Method and System of Extracting Patent Features for Comparison and to Determine Similarities, novelty and Obviousness

摘要

An automated system that extract relevant structural and functional features from a patent document and carries out operations on patent documents to determine degree of overlap. The degree of overlap can then be used by the system to determine novelty and obviousness of a patent document.

主权项

1. A computer representations of structural and functional elements in patent documents represented by the representation of a graph composed of nodes and links through a method comprising of:
a searchable invention document comprising a body, wherein said body comprises a body narrative; selecting a searchable document, wherein said document comprises at least a claim, wherein said claim comprises a claim preamble and a claim narrative; a first set of instruction for parsing of the body, wherein said first set of instructions comprises the extraction of a plurality of element from said body narrative, wherein each element of said plurality element is identified as node for said body; a second set of instruction for parsing of the body, wherein said second set of instructions extracts the links between the plurality of elements; a third set of instruction for parsing the claim narrative to obtain the preamble from the claim narrative using match phrases; a fourth set of instruction for parsing the claim narrative to obtain claim nodes using match phrases; and a fifth set of instruction for classifying each of the claims nodes and nodes in a first group and a second group; and wherein said group is structural elements and the second group is functional elements.
