Chengdu Yishouweisheng Technology Inc. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2019. By volume, Chengdu sits between ChemFree Corporation and Children's Medical Research Institute.
Chengdu Yishouweisheng Technology Inc. shows 3 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.
