BASF sues Umicore over lithium-ion battery patent infringement

摘要

BASF confirmed to CW on Thursday that it and University of Chicago Argonne LLC had jointly filed lawsuits against Umicore (Brussels), and one of its customers, Makita, a Japanese toolmaker, alleging infringements of two US patents related to lithium-ion batteries containing nickel/manganese/cobalt (NMC) cathode materials. The suits were filed with the U.S. International Trade Commission (ITC) and a federal district court in Wilmington, Delaware in late February.
