What this shows Carrier's Innovation Score is 46.9/100 (top 20% 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 Carrier?

Each dot is one of Carrier’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). Carrier’s own 6.8 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Carrier's grants concentrate

Carrier Japan Corporation is a focused PatentsView assignee: 12 CPC subclasses with 55% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). By volume, Carrier sits between Canfield Scientific, Incorporated and Chemistry Design Werks, LLC.

Carrier's three-year grant acceleration

Carrier Japan Corporation shows 3 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.
