The U.S. International Trade Commission (ITC) has upheld an import ban on Arista Networks ethernet switches which it thinks infringe Cisco’s patents.
The decision follows a complaint from Cisco filed in December 2014 about the switches, which are used in computer data centres and servers.
In a blog post on the company’s website on Monday, Cisco general counsel Mark Chandler said the import ban was to start on Tuesday. The ITC said Arista infringed three Cisco patents relating to managing and securing communications networks. The ruling excludes the import of Arista’s network devices, including its 7000 series of switches, which generates most of that company’s product revenue. It also prevents the sale of domestic supplies of the imported products.
Arista’s general counsel, Marc Taxay, said the company has redesigned the software in its switches and believes it is in “full compliance” with the ITC’s orders.
“Our primary focus remains the continued supply of non-infringing products to our customers,” he said.
Arista also said it would appeal to the U.S. Court of Appeals for the Federal Circuit. Arista has not received approval from the ITC for the redesigned products.
