37 CFR 1.907 - Inter partes reexamination prohibited.

§ 1.907 Inter partes reexamination prohibited.

(a) Once an order to reexamine has been issued under § 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 § 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.
