Federal Circuit Issues Contentious Order Not to Review En Banc PTAB’s Claim Construction Standard For IPR Proceedings
On Wednesday, July 8, 2015, the Federal Circuit in a contentious 6-5 vote denied en banc review of its first opinion in connection with PTAB decision in an IPR proceeding, In re Cuozzo Speed Technologies, LLC. As previously discussed, Cuozzo appealed the PTAB’s invalidation of three claims of U.S. Patent No. 6,778,074 on the grounds that the PTAB in its IPR decision improperly applied the “broadest reasonable interpretation” standard on claim construction, a standard that is traditionally applied to patent prosecution. A 2-1 panel for the Federal Circuit affirmed the application of this standard in view of the fact that the USPTO has been using this standard for more than a century and the majority’s conclusion “that Congress implicitly adopted the broadest reasonable interpretation standard in enacting the AIA.” The court also found that this was further supported by the statute giving the PTO Director the ability to establish the standards for establishing and governing inter partes review.
