What this shows Fourds's Innovation Score is 34.0/100 (46th 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 Fourds?

Each dot is one of Fourds’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). Fourds’s own 10.5 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fourds's grants concentrate

Fourds Limited is a focused PatentsView assignee: 3 CPC subclasses with 50% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Fourds sits between Forest Concepts, LLC and Freedom Solutions Group, LLC.

Fourds's three-year grant acceleration

Fourds Limited shows 4 grants in 2022–2024 against only 2 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.
