What this shows Interventek's Innovation Score is 28.8/100 (28th 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 Interventek?

Each dot is one of Interventek’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). Interventek’s own 24.3 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 Interventek's grants concentrate

Interventek Subsea Engineering Limited is a focused PatentsView assignee: 3 CPC subclasses with 83.3% 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 2019 (2 grants) versus a trough of 1 in 2021. By volume, Interventek sits between Intermountain Invention Management, LLC and Intrinsic Medical Imaging, LLC.

Interventek's three-year grant acceleration

Interventek Subsea Engineering Limited shows 1 grants in 2022–2024 against only 5 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.
