Where Flexidrill's grants concentrate

Flexidrill Limited is a focused PatentsView assignee: 1 CPC subclasses with 80% 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 2016 (3 grants) versus a trough of 1 in 2017. By volume, Flexidrill sits between Fischer Sports Gmbh and FMC Separation Systems, BV.

Flexidrill's three-year grant acceleration

Flexidrill Limited shows 3 grants in 2022–2024 against only 3 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.
