The complaint, filed in the US District Court for the Central District of California on 3 March, alleged that LG infringed five Broadcom patents relating to semiconductor components, decoder systems, video graphics and video recording.
LG infringed the patents through sale of LED and smart TVs, according to Broadcom.
Broadcom said in the complaint that its “continued success” depends on its research and development, in which it invested $2.7 billion in 2016 alone.
“Broadcom relies on the patent system as an important part of its intellectual property programme to protect the valuable technology and inventions resulting from this research and development. As of 30 October 2016, Broadcom Limited had approximately 27,640 US and other patents and approximately 3,020 US and other pending patent applications.”
Broadcom added: “The infringing activities by [LG] have caused and will continue to cause irreparable injury to Broadcom for which there exists no adequate remedy at law.”
