What this shows Thermatool's Innovation Score is 32.6/100 (42nd percentile 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.

Does more volume mean deeper claims for Thermatool?

Each dot is one of Thermatool’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Thermatool’s own 17.9 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Thermatool's grants concentrate

Thermatool Corp. is a focused PatentsView assignee: 12 CPC subclasses with 44.4% of grants classified under 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). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2019. By volume, Thermatool sits between The Steel Network, Inc. and Tianjin Hemay Bio-Tech Co., Ltd..

Thermatool's three-year grant acceleration

Thermatool Corp. shows 1 grants in 2022–2024 against only 4 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.
