Last month, Display Technologies, LLC, an entity affiliated with prolific inventor and frequent plaintiff Leigh M. Rothschild, sued Arkray (0:21-cv-02458) and Nonin Medical (0:21-cv-02456) in the District of Minnesota and BMW (6:21-cv-01214) in the Western District of Texas over the support of wireless connectivity in a wide range of products (i.e., blood glucose meters, pulse oximeters, and automotive infotainment systems, respectively). At issue in each complaint is a single patent generally related to transferring media files wirelessly between devices. Since launching its sole litigation campaign in 2015, Display Technologies has sued 60 defendants and asserted two patents (each naming Rothschild as its inventor).
