Valve has filed a second amended complaint in the Western District of Washington case (2:23-cv-01016) begun last July against Leigh M. Rothschild and three associated entities Display Technologies, LLC; Patent Asset Management, LLC; and Rothschild Broadcast Distribution Systems, LLC (RBDS), together with Rothschild counsel Meyler Legal, PLLC and its principal Samuel Meyler. The defendants have refiled a motion to dismiss the complaint in which they argue that Valve is “attempting to make ‘a mountain out of a mole hill’ by characterizing a simple clerical error as some sort of legal malfeasance” under the state’s “Patent Troll Protection Act”. Meanwhile, venue challenges in Eastern District of Texas cases filed this past September by three other Rothschild plaintiffs—Quantum Technology Innovations, LLC; Social Positioning Input Systems, LLC (SPIS); and Symbology Innovations, LLC—are ripening.

Social Positioning Input Systems, LLC (SPIS), one of many NPEs controlled by prolific inventor Leigh M. Rothschild, has sued ClearPathGPS (2:21-cv-00519) in the Central District of California, Lytx (3:21-cv-00104) in the Southern District of California, and Particle Industries (3:21-cv-00464) in the Northern District of California. The sole patent-in-suit generally relates to transmitting the location information of a positional device, with the defendants accused of infringement through the provision of vehicle fleet tracking systems. Rothschild ended last year near the top of the list of frequent NPE plaintiffs, second only to Texas monetization firm IP Edge LLC.
