What this shows Tokushima's Innovation Score is 41.0/100 (top 34% 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 Tokushima?

Each dot is one of Tokushima’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). Tokushima’s own 11.3 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tokushima's grants concentrate

Tokushima University is a focused PatentsView assignee: 28 CPC subclasses with 42.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2023. By volume, Tokushima sits between Spiration, Inc. and Technical University of Denmark.

Tokushima's three-year grant acceleration

Tokushima University shows 8 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.
