Abstract
A method to delivery encrypted digital content to a end user system for playing the content comprising the steps of: reading from a computer readable medium metadata which has previously associated with the content. A user selects from the metadata associated content to decrypt and the end user system establishes a secure connection with an authorization authority for decrypting the content. The end user system receives a secure container containing the decrypting key for decrypting at least part of the previously encrypted content as permitted. The system creates a secure container using the encrypting key from a clearing house, wherein the secure container has an encrypting key therein from the end user system; transferring the secure container to the clearing house for authentication of permission to decrypt the content. The system receives from the clearing house, a secure container encrypted using the encrypting key of the end user system containing the decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted; and playing at least part of the previously encrypted content by decrypting the secure container using the encrypting key of the end user system to access the decrypting key for decrypting at least part of the encrypted content.

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.
