Does more volume mean deeper claims for Black?

Each dot is one of Black’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). Black’s own 35.3 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Black's grants concentrate

Black Diamond Oilfield Rentals LLC is a focused PatentsView assignee: 9 CPC subclasses with 92.6% 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 (9 grants) versus a trough of 4 in 2024. By volume, Black sits between Bausch + Lomb Ireland Limited and Brusa Elektronik AG.

Black's three-year grant acceleration

Black Diamond Oilfield Rentals LLC shows 19 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.
