Summary

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.

(a)An inter partes 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 inter partes review is terminated with respect to a petitioner under this section, no estoppel under section 315(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 inter partes review. If no petitioner remains in the inter partes review, the Office may terminate the review or proceed to a final written decision under section 318(a).
(b)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 an inter partes 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 inter partes 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.
