What this shows Zhuhai's Innovation Score is 37.9/100 (top 42% 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 Zhuhai's grants concentrate

Zhuhai Enpower Electric Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 87.5% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). By volume, Zhuhai sits between Zhejiang Xunshi Technology Co. Ltd and Zkteco USA LLC.

Zhuhai's three-year grant acceleration

Zhuhai Enpower Electric Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
