What this shows Wenhou's Innovation Score is 47.6/100 (top 18% 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 Wenhou?

Each dot is one of Wenhou’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). Wenhou’s own 11.2 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wenhou's grants concentrate

Wenhou University is a focused PatentsView assignee: 16 CPC subclasses with 50% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2021. By volume, Wenhou sits between Wellstat Diagnostics, LLC and West Liberty Foods, LLC.

Wenhou's three-year grant acceleration

Wenhou University 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.
