What this shows Ensco's Innovation Score is 33.7/100 (45th percentile 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 Ensco?

Each dot is one of Ensco’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). Ensco’s own 18.6 claims/patent is ABOVE the 16.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ensco's grants concentrate

Ensco International Incorporated is a focused PatentsView assignee: 8 CPC subclasses with 88.5% 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 2018 (7 grants) versus a trough of 1 in 2022. By volume, Ensco sits between Elopak AS and Fabbrica D'armi Pietro Beretta S.P.A..

Ensco's three-year grant acceleration

Ensco International Incorporated shows 2 grants in 2022–2024 against only 12 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.
