Where Zhangjiagang's grants concentrate

Zhangjiagang SMK MFG. Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 10% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2024. By volume, Zhangjiagang sits between Zedsen Limited and Zimperium, Inc..

Zhangjiagang's three-year grant acceleration

Zhangjiagang SMK MFG. Co., Ltd. shows 1 grants in 2022–2024 against only 8 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.
