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

A system for determining where in a plurality of references a limitation of a patent claim is described by a computing device, the system comprising:

• one or more memories having computer readable computer instructions;
• and
• one or more processors for executing the computer readable computer instructions to perform a method comprising:
• indexing the reference to create a plurality of search documents;
• building a search index from the plurality of search documents;
• generating a query from the limitation;
• executing a search in the search index for search documents that match the query;
• and
• outputting a result, comprising a search document that matches the query and a relevancy score representing a relevancy of the search document to the query.

One or more non-transitory computer-readable storage medium containing machine-readable computer instructions that, when executed by a processing device, perform a method of determining where in a plurality of references a limitation of a patent claim is described by a computing device, the method comprising:

• indexing the reference to create a plurality of search documents;
• building a search index from the plurality of search documents;
• generating a query from the limitation;
• executing a search in the search index for search documents that match the query;
• and
• outputting a result, comprising a search document that matches the query and a relevancy score representing a relevancy of the search document to the query.
