What this shows Kanken's Innovation Score is 36.4/100 (top 47% 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.

Where Kanken's grants concentrate

Kanken Techno Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 100% of grants classified under B01D (Separation). By volume, Kanken sits between Kandy Therapeutics Limited and Kari-out LLC.

Kanken's three-year grant acceleration

Kanken Techno Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
