Maxeon Solar has filed a patent infringement lawsuit against Canadian Solar in the Eastern District of Texas, alleging that Canadian Solar has infringed on Maxeon’s TOPCon patents. Maxeon, which acquired Solaria’s shingled-cell technology patents last year, now holds over 1,650 granted patents and over 330 pending patent applications related to solar technology.
According to Marc Robinson, Associate General Counsel at Maxeon, the company has a strong history in developing solar cell technology, including tunnel oxide passivated contacts (TOPCon). Maxeon has many patents related to TOPCon technology dating back to the 2000s and is prepared to enforce its patent rights in the United States and other markets.
Maxeon’s lawsuit against Canadian Solar alleges infringement on three patents: the ‘516 patent, the ‘053 patent, and the ‘315 patent, which were all originally granted to SunPower and later assigned to Maxeon. Canadian Solar has not yet responded to the lawsuit.
This is not the first time Canadian Solar has faced a patent infringement lawsuit. In 2020, Solaria filed a similar lawsuit against Canadian Solar, claiming that Canadian Solar had stolen Solaria’s patents for shingled solar modules. The International Trade Commission ruled in favor of Solaria, and Canadian Solar agreed not to sell shingled solar panels in the United States for seven years.
