On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications address aspects of DRM. Assigned to the Electronics And Telecommunications Research Institute (KR), the first application discloses techniques relating to interoperability and DRM. Assigned to Microsoft, the second application discloses techniques for identifying DRM licenses.
20100071074, "Apparatus for executing interoperable digital rights management using contents device and method of performing operations between contents device and digital rights management tool for interoperable digital rights management," apparently assigned to the
Electronics And Telecommunications Research Institute (KR).
Abstract
Provided are an apparatus for executing interoperable digital rights management (DRM) using a contents device and a method of performing an operation between the contents device and a DRM tool for interoperable DRM, and more particularly, a method and apparatus for executing a DRM tool in various environments, regardless of the type of device or type of DRM tool, using an interfaced DRM executing apparatus including a DRM processor or a DRM tool agent.
20100070416, "Digital rights management license identification," assigned to Microsoft.
Abstract
A digital rights management license provides access to a content key that can be used to decrypt an encrypted digital content item. The digital rights management license also includes a policy that defines circumstances in which the content key is allowed to decrypt the encrypted digital content item. Further, the digital rights management license includes a license identifier. The license identifier is a digital fingerprint of at least a portion of the policy of the license.
