What this shows Nagano's Innovation Score is 41.7/100 (top 33% 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 Nagano?

Each dot is one of Nagano’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). Nagano’s own 13.6 claims/patent is at or below the 18.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nagano's grants concentrate

Nagano Automation Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 88.9% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2018. By volume, Nagano sits between Nuheart AS and NanoAL LLC.

Nagano's three-year grant acceleration

Nagano Automation Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
