What this shows Mitsui's Innovation Score is 51.2/100 (top 12% 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 11.6 claims/patent is at or below the 14.6 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 Chemicals Tohcello, Inc. is a focused PatentsView assignee: 34 CPC subclasses with 56.1% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (10 grants) versus a trough of 3 in 2015. By volume, Mitsui sits between Mastercard Technologies Canada ULC and North Atlantic Imports, LLC.

Mitsui's three-year grant acceleration

Mitsui Chemicals Tohcello, Inc. shows 23 grants in 2022–2024 against only 16 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.
