"We have a responsibility to protect our leadership position and we will continue to enforce our patent rights against those who attempt to sell infringing products in Europe and other markets,” he said.
Solar patent infringements are on the rise
Patent infringement in the photovoltaic energy market is becoming a recurring subject in Europe and the United States.
Em June 2024, in Europe, the solar energy manufacturer Maxeon Solar Technologies, based in Singapore, filed a patent infringement lawsuit against another company in the same segment, Aiko Solar.
A similar situation occurred in the Netherlands, which followed a process of solar cell patent infringement of further contact, which had been denied.
In the United States, within a month, the Maxeon Solar Technologies entered with various processes about alleged solar cell patent infringement TOPCon against manufacturers Hanwha Qcells, REC Solar and Canadian Solar.
