What this shows Kabushiki's Innovation Score is 28.5/100 (27th 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 Kabushiki?

Each dot is one of Kabushiki’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). Kabushiki’s own 4.7 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kabushiki's grants concentrate

Kabushiki Kaisha Aichi Corporation is a focused PatentsView assignee: 11 CPC subclasses with 24.1% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2019. By volume, Kabushiki sits between Jentek Sensors, Inc. and Koolbridge Solar, Inc..

Kabushiki's three-year grant acceleration

Kabushiki Kaisha Aichi Corporation shows 5 grants in 2022–2024 against only 15 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.
