What this shows Extang's Innovation Score is 59.7/100 (top 4% 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 Extang?

Each dot is one of Extang’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). Extang’s own 16.2 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
