Does more volume mean deeper claims for Wuxi?

Each dot is one of Wuxi’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). Wuxi’s own 11.7 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 Wuxi's grants concentrate

Wuxi Esiontech Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (7 grants) versus a trough of 6 in 2023. By volume, Wuxi sits between Whealthfields (HONG KONG) Limited and Wenzhou Mtlc Electric Appliances Co., Ltd.

Wuxi's three-year grant acceleration

Wuxi Esiontech Co., Ltd. shows 13 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.
