Where Keller's grants concentrate

Keller Holding GmbH is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Keller sits between Katana Racing, Inc. and Keystone Ridge Designs, Inc..

Keller's three-year grant acceleration

Keller Holding GmbH shows 2 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.
