What this shows National's Innovation Score is 51.6/100 (top 11% 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 9.6 claims/patent is at or below the 11.0 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 Toyohashi University OF Technology received 16 grants versus 25 in 2015–2019 (-36% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2018 at 9 grants and bottomed in 2019 at 1. Lead class G01N accounts for 39.1% of the portfolio across 52 subclasses. Volume neighbours: Mustang Sampling, LLC (#7,164) and Oblong Industries, Inc. (#7,172).

National's three-year grant acceleration

National University Corporation Toyohashi University OF Technology shows 9 grants in 2022–2024 against only 8 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.
