What this shows Mitsubishi's Innovation Score is 47.6/100 (top 18% 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 10.8 claims/patent is at or below the 12.3 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 Engineering Company, Limited is a focused PatentsView assignee: 25 CPC subclasses with 47.5% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2018 (13 grants) versus a trough of 2 in 2021. By volume, Mitsubishi sits between M&R Printing Equipment, Inc. and Machine Zone Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Electric Engineering Company, Limited shows 8 grants in 2022–2024 against only 5 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.
