VirnetX Scores Partial Win in Its Latest Federal Circuit Case with Apple
The United States Court of Appeals for the Federal Circuit last week affirmed-in-part, vacated-in-part, and remanded a decision of the Patent Trial and Appeal Board (PTAB) in the long-running case of VirnetX Inc. v. Apple Inc., Cisco Systems, Inc. The case relates to three inter partes reexaminations maintained by Apple and Cisco. The PTAB found that Apple could proceed with its reexaminations under the America Invents Act (AIA) and held that claims of VirnetX’s patent numbers 7,418,504 (“the ’504 patent”) and 7,921,211 (“the ’211 patent”) were unpatentable as anticipated/obvious. These patents were directed to methods for “establishing a secure communication link between [computers] over a computer network, such as the Internet” and are “built on top of the existing Internet protocol.” Basically, the patents claim a way to create secure communication links via domain name service (DNS) systems.
