Cisco Wins Centripetal Patent Case that Led to $2.75 Bln award

A federal judge in Virginia has rejected cybersecurity company Centripetal Networks' patent infringement claims against Cisco Systems (CSCO.O) in a multi-billion-dollar fight over network-security technology.

A different judge in the same court, U.S. District Judge Henry Morgan, had awarded Centripetal $2.75 billion in the case in 2020, marking the largest patent damages award in U.S. history. A federal appeals court later overturned that award on ethics grounds because Morgan's wife owned Cisco stock.

Morgan had died in the interim, and the appeals court directed that the case be heard by a new judge. U.S. District Judge Elizabeth Hanes held new hearings in the case and ruled on Monday that Cisco did not infringe the patents.

Reston, Virginia-based Centripetal sued Cisco in 2018, claiming Cisco's routers, network-security software and other products infringed patents related to Centripetal's technology for blocking security threats from entering a computer network.

Morgan ruled for Centripetal in 2020 after a non-jury trial. He awarded Centripetal $1.9 billion in damages, plus royalties that Cisco said increased the total to more than $2.7 billion.

Morgan told the companies before issuing his ruling that he had learned his wife owned 100 shares of Cisco stock worth $4,688. He said that he was unaware of the stock during the trial and that it had not influenced his handling of the case.
