Viewpoint IP LLC, an IP Edge LLC plaintiff, has doubled the number of defendants in one of the two campaigns begun this year over patents from a second portfolio acquired from Monterey Research, LLC, last November. The NPE accuses DENSO (1:21-cv-00270), Infinera (1:21-cv-00271), Renesas (6:21-cv-00369), and Semtech (1:21-cv-00269) of infringing a single patent, generally related to fabricating a transistor using a “sacrificial emitter”, through the provision of certain bipolar transistors (Renesas) or products that allegedly incorporate them, including radar sensors (DENSO), network aggregators (Infinera), and network multiplexer chips (Semtech).
