What this shows Shenzhen's Innovation Score is 34.1/100 (46th 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 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 5.4 claims/patent is at or below the 9.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shenzhen's grants concentrate

Shenzhen Smaco Technology Limited is a focused PatentsView assignee: 5 CPC subclasses with 46.7% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2017. By volume, Shenzhen sits between Shenzhen Dansha Technology Co., Ltd. and Skychase Holdings Corporation.

Shenzhen's three-year grant acceleration

Shenzhen Smaco Technology Limited shows 2 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.
