Where Zhejiang's grants concentrate

Zhejiang Yotrio Group Co., Ltd. is a focused PatentsView assignee: 26 CPC subclasses with 32.1% of grants classified under A45B (Walking Sticks ; UMBRELLAS; Ladies' OR Like Fans). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2017. By volume, Zhejiang sits between Zhejiang Linix Motor Co., Ltd. and eIngot LLC.

Zhejiang's three-year grant acceleration

Zhejiang Yotrio Group Co., Ltd. shows 5 grants in 2022–2024 against only 16 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.
