System and method for patent and prior art analysis

Systems and techniques for patent and prior art analysis are described herein. An issued independent claim of the identified patent is electronically retrieved. A pre-allowance published independent claim of the identified patent is electronically retrieved. The issued independent claim is automatically compared to the pre-allowance published independent claim using at least one unique keyword. A search query string is formulated comprising the at least one unique keyword. A search query is executed to a prior art database comprising a set of prior art documents using the search query string to identify a result prior art document set. An owner of each prior art document of the result prior art document set is identified. The owner is automatically ranked based on a number of keywords from the search query string owned by the owner. A user interface is output to a user comprising a visualization of the rank of the owner.
