Abstract

A rights management system including one or more consequential rights associated with digital content, and specifying a manner of use of the digital content, a right management module that enforces the rights permitting use of the digital content in accordance with the rights upon occurrence of a consequential event. The consequential event is based on another usage right. In one embodiment, the consequential event is the exercise, expiration, or possession of another usage right.

Claims

1. A rights management system for managing and enforcing rights to digital works comprising:

at least one repository for enforcing rights associated with digital content;

a usage right associated with a first digital content, said usage right specifying manner of use of the first digital content;

a consequential right associated with a second digital content, said consequential right specifying a manner of use of the second digital content and a consequential event such that the consequential right is exercisable only after occurrence of the consequential event; and

a rights management module that enforces the consequential rights by permitting use of the second digital content in accordance with the specified manner of use only upon occurrence of the consequential event;

wherein said consequential event is at least one of exercise and expiration of the usage right to thereby provide sequential access to said first digital content and said second digital content.

2. The system of claim 1, wherein the manner of use includes at least one of, editing, approving, modifying, executing, updating and copying.

3. The system of claim 1, wherein the manner of use is manner of rendering the first or second digital content.

4. The system of claim 1, wherein the first or second digital content comprises at least one of, books, audio information, music, multimedia presentations, executable code, and video information.

5. The system of claim 1, wherein said consequential event is the exercise of the usage right.

6. The system of claim 1, wherein said consequential event is the expiration of the usage right.

7. The system of claim 1, wherein said consequential event is based on a plurality of events, at least one of said plurality of events being at least one of exercise and expiration of the usage right.

8. The system of claim 7, wherein said consequential event is determined to have occurred upon occurrence of all of said plurality of events.

9. The system of claim 7, wherein said consequential event is determined to have occurred upon occurrence of any of said plurality of events.

10. The system of claim 7, wherein said consequential event is determined to have occurred upon sequential occurrence of said plurality of events.

11. The system of claim 1, wherein said first or second digital content comprises an educational course.

12. The system of claim 1, wherein said first or second digital content comprises an examination.

13. A method of managing and enforcing rights to use digital works in a system having at least one repository for enforcing rights associated with content of the digital works, the method comprising the steps of:

electronically determining a usage right associated with a first digital content, said usage right specifying manner of use of the first digital content;

electronically determining a consequential right associated with a second digital content, said consequential right specifying a manner of use of the second digital content and a consequential event, and being exercisable only upon occurrence of said consequential event; and

enforcing said consequential right to permit use of said second digital content in accordance with the manner of use specified only upon occurrence of the consequential event;

wherein said consequential event is at least one of exercise and expiration of the usage right to thereby provide sequential access to said first digital content and said second digital content.

14. The method of claim 13, wherein the manner of use includes at least one of viewing, printing, editing, approving, modifying, updating and copying.

15. The method of claim 13, wherein the manner of use is a manner of rendering the first or second digital content.

16. The method of claim 13, wherein the first or second digital content comprises at least one of books, audio information, music, multimedia presentations, executable code, and video information.

17. The method of claim 13, wherein said consequential event is the exercise of the usage right.

18. The method of claim 13, wherein said consequential event is the expiration of the usage right.

19. The method of claim 13, wherein said consequential event is based on a plurality of events.

20. The method of claim 19, wherein said consequential event is determined to have occurred upon occurrence of all of said plurality of events.

21. The method of claim 19, wherein said consequential event is determined to have occurred upon occurrence of any of said plurality of events.

22. The method of claim 19, wherein said consequential event is determined to have occurred upon sequential occurrence of said plurality of events.

23. A computer readable media, including one or more computer-readable instructions, for managing and enforcing rights to digital works in a system having at least one repository for enforcing rights associated with content of the digital works, the computer-readable instructions configured to cause one or more computer processors to perform the steps of:

determining a usage right that specifies a manner of use of a first digital content; and

determining a consequential right associated with a second digital content, said consequential right specifying manner of use of the second digital content and consequential event that must occur to exercise said consequential right;

wherein the consequential event is at least one of exercise and expiration of the usage right to thereby provide sequential access to said first digital content and said second digital content.

24. The computer readable media of claim 23, wherein the manner of use includes at least one of editing, approving, modifying, updating and copying.

25. The computer readable media of claim 23, wherein the manner of use is a manner of rendering.

26. The computer readable media of claim 23, wherein the digital works comprise at least one of books, music, audio information, multimedia presentations, executable code and video information.

27. The computer readable media of claim 23, wherein said consequential event is the exercise of the usage right.

28. The computer readable media of claim 23, wherein said consequential event is the expiration of the usage right.

29. The computer readable media of claim 23, wherein said consequential event is based on a plurality of events.

30. The computer readable media of claim 29, wherein said consequential event is determined to have occurred upon occurrence of all of said plurality of events.

31. The computer readable media of claim 29, wherein said consequential event is determined to have occurred upon occurrence of any of said plurality of events.

32. The computer readable media of claim 29, wherein said consequential event is determined to have occurred upon sequential occurrence of said plurality of events.
