What this shows Kuroda's Innovation Score is 37.3/100 (top 44% 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 Kuroda?

Each dot is one of Kuroda’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). Kuroda’s own 7.8 claims/patent is at or below the 13.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kuroda's grants concentrate

Kuroda Precision Industries Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 61.3% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2022 (6 grants) versus a trough of 2 in 2016. By volume, Kuroda sits between Kyosan Denki Co., Ltd. and Leatherman Tool Group, Inc..

Kuroda's three-year grant acceleration

Kuroda Precision Industries Ltd. shows 10 grants in 2022–2024 against only 11 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.
