Arista Writing Alternative EOS – Just in Case

Arista is developing an alternative version of EOS, its flagship operating system, in case it loses the intellectual property litigation brought by Cisco.

Cisco Systems Inc. (Nasdaq: CSCO) filed massive patent and copyright lawsuits against Arista Networks Inc. in late 2014, charging Arista unlawfully copied Cisco's command line interface (CLI) and other features that Cisco claims are its property. (See Cisco Slams Arista With Massive Patent & Copyright Suit.)

Arista suffered a setback in that lawsuit a few weeks ago, when the US International Trade Commission (ITC) issued an initial ruling favoring Cisco on key points. (See Judge Rules in Favor of Cisco Against Arista in ITC Complaint.)

The ITC will issue a final ruling June 2, followed by a Presidential Review Period to end Aug. 2.

Just in case it loses, Arista is working on a new version of its flagship EOS operating system that excludes the alleged Cisco intellectual property. But Arista is still committed to fighting on that score, company executives said on an earnings call Thursday. (See Arista: Cloud Drove 'Spectacular' Year.)

If the final decision is against Arista, then Arista will submit the alternative EOS to US Customs to get approval to import it to the US from its overseas manufacturers, executives said.

Customer support throughout the lawsuit has been "unwavering," CEO Jayshree Ullal said.

Executive Editor, Light Reading

San Diego-based Mitch Wagner is many things. As well as being "our guy" on the West Coast (of the US, not Scotland, or anywhere else with indifferent meteorological conditions), he's a husband (to his wife), dissatisfied Democrat, American (so he could be President some day), nonobservant Jew, and science fiction fan. Not necessarily in that order.

He's also one half of a special duo, along with Minnie, who is the co-habitor of the West Coast Bureau and Light Reading's primary chewer of sticks, though she is not the only one on the team who regularly munches on bark.

Wagner, whose previous positions include Editor-in-Chief at Internet Evolution and Executive Editor at InformationWeek, will be responsible for tracking and reporting on developments in Silicon Valley and other US West Coast hotspots of communications technology innovation.
