New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Intertrust, the first of today's patents concerns techniques for governing derived electronic resources. Assigned to Microsoft, the second patent concerns techniques for using policies for digital rights management that enable distribution of full-function versions of applications that, while fully functional, have functions limited by an associated policy.
9,589,110, "Information security systems and methods," assigned to Intertrust Technologies.
Systems and methods for governing derived electronic resources are provided. In one embodiment, a digital resource is associated with one or more rules and a set of one or more computations, wherein the rules correspond to one or more conditions for accessing the digital resource and the computations operate upon the digital resource in order to provide a specific view of the digital resource that differs from the digital resource.
9,589,114, "Policy for digital rights management," assigned to Microsoft.
This document describes policies for digital rights management that enable distribution of full-function versions of applications that, while fully functional, have functions limited by an associated policy. A policy may be replaced or updated, thereby enabling use of previously limited functions without distribution of another version of the application.
