Jury verdict for Arista

A jury handed Arista Networks Inc a major win in a wide-ranging legal battle against Cisco, ruling that Arista owed no damages over Cisco’s claims of copyright infringement.

The jury in a San Jose, California federal court also found that Arista did not infringe a Cisco patent. The verdict is the latest in sprawling litigation between Cisco, a major networking equipment company, and Arista, a fast-growing rival. Cisco had been seeking roughly $335 million in damages from Arista for copyright infringement.
