In its litigation campaign over former BlackBerry patents, Fundamental Innovation Systems International LLC (FISI) has upped the number of defendants from three to four and the number of patents-at-issue from five to eight. FISI’s new complaint against Samsung (2:17-cv-00145) asserts all five patents (7,239,111; 7,834,586; 7,893,655; 8,232,766; 8,624,550) already in campaign as well as three patents (6,936,936; 7,791,319; 8,541,983) new to the litigation. Rights in all of the patents, which generally relate to charging the battery of a mobile device (most of them explicitly by using a USB connection to “fast charge” it) were received from BlackBerry as part of a November 2015 transaction involving over 50 patent assets. In its complaints, FISI characterizes itself as “responsible for protecting and licensing seminal BlackBerry innovations in the field of USB charging”, and the accused products are mobile, charging, and other devices that allegedly make such use of a USB connection.
