Summary

A post-grant review can be ended if the person who asked for it and the patent owner both ask to stop, unless the Patent Office already decided the case on the merits. If the review is ended for that petitioner, the rule in section 325(e) will not apply to that petitioner, or to the real party in interest or privy (someone who really controls or benefits from the petition), because of that petition. If no petitioners are left, the Patent Office may end the review or go ahead to a final written decision under section 328(a). Any deal between the patent owner and a petitioner to end the review must be written. A true copy must be filed with the Patent Office before the review ends for those parties. At a party’s request, the deal will be treated as business confidential information, kept apart from the patent’s main file, and shown only to Federal Government agencies on written request or to any person who shows good cause.

(a)In General.—
A post-grant review instituted under this chapter shall be terminated with respect to any petitioner upon the joint request of the petitioner and the patent owner, unless the Office has decided the merits of the proceeding before the request for termination is filed. If the post-grant review is terminated with respect to a petitioner under this section, no estoppel under section 325(e) shall attach to the petitioner, or to the real party in interest or privy of the petitioner, on the basis of that petitioner’s institution of that post-grant review. If no petitioner remains in the post-grant review, the Office may terminate the post-grant review or proceed to a final written decision under section 328(a).
(b)Agreements in Writing.—
Any agreement or understanding between the patent owner and a petitioner, including any collateral agreements referred to in such agreement or understanding, made in connection with, or in contemplation of, the termination of a post-grant review under this section shall be in writing, and a true copy of such agreement or understanding shall be filed in the Office before the termination of the post-grant review as between the parties. At the request of a party to the proceeding, the agreement or understanding shall be treated as business confidential information, shall be kept separate from the file of the involved patents, and shall be made available only to Federal Government agencies on written request, or to any person on a showing of good cause.
