NEW YORK Dec 9 Arista Networks Inc
used rival Cisco Systems' network device technology in
its ethernet switches without permission, a U.S. trade judge
ruled on Friday, handing Cisco yet another win in a sprawling
legal battle over patents between the two companies.
The judge, MaryJoan McNamara of the U.S. International Trade
Commission in Washington, said that Arista had infringed two
patents owned by Cisco. The commission in June, in a separate
case, ordered an import ban on Arista's products that infringed
several other Cisco patents.
