What this shows Mitsubishi's Innovation Score is 54.2/100 (top 8% 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 19.8 claims/patent is ABOVE the 17.5 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 Chemical UK Limited is a focused PatentsView assignee: 14 CPC subclasses with 61.5% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2023 (5 grants) versus a trough of 2 in 2021. By volume, Mitsubishi sits between Minerva Project, Inc. and Molecule Works Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Chemical UK Limited shows 10 grants in 2022–2024 against only 2 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.
