Telecommunications chip maker Broadcom Corp. said Wednesday an appeals court upheld a May 2007 jury verdict that rival Qualcomm Inc. violated two of its patents. A third patent was found to be invalid.
A jury in Santa Ana, Calif., had found that Qualcomm violated patents on Broadcom technology used to help cell phones process video and walkie-talkie conversations and hand off calls between different networks.
The patent related to video encoding technology was the one the appeals court later ruled to be invalid.
Broadcom also said the U.S. Court of Appeals for the Federal Circuit rejected Qualcomm's request for a new trial.
Alex Rogers, Qualcomm senior vice president and legal counsel, said the results were "mixed" for the company.
"Obviously we are pleased that one of the three patents was (held invalid)," he said.
Irvine, Calif.-based Broadcom's shares rose $1, or 5.4 percent, to $19.39. The stock has traded between $16.38 and $43.07.
San Diego-based Qualcomm's shares slid 62 cents at $45.29.
