What this shows National's Innovation Score is 35.5/100 (top 49% 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 13.3 claims/patent is at or below the 14.1 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 Asahikawa Medical University is a focused PatentsView assignee: 17 CPC subclasses with 53.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, National sits between NAN Chang O-film Optoelectronics Technology Ltd and Neuchips Corporation.

National's three-year grant acceleration

National University Corporation Asahikawa Medical University shows 3 grants in 2022–2024 against only 6 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.
