What this shows Ciel's Innovation Score is 35.6/100 (top 49% 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 Ciel?

Each dot is one of Ciel’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). Ciel’s own 22.4 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ciel's grants concentrate

Ciel ET Terre International is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). By volume, Ciel sits between CHS Healthcare Ventures, Inc. and Ciris Energy, Inc.

Ciel's three-year grant acceleration

Ciel ET Terre International shows 1 grants in 2022–2024 against only 0 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.
