What this shows Wuxi's Innovation Score is 24.3/100 (14th percentile 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 5.6 claims/patent is at or below the 17.6 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 Kaishun Medical Device Manufacturing Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 28.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2018. By volume, Wuxi sits between Will Semiconductor (SHANGHAI) Co. Ltd. and WaveTec Vision Systems, Inc..

Wuxi's three-year grant acceleration

Wuxi Kaishun Medical Device Manufacturing Co., Ltd. shows 4 grants in 2022–2024 against only 6 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.
