What this shows Combustion's Innovation Score is 49.1/100 (top 15% 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 Combustion?

Each dot is one of Combustion’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). Combustion’s own 22.6 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Combustion's grants concentrate

Combustion Research and Flow Technology, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under F02C (Gas-turbine PLANTS; AIR Intakes FOR Jet-propulsion PLANTS; Controlling Fuel Supply IN Air-breathing Jet-propulsion Plants). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Combustion sits between Combain Mobile AB and Commonwealth Fusion Systems LLC.

Combustion's three-year grant acceleration

Combustion Research and Flow Technology, Inc. shows 4 grants in 2022–2024 against only 0 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.
