SEOUL, Nov 5 -- South Korean electronics maker LG Electronics Inc. said Tuesday it has filed a patent infringement suit against China's Hisense in the United States to protect its TV technologies, Yonhap News Agency reported.
LG said it filed complaints against American and Chinese branches of Hisense in a district court in California, claiming most of the Chinese firm's TVs sold in the US infringed upon its four TV patents.
The world's No. 2 TV maker said the TV patents are related to technologies aimed at improving user interface and speeding up data transfer speeds in wireless environments.
Hisense is the world's fourth-largest TV maker by volume, with slightly more than 7 per cent of the global market last year, according to market researcher IHS Markit. The Chinese company has a strong presence on its home turf and has expanded its share in the US and Europe.
