What this shows Wenzhou's Innovation Score is 44.2/100 (top 26% 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 Wenzhou?

Each dot is one of Wenzhou’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). Wenzhou’s own 3.9 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wenzhou's grants concentrate

Wenzhou Furuisi Building Materials Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 13.6% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2024 (20 grants) versus a trough of 3 in 2023. By volume, Wenzhou sits between Valeo Siemens Eautomotive France SAS and Xcelsis Corporation.

Wenzhou's three-year grant acceleration

Wenzhou Furuisi Building Materials Co., Ltd. shows 23 grants in 2022–2024 against only 0 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.
