What this shows Shenzhen's Innovation Score is 40.7/100 (top 35% 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 Shenzhen?

Each dot is one of Shenzhen’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). Shenzhen’s own 17.5 claims/patent is ABOVE the 7.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenzhen's grants concentrate

Shenzhen Dansha Technology Co., Ltd. is a focused PatentsView assignee: 32 CPC subclasses with 33.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2022. By volume, Shenzhen sits between Servore Co., Ltd. and Shenzhen Smaco Technology Limited.

Shenzhen's three-year grant acceleration

Shenzhen Dansha Technology Co., Ltd. shows 1 grants in 2022–2024 against only 11 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.
