According to "South Korea Herald" Beijing time on November 22 reported that South Korean battery maker LG Chem confirmed on Tuesday that the company has filed a lawsuit in the United States accused Chinese rival ATL of infringing its technology patents.
Last month, LG Chem and its Japanese partner Toray filed a lawsuit in ATL at Michigan, which owns a number of plants in Michigan to produce batteries for customers such as General Motors and Chrysler.
LG accused ATL of infringing three of its U.S. patents on a part of the battery called a "bulkhead." Since 2015, LG Chemical has outsourced the production of the bulkhead to Toray.
LG Chem also called on the U.S. International Trade Commission to ban the import of ATL batteries, saying ATL 'flooded the U.S. market with cheap, low-quality batteries made entirely in China. "LG Chem said unlike the company that built the plant in Michigan to hire a large number of Americans, ATL 'is basically a zero investment in the U.S. economy.'
It is reported that the battery affected by the case is used for a variety of electronic products, including DJI UAV and OPPO smart phones.
LG Chem said it sued ATL simply because the company violated its patents.
'We brought this suit just because we found ATL infringes some of our technology patents and we want to protect our patents and intellectual property rights,' said one executive at LG Chem.
