What this shows Whisper's Innovation Score is 45.5/100 (top 23% 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 Whisper?

Each dot is one of Whisper’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). Whisper’s own 10.0 claims/patent is ABOVE the 8.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Whisper's grants concentrate

Whisper Aero Inc. is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under B64D (Equipment FOR Fitting IN OR TO AIRCRAFT; Flight SUITS; PARACHUTES; Arrangement OR Mounting OF Power Plants OR Propulsion Transmissions IN Aircraft). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2023. By volume, Whisper sits between Washington University in St. Louis and Wiesman Holdings, LLC.

Whisper's three-year grant acceleration

Whisper Aero Inc. shows 4 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.
