Where Chundo's grants concentrate

Chundo Pharm Co., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2023. By volume, Chundo sits between Christopher Designs, Inc. and Cimc Enric Investment Holdings (SHENZHEN) Co., Ltd..

Chundo's three-year grant acceleration

Chundo Pharm Co., Ltd shows 5 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.
