What this shows Inductotherm's Innovation Score is 42.7/100 (top 30% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Inductotherm's grants concentrate

Inductotherm Corp. is a focused PatentsView assignee: 20 CPC subclasses with 56.8% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2016 (9 grants) versus a trough of 1 in 2021. By volume, Inductotherm sits between Idex Biometrics ASA and Kaltenbach & Voigt GMBH.

Inductotherm's three-year grant acceleration

Inductotherm Corp. shows 6 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
