Jury Favors Arista-Landmark Win for Networking Industry

SANTA CLARA, Calif.--(BUSINESS WIRE)-- Arista Networks (NYSE: ANET) today announced that a U.S. jury in the Northern District of California has found that Arista is not liable for copyright infringement related to Arista’s use of a small number of commands similar to those found in Cisco’s Command Line Interface (CLI). As a result of this ruling, Arista owes no damages to Cisco.

“We would like to thank the jurors and Judge Freeman for their tireless efforts. Today’s verdict represents an important victory not only for Arista but for the entire industry,” said Marc Taxay, Senior Vice President and General Counsel of Arista.

The jury also found that Arista did not infringe the single patent remaining in the case as well as Cisco’s asserted copyrights in its user manuals.
