Amperex Technology (ATL) (1:23-cv-00272) has asked the Eastern District of Virginia for a declaratory judgment of noninfringement of a single patent held by Semiconductor Energy Laboratory Co., Ltd. (SEL) through the provision of certain lithium ion batteries. The patent generally relates to a lithium battery with an electrode that incorporates certain material, with Amperex pleading that SEL “has communicated with ATL representatives and via other channels without the protection of an NDA, including in January and February 2023, to discuss the licensing of SEL patents”, including the patent now in suit. The new complaint drops as SEL’s April 2023 trial in a Central District of California case that it filed against TCL back in March 2021 faces a delay.
