What this shows Nan's Innovation Score is 35.0/100 (top 50% 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 Nan?

Each dot is one of Nan’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). Nan’s own 6.2 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nan's grants concentrate

Nan Juen International Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 72.7% of grants classified under A47B (TABLES; DESKS; Office FURNITURE; CABINETS; DRAWERS; General Details OF Furniture). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2020. By volume, Nan sits between Nippon Steel Engineering Co., Ltd and New York Stem Cell Foundation, Inc..

Nan's three-year grant acceleration

Nan Juen International Co., Ltd. shows 5 grants in 2022–2024 against only 3 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.
