Broadcom Fires Another Round Against Qualcomm
San Diego’s Qualcomm and Irvine’s Broadcom continue to exchange legal blows like a pair of prize fighters in a slugfest. In the latest round, Broadcom asked a federal judge in San Diego yesterday to declare that Qualcomm’s patents and patent licenses are unenforceable. Broadcom argues that Qualcomm’s sales and marketing practices constitute “patent misuse.” As a result, Broadcom contends the San Diego wireless giant has “exhausted” patents that control its post-sale use of products in the wireless communications industry. Qualcomm did not immediately respond to a request for comment.
