What this shows Wooshin's Innovation Score is 25.2/100 (17th 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 Wooshin?

Each dot is one of Wooshin’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). Wooshin’s own 11.3 claims/patent is at or below the 17.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wooshin's grants concentrate

Wooshin Safety Systems Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 90% of grants classified under B60R (Vehicles, Vehicle Fittings, OR Vehicle Parts, NOT Otherwise Provided FOR). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Wooshin sits between Winview IP Holdings, LLC and Xcella Biosciences, Inc..

Wooshin's three-year grant acceleration

Wooshin Safety Systems Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
