Does more volume mean deeper claims for Subsea?

Each dot is one of Subsea’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). Subsea’s own 23.6 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Subsea's grants concentrate

Subsea 7 Norway AS is a focused PatentsView assignee: 27 CPC subclasses with 54.3% 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 2021 (7 grants) versus a trough of 1 in 2016. By volume, Subsea sits between Showa Glove Co. and Shandong University of Technology.

Subsea's three-year grant acceleration

Subsea 7 Norway AS shows 17 grants in 2022–2024 against only 11 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.
