Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2018. By volume, Ellis sits between Elevator Safety Company and Emefcy Ltd..

Ellis's three-year grant acceleration

Ellis Patents (HOLDINGS) Limited shows 1 grants in 2022–2024 against only 1 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.
