Trina Solar Files Patent Infringement Lawsuit Against Canadian Solar Subsidiaries Over TOPCon Technology

Trina Solar Co., Ltd. a Chinese rival of Canadian Solar, has filed a patent infringement complaint in the U.S. District Court for the District of Delaware against three U.S. subsidiaries of Canadian Solar. The lawsuit claims that these subsidiaries are directly or indirectly infringing on two U.S. patents held by Trina related to tunnel oxide passivated contact (TOPCon) solar photovoltaic module technology.

As one of the largest solar product manufacturers globally, Canadian Solar produces and sells various solar products, including TOPCon solar modules, to customers in the United States and around the world. Canadian Solar has also filed and secured thousands of patents in multiple jurisdictions for solar cells and related technologies.”Canadian Solar respects and takes very seriously its own intellectual property rights and those of third parties. In our view, this is a frivolous lawsuit, and we expect the court will find that our proprietary TOPCon technology does not infringe on the patents claimed by Trina,” remarked Adam Walters, General Counsel, Americas for Canadian Solar’s Modules and Systems Solutions business.
