorable judgment.

(2) Final disposal of claim. Adverse judgment against a claim is a final action of the Office requiring no further action by the Office to dispose of the claim permanently.

(b) Request for adverse judgment. A party may at any time in the proceeding request judgment against itself. Actions construed to be a request for adverse judgment include:

(1) Abandonment of an involved application such that the party no longer has an application or patent involved in the proceeding,

(2) Cancellation or disclaiming of a claim such that the party no longer has a claim involved in the proceeding,

(3) Concession of priority or unpatentability of the contested subject matter, and

(4) Abandonment of the contest.

(c) Recommendation. The judgment may include a recommendation for further action by the examiner or by the Director. If the Board recommends rejection of a claim of an involved application, the examiner must enter and maintain the recommended rejection unless an amendment or showing of facts not previously of record is filed which, in the opinion of the examiner, overcomes the recommended rejection.

(d) Rehearing. A party dissatisfied with the judgment may file a request for rehearing within 30 days of the entry of the judgment. The request must specifically identify all matters the party believes to have been misapprehended or overlooked, and the place where the matter was previously addressed in a motion, opposition, or reply.

(a) The Board may impose a sanction against a party for misconduct, including:

(1) Failure to comply with an applicable rule or order in the proceeding;

(2) Advancing a misleading or frivolous request for relief or argument; or

(3) Engaging in dilatory tactics.

(b) Sanctions include entry of:

(1) An order holding certain facts to have been established in the proceeding;

(2) An order expunging, or precluding a party from filing, a paper;

(3) An order precluding a party from presenting or contesting a particular issue;

(4) An order precluding a party from requesting, obtaining, or opposing discovery;

(5) An order excluding evidence;

(6) An order awarding compensatory expenses, including attorney fees;

(7) An order requiring terminal disclaimer of patent term; or

(8) Judgment in the contested case.

(a) Limited discovery. A party is not entitled to discovery except as authorized in this subpart. The parties may agree to discovery among themselves at any time.

(b) Automatic discovery. (1) Within 21 days of a request by an opposing party, a party must:

(i) Serve a legible copy of every requested patent, patent application, literature reference, and test standard mentioned in the specification of the party's involved patent or application, or application upon which the party will rely for benefit, and, if the requested material is in a language other than English, a translation, if available, and

(ii) File with the Board a notice (without copies of the requested materials) of service of the requested materials.

(2) Unless previously served, or the Board orders otherwise, any exhibit cited in a motion or in testimony must be served with the citing motion or testimony.

(c) Additional discovery. (1) A party may request additional discovery. The requesting party must show that such additional discovery is in the interests of justice. The Board may specify conditions for such additional discovery.

(2) When appropriate, a party may obtain production of documents and things during cross examination of an opponent's witness or during testimony authorized under § 41.156.

Evidence that is not taken, sought, or filed in accordance with this subpart shall not be admissible.

(a) Generally. Except as otherwise provided in this subpart, the Federal Rules of Evidence shall apply to contested cases.

(b) Exclusions. Those portions of the Federal Rules of Evidence relating to criminal proceedings, juries, and other matters not relevant to proceedings under this subpart shall not apply.

(c) Modifications in terminology. Unless otherwise clear from context, the following terms of the Federal Rules of Evidence shall be construed as indicated:

Appellate court means United States Court of Appeals for the Federal Circuit or a United States district court when judicial review is under 35 U.S.C. 146.

Civil action, civil proceeding, action, and trial mean contested case.

Courts of the United States, U.S. Magistrate, court, trial court, and trier of fact mean Board.

(d) Exhibit list. Each party must maintain an exhibit list with the exhibit number and a brief description of each exhibit. If the exhibit is not filed, the exhibit list should note that fact. The Board may require the filing of a current exhibit list prior to acting on a motion.

(a) Deposition. Objections to deposition evidence must be made during the deposition. Evidence to cure the objection must be provided during the deposition unless the parties to the deposition stipulate otherwise on the deposition record.

(b) Other than deposition. For evidence other than deposition evidence:

(1) Objection. Any objection must be served within five business days of service of evidence, other than deposition evidence, to which the objection is directed.

(b) Outside the United States. For testimony or production sought outside the United States, the motion must also:

(1) In the case of testimony. (i) Identify the foreign country and explain why the party believes the witness can be compelled to testify in the foreign country, including a description of the procedures that will be used to compel the testimony in the foreign country and an estimate of the time it is expected to take to obtain the testimony; and

(2) In the case of production of a document or thing. (i) Identify the foreign country and explain why the party believes production of the document or thing can be compelled in the foreign country, including a description of the procedures that will be used to compel production of the document or thing in the foreign country and an estimate of the time it is expected to take to obtain production of the document or thing; and

(ii) Demonstrate that the party has made reasonable efforts to obtain the agreement of the individual or entity having possession, custody, or control of the document to produce the document or thing in the United States but has been unsuccessful in obtaining that agreement, even though the party has offered to pay the expenses of producing the document or thing in the United States.

