Where Ajax's grants concentrate

Ajax Tocco Magnethermic Corporation is a focused PatentsView assignee: 9 CPC subclasses with 57.1% of grants classified under C21D (Modifying THE Physical Structure OF Ferrous METALS; General Devices FOR Heat Treatment OF Ferrous OR Non-ferrous Metals OR ALLOYS; Making Metal Malleable, e.g. BY Decarburisation OR Tempering). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Ajax sits between Airbus DS Communications, Inc. and Aker Engineering & Technology AS.

Ajax's three-year grant acceleration

Ajax Tocco Magnethermic Corporation shows 1 grants in 2022–2024 against only 0 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.
