Where Shenzhen's grants concentrate

Shenzhen Huamingjun Rubber Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 40% of grants classified under A63H (Toys, e.g. Tops, Dolls, Hoops OR Building Blocks). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Shenzhen sits between Shenzhen Dixuan Science & Technology Co., Ltd and Shenzhen Pango Microsystems Co., Ltd..

Shenzhen's three-year grant acceleration

Shenzhen Huamingjun Rubber Co., Ltd shows 3 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.
