Finnegan secures summary judgment of invalidity for client Toshiba

The Central District of California entered judgment invalidating all claims that Lochner Technologies—a non-practicing entity—had asserted against Finnegan client Toshiba America Information Systems, Inc.  On summary judgment and before the parties engaged in costly discovery, the judge found the claims invalid for lacking a sufficient written description and for failing to claim what the inventors regarded as their invention.  The court previously issued a favorable claim construction ruling that eliminated most accused products from the case.  The invalidity ruling disposed of the remaining issues.  Initially, Lochner had asserted its patent against twenty-two defendants.  Most settled, but Toshiba and Vizio, Inc. fought until the invalidity ruling brought the district court case to a close.
