Where Zahroof's grants concentrate

Zahroof Valves Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, Zahroof sits between Zrodelta, LLC and Zedel S.A..

Zahroof's three-year grant acceleration

Zahroof Valves Inc. shows 1 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.
