First Reversal of PTAB in IPR
Yesterday, in Microsoft Corp v. Proxyconn Inc. (here), the Court of Appeals for the Federal Circuit (CAFC) reversed an Inter Partes Review (IPR) determination USPTO’s Patent Trial & Appeal Board— a first. (The decision also affirmed-in-part, vacated-in-part, and remanded-in part) The Court found that the Board’s construction of several key terms to be unreasonably broad. The IPR is now remanded for further Board proceedings on a narrowed construction. In this sense, apart from historical significance, the decision is unremarkable.
