On Thursdays the USPTO publishes new patent applications. Both of today's Spotlight Applications address aspects of DRM. The first application discloses techniques for updating time information of a DRM device, no assignee given. The second application discloses techniques for multilevel distribution of digital content, assigned to Sony Ericsson Mobile Communications.
20080195869, "Method and system for updating time information of a DRM device," no assignee given.
A method and system for updating time information of a digital rights management (DRM) includes a time server transmitting a time information message to a consumer electronics (CE) device, the CE device transmitting the time information message to a digital rights management DRM device when the CE device receives the time information message from the time server, and the DRM device updating a present time of the DRM device based on the time information message when the DRM device successfully performs authentication with respect to the time information message which has been transmitted from the CE device.
20080195546, "Multilevel distribution of digital content," assigned to Sony Ericsson Mobile Communications AB (SE).
Disclosed is a system and method for earning award points for distributing electronic digital content between electronic equipment. Digital content (protected and un-protected) is stored on a remote distribution server for transmission to receiving electronic equipment (e.g., portable communications devices including mobile telephones, computers, etc.). The digital content generally includes a header having one or more digital rights management fields for allowing access to the digital content based upon a content provider's preferences. Prior to the operator of the receiving electronic equipment distributing the digital content to one or more other electronic equipment, a unique identifier associated with the receiving electronic equipment is inserted in one or more of the digital rights management fields of the digital content. The digital content is then distributed containing the unique identifier. An identification associated with the digital content and the unique identifier associated with the receiving electronic equipment is transmitted to a provider upon distribution of the license for maintaining at least an awards program based on distribution of the digital content.
