An International Trade Commission administrative law judge on Tuesday made an initial determination that Arista Networks infringed in three out of five Cisco Systems Inc. patents, part of a Cisco complaint against Arista filed in December 2014. The judge cleared two of Arista's software features out of four in question, Arista said in a statement. "We strongly believe that we have not infringed any of the patents ... and look forward to the final determination" in June, the Santa Clara, Calif., company said. In a blog post on Cisco's website, Cisco's top lawyer, Mark Chandler, said "Arista can no longer support claims ... that they created products 'from a clean sheet of paper.'" Arista shares rose 0.2% in late trading Tuesday after ending the regular session down 2.7%. Shares of Cisco rose 0.1% after ending the session down 2.7% as well.
