What this shows Kaga's Innovation Score is 31.8/100 (39th 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 Kaga?

Each dot is one of Kaga’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). Kaga’s own 12.6 claims/patent is ABOVE the 8.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kaga's grants concentrate

Kaga Works Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 72.7% of grants classified under B05C (Apparatus FOR Applying Fluent Materials TO Surfaces, IN General). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2015. By volume, Kaga sits between Joylux, Inc. and Kapman AB.

Kaga's three-year grant acceleration

Kaga Works Co., Ltd. shows 2 grants in 2022–2024 against only 4 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.
