Cisco loses patent appeal

Supreme Court rules in favor of patent holder Commil

The U.S. Supreme Court this week ruled against Cisco’s appeal of a patent infringement claim against the company dating back to 2011.

On a 6-2 vote, the court threw out a ruling by the U.S. Court of Appeals for the Federal Circuit in favor of Cisco against patent holding company Commil. Commil was awarded $64 million after suing Cisco for patent infringement and induced patent infringement in a trial that was reordered due to anti-Semitism.

Cisco vowed to appeal that ruling but the Supreme Court this week ruled that Cisco's belief that the patent was invalid was not a legitimate defense.

Cisco expects a retrial.

The ruling "simply eliminates one of many defenses available to Cisco, which looks forward to retrial of the case,” said Cisco attorney Seth Waxman, to Reuters.
