Across all tracked assignees
USPTO PatentsView assignee record - 19 granted patents across 6 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F02B (INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL).
The verdict
Prometheus holds 19 US patents across 6 technology areas, rank #15,553 of 50,000 tracked assignees.
Prometheus Applied Technologies Llc has been granted 19 US utility patents between 2015 and 2025, placing Prometheus Applied Technologies Llc at rank #15,553 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.4 claims per patent with primary concentration in F02B (INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL). As a US Corporation, Prometheus Applied Technologies Llc is one of the more focused assignees in the PatentsView dataset. By volume, Prometheus sits between Precision, Inc. (19 patents, rank #15,549) and Quality EDGE, Inc. (19 patents, rank #15,557) - the closest US assignees by grant volume. The composite Innovation Score of 40.7/100 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 8 grants, compared with 11 in the 2015–2019 window, a -27% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Prometheus Applied Technologies Llc's 27.4 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 Prometheus Applied Technologies Llc against peers pursuing similar technology classes.

How to use this portfolio
Prometheus's 19 grants land it in the top 35% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
