What this shows Fourphase's Innovation Score is 31.3/100 (37th 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 Fourphase?

Each dot is one of Fourphase’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). Fourphase’s own 22.7 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Fourphase's grants concentrate

Fourphase AS is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Fourphase sits between Fortress Stabilization Systems and Freedom Surveillance, LLC.

Fourphase's three-year grant acceleration

Fourphase AS 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.
