Abstract

A method for processing patent text (99) in a computer (200) including identifying boundaries of parts of patent text (100), loading at least one of the parts of the patent text into a working memory (102), analyzing at least one of the parts of the patent text (104), and reporting results (106) to a user (202). Alphanumeric drawing data can also be compared to patent text (100). The method can be coupled to work with a word processor program (208). The method can recognize and report (106 and 708) on claim dependency (400, 402, 404), specific characteristics (704) of patent text (99), and patent errors based on legal standards, practice standards, and Patent and Trademark Office standards, or even user preferences (702, 704, 706).
