Title 35 › PART III — PATENTS AND PROTECTION OF PATENT RIGHTS › CHAPTER 31 — INTER PARTES REVIEW › § 317
If both a petitioner and the patent owner ask to end an inter partes review, the Patent Office must stop 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) will apply to that petitioner or to its real party in interest or privy. If no petitioners remain, the Office may end the review or go forward to a final written decision under section 318(a). Any deal between the patent owner and a petitioner to end the review must be written and a true copy filed with the Patent Office before the review ends between those parties. At a party’s request, the written agreement can be kept as business confidential, kept separate from the patent file, and shown only to federal agencies with a written request or to anyone who shows good cause.
