As a US Corporation, Enfield Engine Company, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.6/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
