US Patent 8224894 Zero-click sharing of application context across devices

A first client device performs a handoff operation to a second client device by transmitting application information, associated with a first application, to the second client device when the first client device is positioned within a predefined proximity of the second client device. The first application has a first client device user interface state when the handoff operation is performed. In response to receiving the application information from the first client device or system, the second client device or system executes a second application corresponding to the first application with an initial user interface state corresponding to the first client device user interface state.
