Qualcomm Inc. fired back at Irvine-based Broadcom Corp. Monday, filing a patent infringement lawsuit against the chipmaker in federal court in San Diego.
The suit alleges Broadcom infringed on seven patents held by San Diego-based Qualcomm related to wireless networking.
The litigation is the latest round exchanged between the two companies.
Last week, Broadcom filed a lawsuit against Qualcomm, alleging its licensing and other practices related to wireless technology and products violate antitrust laws.
Broadcom’s antitrust lawsuit, which was filed in the U.S. District Court for the District of New Jersey, follows patent infringement and fair trade complaints made by Broadcom against Qualcomm in May.
Broadcom said Qualcomm has abused the wireless technology standards-setting process, failed to license technology for mobile phone standards on fair, reasonable and non-discriminatory terms, amid other charges.
The chipmaker asked the court for monetary damages and seeks to bar what it calls Qualcomm’s “unfair business practices.”
