What this shows National's Innovation Score is 67.0/100 (top 1% 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 10.4 claims/patent is at or below the 14.7 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

Grant history spans 2020–2025. Across complete PatentsView years, output peaked in 2024 at 27 grants and bottomed in 2020 at 4. Lead class B82Y accounts for 20.2% of the portfolio across 103 subclasses. Volume neighbours: Mbit Wireless, Inc. (#3,850) and SUN Yat-sen University (#3,858).

National's three-year grant acceleration

National University Corporation Tokai National Higher Education AND Research System shows 62 grants in 2022–2024 against only 9 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.
