Portfolio overview
ZHEJIANG JINKO SOLAR CO., LTD. has been granted 156 US utility patents between 2017 and 2025, placing ZHEJIANG JINKO SOLAR CO., LTD. at rank #2,508 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in H10F (INORGANIC SEMICONDUCTOR DEVICES SENSITIVE TO INFRARED RADIATION, LIGHT, ELECTROMAGNETIC RADIATION OF SHORTER WAVELENGTH OR CORPUSCULAR RADIATION). As a Foreign Corporation, ZHEJIANG JINKO SOLAR CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 63.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 155 grants, compared with 1 in the 2015–2019 window — a +15400% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. ZHEJIANG JINKO SOLAR CO., LTD.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZHEJIANG JINKO SOLAR CO., LTD. against peers pursuing similar technology classes.
