Polypore legals put a brake on LG
Polypore has won an injunction against LG Chem preventing the Korean company from producing batteries containing its own version of ceramic coated separators.
Polypore’s subsidiary Celgard claims that LG Chem is infringing Celgard’s patent on ceramic-coated lithium-ion separators. The company has requested a preliminary injunction to prohibit the importation or sale of lithium-ion batteries in the US that contain LG Chem’s lithium-ion separators.
