Administrative Law Judge Endorses Arista's Redesign in ITC Initial Determination

Arista Networks ANET today announced that the Administrative Law Judge (ALJ) at the International Trade Commission (ITC) has issued an Initial Determination (ID) in the ITC enforcement proceeding brought by Cisco Systems 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.

"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^th," said Marc Taxay, Senior Vice President and General Counsel of Arista Networks. "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."

The ALJ's decision on the enforcement proceeding follows the U.S. 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.
