“Federal Circuit reverses PTAB invalidation of patent for first time citing unreasonably broad claims construction,” The Patent Investor, June 22, 2105

In a ruling that may cheer patent owners and other critics of the inter partes review process, the Court of Appeals for the Federal Circuit ruled in the first ever reversal of a Patent Trial and Appeals Board ruling in an IPR filed by Microsoft Corp. against Proxyconn Inc. that the board’s claims construction was “unreasonably broad” and “legally incorrect.”

The ruling by Chief Judge Sharon Prost, Circuit Judge Alan Lourie and District Court Judge Rodney Gilstrap, who was sitting by designation, affirmed in part, reversed in part, vacated in part and remanded to the board its ruling which invalidated claims 1, 3, 6, 7, 9-10, 11, 12, 14, 22, 23 and upheld the validity of claim 24 of U.S. Patent No, 6,757,717.

The ‘717 patent relates to a system for increasing the speed of data access in a packet-switched network.
