Where Xuzhou's grants concentrate

Xuzhou Armour Rubber Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2021. By volume, Xuzhou sits between Xiamen iPrt Technology Co., Ltd. and Yanggu Xiangguang Copper Co., Ltd.

Xuzhou's three-year grant acceleration

Xuzhou Armour Rubber Co., Ltd. shows 4 grants in 2022–2024 against only 2 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.
