1. A computer implemented method to analyze a patent document, comprising: generating a claim tree showing inter-claim relationship between descendant and parent claims; utilizing an interface so that when a user selects a claim a graphical representation of the inter-claim relationship is diagrammed; moving claims when requested by the user, the claim tree visualizes the inter-claim relationship, wherein moving the claim by using drag and drop selection the claims will automatically be renumbered to show their new inter-claim relationship; adjusting claims when selected, added, or deleted, wherein all other claims will be automatically be adjusted and renumbered; and checking the claims for antecedent and support in drawings and support in description; and indexing terms in the claims, along with automatically detecting and displaying a claim number from a claim text and claim status as independent claim type or dependent claim type; and identifying broader and narrower terms, and prompting a user whether a predetermined element is necessary or whether the predetermined element is not needed in a design around.
