What this shows Permavoid's Innovation Score is 32.5/100 (42nd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Permavoid?

Each dot is one of Permavoid’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Permavoid’s own 20.9 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
