What this shows Nalux's Innovation Score is 40.9/100 (top 34% 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 Nalux?

Each dot is one of Nalux’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). Nalux’s own 8.9 claims/patent is at or below the 9.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nalux's grants concentrate

Nalux Co., Ltd. is a focused PatentsView assignee: 30 CPC subclasses with 89.5% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (11 grants) versus a trough of 1 in 2021. By volume, Nalux sits between Mikron Industries, Inc. and National Chain Company.

Nalux's three-year grant acceleration

Nalux Co., Ltd. shows 8 grants in 2022–2024 against only 15 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.
