Canadian Solar Comments on Complaint Filed by Maxeon Solar

PVTIME – On 28 March 2024, Canadian Solar Inc. (Canadian Solar, NASDAQ: CSIQ), issued its comment on complaint filed by Maxeon Solar.

Canadian Solar recently became aware that Maxeon Solar Pte. Ltd. (“Maxeon”) has filed a patent infringement lawsuit against Canadian Solar, Inc. in the U.S. District Court in the Eastern District of Texas, entitled Maxeon Solar Pte. Ltd. v. Canadian Solar, Inc., Civil Action No. 2:24-cv-210 (E.D. Tex.). The suit alleges that Canadian Solar, Inc., via its affiliates, is directly or indirectly infringing on three patents now held by Maxeon relating to tunnel oxide passivated contact solar photovoltaic module technology (commonly referred to in the solar industry as “TOPCon” technology).

As one of the largest solar product manufacturers in the world, Canadian Solar manufactures and sells many different types of solar products, both in the United States and elsewhere in the world, including TOPCon solar modules. As a technology company, Canadian Solar respects and takes very seriously its own intellectual property rights and those of third parties. Canadian Solar has itself filed and received thousands of patents in various jurisdictions for solar cells and related technology.

Although Canadian Solar is continuing to consult its lawyers and study Maxeon’s complaint, the Company’s preliminary assessment is that the claims in the complaint are entirely without merit. Canadian Solar denies that its TOPCon technology infringes on Maxeon’s patents and intends to vigorously defend itself against Maxeon’s claims. Canadian Solar is confident that its TOPCon technology and processes will be vindicated in court at the appropriate time. Meanwhile, Canadian Solar will continue to sell high quality solar products in the United States and elsewhere, as it has done since its founding in Canada more than 20 years ago.

Maxeon Solar Technologies Initiates TOPCon Patent Infringement Lawsuit

On 25 March 2024, Maxeon Solar Technologies, Ltd. (NASDAQ:MAXN), a global leader in solar innovation and channels, 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.”
