Federal Circuit Affirms PTAB Finding that Centripetal Patent Claims are Unpatentable as Anticipated

"The PTAB issued a final written decision finding that claim 1, which is representative for purposes of the appeal, is unpatentable on four grounds. Specifically, the PTAB found the claim anticipated by Cisco IronPort AsyncOS 7.1 for Web User Guide, referred to as IPUG, and anticipated by U.S. Patent Application 2012/0290829, known as Altman."

"Centripetal appealed the decision to the CAFC, challenging all grounds for finding the claims unpatentable. Writing for the CAFC, Judge Lourie addressed the ground that IPUG anticipates claim 1. Since the court affirmed the PTAB on that ground, the other grounds were deemed 'moot.'"

The U.S. Court of Appeals for the Federal Circuit upheld the PTAB's ruling that Centripetal Networks' patent claim was unpatentable due to prior art. The patent, which involves network security through efficient decryption, was challenged by Keysight Technologies. The PTAB found that the claim was anticipated by Cisco IronPort AsyncOS 7.1 and another patent application. Centripetal's appeal focused on the claim construction and the status of the prior art, but the CAFC's affirmation on one ground rendered the other arguments moot.
