What this shows Fives's Innovation Score is 35.1/100 (top 50% 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 Fives?

Each dot is one of Fives’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). Fives’s own 14.1 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Fives's grants concentrate

Fives North American Combustion, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under F23C (Methods OR Apparatus FOR Combustion Using Fluid Fuel OR Solid Fuel Suspended IN ; A Carrier GAS OR; AIR). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, Fives sits between Fero Corporation and FluGen, Inc..

Fives's three-year grant acceleration

Fives North American Combustion, Inc. shows 3 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.
