What this shows Stanadyne's Innovation Score is 34.1/100 (47th 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 Stanadyne?

Each dot is one of Stanadyne’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). Stanadyne’s own 13.1 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stanadyne's grants concentrate

Stanadyne LLC is a focused PatentsView assignee: 12 CPC subclasses with 95.2% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2018. By volume, Stanadyne sits between SpecGX LLC and Strato, Inc..

Stanadyne's three-year grant acceleration

Stanadyne LLC shows 4 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.
