What this shows Asahi's Innovation Score is 44.3/100 (top 26% 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 Asahi's grants concentrate

Asahi Seiko Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 55.8% of grants classified under G07D (Handling OF Coins OR Valuable Papers, e.g. Testing, Sorting BY Denominations, Counting, Dispensing, Changing OR Depositing). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2020. By volume, Asahi sits between Aiphone Co., Ltd. and Anumana, Inc..

Asahi's three-year grant acceleration

Asahi Seiko Co., Ltd. shows 16 grants in 2022–2024 against only 8 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.
