What this shows Tokuyama's Innovation Score is 42.9/100 (top 29% 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 Tokuyama?

Each dot is one of Tokuyama’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). Tokuyama’s own 7.9 claims/patent is at or below the 12.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tokuyama's grants concentrate

Tokuyama Dental Corporation is a focused PatentsView assignee: 28 CPC subclasses with 72.5% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (9 grants) versus a trough of 2 in 2016. By volume, Tokuyama sits between T.J.Smith and Nephew, Limited and Toshiba Electron Tubes & Devices Co., Ltd..

Tokuyama's three-year grant acceleration

Tokuyama Dental Corporation shows 14 grants in 2022–2024 against only 16 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.
