Trina Solar Initiates Legal Action to Enforce TOPCon Technology Patents

Trina’s complaint requests that the ITC issue a limited exclusion order and cease-and-desist orders against Runergy and Adani to bar the importation into the United States of certain solar cells, modules, panels, components thereof, and products containing the same that infringe Trina’s patents.

Trinasolar, a global leader in smart solar products and solutions, today announced it filed a complaint with the U.S. International Trade Commission (ITC) to prevent Runergy and Adani Green Energy Ltd from improperly importing and selling products that infringe two Trina patents relating to TOPCon (Tunnel Oxide Passivated Contact) solar cell technology.


"Protecting the integrity of Trina's TOPCon technology is critical," said Steven Zhu, president of Trinasolar US. "We are committed to defending our innovations and will take decisive action against any infringement on our intellectual property."

Trina's complaint requests that the ITC issue a limited exclusion order and cease-and-desist orders against Runergy and Adani to bar the importation into the United States of certain solar cells, modules, panels, components thereof, and products containing the same that infringe Trina's patents. Trina currently has separate patent infringement suits relating to TOPCon technology pending against Runergy in the District of Delaware and the Central District of California.

Trina owns over 2000 patents, including a significant number of core TOPCon technology patents, in addition to PERC and Heterojunction (HJT) patents. The patents protect Trina's IP rights to critical N-type TOPCon technology used in solar module production and strengthen Trina's position as the market leader in providing TOPCon products for customers. Trina is actively reviewing possible patent infringement by other manufacturers supplying the U.S. market.

"We are proud of our extensive patent portfolio and invite collaboration with U.S. partners who adhere to proper protocols for utilizing our patented technology," said Zhu. "Our technological innovations and intellectual property, along with Trina's fully compliant supply chain, are crucial for driving the success of solar manufacturing in the U.S."

More information on Trina Solar's cell and module patents can be found on the United States Patent and Trademark Office (USPTO) and the World Intellectual Property (WIPO) websites.
