What this shows Kurashiki's Innovation Score is 28.1/100 (26th 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 Kurashiki?

Each dot is one of Kurashiki’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). Kurashiki’s own 5.9 claims/patent is at or below the 10.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kurashiki's grants concentrate

Kurashiki Kako Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 77.8% of grants classified under F16F (SPRINGS; SHOCK-ABSORBERS; Means FOR Damping Vibration). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Kurashiki sits between KRL Holding Company, Inc. and KacePack, Ltd..

Kurashiki's three-year grant acceleration

Kurashiki Kako Co., Ltd. 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.
