What this shows Carbon's Innovation Score is 31.1/100 (36th 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 Carbon?

Each dot is one of Carbon’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). Carbon’s own 16.5 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carbon's grants concentrate

Carbon AIR Limited is a focused PatentsView assignee: 8 CPC subclasses with 50% of grants classified under F16F (SPRINGS; SHOCK-ABSORBERS; Means FOR Damping Vibration). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Carbon sits between Canberra Industries, Inc. and Carboshield, Inc..

Carbon's three-year grant acceleration

Carbon AIR Limited shows 2 grants in 2022–2024 against only 3 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.
