Portfolio overview

Inductotherm Corp. has been granted 37 US utility patents between 2015 and 2025, placing Inductotherm Corp. at rank #8,613 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a US Corporation, Inductotherm Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Inductotherm sits between IDEX Biometrics ASA (37 patents, rank #8,609) and Kaltenbach & Voigt Gmbh (37 patents, rank #8,617) - the closest US assignees by grant volume. The composite Innovation Score of 42.7/100 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 13 grants, compared with 24 in the 2015–2019 window, a -46% 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. Inductotherm Corp.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Inductotherm 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.
