What this shows Kabushiki's Innovation Score is 38.3/100 (top 41% 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 7.7 claims/patent is at or below the 8.1 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 TOP is a focused PatentsView assignee: 18 CPC subclasses with 29.3% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2024 (8 grants) versus a trough of 2 in 2015. By volume, Kabushiki sits between Japan Polyethylene Corporation and Keyssa Systems, Inc..

Kabushiki's three-year grant acceleration

Kabushiki Kaisha TOP shows 13 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.
