Where Marioff's grants concentrate

Marioff Corporation OY is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under A62C (Fire-fighting). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Marioff sits between M+C Schiffer GmbH and Merge Healthcare Solutions Inc..

Marioff's three-year grant acceleration

Marioff Corporation OY shows 9 grants in 2022–2024 against only 7 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.
