Where Permavoid's grants concentrate

Permavoid Limited is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under E01C (Construction OF, OR Surfaces FOR, Roads, Sports Grounds, OR THE LIKE; Machines OR Auxiliary Tools FOR Construction OR Repair). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Permavoid sits between Performance AND Privacy Ireland Ltd. and PFG IP LLC.

Permavoid's three-year grant acceleration

Permavoid Limited shows 1 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.
