Where Nemak's grants concentrate

Nemak, S.A.B. de C.V. is a focused PatentsView assignee: 20 CPC subclasses with 50% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2017. By volume, Nemak sits between Nanchang Hangkong University and Ningbo Shijia Cleaning Tools Co., Ltd..

Nemak's three-year grant acceleration

Nemak, S.A.B. de C.V. shows 5 grants in 2022–2024 against only 10 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.
