What this shows Kagoshima's Innovation Score is 47.3/100 (top 19% 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 Kagoshima?

Each dot is one of Kagoshima’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). Kagoshima’s own 11.5 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kagoshima's grants concentrate

Kagoshima University is a focused PatentsView assignee: 39 CPC subclasses with 44% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2018. By volume, Kagoshima sits between KHN Solutions, LLC and Mftb Holdco, Inc..

Kagoshima's three-year grant acceleration

Kagoshima University shows 12 grants in 2022–2024 against only 17 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.
