What this shows Kikusui's Innovation Score is 40.3/100 (top 36% 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 Kikusui?

Each dot is one of Kikusui’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). Kikusui’s own 18.1 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kikusui's grants concentrate

Kikusui Seisakusho Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 95.8% of grants classified under B30B (Presses IN General). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2015. By volume, Kikusui sits between Jasco Corporation and Korea Institute OF Science & Technology Information.

Kikusui's three-year grant acceleration

Kikusui Seisakusho Ltd. shows 6 grants in 2022–2024 against only 12 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.
