What this shows Prostar's Innovation Score is 24.3/100 (14th 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 Prostar?

Each dot is one of Prostar’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). Prostar’s own 13.7 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Prostar's grants concentrate

Prostar Energy Technologies (USA) LLC is a focused PatentsView assignee: 3 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 2019 (3 grants) versus a trough of 2 in 2021. By volume, Prostar sits between ProNova Solutions, LLC and Pujiang Sansi Optoelectronic Technology Co. Ltd..

Prostar's three-year grant acceleration

Prostar Energy Technologies (USA) LLC shows 2 grants in 2022–2024 against only 8 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.
