What this shows National's Innovation Score is 50.7/100 (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 10.1 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How National's grant cadence moved

Between 2020–2024, National University Corporation Kumamoto University received 27 grants versus 39 in 2015–2019 (-31% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 10 grants and bottomed in 2024 at 2. Lead class C12N accounts for 30% of the portfolio across 73 subclasses. Volume neighbours: Lumenis Ltd. (#4,963) and Oatey Co. (#4,971).

National's three-year grant acceleration

National University Corporation Kumamoto University shows 14 grants in 2022–2024 against only 19 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.
