Chinese battery cell manufacturer Contemporary Amperex Technology (CATL) has sued its smaller rival China Lithium Battery Technology (CALB) for alleged infringement of its intellectual property. The latter denies the allegations.

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.
