What this shows Mitsubishi's Innovation Score is 35.3/100 (top 50% 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 9.2 claims/patent is at or below the 10.5 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 Chemical Engineering Corporation is a focused PatentsView assignee: 19 CPC subclasses with 33.3% of grants classified under B01D (Separation). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, Mitsubishi sits between Millipede, Inc. and Mitsubishi Shipbuilding Co., Ltd..

Mitsubishi's three-year grant acceleration

Mitsubishi Chemical Engineering Corporation shows 5 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.