(a) Form. Direct testimony must be submitted in the form of an affidavit except when the testimony is compelled under 35 U.S.C. 24, in which case it may be in the form of a deposition transcript.

(b) Time and location. (1) Uncompelled direct testimony may be taken at any time; otherwise, testimony may only be taken during such time period as the Board may authorize.

(2) Other testimony. (i) Except as the Board otherwise orders, authorized testimony may be taken at any reasonable time and location within the United States before any disinterested official authorized to administer oaths at that location.

(ii) Testimony outside the United States may only be taken as the Board specifically directs.

(c) Notice of deposition. (1) Prior to the taking of testimony, all parties to the proceeding must agree on the time and place for taking testimony. If the parties cannot agree, the party seeking the testimony must initiate a conference with the Board to set a time and place.

(2) Cross-examination should ordinarily take place after any supplemental evidence relating to the direct testimony has been filed and more than a week before the filing date for any paper in which the cross-examination testimony is expected to be used. A party requesting cross-examination testimony of more than one witness may choose the order in which the witnesses are to be cross-examined.

(3) In the case of direct testimony, at least three business days prior to the conference in paragraph (c)(1) of this section, the party seeking the direct testimony must serve:

(i) A list and copy of each document under the party's control and on which the party intends to rely, and

(ii) A list of, and proffer of reasonable access to, any thing other than a document under the party's control and on which the party intends to rely.

(1) Why the test or data is being used,

(2) How the test was performed and the data was generated,

(c) Patent interferences shall be administered such that pendency before the Board is normally no more than two years.

In addition to the definitions in §§ 41.2 and 41.100, the following definitions apply to proceedings under this subpart:

Accord benefit means Board recognition that a patent application provides a proper constructive reduction to practice under 35 U.S.C. 102(g)(1).

Constructive reduction to practice means a described and enabled anticipation under 35 U.S.C. 102(g)(1) in a patent application of the subject matter of a count. Earliest constructive reduction to practice means the first constructive reduction to practice that has been continuously disclosed through a chain of patent applications including in the involved application or patent. For the chain to be continuous, each subsequent application must have been co-pending under 35 U.S.C. 120 or 121 or timely filed under 35 U.S.C. 119 or 365(a).

Count means the Board's description of the interfering subject matter that sets the scope of admissible proofs on priority. Where there is more than one count, each count must describe a patentably distinct invention.

Involved claim means, for the purposes of 35 U.S.C. 135(a), a claim that has been designated as corresponding to the count.

Senior party means the party entitled to the presumption under § 41.207(a)(1) that it is the prior inventor. Any other party is a junior party.

Threshold issue means an issue that, if resolved in favor of the movant, would deprive the opponent of standing in the interference. Threshold issues may include:

(1) No interference-in-fact, and

(2) In the case of an involved application claim first made after the publication of the movant's application or issuance of the movant's patent:

(i) Repose under 35 U.S.C. 135(b) in view of the movant's patent or published application, or

(ii) Unpatentability for lack of written description under 35 U.S.C. 112(1) of an involved application claim where the applicant suggested, or could have suggested, an interference under § 41.202(a).

(a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:

(1) Provide sufficient information to identify the application or patent with which the applicant seeks an interference,

(2) Identify all claims the applicant believes interfere, propose one or more counts, and show how the claims correspond to one or more counts,

(3) For each count, provide a claim chart comparing at least one claim of each party corresponding to the count and show why the claims interfere within the meaning of § 41.203(a),

(4) Explain in detail why the applicant will prevail on priority,

(5) If a claim has been added or amended to provoke an interference, provide a claim chart showing the written description for each claim in the applicant's specification, and

(6) For each constructive reduction to practice for which the applicant wishes to be accorded benefit, provide a chart showing where the disclosure provides a constructive reduction to practice within the scope of the interfering subject matter.

(b) Patentee. A patentee cannot suggest an interference under this section but may, to the extent permitted under § 1.99 and § 1.291 of this title, alert the examiner of an application claiming interfering subject matter to the possibility of an interference.

(c) Examiner. An examiner may require an applicant to add a claim to provoke an interference. Failure to satisfy the requirement within a period (not less than one month) the examiner sets will operate as a concession of priority for the subject matter of the claim. If the interference would be with a patent, the applicant must also comply with paragraphs (a)(2) through (a)(6) of this section. The claim the examiner proposes to have added must, apart from the question of priority under 35 U.S.C. 102(g):

(1) Be patentable to the applicant, and

(2) Be drawn to patentable subject matter claimed by another applicant or patentee.

