What this shows Kanazawa's Innovation Score is 27.0/100 (22nd percentile 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 Kanazawa?

Each dot is one of Kanazawa’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). Kanazawa’s own 7.8 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kanazawa's grants concentrate

Kanazawa University is a focused PatentsView assignee: 12 CPC subclasses with 33.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2020. By volume, Kanazawa sits between Kaltech Corporation and Kawajun Co., Ltd..

Kanazawa's three-year grant acceleration

Kanazawa University shows 1 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.
