Where Extang's grants concentrate

Extang Corporation is a focused PatentsView assignee: 18 CPC subclasses with 80.3% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2023 (18 grants) versus a trough of 2 in 2016. By volume, Extang sits between DMF, Inc. and Hydro-Quebec.

Extang's three-year grant acceleration

Extang Corporation shows 39 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.
