Across all tracked assignees
USPTO PatentsView assignee record - 7 granted patents across 4 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F24S (SOLAR HEAT COLLECTORS; SOLAR HEAT SYSTEMS).
The verdict
Thermal holds 7 US patents across 4 technology areas, rank #37,981 of 50,000 tracked assignees.
Thermal Storage Systems has been granted 7 US utility patents between 2017 and 2025, placing Thermal Storage Systems at rank #37,981 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.6 claims per patent with primary concentration in F24S (SOLAR HEAT COLLECTORS; SOLAR HEAT SYSTEMS). As a US Corporation, Thermal Storage Systems is one of the more focused assignees in the PatentsView dataset. By volume, Thermal sits between The Willamette Valley Company Llc (7 patents, rank #37,977) and Thinx Inc. (7 patents, rank #37,985) - the closest US assignees by grant volume. The composite Innovation Score of 35.1/100 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 4 grants, compared with 3 in the 2015–2019 window, a +33% 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. Thermal Storage Systems's 23.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Thermal Storage Systems against peers pursuing similar technology classes.

How to use this portfolio
Thermal's 7 grants land it in the top 50% 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.
