Does more volume mean deeper claims for Rowan?

Each dot is one of Rowan’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). Rowan’s own 25.9 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rowan's grants concentrate

Rowan Holding, LLC is a focused PatentsView assignee: 21 CPC subclasses with 45.5% 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 (3 grants) versus a trough of 1 in 2017. By volume, Rowan sits between Rio Brands, LLC and S-oil Corporation.

Rowan's three-year grant acceleration

Rowan Holding, LLC shows 4 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.
