What this shows Shenzhen's Innovation Score is 45.2/100 (top 24% 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 11.6 claims/patent is ABOVE the 3.3 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 Happy Vaping Technology Limited is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2018. By volume, Shenzhen sits between Shenzhen Fastprint Circuit Tech Co., Ltd. and Shenzhen LIYI99.COM, Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Happy Vaping Technology Limited shows 6 grants in 2022–2024 against only 1 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.
