What this shows National's Innovation Score is 49.5/100 (top 15% 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 15.2 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 Ehime University received 19 grants versus 17 in 2015–2019 (+12% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2016 at 8 grants and bottomed in 2015 at 1. Lead class G01N accounts for 26.8% of the portfolio across 58 subclasses. Volume neighbours: Mylan Inc. (#7,891) and NuVolta Technologies (Hefei) Co., Ltd. (#7,899).

National's three-year grant acceleration

National University Corporation Ehime University 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.
