Where Epiroc's grants concentrate

Epiroc Rock Drills Aktiebolag is a focused PatentsView assignee: 30 CPC subclasses with 71.4% 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 (11 grants) versus a trough of 1 in 2021. By volume, Epiroc sits between DET International Holding Limited and Electrolux do Brasil S.A..

Epiroc's three-year grant acceleration

Epiroc Rock Drills Aktiebolag shows 12 grants in 2022–2024 against only 12 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.
