Systems and methods for analyzing the validity or infringment of patent claims

The invention describes a computer-based method to check if a patent claim's specific details are found in other documents. It works by breaking down those documents into smaller searchable pieces, creating a search index, then turning the patent claim's detail into a search query. The system then searches the index and provides matching documents along with a relevance score, specifically by splitting the original document into parts, each containing only some of the original text, and noting where each piece came from.
