USPTO PatentsView assignee record - 5 granted patents across 6 technology areas, active 2015–2019. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F17C (VESSELS FOR CONTAINING OR STORING COMPRESSED, LIQUEFIED OR SOLIDIFIED GASES; FIXED-CAPACITY GAS-HOLDERS; FILLING VESSELS WITH, OR DISCHARGING FROM VESSELS, COMPRESSED, LIQUEFIED, OR SOLIDIFIED GASES).
The verdict
Carleton holds 5 US patents across 6 technology areas, rank #45,750 of 50,000 tracked assignees.
Carleton Technologies, Inc. has been granted 5 US utility patents between 2015 and 2019, placing Carleton Technologies, Inc. at rank #45,750 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in F17C (VESSELS FOR CONTAINING OR STORING COMPRESSED, LIQUEFIED OR SOLIDIFIED GASES; FIXED-CAPACITY GAS-HOLDERS; FILLING VESSELS WITH, OR DISCHARGING FROM VESSELS, COMPRESSED, LIQUEFIED, OR SOLIDIFIED GASES). As a US Corporation, Carleton Technologies, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Carleton sits between Careerbuilder, Llc (5 patents, rank #45,746) and Carrygenes Bioengineering, Llc (5 patents, rank #45,754) - the closest US assignees by grant volume. The composite Innovation Score of 19.9/100 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 0 grants, compared with 5 in the 2015–2019 window, a -100% 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. Carleton Technologies, Inc.'s 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Carleton Technologies, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Carleton's 5 grants land it in the top 94% 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.
