What this shows Wuxi's Innovation Score is 38.5/100 (top 41% 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 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 13.2 claims/patent is at or below the 15.3 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 Chipown Microelectronics Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 81.8% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, Wuxi sits between World Class Technology Corporation and Xiaomi Communications Co., Ltd..

Wuxi's three-year grant acceleration

Wuxi Chipown Microelectronics Co., Ltd. shows 6 grants in 2022–2024 against only 3 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.
