6 . The method as claimed in claim 1 , further comprising altering the size of the first circle and/or the second circle based on one or more user-defined filter terms, wherein the one or more user-defined filter terms filter electronic documents of the first document set and/or the second document set.

7 . The method as claimed in claim 1 , further comprising:

identifying electronic documents in the first document set and the second document set that satisfy at least one user-defined parameter; and

populating the first circle and the second circle with a plurality of graphical representations of electronic documents satisfying the at least one user-defined parameter, wherein a first portion of the plurality of graphical representations of electronic documents is located within the first circle near a second portion of the plurality of graphical representations of electronic documents located within the second circle.

8 . The method as claimed in claim 1 , further comprising:

determining one or more semantically similar terms of electronic documents within the overlap region;

generating one or more additional search queries based on the one or more semantically similar terms;

searching the electronic document database using the one or more additional search queries to obtain one or more additional document sets; and

displaying one or more visual representations of one or more search result sets using the one or more additional search queries.

9 . A method of graphically representing electronic document searches, the method comprising:

receiving at least a first search query and a second search query;

searching an electronic document database using the first search query and the second search query to obtain a first document set based on the first search query and a second document set based on the second search query, wherein the first document set comprises a first plurality of electronic documents and the second document set comprises a second plurality of electronic documents;

identifying electronic documents in the first document set and the second document set that satisfy at least one user-defined parameter;

generating a Venn diagram for display on a graphic display device, the Venn diagram comprising a first circle that represents the first document set and a second circle that represents the second document set, wherein:

a size of the first circle and the second circle reflect a number of electronic documents in the first document set and in the second document set, respectively; and

the first circle overlaps the second circle in an overlap region, the overlap region depicting common electronic documents that are within the first document set and the second document set; and

populating the first circle and the second circle with a plurality of graphical representations of electronic documents satisfying the at least one user-defined parameter, wherein a first portion of the plurality of graphical representations of electronic documents is located within the first circle near a second portion of the plurality of graphical representations of electronic documents located within the second circle.

10 . The method as claimed in claim 9 , wherein the first and second plurality of electronic documents are patent documents, and the type of structured data field comprises one or more of the following: inventor name, class, subclass, authority, title, claims, assignee, and filing date.

11 . The method as claimed in claim 9 , further comprising, in response to a user selecting a selected portion of the first circle, the second circle, and/or the overlap region corresponding to at least a portion of the plurality of graphical representations, listing electronic documents that are included within the selected portion.

12 . The method as claimed in claim 9 , further comprising, in response to a user selecting a selected portion of the first circle, the second circle, and/or the overlap region corresponding to at least a portion of the plurality of graphical representations of electronic documents, depicting a second Venn diagram including the selected portion of the Venn diagram.

13 . The method as claimed in claim 9 , further comprising, in response to a user input, generating a visualization chart of electronic documents within the first circle, the second circle, or the overlap region, wherein the visualization chart of electronic documents represents the electronic documents sorted by one or more structured data fields.

14 . A method of electronic document searching, the method comprising:

receiving at least a first search query and a second search query;

searching an electronic document database using the first search query and the second search query to obtain a first document set based on the first search query and a second document set based on the second search query, wherein the first document set comprises a first plurality of electronic documents and the second document set comprises a second plurality of electronic documents;

generating a Venn diagram for display on a graphic display device, the Venn diagram comprising a first circle that represents the first document set and a second circle that represents the second document set, wherein:

a size of the first circle and the second circle reflect a number of electronic documents in the first document set and in the second document set, respectively; and

the first circle overlaps the second circle in an overlap region, the overlap region depicting common electronic documents that are within the first document set and the second document set;

determining one or more semantically similar terms of electronic documents within the overlap region;

generating one or more additional search queries based on the one or more semantically similar terms;

searching the electronic document database using the one or more additional search queries to obtain one or more additional document sets; and

displaying one or more visual representations of one or more search result sets using the one or more additional search queries.

15 . The method as claimed in claim 14 , wherein the one or more visual representations indicate a number of electronic documents within the one or more search result sets.

16 . The method as claimed in claim 14 , wherein user selection of the one or more visual representations generates a preview of electronic documents within the selected visual representation of electronic documents.

17 . The method as claimed in claim 14 , wherein one or more electronic documents within the one or more additional document sets are not contained in the first document set and the second document set.

18 . The method as claimed in claim 14 , wherein determining one or more semantically similar terms comprises identifying one or more common terms within electronic documents contained in the overlap region, generating semantic terms that are semantically similar to the one or more common terms, and identifying common semantic terms within the electronic documents contained in the overlap region.

19 . The method as claimed in claim 14 , further comprising, in response to a user input, generating a visualization chart of electronic documents within the first circle, the second circle, or the overlap region, wherein the visualization chart of electronic documents represents the electronic documents sorted by one or more structured data fields.
