What this shows Nakanishi's Innovation Score is 42.9/100 (top 30% 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 5.7 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 Metal Works Co., Ltd. is a focused PatentsView assignee: 35 CPC subclasses with 58.3% of grants classified under F16C (SHAFTS; Flexible SHAFTS; Elements OR Crankshaft MECHANISMS; Rotary Bodies Other Than Gearing ELEMENTS; Bearings). Peak complete grant year is 2020 (7 grants) versus a trough of 2 in 2015. By volume, Nakanishi sits between Mips Tech, LLC and Noblis, Inc..

Nakanishi's three-year grant acceleration

Nakanishi Metal Works Co., Ltd. shows 13 grants in 2022–2024 against only 17 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.
