Arista claims latest win in patent fight v Cisco

Arista Networks is claiming another victory in its long-running intellectual property battle with larger rival Cisco Systems after a judge ruled that Arista redesigned its ethernet switches so that they do not infringe on a patent owned by Cisco.

Arista said the Administrative Law Judge (ALJ) at the International Trade Commission (ITC) issued an initial determination (ID) in the ITC enforcement proceeding brought by Cisco against Arista.

“In the ID, the ALJ found that Arista’s sale of its redesigned switch products does not violate the cease and desist order issued by the ITC with respect to U.S. Patent No. 7,162,537 as part of the underlying ITC Investigation No. 337-TA-944,” said Arista.

Arista Networks general counsel Marc Taxay said: “This is an important step in bringing the 944 investigation to conclusion and we look forward to the commission’s final determination, which is currently scheduled to issue no later than September 20.

“We once again appreciate the tireless work of the ALJ in rendering the initial determination and are pleased with his findings that our redesigned products do not infringe the ‘537 patent and fully comply with the ITC’s order.”

Arista said the ALJ’s decision on the enforcement proceeding follows the US Customs and Border Protection (CBP) rulings on November 18, 2016 and April 7, 2017 that Arista’s redesigned products do not infringe the ‘537, ‘145 or ‘592 patents implicated in the 944 investigation and that Arista could again resume importation of its redesigned products into the United States.
