  • (a) The patent owner may file a preliminary response to the petition. The response is limited to setting forth the reasons why no post-grant review should be instituted under 35 U.S.C. 324 and can include supporting evidence. The preliminary response is subject to the word count under § 42.24.
  • (b) Due date. The preliminary response must be filed no later than three months after the date of a notice indicating that the request to institute a post-grant review has been granted a filing date. A patent owner may expedite the proceeding by filing an election to waive the patent owner preliminary response.
  • (c) [Reserved]
  • (d) No amendment. The preliminary response shall not include any amendment.
  • (e) Disclaim Patent Claims. The patent owner may file a statutory disclaimer under 35 U.S.C. 253(a) in compliance with § 1.321(a), disclaiming one or more claims in the patent. No post-grant review will be instituted based on disclaimed claims.
[Applicability Note: Subpart C (Post-Grant Review) generally applies to patents issuing from applications subject to first-inventor-to-file provisions of the AIA. In addition, the Chief Administrative Patent Judge may, in the interests-of-justice, order an interference commenced before September 16, 2012 to be dismissed without prejudice to the filing of a petition for post-grant review. See § 42.200(d) and the Leahy-Smith America Invents Act, Public Law 112-29, sec. 6(f)(3)(A).]
