Abstract

An enforceable property right and a system for controlling the manner of use of an item in accordance with usage rights. The enforceable property right includes an item ticket having a security mechanism incorporated therein and specifying an item for which the item ticket can be redeemed and a license associated with the item ticket. The license includes usage rights specifying a manner of use for redeeming the item ticket and a mechanism for unlocking said security mechanism.

Claims

1. A method for enforcing a property right within a system for controlling a manner of use of an item in accordance with usage rights, the method comprising:

obtaining an enforceable property right for a specific item, including obtaining an electronic item ticket specifying the specific item as an item for which the electronic item ticket is redeemed, the electronic item ticket having a security mechanism incorporated therein, and

obtaining a digital license associated with the electronic item ticket, the digital license including usage rights specifying a manner of use for redeeming the electronic item ticket and conditions for exercising the manner of use;

electronically parsing the digital license for usage rights and conditions;

determining if the conditions are satisfied;

if the conditions are satisfied, rendering or accessing the electronic item ticket through the digital license by unlocking the security mechanism of the electronic item ticket, and if the conditions are not satisfied, not allowing rendering or accessing of the electronic item ticket; and

controlling the manner of use of the specific item by controlling the manner of use for redeeming the electronic item ticket in accordance with the determined usage rights,

wherein the digital license includes post-license conditions that do not need to be satisfied for unlocking the security mechanism, and

the method further comprises permitting a specification of the item and the post-license conditions to be rendered or accessed,

wherein the digital license includes state variables.

2. The method as recited in claim 1, wherein the electronic item ticket includes a description of the item.

3. The method as recited in claim 1, wherein the electronic item ticket includes an ID correlated to the item.

4. The method as recited in claim 1, wherein the electronic item ticket includes limitations specified by the digital license.

5. The method as recited in claim 4, wherein the limitations are expressed as conditions.

6. The method as recited in claim 7, wherein the security mechanism is encryption and the unlocking step comprises executing a decryption algorithm.

7. The method as recited in claim 1, wherein the item includes goods.

8. The method as recited in claim 1, wherein the item includes services.

9. The method as recited in claim 1, wherein the digital license includes a specification of a corresponding electronic item ticket.

10. The method as recited in claim 1, wherein the item is information.

11. The method as recited in claim 10, wherein the digital license further comprises usage rights specifying access to the information and conditions of the access.

12. The method as recited in claim 11, wherein the conditions include a security or trust rating, and the determining step comprises determining if a users rating corresponds to the trust rating.

13. The method as recited in claim 7, wherein the item is an online service.

14. The method as recited in claim 13, wherein the digital license further comprises usage rights specifying access to the online service and conditions of the access.

15. The method as recited in claim 14, wherein the conditions include a security or trust rating, and the determining step comprises determining if a user'"'"'s rating corresponds to the trust rating.

16. The method as recited in claim 1, wherein the usage rights include meta-rights which permit rights in the item to be granted to downstream parties and further comprising the steps of deriving rights form the meta-rights and generating a digital license including the derived rights.

17. The method as recited in claim 1, wherein the item is a financial instrument.

18. The method as recited in claim 1, wherein the item is a legal document.

19. The method as recited in claim 1, wherein the item is real estate.

20. The method as recited in claim 1, wherein the item is a tangible item comprising tangible goods or services, including a printed book, music on a physical media, an airline ticket, a car rental, or an event.

21. The method as recited in claim 1, wherein the item is an intangible item, comprising intangible goods or services, including an electronic book, or electronic music.

22. A system for enforcing property rights in items by controlling use of the items in accordance with usage rights, the system comprising:

a license device operative to associate a digital license with an electronic item ticket, the electronic item ticket specifying an item for which the electronic item ticket is redeemed and having a security mechanism incorporated therein, the digital license including usage rights specifying a manner of use for redeeming the electronic item ticket and conditions for exercising the manner of use; and

a client environment operative to obtain the electronic item ticket and the digital license and to control the manner of use of the item by including a security component operative to determine usage rights and conditions from the digital license, unlock the security mechanism of the electronic item ticket when the conditions are satisfied and not unlock the security mechanism of the electronic item ticket when the conditions are not satisfied, and enforce the usage rights of the digital license for the item for which the electronic item ticket is redeemed,

wherein the digital license further includes condition that must be satisfied to activate the unlocking of the security mechanism.

the digital license includes post-license conditions that do not need to be satisfied for unlocking of the security mechanism.

the security component permits a specification of the item and the post-license conditions to be rendered or accessed, and

the digital license includes state variables.

23. The system as recited in claim 22, further comprising an activation device for providing at least a portion of the security component of the client environment, wherein the security component is included in a user device.

24. The system as recited in claim 23, further comprising a vendor device for permitting a user to select an item and usage rights to be incorporated into the digital license generated by the license device.

25. The system as recited in claim 22, wherein the item is a tangible item comprising tangible goods or services, including a printed book, music on a physical media, an airline ticket, a car rental, or an event.

26. The system as recited in claim 22, wherein the item is an intangible item, comprising intangible goods or services, including an electronic book, or electronic music.

27. A computer readable medium including one or more computer readable instructions embedded therein for enforcing an enforceable property right for use within the system for controlling the manner of use of an item in accordance with usage rights, and configured to cause one or more processors to perform the steps of:

specifying via an electronic item ticket a specific item as an item for which the electronic item ticket is redeemed, the electronic item ticket having a security mechanism incorporated therein; and

associating a digital license with the electronic item ticket, the digital license including usage rights specifying a manner of use for redeeming the electronic item ticket and means for unlocking the security mechanism, whereby the electronic item ticket is rendered or accessed through the unlocking means of the digital license, if the conditions are satisfied, and whereby the electronic item ticket is not allowed to be rendered or accessed, if the conditions are not satisfied,

wherein the manner of use of the specific item is controlled by controlling the manner of use for redeeming the electronic item ticket in accordance with the determined usage rights,

wherein the digital license further includes condition that must be satisfied to activate the means for unlocking.

the digital license includes post-license conditions that do not need to be satisfied to activate the security mechanism.

the unlocking mechanism permits a specification of the item and the post-license conditions to be rendered or accessed, and
