US Patent 9548998 Asynchronous communication system architecture

Data is asynchronously provided to a participant of a conversation. A temporal model is maintained for each of a plurality of client devices associated with the conversation. A temporal model describes a state of an associated client device. Data for sending to a client device is identified based on conversation context information describing a context of a conversation participant associated with the client device. A determination of whether to send the identified data to the client device is made based on the temporal model associated with the client device. The temporal model associated with the client device is updated based on the determination.
