Does more volume mean deeper claims for Stream-flo?

Each dot is one of Stream-flo’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). Stream-flo’s own 30.1 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stream-flo's grants concentrate

Stream-Flo Industries Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 87.5% 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 2018 (2 grants) versus a trough of 1 in 2015. By volume, Stream-flo sits between Stodge Inc. and Sud Scrub Inc..

Stream-flo's three-year grant acceleration

Stream-Flo Industries Ltd. shows 1 grants in 2022–2024 against only 3 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.
