Singapore-headquartered Maxeon Solar Technologies has launched yet another patent infringement lawsuit in the Eastern District of Texas, US, this time against Hanwha Qcells for its TOPCon related patents.

According to its website, Hanwha Qcells has the ‘biggest’ market share in the major markets including Germany, the UK, South Korea and Japan. In the US, it operates 5.1 GW of solar module production capacity in Georgia and plans to expand vertically to a total of 8.4 GW by 2024 through its local solar manufacturing arm Qcells North America.

TaiyangNews has reached out to Hanwha Qcells for its comment on the lawsuit.

The lawsuit against Hanwha comes just days after Maxeon announced similar lawsuits regarding its TOPCon patents against Norway’s REC Solar Holdings and Canadian Solar (see REC Solar Holdings Accused Of TOPCon Patent Infringement).

“In November 2023, Maxeon initiated a TOPCon patent infringement investigation in the United States, and this lawsuit against Hanwha Q CELLS, along with recent similar actions against Canadian Solar, Inc. and REC Solar Holdings AS, are results of that investigation,” said Maxeon’s Associate General Counsel, Marc Robinson.

While Maxeon did not share any details of the lawsuit, it says the company is exercising its responsibility to protect the leadership position it has earned from its substantial R&D investments.

Robinson added that the company will ‘continue to enforce its patent rights against those who are attempting to sell infringing products in the US and its other markets.’
