What this shows National's Innovation Score is 40.5/100 (top 35% 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 11.4 claims/patent is at or below the 14.5 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 Magaoka University OF Technology is a focused PatentsView assignee: 32 CPC subclasses with 31.6% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, National sits between Nanjing Silicon Intelligence Technology Co., Ltd. and NEW York Society FOR THE Ruptured AND Crippled, Maintaining THE Hospital FOR Special Surgery.
National's three-year grant acceleration
National University Corporation Magaoka University OF Technology shows 2 grants in 2022–2024 against only 4 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.
