Abstract
The present invention relates to digital rights management. In one embodiment, persons, processes, and/or computers and appliances locate, share, publish, retrieve, and use all kinds of digital information that has been protected using digital rights management technologies. Rights management includes securely associating rules for authorized use with the digital information. Rules and/or digital information may be encapsulated in a cryptographically secure data structure or 'container' ('CSC') to protect against unauthorized use, to ensure secrecy, to maintain integrity, and to force the use of a rights management system to access the protected information. Attributes or metadata information describing at least some of the rules ('rules-metadata information') and optionally any associated rule parameter data with respect to the protected information are created. This rules-metadata information may be organized, structure, encoded, and/or presented using a self-defining data structure such as those created using Extensible Markup Language (XML). In one embodiment, the XML-encoded rules-metadata information is also made available unencrypted, in plain text, to facilitate P2P search and file transfer. Having at least some of the rules-metadata information outside or external to a CSC allows greater flexibility in searching based at least in part upon the rules-metadata information. Some embodiments may hold the rules-metadata information in a separate CSC. Putting the rules-metadata information in a separate CSC more easily allows authentication and maintains the integrity of the rules-metadata information. In another embodiment, the rules metadata may be in an unencrypted portion of a CSC itself or concatenated with a CSC in a single file.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
