摘要：This article shows a current software patent case where the MPEG Licensing Administration (MPEG-LA) is claiming license fees for the implementation of the (open) rights expression language ODRL. ODRL has been developed by the international ODRL Initiative, a non-profit initiative mainly run by researchers. The article critically discusses the patents for rights expression languages and introduces early publications, showing that the concept of ¡°rights expression languages or a rights grammar¡± is not new. Furthermore, it examines the patent claims with regard to the Open Mobile Alliance (OMA) DRM. The article is concluded with a discussion on the potential future impact of software patents in the field of DRM for open source software, research and consumers.
