What this shows National's Innovation Score is 36.3/100 (top 47% 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 11.8 claims/patent is ABOVE the 10.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where National's grants concentrate

National University Corporation Shiga University OF Medical Science is a focused PatentsView assignee: 11 CPC subclasses with 63.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2016. By volume, National sits between National Center FOR Nanoscience AND Technology and NDM Technologies Limited.

National's three-year grant acceleration

National University Corporation Shiga University OF Medical Science shows 4 grants in 2022–2024 against only 3 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.
