Abstract

A method and system for searching patent-related documents includes selecting a portion of a selected claim of a patent and selecting a portion of a disclosure of the patent. The method further includes comparing the claim portion with the disclosure portion. Based on the comparison, claim interpretation data may be determined that is associated with the portion of the claim. The method may also include searching a database for patent-related documents relevant to the selected claim based on the claim interpretation data.

Claims

1. A method for searching patent-related documents performed by a computer system, comprising:

selecting a portion of a selected claim of a patent;

selecting a portion of a disclosure of the patent;

comparing the claim portion with the disclosure portion;

determining claim interpretation data associated with the portion of the claim based on the comparison; and

searching a database for patent-related documents relevant to the selected claim based on the claim interpretation data.

2. The method of claim 1, wherein selecting the portion of the disclosure includes:

selecting at least a portion of a dependent claim of the selected claim of the patent.

3. The method of claim 1, wherein selecting the portion of the disclosure includes:

selecting at least a portion of at least one of a specification of the patent and text associated with one or more figures of the patent.

4. The method of claim 1, wherein determining the claim interpretation data includes:

generating a modified version of the portion of the claim based on the comparison that reflects a meaning of the portion of the claim in the context of the disclosure portion.

5. The method of claim 1, wherein comparing the claim portion with the disclosure portion includes:

identifying text within the disclosure portion that corresponds to the claim portion.

8. The method of claim 1, wherein comparing the claim portion with the disclosure portion includes:

identifying text within the disclosure portion that corresponds to a first claim term within the claim portion; and

generating a list for the first claim term including the identified text.

9. The method of claim 8, wherein determining the claim interpretation data further includes:

adding the text from the list to the claim portion to generate a modified claim portion, wherein the text is added to a location where the first claim term is present within the claim portion.

10. The method of claim 1, wherein determining the claim interpretation data includes:

adding the claim interpretation data to a claim interpretation database that stores claim interpretation data from other searches for patent-related documents.

11. The method of claim 10, wherein searching further includes:

searching the claim interpretation database for patent-related documents based on a search query formed from the claim interpretation data.

12. The method of claim 11, wherein searching further includes:

identifying a term within the claim interpretation data stored in the claim interpretation database that corresponds to the search query; and

identifying a patent-related document corresponding to the identified term within the claim interpretation data.

13. The method of claim 1, wherein selecting a portion of the selected claim includes:

selecting the portion of the selected claim based on selection criteria.

14. The method of claim 13, wherein the selection criteria is based on a structure of the selected claim.

6. The method of claim 6, wherein determining the claim interpretation data includes:

inserting the identified text in the claim portion to create a modified claim portion.

7. The method of claim 6, wherein searching includes:

generating a search query based on terms included in the modified claim portion; and

searching the database using the search query.

15. A system for searching patent-related documents, comprising:

a computer system configured to;

select a portion of a selected claim of a patent;

select a portion of a disclosure of the patent;

compare the claim portion with the disclosure portion;

determine claim interpretation data associated with the portion of the claim based on the comparison, and

database system including patent-related documents,

wherein the computer system is further configured to send a search command to the database system to search for patent-related documents relevant to the selected claim portion based on the claim interpretation data.

16. The system of claim 15, wherein the computer system is configured to select at least a portion of a dependent claim of the selected claim of the patent as the selected claim portion.

17. The system of claim 15, wherein the computer system is configured to select at least a portion of at least one of a specification of the patent and text associated with one or more figures of the patent as the selected disclosure portion.

18. The system of claim 15, wherein the computer system is configure to generate a modified version of the portion of the selected claim based on the comparison that reflects a meaning of the portion of the selected claim in the context of the disclosure portion.

19. The system of claim 15, wherein the computer system is configured to identify text within the disclosure portion that corresponds to the claim portion.

20. The system of claim 19, wherein the computer system is configured to insert the identified text in the claim portion to create a modified claim portion.

21. The system of claim 20, wherein the computer system is configured to generate a search query based on terms included in the modified claim portion and generate the search command based on the search query.

22. The system of claim 15, wherein the computer system is configured to identify text within the disclosure portion that corresponds to a first claim term within the claim portion and generate a list for the first claim term including the identified text.

23. The system of claim 22, wherein the computer system is configured to add the text from the list to the claim portion to generate a modified claim portion, wherein the text is added to a location where the first claim term is present within the claim portion.

24. The system of claim 15, wherein the computer system is configured to add the claim interpretation data to a claim interpretation database that stores claim interpretation data from other searches for patent-related documents.

25. The system of claim 24, wherein the computer system is configured to search the claim interpretation database for patent-related documents based on a search query formed from the claim interpretation data.

26. A method for searching patent-related documents associated with a selected claim term within a patent, the method performed automatically by a computer system executing software comprising:

determining a context of the selected claim term in relation to a disclosure of the patent;

generating a search query based on the determined context of the selected claim term; and

searching a database to identify one or more of the patent-related documents that are relevant to the search query.

27. A computer-readable medium including instructions that, when executed by a processor, perform a method for searching patent-related documents associated with a selected claim term within a patent, the method comprising:

determining a context of the selected claim term in relation to a disclosure of the patent;

generating a search query based on the determined context of the selected claim term; and

searching a database to identify one or more of the patent-related documents that are relevant to the search query.
