What this shows Mitsubishi's Innovation Score is 40.0/100 (top 37% 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 10.2 claims/patent is ABOVE the 9.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Mitsubishi's grants concentrate

Mitsubishi Corporation is a focused PatentsView assignee: 27 CPC subclasses with 41.7% of grants classified under C10M (Lubricating Compositions ; USE OF Chemical Substances Either Alone OR AS Lubricating Ingredients IN A Lubricating Composition). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, Mitsubishi sits between Ming Chuan University and Miworld Accessories LLC.

Mitsubishi's three-year grant acceleration

Mitsubishi Corporation shows 3 grants in 2022–2024 against only 3 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.
