What this shows Zhejiang's Innovation Score is 63.4/100 (top 2% 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 Jinko Solar Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 88.5% of grants classified under H10F (Inorganic Semiconductor Devices Sensitive TO Infrared Radiation, Light, Electromagnetic Radiation OF Shorter Wavelength OR Corpuscular Radiation). Peak complete grant year is 2024 (59 grants) versus a trough of 1 in 2017. By volume, Zhejiang sits between National Chung Cheng University and Emerson Process Management Regulator Technologies, Inc..

Zhejiang's three-year grant acceleration

Zhejiang Jinko Solar Co., Ltd. shows 100 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.
