What this shows Soilmec's Innovation Score is 44.8/100 (top 25% 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 Soilmec?

Each dot is one of Soilmec’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). Soilmec’s own 14.8 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Soilmec's grants concentrate

Soilmec S.P.A. is a focused PatentsView assignee: 24 CPC subclasses with 63.3% 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 2015 (8 grants) versus a trough of 1 in 2021. By volume, Soilmec sits between Siemens Ltd., China and Suven Life Sciences Limited.

Soilmec's three-year grant acceleration

Soilmec S.P.A. shows 7 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.
