Cisco Systems Inc did not infringe a patent holding company's wifi technology, a U.S. appeals court ruled on Monday, reversing a near $64-million judgment against the networking equipment maker in the long-running patent dispute. After eight years of litigation that also included a trip to the U.S. Supreme Court, the decision from the U.S. Court of Appeals for the Federal Circuit said Cisco was not liable for directly infringing or inducing others to infringe a patent held by Commil USA LLC on a way to help spread wireless signals over a large area, where multiple access points are needed. Cisco General Counsel Mark Chandler said the company was gratified by the ruling.
