What this shows Kogakuin's Innovation Score is 53.3/100 (top 9% 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 Kogakuin?

Each dot is one of Kogakuin’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). Kogakuin’s own 8.6 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kogakuin's grants concentrate

Kogakuin University is a focused PatentsView assignee: 28 CPC subclasses with 14.3% of grants classified under G06N (Computing Arrangements Based ON Specific Computational Models). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2021. By volume, Kogakuin sits between Kingston Technology Corporation and Kwai Games PTE. Ltd..

Kogakuin's three-year grant acceleration

Kogakuin University shows 9 grants in 2022–2024 against only 2 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.
