RCT v. Microsoft (D. Ariz.; Fed. Cir.)

Klarquist helped our client Microsoft win on summary judgment in the District Court of Arizona that Plaintiff RCT’s twelve asserted patent claims were invalid. The Court of Appeals for the Federal Circuit affirmed the invalidity of eight of those claims that cannot be backdated to an earlier patent application because the claims lack written description support in the earlier application. The Federal Circuit remanded the remaining four patent claims to the District Court.
