Settlement Ends Global Disputes
Solar giants LONGi Green Energy Technology and JinkoSolar Holding Co. have officially ended their global patent battles. The companies announced that they will withdraw all pending lawsuits and enter into a cross-licensing agreement.
The disputes stretched across China, the United States, Europe, Japan, and Australia. Both firms had filed multiple cases over solar cell technologies, creating uncertainty in the photovoltaic (PV) industry.
Focus on TOPCon and Back-Contact Technology
The disputes centered on TOPCon cells developed by JinkoSolar and Back-Contact (BC) technology promoted by LONGi.
- TOPCon (Tunnel Oxide Passivated Contact) improves efficiency by reducing electron loss.
- BC technology moves electrical contacts to the rear, removing shading from the front surface.
These advanced designs represent the future of solar cells. The settlement now allows both companies to freely advance their products without fear of injunctions.
Cross-Licensing of Core Patents
The companies confirmed that they will cross-license selected core patents. This move gives each firm freedom to use certain innovations owned by the other.
Details such as financial terms, duration, and exact patents remain undisclosed. However, the agreement covers the most important intellectual property for both technologies.
Industry Impact
The settlement signals a more stable IP environment for the solar industry. Costly legal disputes had slowed down innovation and threatened supply chains.
By resolving conflicts, LONGi and JinkoSolar can now focus on research, development, and faster commercialization. Industry experts believe the deal could also encourage other solar companies to settle disputes and cooperate on innovation.
Market Context
The PV industry faces falling module prices and oversupply challenges. Litigation added financial strain and created risks for investors.
Ending the disputes gives both firms stronger positions in global markets. It also boosts confidence among project developers and customers who rely on steady supply.
Strategic Takeaway
This agreement highlights how cross-licensing can replace litigation in high-tech industries. LONGi and JinkoSolar have chosen cooperation over conflict.
Their move may speed up adoption of next-generation solar modules and shape the competition around efficiency, cost, and scale rather than legal battles.
