What this shows Nagano's Innovation Score is 36.2/100 (top 47% 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 6.3 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 Nagano's grants concentrate

Nagano Keiki Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 93.8% of grants classified under G01L (Measuring Force, Stress, Torque, Work, Mechanical Power, Mechanical Efficiency, OR Fluid Pressure). Peak complete grant year is 2017 (8 grants) versus a trough of 2 in 2016. By volume, Nagano sits between McCue Corporation and Nippon Zoki Pharmaceutical Co., Ltd..

Nagano's three-year grant acceleration

Nagano Keiki 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.
