What this shows Thermolon's Innovation Score is 29.7/100 (32nd 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 Thermolon?

Each dot is one of Thermolon’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). Thermolon’s own 11.1 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Thermolon's grants concentrate

Thermolon Korea Co. Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 57.1% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2024. By volume, Thermolon sits between Therasyn Sensors, Inc. and Thinkon NEW Technology Japan Corporation.

Thermolon's three-year grant acceleration

Thermolon Korea Co. Ltd. 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.
