Does more volume mean deeper claims for Weatherford?

Each dot is one of Weatherford’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). Weatherford’s own 19.5 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Weatherford's grants concentrate

Weatherford U.K. Limited is a focused PatentsView assignee: 9 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 2020 (7 grants) versus a trough of 1 in 2015. By volume, Weatherford sits between Vyaire Medical, Inc. and X One, Inc..

Weatherford's three-year grant acceleration

Weatherford U.K. Limited shows 12 grants in 2022–2024 against only 16 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.
