On Tuesdays the USPTO publishes new patents. Both of today's Spotlight Patents address aspects of DRM. Assigned to LG Electronics, the first patent concerns techniques for processing digital rights management contents containing advertising contents. Assigned to Microsoft, the second patent concerns techniques for software application protection by way of a digital rights management.
7,681,243, "Method and apparatus for processing digital rights management contents containing advertising contents," assigned to LG Electronics (KR).
Abstract
A method and apparatus for processing digital rights managements (DRM) contents having advertisement (AD) contents attached thereto in a DRM system are disclosed. When DRM contents including AD contents are selected by a DRM device, a rights issuer (RI) receives the AD contents and the DRM contents from a contents issuer (CI), generates a multipart contents format file, and downloads it to the DRM device. Then, the DRM device decodes the downloaded multipart contents format file to check whether the multipart contents format file includes AD contents-attached DRM contents, and if so, the DRM device reproduces the AD contents to use the DRM contents free of cost. Thus, the DRM contents can be provided to a user by using the AD contents without causing a burden of a charge.
7,680,743, "Software application protection by way of a digital rights management (DRM) system," assigned to Microsoft.
Abstract
A digital rights management (DRM) system, an application, and a DRM digital license for the application are all on a computing device. The application is for being executed to perform a function and includes code requiring that the DRM system determine that the application is allowed to be executed to perform the function based on the license. The application further includes code for determining that the application is to be executed on one of the computing device or in connection with the DRM system.
