Where Petroquip's grants concentrate

PetroQuip Energy Services, LLC is a focused PatentsView assignee: 2 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 2019 (2 grants) versus a trough of 1 in 2017. By volume, Petroquip sits between Perma Pure LLC and Phenomenome Discoveries Inc..

Petroquip's three-year grant acceleration

PetroQuip Energy Services, LLC shows 1 grants in 2022–2024 against only 5 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.
