Does more volume mean deeper claims for Dust?

Each dot is one of Dust’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). Dust’s own 20.2 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dust's grants concentrate

Dust Free, LP is a focused PatentsView assignee: 8 CPC subclasses with 55.6% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2020. By volume, Dust sits between DroneDeploy, Inc. and Eagle Outdoor Camping Products Co., Ltd..

Dust's three-year grant acceleration

Dust Free, LP shows 1 grants in 2022–2024 against only 1 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.
