Where emz-hanauer's grants concentrate

emz-Hanauer GmbH & Co. KGaA is a focused PatentsView assignee: 39 CPC subclasses with 50% of grants classified under D06F (Laundering, Drying, Ironing, Pressing OR Folding Textile Articles). Peak complete grant year is 2024 (15 grants) versus a trough of 2 in 2016. By volume, emz-hanauer sits between Vactronix Scientific, LLC and Academisch Ziekenhuis Leiden (H.O.D.N. LUMC) GMBH.

emz-hanauer's three-year grant acceleration

emz-Hanauer GmbH & Co. KGaA shows 26 grants in 2022–2024 against only 19 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.
