SYSTEM AND METHOD FOR PATENT AND PRIOR ART ANALYSIS

Systems and techniques for analyzing patents and prior art in a patent management system are described herein. Claims of an issued and a published patent may be retrieved. The claims may be compared to identify a unique keyword present in the issued claim but not present in the published claim. The unique keyword may be cross-referenced to a passage in a specification of the issued patent. A first and second prior art document may be identified. Overlap scores may be calculated for the first and second prior art document based on the occurrence of the unique keyword. A ranking may be calculated based on a comparison of the overlap scores. The overlap score of the first prior art document, the overlap score of the second prior art document based on the ranking and the passage in the specification of the issued patent may be displayed in a user interface.
