Where Yunnan's grants concentrate

Yunnan Huapu Quantum Material Co., Ltd is a focused PatentsView assignee: 13 CPC subclasses with 40% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Yunnan sits between Yonex Co., Ltd. and Yiwu Ledou Pet Products Co., Ltd..

Yunnan's three-year grant acceleration

Yunnan Huapu Quantum Material 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.
