Does more volume mean deeper claims for Captive-aire?

Each dot is one of Captive-aire’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). Captive-aire’s own 10.3 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Captive-aire's grants concentrate

Captive-Aire Systems, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2022 (4 grants) versus a trough of 2 in 2021. By volume, Captive-aire sits between Capewell Aerial Systems LLC and Carbonics Inc..

Captive-aire's three-year grant acceleration

Captive-Aire Systems, Inc. shows 4 grants in 2022–2024 against only 2 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.
