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.
