What this shows Nakanishi's Innovation Score is 30.5/100 (35th 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 Nakanishi?

Each dot is one of Nakanishi’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). Nakanishi’s own 4.7 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nakanishi's grants concentrate

Nakanishi Inc. is a focused PatentsView assignee: 16 CPC subclasses with 40.5% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2022. By volume, Nakanishi sits between Midwest Industries, Inc. and Nippon Thermostat Co., Ltd..

Nakanishi's three-year grant acceleration

Nakanishi Inc. shows 2 grants in 2022–2024 against only 14 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.
