What this shows Mitsubishi's Innovation Score is 44.5/100 (top 25% 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 Mitsubishi?

Each dot is one of Mitsubishi’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). Mitsubishi’s own 15.2 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mitsubishi's grants concentrate

Mitsubishi Electric US, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 78.9% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2018. By volume, Mitsubishi sits between Merck Canada Inc. and MycoWorks, Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Electric US, Inc. shows 12 grants in 2022–2024 against only 6 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.
