What this shows Usui's Innovation Score is 35.6/100 (top 49% 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 Usui?

Each dot is one of Usui’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). Usui’s own 5.4 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Usui's grants concentrate

Usui Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 70.4% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2018. By volume, Usui sits between Umicore Shokubai Japan Co., Ltd. and Veea Inc..

Usui's three-year grant acceleration

Usui Co., Ltd. shows 8 grants in 2022–2024 against only 17 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.
