What this shows Riken's Innovation Score is 25.4/100 (17th percentile 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 Riken?

Each dot is one of Riken’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). Riken’s own 5.3 claims/patent is at or below the 19.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Riken's grants concentrate

Riken Vitamin Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 85.7% of grants classified under A23L (Foods, Foodstuffs OR Non-alcoholic Beverages, NOT Otherwise Provided FOR; Preparation OR Treatment Thereof). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2017. By volume, Riken sits between Rhodan Marine Systems of Florida, LLC and Robbins, Inc..

Riken's three-year grant acceleration

Riken Vitamin Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
