Singapore-based solar manufacturer Maxeon Solar Technologies and Chinese solar cell and module manufacturer Aiko Solar have announced a global settlement that resolves all pending patent disputes between the two companies.
“Under the agreement, Aiko will license all of Maxeon’s back-contact (BC) solar cell and module patents outside the United States, including both existing patents and patents that will be newly added over the next five years,” the joint statement read. “Also pursuant to the agreement, Maxeon has agreed to fully withdraw and terminate all pending and potential patent enforcement actions against Aiko, and Aiko has agreed to withdraw and terminate all invalidation efforts against Maxeon’s patents.”
No further details of the settlement have been released.
Maxeon initiated the lawsuit against Aiko in 2023, when it filed a complaint with the Mannheim Regional Court for infringement of Maxeon’s patent EP2297788. In May 2025, the District Court of The Hague rejected a request for interim injunction that Maxeon had filed against Aiko in connection with the patent. The same court rejected Maxeon’s initial injunction request in May 2024, prompting the company to immediately appeal.
In June 2024, Maxeon initiated a second lawsuit against Aiko and several of its partners at the Unified Patent Court Local Division in Düsseldorf, claiming infringement of Maxeon’s patent EP3065184.
In December 2025, Maxeon filed a new patent infringement lawsuit against Aiko at the Regional Court of Munich I in Germany. This lawsuit alleged that Aiko and its European distribution network had infringed Maxeon’s core BC solar technology patent EP2297789B1 in Aiko’s “second and third generation” BC solar panel products, which are sold in the European market.
