Where Epiroc's grants concentrate

Epiroc Drilling Tools Aktiebolag is a focused PatentsView assignee: 12 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 2018 (3 grants) versus a trough of 1 in 2019. By volume, Epiroc sits between Encompass Group, Llc. and ES Fibervisions Hong Kong Limited.

Epiroc's three-year grant acceleration

Epiroc Drilling Tools Aktiebolag shows 2 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.
