What this shows Maersk's Innovation Score is 45.0/100 (top 24% 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 Maersk?

Each dot is one of Maersk’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). Maersk’s own 22.1 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Maersk's grants concentrate

Maersk Drilling A/S is a focused PatentsView assignee: 19 CPC subclasses with 85.7% 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 2022 (10 grants) versus a trough of 1 in 2018. By volume, Maersk sits between Longsand Limited and Mitsubishi Heavy Industries Automotive Thermal Systems, Ltd..

Maersk's three-year grant acceleration

Maersk Drilling A/S shows 10 grants in 2022–2024 against only 17 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.
