What this shows Itoh's Innovation Score is 34.6/100 (48th 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 Itoh?

Each dot is one of Itoh’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). Itoh’s own 16.3 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Itoh's grants concentrate

Itoh Denki Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 96.8% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2015. By volume, Itoh sits between Industrial Scientific Corporation and JSR Life Sciences, LLC.

Itoh's three-year grant acceleration

Itoh Denki Co., Ltd. shows 3 grants in 2022–2024 against only 12 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.
