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.

Does more volume mean deeper claims for Asahi?

Each dot is one of Asahi’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). Asahi’s own 10.3 claims/patent is ABOVE the 9.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
