What this shows Kawajun's Innovation Score is 31.7/100 (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 Kawajun?

Each dot is one of Kawajun’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). Kawajun’s own 7.7 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kawajun's grants concentrate

Kawajun Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 50% of grants classified under A47B (TABLES; DESKS; Office FURNITURE; CABINETS; DRAWERS; General Details OF Furniture). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2017. By volume, Kawajun sits between Kanazawa University and KCl Licensing, Inc..

Kawajun's three-year grant acceleration

Kawajun Co., Ltd. shows 2 grants in 2022–2024 against only 0 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.
