Abstract
The present invention provides distributed communication services based on a presence technology platform. Presence messaging and communication techniques allow a variety of communication agents to cooperate with one another to provide distributed services. Essentially, the messaging between the agents is used to facilitate media sessions and update participating devices of state changes bearing on providing the services. In one embodiment, each of the participating devices is associated with a logic entity, referred to as a presentity, which subscribes to notification services for the other participating devices. When a state change occurs on any one of the participating devices, the corresponding presentity notifies the other devices of the state change. As such, each participating device knows the status of the other participating devices via the presentities and can systematically determine when and how to provide services based on its current state and the current state of the other participating devices.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
