§312. Determination of issue by Director

(a) Reexamination.—Not later than 3 months after the filing of a request for inter partes reexamination under section 311, the Director shall determine whether a substantial new question of patentability affecting any claim of the patent concerned is raised by the request, with or without consideration of other patents or printed publications.

(c) Final Decision.—A determination by the Director under subsection (a) shall be final and non-appealable. Upon a determination that no substantial new question of patentability has been raised, the Director may refund a portion of the inter partes reexamination fee required under section 311.

(a) Patent Owner.—The patent owner involved in an inter partes reexamination proceeding under this chapter—

(b) Third-Party Requester.—A third-party requester—

(1) may appeal under the provisions of section 134, and may appeal under the provisions of sections 141 through 144, with respect to any final decision favorable to the patentability of any original or proposed amended or new claim of the patent; and

(Added Pub. L. 106–113, div. B, §1000(a)(9) [title IV, §4604(a)], Nov. 29, 1999, 113 Stat. 1536, 1501A–569; amended Pub. L. 107–273, div. C, title III, §§13106(a), 13202(a)(4), (c)(1), Nov. 2, 2002, 116 Stat. 1900–1902.)

If this section is held to be unenforceable, the enforceability of the remainder of this subtitle [see Short Title of 1999 Amendment note set out under section 1 of this title] or of this title [see Tables for classification] shall not be denied as a result.”

(b) Amended or New Claim.—Any proposed amended or new claim determined to be patentable and incorporated into a patent following an inter partes reexamination proceeding shall have the same effect as that specified in section 252 of this title for reissued patents on the right of any person who made, purchased, or used within the United States, or imported into the United States, anything patented by such proposed amended or new claim, or who made substantial preparation therefor, prior to issuance of a certificate under the provisions of subsection (a) of this section.

(Added Pub. L. 106–113, div. B, §1000(a)(9) [title IV, §4604(a)], Nov. 29, 1999, 113 Stat. 1536, 1501A–569; amended Pub. L. 107–273, div. C, title III, §13202(c)(1), Nov. 2, 2002, 116 Stat. 1902.)

Section Referred to in Other Sections

This section is referred to in section 317 of this title.

§317. Inter partes reexamination prohibited

(a) Order for Reexamination.—Notwithstanding any provision of this chapter, once an order for inter partes reexamination of a patent has been issued under section 313, neither the third-party requester nor its privies,1 may file a subsequent request for inter partes reexamination of the patent until an inter partes reexamination certificate is issued and published under section 316, unless authorized by the Director.

(b) Final Decision.—Once a final decision has been entered against a party in a civil action arising in whole or in part under section 1338 of title 28,1 that the party has not sustained its burden of proving the invalidity of any patent claim in suit or if a final decision in an inter partes reexamination proceeding instituted by a third-party requester is favorable to the patentability of any original or proposed amended or new claim of the patent, then neither that party nor its privies may thereafter request an 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 or inter partes reexamination proceeding, 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, notwithstanding any other provision of this chapter. This subsection does not prevent the assertion of invalidity based on newly discovered prior art unavailable to the third-party requester and the Patent and Trademark Office at the time of the inter partes reexamination proceedings.

(Added Pub. L. 106–113, div. B, §1000(a)(9) [title IV, §4604(a)], Nov. 29, 1999, 113 Stat. 1536, 1501A–570; amended Pub. L. 107–273, div. C, title III, §13202(a)(5), (c)(1), Nov. 2, 2002, 116 Stat. 1901, 1902.)

Subsec. (a). Pub. L. 107–273, §13202(a)(5)(A), substituted “third-party requester nor its privies” for “patent owner nor the third-party requester, if any, nor privies of either”.

Subsec. (b). Pub. L. 107–273, §13202(a)(5)(B), struck out “United States Code,” after “title 28,”.

1 So in original. The comma probably should not appear.

§318. Stay of litigation

Once an order for inter partes reexamination of a patent has been issued under section 313, the patent owner may obtain a stay of any pending litigation which involves an issue of patentability of any claims of the patent which are the subject of the inter partes reexamination order, unless the court before which such litigation is pending determines that a stay would not serve the interests of justice.

(Added Pub. L. 106–113, div. B, §1000(a)(9) [title IV, §4604(a)], Nov. 29, 1999, 113 Stat. 1536, 1501A–570; amended Pub. L. 107–273, div. C, title III, §13202(c)(1), Nov. 2, 2002, 116 Stat. 1902.)
