Abstract

Disclosed are a method, machine-readable code, and a database for use in identifying, among a group of patent practitioners, one or more practitioners having expertise related to a given invention or technology. In the method, a search query related to the given invention or technology is used to identify one or more texts of patent abstracts or claims or patent class definitions having high term matches with the user-input query. The identified text(s) are linked to patent-class tags associated with the texts, and the identified tags are linked to one or more members of a group of patent practitioners who wrote and/or prosecuted patents having the patent-class assignments.

Claims

1. A computer-assisted method for identifying, from among a group of patent practitioners in a given locale, one or more practitioners having technical expertise related to a given invention or technology area, comprising

(a) processing a user-input query composed of word, and optionally, word-group terms that describe or are descriptive of the given invention or technology area,

(b) accessing a database containing a word index of texts of patent abstracts or patent claims or patent classification definitions, to identify one or more texts having high term matches with the user-input query,

(c) accessing a database containing texts linked to patent-class tags linked to the texts, to identify one or more one or more patent-class tags linked to the texts identified in step (b),

(d) accessing a database containing patent-class tags linked to the names and locales of patent practitioners who have prepared patents to which such patent-class tags have been assigned, to identify one or more patent practitioners in a given locale associated with the patent-class tags identified in step (c) and

(e) presenting the patent practitioners identified in step (d) to the user.

2. The method of claim 1, wherein said processing in step (a) includes constructing a search vector composed of non-generic words, and optionally, word-group terms, and term-value coefficients assigned to each term, and said accessing step (b) is effective to identify texts having the top match score with the search vector.

3. The method of claim 1, wherein the databases accessed in each of steps (b)-(d) are database tables in a relational database.

4. The method of claim 1, wherein the database accessed in step (b) includes a word index of abstracts from patents, and the database accessed in step (c) includes a text-ID table linking the abstracts to patent-class number tags associated with patents from which the abstracts are taken.

5. The method of claim 1, wherein the database accessed in step (b) includes a word index of patent-class definitions, and the database accessed in step (c) includes a text-ID table linking the patent-class definitions to associated patent-class number tags.

6. The method of claim 1, wherein said database accessed in step (c) includes a matrix whose matrix values represent, for each pair of patent-class tags, a co-occurrence value related to the document co-occurrence of the two tags of the pair in the patents from which the tags were taken, and step (c) includes accessing the database to identify one or more one or more tags linked directly to the text(s) identified in step (b), or linked indirectly to the text(s) identified in (b) through an above-threshold co-occurrence value to a tag directly linked to such text(s).

7. The method of claim 6, wherein the user can adjust the co-occurrence value applied by the method in step (d).

8. The method of claim 1, wherein said database accessed in step (d) includes a locale database in which specified locales are zip codes or counties that are linked to proximate zip codes or counties, and step (d) includes accessing the database to identify one or more patent practitioners linked to a specified locale or linked to locale that is proximate to the specific locale.

9. The method of claim 6, wherein the user can adjust the degree of locale proximity applied by the method in step (d).

10. The method of claim 1, wherein said step (e) includes presenting, with each patent practitioners identified in step (d), a link to that patent practitioner'"'"'s website.

11. For use in identifying, among a group of patent practitioners in a given loocale, one or more practitioners having technical expertise related to a given invention or technology, machine-readable code which is operable on a computer to execute machine-readable instructions for performing the steps comprising

(a) processing a user-input query composed of word, and optionally, word-group terms that are descriptive of the given invention,

(b) accessing a database containing a word index of texts of patent abstracts or patent claims or patent classification definitions, to identify one or more texts having high term matches with the user-input query,

(c) accessing a database containing patent-class tags linked to the texts, to identify one or more one or more patent-class tags linked to the texts identified in step (b),

(d) accessing a database containing the names and locales of patent practitioners linked to patent-class tags that have been assigned to patents prepared by such patent practitioners, to identify one or more patent practitioners in a given locale associated with the patent-class tags identified in step (c) and

(e) presenting the patent practitioners identified in step (d) to the user.

12. The machine-readable code of claim 11, wherein the databases accessed are part of a single relational database.

13. A relational database for use in identifying, among a group of patent practitioners, one or more practitioners having expertise related to a given invention or technology, comprising database tables containing:

(i) a word index of texts of patent abstracts or claims or patent-class definitions taken from a library of patents or from a dictionary of patent classes, respectively,

(ii) citation tags linked to the texts, where the tags represent patent-class tags assigned to said texts, and

(iii) group-member identifiers linked to patent-class tags, through patent-class tags taken from patents prepared by members of the group of practitioners.

14. The database of claim 13, which includes a matrix whose matrix values represent, for each pair of patent-class tags, a co-occurrence value related to the document co-occurrence of the two tags of the pair in the patents from which the tags were taken.
