What this shows Tokuyama's Innovation Score is 47.9/100 (top 18% 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 10.1 claims/patent is at or below the 11.8 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 Sekisui Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2018. By volume, Tokuyama sits between Technogel Italia S.R.L. and TOX Pressotechnik GMBH & Co. KG.

Tokuyama's three-year grant acceleration

Tokuyama Sekisui Co., Ltd. shows 8 grants in 2022–2024 against only 1 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.
