CATL alleges that the batteries made by CALB infringing on said intellectual property rights have already been installed in “tens of thousands” of vehicles, meaning this could get expensive. CALB also added that the batteries it supplies to customers have passed assessments to make sure they do not violate others’ intellectual property rights.

Update 16 December 2022

After the Chinese battery cell giant CATL sued its smaller rival CALB last year for alleged infringements of its intellectual property, the first court decisions have now been made. According to Chinese media, CATL has won two out of five individual lawsuits in the first instance. CALB must pay damages and, in one of the cases, also stop selling products that infringe CATL’s patent rights. However, CALB has already announced that it will appeal.
