Where Neenah's grants concentrate

Neenah Foundry Company is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Neenah sits between Navipharm Co., Ltd. and Nestwave SAS.

Neenah's three-year grant acceleration

Neenah Foundry Company 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.
