Where Chengdu's grants concentrate

Chengdu Baiyu Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Chengdu sits between CheRay Co. Ltd. and Children's Hospital Medical Center of Akron.

Chengdu's three-year grant acceleration

Chengdu Baiyu Pharmaceutical Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
