Portfolio overview

Electratherm, Inc. has been granted 11 US utility patents between 2015 and 2018, placing Electratherm, Inc. at rank #24,277 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.2 claims per patent with primary concentration in F01K (STEAM ENGINE PLANTS; STEAM ACCUMULATORS; ENGINE PLANTS NOT OTHERWISE PROVIDED FOR; ENGINES USING SPECIAL WORKING FLUIDS OR CYCLES). As a US Corporation, Electratherm, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Electratherm sits between Ecolibrium Solar, Inc. (11 patents, rank #24,273) and Eleven Street Co., Ltd. (11 patents, rank #24,281) - the closest US assignees by grant volume. The composite Innovation Score of 36.8/100 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 11 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. Electratherm, Inc.'s 27.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Electratherm, Inc. against peers pursuing similar technology classes.

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.
