What this shows Evolution's Innovation Score is 38.6/100 (top 40% 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 Evolution?

Each dot is one of Evolution’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). Evolution’s own 10.0 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Evolution's grants concentrate

Evolution Oil Tools Inc. is a focused PatentsView assignee: 2 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 2023 (2 grants) versus a trough of 1 in 2016. By volume, Evolution sits between Eugen Seitz AG and Expro Americas, LLC.

Evolution's three-year grant acceleration

Evolution Oil Tools Inc. shows 4 grants in 2022–2024 against only 0 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.
