Maxeon Solar Technologies files lawsuit for TOPCon patent infringement

In a recent development, Maxeon Solar Technologies has filed a patent infringement lawsuit against Canadian Solar in the Eastern District of Texas. The lawsuit accuses Canadian Solar of violating Maxeon’s patents related to its tunnel oxide passivated contact (TOPCon) solar cell technology.

Maxeon claims that its innovations are protected by a global patent portfolio and that it has been at the forefront of developing and commercializing TOPCon technology for many years. According to Marc Robinson, associate general counsel at Maxeon, the company’s scientists and engineers were working on implementing TOPCon technology into both back contact and front contact solar cells years before the term “TOPCon” became widely used in the industry. Maxeon holds numerous patents related to TOPCon technology, some of which date back to the early 2000s.

This marks Maxeon’s first effort to enforce its patent rights in the United States, and the company plans to continue vigorously protecting its patents in the US and other markets.
