What this shows Koatsu's Innovation Score is 23.7/100 (13th 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 Koatsu?

Each dot is one of Koatsu’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). Koatsu’s own 9.8 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Koatsu's grants concentrate

Koatsu Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A62C (Fire-fighting). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2017. By volume, Koatsu sits between Knowledge Development FOR POF, S.L. and KOK & VAN Engelen Composite Structures B.V..

Koatsu's three-year grant acceleration

Koatsu 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.
