Xiamen Roadzup Outdoor Products Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 72.7% of grants classified under E04H (BUILDINGS OR LIKE STRUCTURES FOR PARTICULAR PURPOSES; SWIMMING OR SPLASH BATHS OR POOLS; MASTS; FENCING; TENTS OR CANOPIES, IN GENERAL). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, Xiamen sits between Xuanwu Hospital Capital Medical University and YKK Corporation Of America.
Xiamen Roadzup Outdoor Products Co., Ltd. shows 1 grants in 2022–2024 against only 5 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.
