JinkoSolar has taken its patent infringement fight against LONGi to Australia
The Federal Court of Australia has accepted the petition filed by JinkoSolar
The court has set the first hearing in the case for February 21, 2025
The patent infringement dispute between leading Chinese solar PV manufacturers JinkoSolar and LONGi is nowhere near an end. In fact, its geographical purview is expanding with JinkoSolar initiating legal action against its compatriot in Australia.
According to a notice published by the Federal Court of Australia, JinkoSolar subsidiaries namely Jinko Solar Australia Holdings Pty Ltd, Shanghai Jinko Green Energy Management Co Ltd, and Zhejiang Jinko Solar Co Ltd have filed a lawsuit against LONGi Solar Australia Pty Ltd.
JinkoSolar filed the case on February 4, 2025. It has been accepted by the Federal Court of Australia. The first hearing has been scheduled by the court for February 21, 2025.
This follows JinkoSolar’s previous legal action against LONGi filed in January 2025 in China regarding intellectual property (IP) claims related to TOPCon. Later, it took the fight to Japan (see JinkoSolar Takes LONGi Patent Fight To Japan).
The details of the Australian lawsuit aren’t clear at this time, but it is likely centered around JinkoSolar’s patent technologies for the design and manufacturing of high-efficiency solar cells and modules.
An early adopter of TOPCon solar cell technology, JinkoSolar touts over 2,800 issued patents to its name, including a proprietary portfolio that includes 462 industry-leading patents related to n-type TOPCon technology. It has previously stated that the manufacturer will resort to legal action to address any acts of infringement of its IP.
JinkoSolar previously also launched patent infringement lawsuits against VSUN Solar USA and TOYO Solar in the US (see JinkoSolar Files Patent Infringements Case Against VSUN & TOYO).
There has been no official word from LONGi so far on the JinkoSolar legal action. LONGi had previously been embroiled in patent lawsuits filed by South Korea’s Hanwha Solutions in various markets. The duo reached a patent cross-licensing agreement in May 2023 under which they both established that they have the rights to use the relevant patents globally (see Patent Infringement Dispute Settled).
