The PTO issues new patents on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Lemi Technology, LLC, the first patent addresses techniques for providing a radio station at a user device using previously obtained DRM locked content. Assigned to Huawei (CN), the second patent addresses techniques for making system constraints of a specified permission in digital rights management.
8,825,552, "Providing a radio station at a user device using previously obtained DRM locked content," assigned to Lemi Technology, LLC.
Abstract
A system and method are disclosed for providing a radio station for playback at a user device using previously obtained Digital Rights Management (DRM) locked content for the radio station. In one embodiment, a radio station application and DRM locked content to be used by the radio station application are downloaded to a user device, which is preferably a mobile user device. The DRM locked content includes a number of DRM locked songs that may be used for the radio station. Thereafter, the radio station application obtains a playlist for the radio station, where the playlist for the radio station includes at least a subset of the DRM locked content provided to the user device for the radio station. Playback of the playlist for the radio station is then provided at the user device, and playback is reported to a remote service for royalty tracking.8,819,846, "Making system constraints of a specified permission in digital rights management," assigned to Huawei Technologies Co., Ltd. (CN)
Abstract
A method and a terminal device for making multi-system constraint of a specified permission in a digital rights. A rights object related to content object is obtained by an executing device. The specific permission descriptions of the rights object include system constraint descriptions of a plurality of systems of the same type. The executing device obtains a corresponding system information in the device according to the system constraint descriptions and compares the system information in the device with the system information in the system constraint descriptions, so as to judge whether there is any system permitted in system constraint descriptions. If yes, it determines to permit executing the specific permission for the content object; otherwise, it determines not to permit executing said specific permission for the content object.
