Cisco rulings sink Arista stock

Arista reportedly suffered a setback in its litigation with Cisco that caused its stock to drop almost 6% this week. According to Investor’s Business Daily, International Trade Commission attorneys determined Arista infringed on three Cisco patents, causing the company’s stock to drop 5.6% Thursday.

Arista stock dropped 11% today on the ruling.

Cisco filed suit against Arista back in December, claiming copyright and patent infringement. Suits were filed in both federal court and the ITC.

The ITC action was intended to block Arista from importing and selling products in the United States that Cisco alleged infringed on its patents. It was an attempt to expedite the injunction of Arista product while Cisco patent and copyright infringement suits against the company wind their way through the court.

In July, a federal judge dismissed Cisco’s indirect infringement claims against Arista, a complaint that accompanied a patent and copyright infringement case. Just after this claim, Arista introduced its EOS+ operating system and Cisco then amended its claim to demand extra penalties for “willfulness” infringement.

The judge then ordered Cisco to amend its claim to make a stronger case that EOS+ was a new product and not a new version of an existing product.

Cisco provides an update on all of the litigation with Arista here. Here is Arista’s statement on the ITC ruling and on the cases overall:
