Does more volume mean deeper claims for Nittoku?

Each dot is one of Nittoku’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). Nittoku’s own 6.9 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nittoku's grants concentrate

Nittoku Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 37.5% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2022. By volume, Nittoku sits between Nikon-essilor Co., Ltd. and Nsfocus Information Technology Co., Ltd..

Nittoku's three-year grant acceleration

Nittoku Co., Ltd. shows 8 grants in 2022–2024 against only 7 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.
