ABSTRACT

A method and system for automated patent analysis using machine learning techniques.
The invention provides a novel approach to extracting and categorizing patent claims.

CLAIMS

1. A method for patent analysis comprising:
   (a) extracting text from patent documents
   (b) identifying key sections using natural language processing
   (c) categorizing claims by technical domain

2. The method of claim 1, wherein the natural language processing uses
   transformer-based models.

3. The method of claim 1, wherein the system operates on a distributed
   computing infrastructure.

DETAILED DESCRIPTION

The present invention relates to patent analysis systems. In particular,
it provides an automated method for processing large volumes of patent
documents and extracting relevant information for commercialization assessment.

The system comprises multiple components including document processors,
machine learning models, and visualization tools.
