What this shows Kurosawa's Innovation Score is 21.3/100 (8th 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 Kurosawa?

Each dot is one of Kurosawa’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). Kurosawa’s own 3.8 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kurosawa's grants concentrate

Kurosawa Construction Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 80% of grants classified under E04C (Structural ELEMENTS; Building Materials). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2017. By volume, Kurosawa sits between Kulr Technology Corporation and KWC AG.

Kurosawa's three-year grant acceleration

Kurosawa Construction Co., Ltd. shows 2 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.
