Where ZFX's grants concentrate

ZFX GMBH is a focused PatentsView assignee: 7 CPC subclasses with 75% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, ZFX sits between Zeku Technology (SHANGHAI) Corp., Ltd. and Zhejiang Jingyi NEW Material Technology Co. Ltd.

ZFX's three-year grant acceleration

ZFX GMBH shows 1 grants in 2022–2024 against only 4 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.
