With apparent backing by a litigation funder, Avant Location Technologies LLC has filed suit against Generac (ecobee) (2:23-cv-00354) in the Eastern District of Texas, asserting two patents generally related to a system for providing “presence related services” to a designated “special area” through a linked mobile station. The defendant is accused of infringement through the provision of smart home devices including certain cameras, sensors, and thermostats, as well as related devices. At issue are certain location-tracking tools or functionalities (e.g., Arm/Disarm, geofencing, and Home/Away detection).
