Abstract

An intelligent agent capable of traversing sites in a computer network to identify intellectual property (IP) infringement issues that may exist in those network sites and a method of identifying such IP infringement issues. In one embodiment, the agent includes: (1) a site database containing sites to be traversed, (2) an IP database containing IP indicia to be compared and (3) a site examiner, associated with the site and IP databases, that traverses the sites identified in the site database, compares data associated with the sites with the IP indicia in the IP database and creates a record of favorable comparisons between the data and the IP indicia.

Claims

1. A method of identifying intellectual property (IP) infringement issues associated with sites of a computer network, comprising:

creating a site database containing sites to be traversed;

creating an IP database containing IP indicia to be compared, said IP indicia being selected from the group consisting of patent keywords, filenames, wordmarks, watermark-free logo images, and copyrighted textual passages;

traversing said sites identified in said site database;

comparing data associated with said sites with said IP indicia in said IP database; and

creating a record of favorable comparisons between said data and said IP indicia.

2. The method as recited in claim 1 wherein said sites are selected from the group consisting of:

World Wide Web sites,

Internet Relay Chat (IRC) channels,

Usenet newsgroups,

Wide Area Information Systems (WAIS),

Gopher servers, and

File Transfer Protocol (FTP) servers.

3. The method as recited in claim 1 wherein said site database contains an examination depth indicator associated with each of said sites, said step of traversing comprising the step of traversing said sites identified in said site database to an extent based on said examination depth indicator.

4. The method as recited in claim 1 wherein said site database contains geographic site demarcations.

5. The method as recited in claim 1 wherein said step of comparing comprises the step of correlating said data and said IP indicia.

6. The method as recited in claim 1 further comprising the step of creating a favorable comparison database that contains said record and other records created during traversal of said sites.

8. The agent as recited in claim 1 wherein said sites are selected from the group consisting of:

World Wide Web sites,

Internet Relay Chat (IRC) channels,

Usenet newsgroups,

Wide Area Information Systems (WAIS),

Gopher servers, and

File Transfer Protocol (FTP) servers.

9. The agent as recited in claim 1 wherein said site database contains an examination depth indicator associated with each of said sites, said site examiner traversing said sites identified in said site database to an extent based on said examination depth indicator.

10. The agent as recited in claim 1 wherein said site database contains geographic site demarcations.

11. The agent as recited in claim 1 wherein said favorable comparisons are based on correlations between said data and said IP indicia.

12. The agent as recited in claim 1 further comprising a favorable comparison database that contains said record and other records that said site examiner creates during traversal of said sites.

7. For use in traversing sites of a computer network to identify intellectual property (IP) infringement issues associated therewith, an agent, comprising:

a site database containing sites to be traversed;

an IP database containing IP indicia to be compared, said IP indicia being selected from the group consisting of patent keywords, filenames, wordmarks, watermark-free logo images, and copyrighted textual passages; and

a site examiner, associated with said site and IP databases, that traverses said sites identified in said site database, compares data associated with said sites with said IP indicia in said IP database and creates a record of favorable comparisons between said data and said IP indicia.

13. For use in traversing Internet sites to identify intellectual property (IP) infringement issues associated therewith, an agent, comprising:

a site database containing sites to be traversed and an examination depth indicator associated with each of said sites;

an IP database containing IP indicia to be compared, said IP indicia being selected from the group consisting of patent keywords, filenames, wordmarks, watermark-free logo images, and copyrighted textual passages;

a site examiner, associated with said site and IP databases, that traverses said sites identified in said site database to an extent based on said examination depth indicator and compares data associated with said sites with said IP indicia in said IP database; and

a favorable comparison database that contains records of favorable comparisons that said site examiner creates during traversal of said sites.

14. The agent as recited in claim 13 wherein said sites are selected from the group consisting of:

World Wide Web sites,

Internet Relay Chat (IRC) channels,

Usenet newsgroups,

Wide Area Information Systems (WAIS),

Gopher servers, and

File Transfer Protocol (FTP) servers.

15. The agent as recited in claim 13 wherein said site database contains geographic site demarcations.

16. The agent as recited in claim 13 wherein said favorable comparisons are based on correlations between said data and said IP indicia.

17. The agent as recited in claim 13 wherein said sites are obtained from a Uniform Resource Locator (URL) database associated with a search engine.
