ContentGuard Awarded Five New Digital Rights Management Patents
Inventions Improve Protected Distribution of Enterprise Content and Composite Digital Works
BETHESDA, MD -- 12/20/2004 -- ContentGuard, Inc., a leading holder of Digital Rights Management (DRM) intellectual property, announced today that it has added five new DRM patents; one by the US Patent and Trademark Office, three by the European Patent Office and one by the Japanese Patent Office, to its broad patent portfolio.
The U.S. patent 6,824,051 describes a rights management system for managing the use of items by authorized users who are part of an access list.
The three patents issued by the European Patent Office, EP 1 335 260 B1, EP 1 335 261 B1, and EP 1 335 262 B1, cover the control of access to content with more than one part. Tailored usage rights may be created for different parts of the content and a user is permitted to access the respective parts of the content only in accordance with those usage rights. Patent 3610350 issued by the Japanese Patent Office concerns managing digital content within a transportable storage device in accordance with assigned usage rights.
“Authorized access lists are used in many types of digital distribution in the enterprise, as well as for content subscriptions,” said Michael Miron, CEO of ContentGuard. “With content distributors increasingly tailoring access rights according to content type, or even the specific chapter or song within this content, our new patents meet an emerging and important need. This provides further validation of ContentGuard’s pioneering work in creating DRM inventions that can be used globally by content distributors, device manufacturers and consumers to create new business models and expand the digital content market.”
ContentGuard intends to add these patents to its growing worldwide portfolio of more than 30 patents available for licensing by interested parties.
