Does more volume mean deeper claims for Epiroc?
Each dot is one of Epiroc’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Epiroc’s own 15.8 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
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.
