Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Etherfax sits between Escape Therapeutics, Inc. and Exacta Systems, Llc.

Etherfax's three-year grant acceleration

Etherfax, Llc shows 3 grants in 2022–2024 against only 4 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.
