Display Technologies, LLC, an entity affiliated with prolific inventor and frequent plaintiff Leigh M. Rothschild, has pushed the number of defendants in its sole litigation campaign to nearly 50, suing GM (6:21-cv-00240), Harley-Davidson (6:21-cv-00242), Honda (6:21-cv-00242), Toyota (6:21-cv-00304), and Volkswagen (Porsche) (6:21-cv-00230) in March alone. Infotainment systems are targeted, with these defendants joining several other vehicle makers in the campaign, including Aston Martin, against which Display Technologies has sought entry of a default judgment, with Rothschild providing a supportive declaration with an estimated damages range for that case.
