Cisco slapped with $1.9 billion judgement in security patent lawsuit

Network World - Tue, 10/06/2020 - 2:56pm

Cisco this week lost a patent infringement case brought by security vendor Centripetal Networks and was hit with a $1.9 billion judgement.

A non-jury judgement from U.S. District Judge Henry Morgan determined Cisco infringed on four security patents related to encrypted traffic and packet filtering technology belonging to plaintiff Centripetal Networks. The award directs $755.8 million in actual damages, multiplied by 2.5 to reflect "willful and egregious" conduct from Cisco, the judge found. 

The award also includes past damages and a running royalty of 10% on the apportioned sales of the patented products for a period of three years, followed by a second three-year term with a running royalty of 5% on such sales, which could take damages from the case north of $3 billion, according to a Centripetal statement about the case.

"Amid global disruption, the key to survival for many companies has meant an accelerated shift to the cloud and, ultimately, bolting on security products in their data centers," said Sanjay Poonen, VMware's Chief Operating Officer, Customer Operations. "But legacy security systems are no longer sufficient for organizations that are using the cloud as part of their computing infrastructure. It's time to rethink security for the cloud. Organizations need protection at the workload level, not just at the endpoint."
