What this shows Mitsui's Innovation Score is 41.2/100 (top 34% 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 Mitsui?

Each dot is one of Mitsui’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). Mitsui’s own 14.0 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mitsui's grants concentrate

Mitsui Sugar Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 83.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). By volume, Mitsui sits between Mitralix Ltd. and Mobile Video Computing Solutions LLC.

Mitsui's three-year grant acceleration

Mitsui Sugar Co., Ltd. shows 2 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.
