Hyundai and Kia (6:25-cv-00016) are the latest defendants to be added to the sole litigation campaign of inventor-backed Proxense, LLC, launched in June 2019 with a case against Nordstrom. The four patents-in-suit, two of which are newly asserted in litigation, are broadly directed to the use of a “personal digital key” to generate access to a computing device and/or resources. The defendant is accused of infringement through the provision of automobiles that support digital key technologies (i.e., Digital Key 2).
