What this shows Mitsubishi's Innovation Score is 43.9/100 (top 27% 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 8.4 claims/patent is at or below the 16.1 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 Materials Electronic Chemicals Co., Ltd. is a focused PatentsView assignee: 40 CPC subclasses with 51.9% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2020. By volume, Mitsubishi sits between Micron Devices LLC and National Science Foundation.

Mitsubishi's three-year grant acceleration

Mitsubishi Materials Electronic Chemicals Co., Ltd. shows 6 grants in 2022–2024 against only 8 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.
