What this shows Yutaka's Innovation Score is 31.5/100 (38th 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 Yutaka?

Each dot is one of Yutaka’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). Yutaka’s own 7.9 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yutaka's grants concentrate

Yutaka Giken Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 41.2% of grants classified under F16H (Gearing). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Yutaka sits between Xiant Technologies, Inc. and Zhejiang Jiansheng Leisure Products Co., Ltd.

Yutaka's three-year grant acceleration

Yutaka Giken Co., Ltd. shows 2 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.
