Title 35 › Part PART III— - PATENTS AND PROTECTION OF PATENT RIGHTS › Chapter CHAPTER 31— - INTER PARTES REVIEW › § 317
When a petitioner and the patent owner jointly ask to end an inter partes review, the Office must end the review for that petitioner unless the Office already decided the case on the merits. If the review is ended this way, no estoppel under section 315(e) applies to that petitioner, its real party in interest, or a privy. If no petitioners remain, the Office may stop the review or go ahead with a final written decision under section 318(a). Any agreement between the patent owner and petitioner to end the review must be written and filed with the Office before the review ends. If a party asks, the filed agreement will be kept as business confidential information, kept separate from the patent file, and shown only to Federal Government agencies on written request or to others who show good cause.
