What this shows Stack's Innovation Score is 47.7/100 (top 18% 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 Stack?

Each dot is one of Stack’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). Stack’s own 18.6 claims/patent is ABOVE the 8.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stack's grants concentrate

Stack AV Co. is a focused PatentsView assignee: 7 CPC subclasses with 85.7% of grants classified under B60W (Conjoint Control OF Vehicle Sub-units OF Different Type OR Different FUNCTION; Control Systems Specially Adapted FOR Hybrid VEHICLES; Road Vehicle Drive Control Systems FOR Purposes NOT Related TO THE). By volume, Stack sits between Sri Lanka Institute of Nanotechnology (PVT) Ltd. and SteadyCare, LLC.

Stack's three-year grant acceleration

Stack AV Co. shows 5 grants in 2022–2024 against only 0 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.
