What this shows Shoei's Innovation Score is 62.6/100 (top 2% 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 Shoei?

Each dot is one of Shoei’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). Shoei’s own 12.8 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shoei's grants concentrate

Shoei Chemical Inc. is a focused PatentsView assignee: 47 CPC subclasses with 37.5% of grants classified under B82Y (Specific Uses OR Applications OF NANOSTRUCTURES; Measurement OR Analysis OF NANOSTRUCTURES; Manufacture OR Treatment OF Nanostructures). Peak complete grant year is 2024 (20 grants) versus a trough of 3 in 2017. By volume, Shoei sits between Samyang Holdings Corporation and Sococo, LLC.

Shoei's three-year grant acceleration

Shoei Chemical Inc. shows 31 grants in 2022–2024 against only 13 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.
