Google Patent Search

ArnoldIT.com made available the Google patent documents from 1998 through 2008. ISYS Search Software indexed this corpus and created a publically accesible search system with three features not previously available without charge.

• Advanced refinement and mining options such as entity extraction and parametric search
• A corpus consisting of XHTML versions of the USPTO Google patent documents
• Hot links to the PDF image file of the patent document

You can run queries against this corpus and compare results with those available from the USPTO search system, Google's patent search, and other services such as FreePatentsOnline.com, among others.
