The PTO issues new patents on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Amazon, the first patent addresses digital rights management techniques for applications. Assigned to Microsoft, the second patent addresses techniques for issuing a publisher use license off-line in a digital rights management (DRM) system.
8,719,586, "Digital rights management for applications," assigned to Amazon.
This disclosure describes systems and associated processes that provide digital rights management for applications. In some embodiments, these system and processes couple DRM protection with individual applications, rather than with a centralized service. For instance, these systems and processes can be implemented in the context of an application store or distribution service that distributes applications for purchase or for free to user devices. Developers can submit applications to the application distribution service for distribution to end users. In response to receiving an application from a developer, the application distribution service can modify the application to include DRM features. The application distribution service can accomplish this modification without input from or the knowledge of the developer. The DRM features included in the modified application can prevent or otherwise reduce copying or modifying of the application.
8,719,171, "Issuing a publisher use license off-line in a digital rights management (DRM) system," assigned to Microsoft.
A publishing user publishes digital content and issues to itself a corresponding digital publisher license to allow itself to render the published digital content. The publishing user is supplied with a publishing certificate from a digital rights management (DRM) server, where the publishing certificate allows the publishing user to so publish the digital content and to so issue the publisher license.
