LG Electronics on Tuesday said it has filed a lawsuit against Hisense with a US court, accusing the Chinese TV maker of infringing its patents.
The South Korean company claims that most of the Hisense TV models being sold in the US use four of its patented technologies. These include those that improve user interface and speed up Wi-Fi data transmission.
In the suit filed with the District Court of California, LG demanded Hisense stop using its patented technologies and pay damages.
Hisense was the world’s fourth-largest TV provider by sales in the first half of the year.
“The company will take stern measures against patent infringements in order to protect its intellectual property,” said Jeon Saeng-gyu, executive vice president at LG Electronics.
