LONDON In what could be a titanic struggle between two communications heavyweights, fabless communications chip company Broadcom Corp. has filed multiple lawsuits against cellular communications technology provider Qualcomm Inc. Broadcom alleges that Qualcomm has infringed 10 Broadcom patents related to wired and wireless communications and multimedia processing technologies.
In two complaints filed Wednesday (May 18) in the U.S. District Court for the Central District of California, Broadcom is seeking unspecified monetary damages from Qualcomm as well as a permanent injunction barring the manufacture and sale of Qualcomm's core suite of baseband and RF chips. The suits target Qualcomm's multimedia, enhanced and convergence platform chips along with its QChat voice-over-IP technology for cellphones, which Broadcom alleges infringe its patents.
Broadcom said Thursday it has also filed a complaint with the U.S. International Trade Commission (ITC) alleging that Qualcomm has engaged in unfair trade practices by importing chips and other products that it claims infringe five Broadcom patents.
Broadcom is seeking an ITC investigation into Qualcomm's infringing imports and ultimately a ban the importation of relevant Qualcomm devices into the U.S., Broadcom said. Broadcom is also seeking a bar on further sales of Qualcomm products that have already been imported.
"Broadcom was an early pioneer in a broad range of wired and wireless communications and multimedia technologies, and has enabled the convergence of digital video, digital audio, Wi-Fi, Bluetooth, storage, voice-over-Internet Protocol and adaptive coding technologies in many markets, including advanced, multi-function cellular products and services," Scott McGregor, Broadcom's president and CEO, said in a statement. "We believe that Qualcomm's current and next generation cellular baseband and radio frequency product lines infringe a number of our patents."
Broadcom said it expects that the ITC investigation will commence in late June, and that the case will be heard early in 2006. Broadcom's intellectual property portfolio currently includes 955 U.S. patents and over 3,200 additional U.S. patent applications, the company said.
