What this shows SDG's Innovation Score is 43.8/100 (top 27% 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 SDG?

Each dot is one of SDG’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). SDG’s own 19.0 claims/patent is ABOVE the 6.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where SDG's grants concentrate

SDG, LLC is a focused PatentsView assignee: 17 CPC subclasses with 55.9% 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 2015 (6 grants) versus a trough of 1 in 2017. By volume, SDG sits between Rock Solid Industries International (Pty) Ltd and Sophia & William Brands Co. Ltd.

SDG's three-year grant acceleration

SDG, LLC shows 10 grants in 2022–2024 against only 12 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.
