What this shows Mitsubishi's Innovation Score is 46.2/100 (top 21% 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 9.0 claims/patent is at or below the 14.8 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 Heavy Industries Marine Machinery & Equipment Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 84.6% of grants classified under F02B (Internal-combustion Piston ENGINES; Combustion Engines IN General). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2021. By volume, Mitsubishi sits between Mine ONE GmbH and Morphpackers Limited.

Mitsubishi's three-year grant acceleration

Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd. shows 11 grants in 2022–2024 against only 1 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.
