Portfolio overview
Enfield Engine Company, Inc. has been granted 6 US utility patents between 2016 and 2023, placing Enfield Engine Company, Inc. at rank #40,082 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 30.0 claims per patent with primary concentration in F16C (SHAFTS; FLEXIBLE SHAFTS; ELEMENTS OR CRANKSHAFT MECHANISMS; ROTARY BODIES OTHER THAN GEARING ELEMENTS; BEARINGS). As a US Corporation, Enfield Engine Company, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Enfield sits between Energenesis Biomedical Co., Ltd. (6 patents, rank #40,078) and Enmotus, Inc. (6 patents, rank #40,086) - the closest US assignees by grant volume. 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.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 3 grants, compared with 3 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Enfield Engine Company, Inc.'s 30.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Enfield Engine Company, Inc. against peers pursuing similar technology classes.
