Does more volume mean deeper claims for Carbonfree?
Each dot is one of Carbonfree’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). Carbonfree’s own 13.7 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Carbonfree's grants concentrate
Carbonfree Chemicals Holdings, LLC is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under Y02C (Capture, Storage, Sequestration OR Disposal OF Greenhouse Gases [GHG]). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2020. By volume, Carbonfree sits between Canimguide Therapeutics AB and Cargometrics Technologies, LLC.
Carbonfree's three-year grant acceleration
Carbonfree Chemicals Holdings, LLC shows 3 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.
