Tracking device location identification
First Claim
1. A method for determining a last known location of a tracking device, the method comprising:
- receiving, by a tracking server from a first mobile device, a disconnection event indicating that a first tracking device has disconnected from the first mobile device, the disconnection event comprising an identifier of the first tracking device, a location of the first mobile device when the first tracking device disconnected from the first mobile device, and a first timestamp of the disconnection;
receiving, by the tracking server, a set of location updates, each location update received in response to a mobile device detecting the first tracking device and comprising a location of the mobile device when the mobile device detected the first tracking device, the identifier of the first tracking device, and a timestamp of the detection;
determining, by the tracking server, a last known location of the first tracking device based on the disconnection event and one or more location updates selected out of the received set of location updates based on the timestamps associated with each of the selected one or more location updates.

Abstract
A last known location of a tracking device can be determined by using location information received at a tracking system. A disconnection event is received at the tracking system indicating that a tracking device has disconnected from a mobile device. In response, the tracking system can generate a last known location for the tracking device. Other relevant location updates, such as recent locations of the mobile device or locations of other mobile devices that connect to the tracking device are collected and associated with the disconnection event. Based on the location updates, a last known location of the tracking device can be computed and stored.
