JinkoSolar has initiated legal action against Longi, accusing the company of infringing on its proprietary TOPCon solar cell technology.
“JinkoSolar has demanded Longi cease infringing on the relevant patents and compensate for economic losses,” a company spokesperson told pv magazine.
The lawsuit, filed by JinkoSolar’s subsidiary Shangrao Xinyuan Motion Technology Development, was accepted by the Nanchang Intermediate People’s Court and is set for a hearing on February 13, 2025. The complaint alleges that Longi unlawfully utilized Jinko’s TOPCon and related photovoltaic module technologies.
Responding to inquiries, Longi stated that it has not received official legal documents concerning the case. “Longi prioritizes innovation and intellectual property protection,” said a company spokesperson, highlighting the firm’s extensive patent portfolio and commitment to respecting industry IP rights. Longi indicated it would investigate and potentially counterclaim regarding TOPCon and other technologies if necessary.
This follows JinkoSolar’s recent patent infringement lawsuit against VSUN, a subsidiary of Fujisolar, filed in the US District Court for the Northern District of California. JinkoSolar claims ownership of over 2,800 patents, including 462 related to n-type TOPCon technology, asserting its position as an industry leader in this field.
The outcomes of these cases could have significant implications for the solar sector, where innovation and patent disputes increasingly intersect.
