First Solar Sues JinkoSolar, Canadian Solar, and Mundra Solar for Patent Infringement

First Solar Inc. is pursuing litigation against JinkoSolar, Canadian Solar, and Mundra Solar, alleging infringement of its Tunnel Oxide Passivated Contact (TOPCon) patents in the United States District Court for the District of Delaware. The company’s litigation follows the US Patent and Trademark Office’s rejection of three separate attempts by the rival solar manufacturers to challenge the validity of First Solar’s TOPCon patents through Inter Partes Review applications. First Solar’s patents, which cover methods for manufacturing TOPCon crystalline silicon photovoltaic solar cells, remain in force with validity extending to 2030 and beyond. The company has stated its intention to continue enforcing and licensing its TOPCon technology patent portfolio both in the US and internationally.
