Portions of Trina Solar TOPCon patents deemed unpatentable

USPTO Patent Trial and Appeal Board ruled portions of Trina Solar's TOPCon patents (U.S. Patent Nos. 9,722,104 and 10,230,009) unpatentable, finding Runergy and Canadian Solar not infringing. Adani Green Energy previously settled with Trina. U.S. International Trade Commission terminated Trina's Section 337 investigation seeking import ban. First Solar filed separate Section 337 investigation against Trina Solar, Canadian Solar, Runergy and Adani over TOPCon patents, which remains ongoing.
