(Reuters) - Tesla sued Australian company Cap-XX in Texas federal court on Friday, claiming its supercapacitors used for storing energy in electric-vehicle batteries infringe two U.S. patents owned by a Tesla subsidiary.

Tesla CEO Elon Musk pledged in 2014 not to "initiate patent lawsuits against anyone who, in good faith, wants to use our technology." The company says the legal action comes in response to a lawsuit that Cap-XX originally filed against Tesla subsidiary Maxwell Technologies in 2019 for patent infringement.
