What this shows National's Innovation Score is 50.3/100 (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 National?
Each dot is one of National’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). National’s own 12.4 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where National's grants concentrate
National University Corporation University of Toyama is a focused PatentsView assignee: 44 CPC subclasses with 25.5% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2021. By volume, National sits between Metso Minerals, Inc. and Rotam Agrochem International Company Limited.
National's three-year grant acceleration
National University Corporation University of Toyama shows 10 grants in 2022–2024 against only 12 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.
