What this shows Chapman's Innovation Score is 44.4/100 (top 26% 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 Chapman?

Each dot is one of Chapman’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). Chapman’s own 13.0 claims/patent is at or below the 17.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chapman's grants concentrate

Chapman University is a focused PatentsView assignee: 6 CPC subclasses with 66.7% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2022. By volume, Chapman sits between Central Adelaide Local Health Network Incorporated and Cheetah Medical, Inc..

Chapman's three-year grant acceleration

Chapman University shows 8 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.
