Route Guidance Systems LLC, an entity associated with Equitable IP Corporation, has sued DoorDash (1:22-cv-00176), Maplebear (d/b/a Instacart) (1:22-cv-00178), and Waitr (1:22-cv-00177) in the District of Delaware over mobile apps with navigation features for drivers of their respective delivery services. The sole asserted patent is broadly directed to providing route guidance to vehicles, with the NPE touting as advantages of the disclosed systems “that the transmission channel between the central computer and the vehicle need not be kept permanently open” and “that drivers can be informed as to the best routes for their vehicles to take to their respective destinations, in such manner that traffic congestion pertinent to the routes is taken into account”.
