In December 2016, Fundamental Innovation Systems International LLC (FISI) began targeting mobile device manufacturers with a series of Texas lawsuits asserting USB charging patents acquired from BlackBerry in late 2015. As FISI’s litigation proceeds in the US, documents recently filed in the District Court of Mannheim now indicate that the German leg of the NPE’s campaign also remains active, with hearings held earlier this month in cases against Samsung and electronics retailers Cyberport GmbH and notebooksbilliger.de AG. Other filings show that the asserted patents have been targeted in a variety of invalidity proceedings, both in Germany and before the European Patent Office (EPO).
