What this shows Sturman's Innovation Score is 36.5/100 (top 46% 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 Sturman?

Each dot is one of Sturman’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). Sturman’s own 22.0 claims/patent is ABOVE the 18.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sturman's grants concentrate

Sturman Digital Systems, LLC is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under F02B (Internal-combustion Piston ENGINES; Combustion Engines IN General). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Sturman sits between States Title, LLC and Superb AI Co., Ltd..

Sturman's three-year grant acceleration

Sturman Digital Systems, LLC shows 2 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.
