What this shows Weihai's Innovation Score is 36.5/100 (top 46% 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 Weihai?

Each dot is one of Weihai’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). Weihai’s own 10.3 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Weihai's grants concentrate

Weihai Winner Innovation Ocean Technology Co., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 66.7% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, Weihai sits between Weaver Leather, LLC and Wenzhou Yuanfei PET TOY Products Co., Ltd..

Weihai's three-year grant acceleration

Weihai Winner Innovation Ocean Technology Co., Ltd shows 3 grants in 2022–2024 against only 1 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.
