Abstract
Embodiments of the present invention overcome the problems in the existing art described above by providing a secure digital content licensing system and method. Rental of the digital content occurs within an online environment including one or more user network-enabled devices and one or more server network devices connected by a communications link to the one or more user network-enabled devices. A user selects content displayed on a main website and requests download of the selected content to the user network-enabled device. To be able to access the content the user must obtain a license. The user's request for a license for specific content comprises information about a desired rental model, an expiration date for the rental model, and information that identifies the user's user network-enabled device, along with other information. A license for the content is generated which comprises the above information and also includes an encryption key for the selected movie. Media player and security technology residing on the user network-enabled device provides protection against unauthorized access to the content by ensuring that only licensed content is viewed and is accessed according to the rental model contained in the license. Media player and security technology also provides security against tampering by performing integrity checks on its various components and other components within the user network-enabled device. Revocation of access rights is made possible by revocation certificates that inhibit accessing of particular content for various reasons including compromised files or components.

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.
