What this shows Carbon's Innovation Score is 41.3/100 (top 34% 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 17.0 claims/patent is ABOVE the 16.2 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 Sink Inc. is a focused PatentsView assignee: 20 CPC subclasses with 100% of grants classified under Y02C (Capture, Storage, Sequestration OR Disposal OF Greenhouse Gases [GHG]). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, Carbon sits between Capat LLC and Casetext, Inc..

Carbon's three-year grant acceleration

Carbon Sink Inc. shows 1 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.
