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 13.9 claims/patent is at or below the 16.8 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 Home Appliance Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 47.6% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2017. By volume, Mitsubishi sits between Miba Frictec GmbH and Municipal Parking Services, Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Electric Home Appliance Co., Ltd. shows 5 grants in 2022–2024 against only 15 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.
