Paul, Weiss Obtains Federal Circuit Affirmance of PTAB Win Against Rosetta-Wireless

Paul, Weiss secured a win in the U.S. Court of Appeals for the Federal Circuit for our client, a leading consumer electronics company, against Rosetta Wireless. In 2015, Rosetta Wireless sued our client in district court, asserting infringement of a patent directed to a wireless server. In 2016, our client filed two inter partes reviews in the Patent Trial and Appeal Board (PTAB), challenging the validity of that patent. The district court litigation was stayed pending the outcome of the PTAB proceedings, and in 2017, the PTAB ruled in favor of our client, invalidating every challenged claim of Rosetta’s patent. Rosetta appealed that ruling to the Federal Circuit, which heard oral argument earlier this year. In its decision, the Federal Circuit affirmed the PTAB’s ruling across the board in our client’s favor. This decision therefore renders invalid every claim of Rosetta’s patent asserted in the district court.   

The Paul, Weiss team included litigation partner Steve Baughman and counsel Megan Raymond, who argued the appeal.
