What this shows Zhejiang's Innovation Score is 45.4/100 (top 23% 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 Zhejiang's grants concentrate

Zhejiang YAT Electrical Appliance Co., Ltd is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Zhejiang sits between Zhejiang JIU Kang Electric Appliances Co., Ltd. and Zipstring LLC.

Zhejiang's three-year grant acceleration

Zhejiang YAT Electrical Appliance Co., Ltd shows 5 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.
