What this shows National's Innovation Score is 47.1/100 (top 19% 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 14.2 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 Yamagata University is a focused PatentsView assignee: 43 CPC subclasses with 43.8% of grants classified under H10K (Organic Electric Solid-state Devices). Peak complete grant year is 2020 (5 grants) versus a trough of 3 in 2016. By volume, National sits between Nippon Zoki Pharmaceutical Co., Ltd. and OrthoPediatrics Corp..

National's three-year grant acceleration

National University Corporation Yamagata University shows 8 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.
