What this shows BTU's Innovation Score is 39.9/100 (top 37% 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 BTU?

Each dot is one of BTU’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). BTU’s own 12.0 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where BTU's grants concentrate

BTU International, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 37.5% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2021. By volume, BTU sits between Broadpeak and Balmoral Comtec Limited.

BTU's three-year grant acceleration

BTU International, Inc. shows 2 grants in 2022–2024 against only 1 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.
