What this shows Carus's Innovation Score is 31.7/100 (39th 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 Carus?

Each dot is one of Carus’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). Carus’s own 15.6 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carus's grants concentrate

Carus LLC is a focused PatentsView assignee: 11 CPC subclasses with 40% of grants classified under B09C (Reclamation OF Contaminated Soil). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, Carus sits between Carollo Engineers, Inc. and Cata, LLC.

Carus's three-year grant acceleration

Carus LLC 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.
