What this shows Koyo's Innovation Score is 27.1/100 (23rd 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 Koyo?

Each dot is one of Koyo’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). Koyo’s own 5.8 claims/patent is at or below the 10.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Koyo's grants concentrate

Koyo Machine Industries Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 54.5% 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 2020. By volume, Koyo sits between Korea Fuel-tech Corporation and Kwai Inc..

Koyo's three-year grant acceleration

Koyo Machine Industries Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
