What this shows Ogura's Innovation Score is 26.9/100 (22nd 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 Ogura?

Each dot is one of Ogura’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). Ogura’s own 6.9 claims/patent is at or below the 9.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ogura's grants concentrate

Ogura Clutch Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 85.7% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, Ogura sits between Oblamatik AG and OME Technology Co., Ltd..

Ogura's three-year grant acceleration

Ogura Clutch Co., Ltd shows 3 grants in 2022–2024 against only 5 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.