(d) Requirement to show priority under 35 U.S.C. 102(g). (1) When an applicant has an earliest constructive reduction to practice that is later than the apparent earliest constructive reduction to practice for a patent or published application claiming interfering subject matter, the applicant must show why it would prevail on priority.

(2) If an applicant fails to show priority under paragraph (d)(1) of this section, an administrative patent judge may nevertheless declare an interference to place the applicant under an order to show cause why judgment should not be entered against the applicant on priority. New evidence in support of priority will not be admitted except on a showing of good cause. The Board may authorize the filing of motions to redefine the interfering subject matter or to change the benefit accorded to the parties.

(e) Sufficiency of showing. (1) A showing of priority under this section is not sufficient unless it would, if unrebutted, support a determination of priority in favor of the party making the showing.

(2) When testimony or production necessary to show priority is not available without authorization under § 41.150(c) or § 41.156(a), the showing shall include:

(i) Any necessary interrogatory, request for admission, request for production, or deposition request, and

(ii) A detailed proffer of what the response to the interrogatory or request would be expected to be and an explanation of the relevance of the response to the question of priority.

(a) Interfering subject matter. An interference exists if the subject matter of a claim of one party would, if prior art, have anticipated or rendered obvious the subject matter of a claim of the opposing party and vice versa.

(b) Notice of declaration. An administrative patent judge declares the patent interference on behalf of the Director. A notice declaring an interference identifies:

(1) The interfering subject matter;

(2) The involved applications, patents, and claims;

(3) The accorded benefit for each count; and

(4) The claims corresponding to each count.

(c) Redeclaration. An administrative patent judge may redeclare a patent interference on behalf of the Director to change the declaration made under paragraph (b) of this section.

(d) A party may suggest the addition of a patent or application to the interference or the declaration of an additional interference. The suggestion should make the showings required under § 41.202(a) of this part.

(a) Priority statement. (1) A party may not submit evidence of its priority in addition to its accorded benefit unless it files a statement setting forth all bases on which the party intends to establish its entitlement to judgment on priority.

(2) The priority statement must:

(i) State the date and location of the party's earliest corroborated conception,

(ii) State the date and location of the party's earliest corroborated actual reduction to practice,

(iii) State the earliest corroborated date on which the party's diligence began, and

(iv) Provide a copy of the earliest document upon which the party will rely to show conception.

(3) If a junior party fails to file a priority statement overcoming a senior party's accorded benefit, judgment shall be entered against the junior party absent a showing of good cause.

(b) Other substantive motions. The Board may require a party to list the motions it intends to file, including sufficient detail to place the Board and the opponent on notice of the precise relief sought.

(c) Filing and service. The Board will set the times for filing and serving statements required under this section.

An administrative patent judge may decline to declare, or if already declared the Board may issue judgment in, an interference between an application and another application or patent that are commonly owned.

(a) Priority—(1) Order of invention. Parties are presumed to have invented interfering subject matter in the order of the dates of their accorded benefit for each count. If two parties are accorded the benefit of the same earliest date of constructive reduction to practice, then neither party is entitled to a presumption of priority with respect to the other such party.

(2) Evidentiary standard. Priority may be proved by a preponderance of the evidence except a party must prove priority by clear and convincing evidence if the date of its earliest constructive reduction to practice is after the issue date of an involved patent or the publication date under 35 U.S.C. 122(b) of an involved application or patent.

(b) Claim correspondence. (1) For the purposes of determining priority and derivation, all claims of a party corresponding to the count are presumed to stand or fall together. To challenge this presumption, a party must file a timely substantive motion to have a corresponding claim designated as not corresponding to the count. No presumption based on claim correspondence regarding the grouping of claims exists for other grounds of unpatentability.

(2) A claim corresponds to a count if the subject matter of the count, treated as prior art to the claim, would have anticipated or rendered obvious the subject matter of the claim.

(c) Cross-applicability of prior art. When a motion for judgment of unpatentability against an opponent's claim on the basis of prior art is granted, each of the movant's claims corresponding to the same count as the opponent's claim will be presumed to be unpatentable in view of the same prior art unless the movant in its motion rebuts this presumption.

The general requirements for motions in contested cases are stated at § 41.121(c).

(a) In an interference, substantive motions must:

(1) Raise a threshold issue,

(2) Seek to change the scope of the definition of the interfering subject matter or the correspondence of claims to the count,

(3) Seek to change the benefit accorded for the count, or

(4) Seek judgment on derivation or on priority.

(b) To be sufficient, a motion must provide a showing, supported with appropriate evidence, such that, if unrebutted, it would justify the relief sought. The burden of proof is on the movant.

(c) Showing patentability. (1) A party moving to add or amend a claim must show the claim is patentable.

(2) A party moving to add or amend a count must show the count is patentable over prior art.
