Portfolio overview

Thermatool Corp. has been granted 9 US utility patents between 2015 and 2023, placing Thermatool Corp. at rank #30,406 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.9 claims per patent with primary concentration in B23K (SOLDERING OR UNSOLDERING; WELDING; CLADDING OR PLATING BY SOLDERING OR WELDING; CUTTING BY APPLYING HEAT LOCALLY, e.g. FLAME CUTTING; WORKING BY LASER BEAM). As a US Corporation, Thermatool Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Thermatool sits between The Steel Network, Inc. (9 patents, rank #30,402) and Tianjin Hemay Bio-tech Co., Ltd. (9 patents, rank #30,410) - 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 4 grants, compared with 5 in the 2015–2019 window, a -20% 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. Thermatool Corp.'s 17.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Thermatool Corp. 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.
