Where Mizuho's grants concentrate

Mizuho Corporation is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2017. By volume, Mizuho sits between Mission Infrared Electro Optics Technology Co., Ltd and Mobile Messenger Global, Inc..

Mizuho's three-year grant acceleration

Mizuho Corporation shows 5 grants in 2022–2024 against only 2 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.
