Diamond Coating Technologies, LLC v. Hyundai Motor America et al DC CAFC

Diamond Coating Technologies, LLC (DCT) has hit reset on two separate cases that it filed against Hyundai and Nissan to kick off this litigation campaign in September 2013 . A California district court dismissed those earlier actions without prejudice on April 1, 2015 for lack of standing. Following a considerable period of discovery, as well as a claim construction ruling (adopting many of DCT’s proposed constructions), Judge Mariana R. Pfaelzer ruled that Sanyo, the original assignee, retained sufficient rights in the patents-in-suit to require joinder to DCT’s cases. Sanyo would not join, and the suits were dismissed.
