As we reported yesterday, the U.S. Patent and Trademark Office (USPTO) Director Kathi Vidal issued a memorandum on the “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation” clarifying current Patent Trial and Appeal Board (PTAB) practice on discretionary denials of inter partes review (IPR) and post grant review (PGR) proceeding institutions. The memo and corresponding press release explain that the PTAB “will not deny institution of an IPR or PGR under Fintiv (i) when a petition presents compelling evidence of unpatentability; (ii) when a request for denial under Fintiv is based on a parallel ITC proceeding; or (iii) where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.”
