Rothschild Location Technologies LLC (RLT Texas) added three more defendants to its location services campaign, asserting a single patent (8,606,503) against GoFleet (6:15-cv-00902), Imarda (6:15-cv-00901), and Smart Fleet (6:15-cv-00903). RLT Texas is controlled by individual inventor Leigh M. Rothschild. The ‘503 patent generally relates to transmitting location information to a positional device, and the complaints accuse the defendants of infringement through their use of GPS tracking. All of the over 15 Texas cases have either been quickly dismissed (the vast majority with prejudice, some after earlier court documents reference settlement) or remain open in pleadings.
