What this shows Thermax's Innovation Score is 31.1/100 (37th 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 Thermax?

Each dot is one of Thermax’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). Thermax’s own 13.6 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Thermax's grants concentrate

Thermax Limited is a focused PatentsView assignee: 15 CPC subclasses with 88.9% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2016. By volume, Thermax sits between THE Monadnock Company and Thorne Intellectual Property Holdings LLC.

Thermax's three-year grant acceleration

Thermax Limited shows 1 grants in 2022–2024 against only 5 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.
