China’s No. 3 EV-Battery Maker Vows to Appeal CATL Patent Case

China Aviation Lithium Battery Technology Co. Ltd. (CALB) said that it will appeal a Fuzhou court’s patent infringement ruling that came out in favor of its larger rival Contemporary Amperex Technology Co. Ltd. (CATL), the latest development in a years-long legal battle between the two companies.

The Fuzhou Intermediate People’s Court ordered Hong Kong-listed CALB, China’s third-largest electric-vehicle (EV) battery-maker, to immediately stop selling products that violate CATL’s patents and pay the plaintiff 35.8 million yuan ($5.2 million) in damages, according to CALB’s Tuesday filing to the stock exchange.
