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 15.5 claims/patent is ABOVE the 10.2 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 Generator Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under H02K (Dynamo-electric Machines). By volume, Mitsubishi sits between Minkpapir A/S and MMT, Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Generator Co., Ltd. shows 3 grants in 2022–2024 against only 0 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.
