Does more volume mean deeper claims for Archer?

Each dot is one of Archer’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). Archer’s own 17.8 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Archer's grants concentrate

Archer Oiltools AS is a focused PatentsView assignee: 5 CPC subclasses with 100% 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 2023 (3 grants) versus a trough of 1 in 2016. By volume, Archer sits between API Healthcare Corporation and Armacell Enterprise GMBH & Co. KG.

Archer's three-year grant acceleration

Archer Oiltools AS shows 4 grants in 2022–2024 against only 1 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.
