Where Drillform's grants concentrate

Drillform Technical Services Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 90.9% 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 (3 grants) versus a trough of 1 in 2021. By volume, Drillform sits between Dornbracht Ag & Co. KG and Dezurik, Inc..

Drillform's three-year grant acceleration

Drillform Technical Services Ltd. shows 3 grants in 2022–2024 against only 7 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.
