What this shows Sinwa's Innovation Score is 20.5/100 (7th 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 Sinwa?

Each dot is one of Sinwa’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). Sinwa’s own 4.5 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sinwa's grants concentrate

Sinwa Corporation is a focused PatentsView assignee: 4 CPC subclasses with 58.3% of grants classified under A45D (Hairdressing OR Shaving Equipment ; Equipment FOR Cosmetics OR Cosmetic Treatments, e.g. FOR Manicuring OR Pedicuring). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2018. By volume, Sinwa sits between Sillajen Biotherapeutics, Inc. and Skky, LLC.

Sinwa's three-year grant acceleration

Sinwa Corporation shows 2 grants in 2022–2024 against only 7 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.
