Where Herzog's grants concentrate

Herzog Railroad Services, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 72.2% of grants classified under E01B (Permanent WAY; Permanent-way TOOLS; Machines FOR Making Railways OF ALL Kinds). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Herzog sits between Halo Microelectronics Co., Ltd. and Hydragraphix LLC.

Herzog's three-year grant acceleration

Herzog Railroad Services, Inc. shows 5 grants in 2022–2024 against only 1 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.
