A federal court jury today sided with Arista in a copyright infringement case filed by Cisco, Reuters is reporting.

Cisco had sought about $335 million in damages from Arista, claiming the newer company stole 500 copyrighted commands in its Command Line Interface (CLI).

The jury in U.S. District Court in San Jose, California, today ruled that Arista had, in fact, infringed Cisco's copyrights. However, the jury awarded Cisco no monetary damages. The jury also found that Arista did not infringe a Cisco patent.

While Cisco had argued that Arista stole its CLI commands, Arista responded that other vendors also use the commands, and they haven’t been sued.

In today’s verdict, jurors said Arista proved that other factors besides Cisco’s creativity determined the design of Cisco’s commands, reports Reuters.

In two other legal cases filed by Cisco with the U. S. International Trade Commission, the ITC has ruled that Arista did violate Cisco patents. However, Arista has been able to avoid import bans in the first case by creating product workarounds. And it’s plotting a similar strategy in the second ITC case.

Arista’s stock is up about 3 percent this afternoon, while Cisco’s stock is flat.
