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.
