    Abstract: A digital license sharing method, system and apparatus is provided for use in a digital rights management system. Usage rights in respect of digital content are transferred between content player devices or applications by associating with each player a status indication. Transfer is carried out by transmitting a request to obtain the usage rights from a player requiring usage rights to a player currently holding the rights. The transferring player sets a first status indication to indicate that it is no longer entitled to exercise the rights, and transmits a response to the requesting player to transfer the usage rights. The requesting player then sets a second status indication to indicate that it is henceforth entitled to exercise the rights. Methods and apparatus for creating transferable licenses are also provided that employ a sharable license format including a validated portion and an unvalidated portion.
