Does more volume mean deeper claims for Expro?
Each dot is one of Expro’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). Expro’s own 18.1 claims/patent is ABOVE the 18.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Expro's grants concentrate
Expro North SEA Limited is a focused PatentsView assignee: 20 CPC subclasses with 98.1% 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 2024 (11 grants) versus a trough of 1 in 2015. By volume, Expro sits between Debiotech S.A. and Gerresheimer Regensburg GmbH.
Expro's three-year grant acceleration
Expro North SEA Limited shows 20 grants in 2022–2024 against only 11 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.
