Hong Kong-listed battery maker CALB said on October 18 that it has filed lawsuits in courts in China’s Hubei and Jiangsu provinces against CATL and its subsidiaries, alleging infringement of four battery-related patents.
CALB is seeking damages totaling CNY 1.007 billion in lawsuits against CATL, its subsidiary Sichuan Times New Energy Technology, Tesla’s sales service company in Wuhan, Zeekr’s sales department in Changzhou and Avatr’s Wuhan division. Notably, this is the first time CALB has filed a patent infringement lawsuit against CATL.
The allegations relate to patents critical to battery structure, assembly techniques, battery pack design, cooling systems and integration technologies, including innovations in battery devices and cooling systems for liquid-cooled modular units. The largest claim within the lawsuits relates to liquid-cooled modular battery systems, with CALB seeking damages of CNY 560 million.
In its filing, CALB demanded that CATL and related entities immediately address the alleged violations and pay compensation for economic damages and legal costs.
