What this shows Midori's Innovation Score is 40.2/100 (top 36% 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 Midori?

Each dot is one of Midori’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). Midori’s own 9.9 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Midori's grants concentrate

Midori Anzen Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 80% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Midori sits between Mersive Technologies, Inc. and Mixcomm, Inc..

Midori's three-year grant acceleration

Midori Anzen Co., Ltd. shows 4 grants in 2022–2024 against only 3 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.
