8. At least one non-transitory computer-readable medium including instructions stored thereon, which when executed by at least one processor, configure the at least one processor to: retrieve, from at least one database, at least one independent claim of the patent as issued; retrieve, from the at least one database, at least one independent claim of the corresponding patent application as published; automatically compare the at least one issued independent claim to the at least one published independent claim by identifying at least one unique keyword present in the issued independent claim but not present in the published independent claim; cross-reference the at least one identified unique keyword to a passage in the specification of the issued patent, wherein the at least one identified unique keyword is cross-referenced to the passage in the specification of the issued patent using input received from a user interface; identify a first prior art document and a second prior art document; calculate an overlap score for the first prior art document based on at least one occurrence of the at least one unique key word in the first prior art document; calculate an overlap score for the second prior art document based on at least one occurrence of the at least one unique keyword in the second prior art document; calculate a ranking for the first prior art document by comparing the calculated overlap score of the first prior art document to the calculated overlap score of the second prior art document; and display, in the user interface, a graphical representation of the calculated overlap score of the first prior art document and a graphical representation of the calculated overlap score of the second prior art document based on the ranking, and the passage in the specification of the issued patent.
8. At least one non-transitory computer-readable medium including instructions stored thereon, which when executed by at least one processor, configure the at least one processor to: retrieve, from at least one database, at least one independent claim of the patent as issued; retrieve, from the at least one database, at least one independent claim of the corresponding patent application as published; automatically compare the at least one issued independent claim to the at least one published independent claim by identifying at least one unique keyword present in the issued independent claim but not present in the published independent claim; cross-reference the at least one identified unique keyword to a passage in the specification of the issued patent, wherein the at least one identified unique keyword is cross-referenced to the passage in the specification of the issued patent using input received from a user interface; identify a first prior art document and a second prior art document; calculate an overlap score for the first prior art document based on at least one occurrence of the at least one unique key word in the first prior art document; calculate an overlap score for the second prior art document based on at least one occurrence of the at least one unique keyword in the second prior art document; calculate a ranking for the first prior art document by comparing the calculated overlap score of the first prior art document to the calculated overlap score of the second prior art document; and display, in the user interface, a graphical representation of the calculated overlap score of the first prior art document and a graphical representation of the calculated overlap score of the second prior art document based on the ranking, and the passage in the specification of the issued patent. 9. The at least one non-transitory computer-readable medium of claim 8 , further comprising instructions that, when executed by the at least one processor, configure the at least one processor to: identify at least one common keyword present in both of the at least one published independent claim and issued independent claim; and calculate the overlap score for the first prior art document based on at least one occurrence of the at least one common keyword in the first prior art document.
