SAN DIEGO (AP) -- A federal judge ruled that Qualcomm Inc. violated a ban on wireless technology owned by rival chip maker Broadcom Corp., the companies said Thursday.
U.S. District Judge James Selna found that Qualcomm violated an injunction on use of chips for certain networks with high-speed Internet connections. He also ruled that Qualcomm was not paying royalties to Broadcom on phones with its QChat walkie-talkie feature.
Qualcomm said in a statement that it would appeal. It did not say how much the damages would cost.
A jury found in May 2007 that San Diego-based Qualcomm violated patents on Broadcom technology to help cell phones process video and walkie-talkie conversations and hand off calls between different networks.
Qualcomm is the world's largest maker of chips that run cell phones and is known for pioneering technologies. Broadcom, based in Irvine, is a relative newcomer to cell phones but it has scored several big legal victories against its bigger rival.
