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 2.7 claims/patent is at or below the 14.7 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 Mtlc Electric Appliances Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 16.7% of grants classified under H03K (Pulse Technique). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2016. By volume, Wenzhou sits between Wuxi Esiontech Co., Ltd. and X-Spine Systems, Inc..

Wenzhou's three-year grant acceleration

Wenzhou Mtlc Electric Appliances Co., Ltd shows 1 grants in 2022–2024 against only 10 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.
