What this shows NZ's Innovation Score is 30.9/100 (36th 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 NZ?

Each dot is one of NZ’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). NZ’s own 5.1 claims/patent is at or below the 17.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where NZ's grants concentrate

NZ Tube Mills Limited is a focused PatentsView assignee: 3 CPC subclasses with 31.3% of grants classified under A01G (HORTICULTURE; Cultivation OF Vegetables, Flowers, Rice, Fruit, Vines, Hops OR SEAWEED; FORESTRY; Watering). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2021. By volume, NZ sits between Nsfocus Information Technology Co., Ltd. and Nectar, Inc..

NZ's three-year grant acceleration

NZ Tube Mills Limited shows 9 grants in 2022–2024 against only 5 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.
