On Thursdays the USPTO publishes new patent applications. Both of today's Spotlight Applications address various aspects of DRM. The first application discloses interoperable DRM systems, no assignee given. Assigned to Microsoft, the second application discloses portable digital rights for multiple devices.
20090013185, "Compatible system of digital rights management and method for operating the same," no assignee given.
Abstract
Disclosed is a compatible system of digital rights management which enables the reproduction of the same contents between apparatuses each employing a different digital rights management system. The compatible system of digital rights management comprises: a user server including a first authentication document of a first apparatus; a second apparatus connected to the first apparatus and outputting a contents request signal and a second authentication document to reproduce substantially the same contents; and a provider server forming a virtual safe channel with the user server based on the contents request signal to receive the first authentication document, and generating first and second licenses encrypted through the first and second authentication documents to transmit the same to the second apparatus.
20090012805, "Portable Digital Rights for Multiple Devices," assigned to Microsoft.
Abstract
Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.
