Stragent LLC has revived a litigation campaign that has lain dormant for over two years, filing three nearly identical complaints against automakers BMW (6:16-cv-00446), Daimler (6:16-cv-00447), and Geely (Volvo) (6:16-cv-00448). The two asserted patents (8,209,705; 8,566,843) issued in 2012 and 2013 as continuations of an earlier patent (7,802,263) that Stragent asserted in litigation between February 2011 to November 2013 against suppliers of microcontrollers and/or related software to auto manufacturers. The patents generally relate to communicating information (e.g. software updates) across networks of different type. Stragent’s infringement allegations focus on the defendants’ purported migration to AUTOSAR (AUTomotive Open System ARchitecture), a standardized system of interfaces between automotive network technologies.
