What this shows Epiroc's Innovation Score is 23.0/100 (11th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

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 12.7 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Epiroc's grants concentrate

Epiroc Drilling Tools AB is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under E21D (SHAFTS; TUNNELS; GALLERIES; Large Underground Chambers). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2022. By volume, Epiroc sits between EON Reality, Inc. and Eskom Holdings SOC Limited.

Epiroc's three-year grant acceleration

Epiroc Drilling Tools AB shows 1 grants in 2022–2024 against only 6 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.
