This patent portfolio covers a comprehensive set of data-driven technologies for vehicle safety monitoring, accident detection, and insurance analytics across connected and intelligent transportation systems. The inventions protect systems that use sensor data, pattern recognition, and behavioral analytics to determine vehicle stationary status, monitor driver behavior, assess risk and emissions profiles, estimate accident damage and repair costs, and automatically detect and monitor accidents using ground-based and aerial surveillance. The portfolio also integrates navigation with insurance risk assessment to recommend safer routes and includes centralized vehicle diagnostic databases that support scalable communication between vehicles, client devices, and backend platforms. With early priority dates extending back to 2011 and broad applicability across automotive OEMs, insurers, telematics providers, fleet operators, and mobility platforms, the portfolio represents infrastructure-level IP and a compelling licensing or acquisition opportunity in the rapidly expanding connected-vehicle and vehicle-safety ecosystem.
