What this shows NOX's Innovation Score is 29.6/100 (31st 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 NOX?

Each dot is one of NOX’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). NOX’s own 4.8 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where NOX's grants concentrate

NOX Corporation is a focused PatentsView assignee: 10 CPC subclasses with 33.3% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2017 (7 grants) versus a trough of 1 in 2018. By volume, NOX sits between Noritake Itron Corporation and Nailomatic Ltd..

NOX's three-year grant acceleration

NOX Corporation shows 2 grants in 2022–2024 against only 2 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.
