Apple has brought a declaratory judgment (DJ) action against Fundamental Innovation Systems International LLC, an NPE with active campaigns in the US and Europe, and its corporate parent, Fundamental Innovation Systems International Holdings LLC (collectively, “FISI”). Apple’s DJ complaint (3:19-cv-00638), filed on February 5 in the Northern District of California, seeks a judgment of noninfringement for three categories of products that include certain adapters, mobile devices, and wearables. The 12 patents-in-suit originated with BlackBerry and include a group of USB charging patents that FISI has asserted in a campaign hitting Huawei, LG Electronics (LGE), Samsung, and ZTE. They were among the roughly 200 patent assets that BlackBerry assigned to FISI in a late 2015 transaction—a multi-million dollar deal, according to public records, that was embroiled in strife and gamesmanship.
