What this shows Itoki's Innovation Score is 20.9/100 (8th percentile 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 Itoki?

Each dot is one of Itoki’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). Itoki’s own 1.8 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Itoki's grants concentrate

Itoki Corporation is a focused PatentsView assignee: 1 CPC subclasses with 9.5% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2019. By volume, Itoki sits between Inotera Memories, Inc. and Kokuyo Co., Ltd..

Itoki's three-year grant acceleration

Itoki Corporation shows 4 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.
