What this shows CAO's Innovation Score is 39.5/100 (top 38% 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 CAO?

Each dot is one of CAO’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). CAO’s own 9.3 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CAO's grants concentrate

CAO Group, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 41.2% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2018. By volume, CAO sits between Buckingham Manufacturing Company, Inc. and Ceat Limited.

CAO's three-year grant acceleration

CAO Group, Inc. shows 7 grants in 2022–2024 against only 8 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.
