What this shows Miki's Innovation Score is 28.0/100 (26th 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 Miki?

Each dot is one of Miki’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). Miki’s own 3.5 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Miki's grants concentrate

Miki Pulley Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 12.5% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Miki sits between Merits Health Products Co., Ltd. and Mobile Industrial Robots A/S.

Miki's three-year grant acceleration

Miki Pulley Co., Ltd. shows 2 grants in 2022–2024 against only 4 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.
