Where Fluidmaster's grants concentrate

Fluidmaster, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 75% of grants classified under E03D (Water-closets OR Urinals With Flushing DEVICES; Flushing Valves Therefor). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2015. By volume, Fluidmaster sits between Equal1.Labs Inc. and FireEye Security Holdings US LLC.

Fluidmaster's three-year grant acceleration

Fluidmaster, Inc. shows 10 grants in 2022–2024 against only 12 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.
