What this shows Petroleum's Innovation Score is 36.9/100 (top 45% 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 Petroleum?

Each dot is one of Petroleum’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). Petroleum’s own 13.7 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Petroleum's grants concentrate

Petroleum Technology Company AS is a focused PatentsView assignee: 6 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 2016 (4 grants) versus a trough of 1 in 2023. By volume, Petroleum sits between Orthogonal, Inc. and Pitco Frialator, Inc..

Petroleum's three-year grant acceleration

Petroleum Technology Company AS shows 8 grants in 2022–2024 against only 6 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.
