What this shows Porta-fab's Innovation Score is 46.3/100 (top 21% 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 Porta-fab?

Each dot is one of Porta-fab’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). Porta-fab’s own 19.5 claims/patent is ABOVE the 17.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Porta-fab's grants concentrate

Porta-Fab Corporation is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under E04B (General Building CONSTRUCTIONS; Walls, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; Insulation OR Other Protection OF Buildings). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2021. By volume, Porta-fab sits between Polycontact AG and Precis, LLC.

Porta-fab's three-year grant acceleration

Porta-Fab Corporation shows 4 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.
