Arista Favored in ITC Initial Determination on Two of Four Features

SANTA CLARA, Calif.--(BUSINESS WIRE)-- Arista Networks (NYSE:ANET) today announced its response to the Initial Determination (ID) made by the Administrative Law Judge (ALJ) today in International Trade Commission (ITC) Investigation No. 337-TA-944. After Cisco Systems asserted six patents in the ‘944 investigation, Cisco dropped one patent and five remaining patents were asserted against four different features within Arista’s software, Extensible Operating System (EOS). In his ID, Judge Shaw found that Arista did not infringe two of the five patents thus clearing two of the four accused features.

“Our primary focus is the continued supply of products to our customers. We respect the administrative process and the tireless work of the ALJ in this preliminary decision. We strongly believe that we have not infringed any of the patents in the investigation and look forward to the final determination of the full commission in June 2016,” said Marc Taxay, Vice President, General Counsel of Arista Networks.

Cisco filed the ITC complaint against Arista on December 19, 2014. This is the first initial determination after a hearing that occurred in September of 2015 in Washington, DC. While still subject to review, Arista intends to fully address the infringement allegations with a new release of EOS available for software download in Q2 2016.
