The US Patent Office issues new patents on Tuesdays. Issued patents and published applications may be early indicators of the kinds of issues being addressed by inventors and/or the companies for whom they work. Assigned to Phocis Limited, today's patent deals generally with rights management.
7,210,039, Digital rights management, assigned to Phocis Limited.
The present invention relates to digital rights management and more particularly to a system and method for securely publishing and controlling the usage of digital content. Advantageously a publisher or owner of digital content or of a copyright work can distribute securely that work in a secure digital form.
This patent appears to be a great example of how to get something issued in the United States by not citing relevant art to the patent examiner. Maybe other art was cited but not listed in the issued patent. Nonetheless, for an application filed in 2001 with a 2000 priority date, lots seems to be missing:
