What this shows Nsk-warner's Innovation Score is 28.1/100 (26th 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 Nsk-warner?

Each dot is one of Nsk-warner’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). Nsk-warner’s own 9.0 claims/patent is at or below the 11.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nsk-warner's grants concentrate

Nsk-warner K.K. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2021. By volume, Nsk-warner sits between National Agriculture AND Food Research Organization and Neurohabilitation Corporation.

Nsk-warner's three-year grant acceleration

Nsk-warner K.K. shows 3 grants in 2022–2024 against only 9 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.
