What this shows Kanagawa's Innovation Score is 44.7/100 (top 25% 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 Kanagawa?

Each dot is one of Kanagawa’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). Kanagawa’s own 10.8 claims/patent is ABOVE the 7.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kanagawa's grants concentrate

Kanagawa University is a focused PatentsView assignee: 31 CPC subclasses with 27.8% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2015. By volume, Kanagawa sits between Jiangxi Lianyi Optics Co., Ltd. and KGS Jewels, Inc..

Kanagawa's three-year grant acceleration

Kanagawa University shows 5 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.
