Maxeon (MAXN) Initiates TOPCon Patent Infringement Lawsuit

Maxeon Solar Technologies, Ltd. (NASDAQ: MAXN), a global leader in solar innovation and channels, today announced that it has initiated a patent infringement lawsuit in the Eastern District of Texas against Canadian Solar, Inc., alleging infringement of Maxeon patents relating to TOPCon (Tunnel Oxide Passivated Contact) solar cell technology.

The innovations behind Maxeon IBC, Shingled Hypercell, and TOPCon technologies are protected by a global patent portfolio of over 1,650 granted patents and over 330 pending patent applications.

"Maxeon has a strong heritage in developing solar cell technology, leading the development and commercialization of tunnel oxide passivated contacts," said Marc Robinson, Associate General Counsel at Maxeon. "Years before the moniker 'TOPCon' started to be used in the industry to describe a tunnel oxide passivated contact-based solar cell, our scientists and engineers had developed several ways to implement TOPCon technology into both back contact and front contact solar cells. Maxeon has many patents related to TOPCon technology, with inventions drawn to fundamental TOPCon solar cell architectures dating back to the 2000s. This is Maxeon's first action to enforce its valuable patent rights in the United States, and Maxeon will continue to vigorously enforce its patent rights in the United States and its other markets."
