Where Zezhi's grants concentrate

Zezhi Intellectual Property Service is a focused PatentsView assignee: 11 CPC subclasses with 62.5% of grants classified under A23L (Foods, Foodstuffs OR Non-alcoholic Beverages, NOT Otherwise Provided FOR; Preparation OR Treatment Thereof). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2018. By volume, Zezhi sits between Zeekit Online Shopping Ltd. and Zhejiang Feijian Technology Co., Ltd..

Zezhi's three-year grant acceleration

Zezhi Intellectual Property Service shows 1 grants in 2022–2024 against only 4 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.
