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 14.9 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 Carbon's grants concentrate

Carbon Free Holdings LLC is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Carbon sits between Capella Therapeutics, Inc. and CCA and B, LLC.

Carbon's three-year grant acceleration

Carbon Free Holdings LLC shows 6 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.
