Post Grant Review

Post grant review is a trial proceeding conducted at the Board to review the patentability of one or more claims in a patent on any ground that could be raised under § 282(b)(2) or (3). Post grant review process begins with a third party filing a petition on or prior to the date that is 9 months after the grant of the patent or issuance of a reissue patent. The patent owner may file a preliminary response to the petition. A post grant review may be instituted upon a showing that, it is more likely than not that at least one claim challenged is unpatentable. If the proceeding is instituted and not dismissed, a final determination by the Board will be issued within 1 year (extendable for good cause by 6 months). The procedure for conducting post grant review took effect on September 16, 2012, and generally applies to patents issuing from applications subject to first-inventor-to-file provisions of the AIA.
