What this shows U-shin's Innovation Score is 42.1/100 (top 31% 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 U-shin?

Each dot is one of U-shin’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). U-shin’s own 7.7 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where U-shin's grants concentrate

U-shin Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 40.9% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2024. By volume, U-shin sits between Terves, LLC and Universitat POLITÉCNICA DE Catalunya.

U-shin's three-year grant acceleration

U-shin Ltd. shows 11 grants in 2022–2024 against only 11 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.
