Title 35 › Part III— PATENTS AND PROTECTION OF PATENT RIGHTS › Chapter 32— POST-GRANT REVIEW › § 327
A post-grant review must end for a petitioner if the petitioner and the patent owner both ask for it, unless the Patent Office already decided the case on the merits. If the review ends that way, the petitioner and their real party in interest or privy will not be subject to estoppel under section 325(e) because they started the review. If no petitioner is left in the review, the Patent Office can either stop the review or go forward and issue a final written decision under section 328(a). Any deal between the patent owner and the petitioner to end the review must be written and filed with the Patent Office before the review ends. If a party asks, the agreement can be treated as confidential business information, kept separate from the patent file, and shown only to federal agencies on written request or to others who show good cause.
