What this shows Chun's Innovation Score is 38.2/100 (top 41% 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.

Where Chun's grants concentrate

Chun Nien Plastic Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 73.3% of grants classified under B25H (Workshop Equipment, e.g. FOR Marking-out WORK; Storage Means FOR Workshops). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2015. By volume, Chun sits between Chef'n Corporation and Coloright Ltd..

Chun's three-year grant acceleration

Chun Nien Plastic Ltd. shows 7 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.
