What this shows Niigata's Innovation Score is 50.6/100 (top 13% 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 Niigata?

Each dot is one of Niigata’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). Niigata’s own 11.2 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Niigata's grants concentrate

Niigata University is a focused PatentsView assignee: 47 CPC subclasses with 47.1% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2018. By volume, Niigata sits between Neofect Co., Ltd. and Neuronetics, Inc..

Niigata's three-year grant acceleration

Niigata University shows 11 grants in 2022–2024 against only 10 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.
