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 16.6 claims/patent is ABOVE the 7.1 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 Huachengda Precision Industry Co. Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 90% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). By volume, Shenzhen sits between Shenzhen Diepin Technology Co., Ltd. and Shenzhen Ocean's King Lighting Engineering Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Huachengda Precision Industry Co. Ltd. shows 5 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.
