PVTIME – The United States Patent and Trademark Office’s Patent Trial and Appeal Board has issued a final ruling on a TOPCon solar cell patent dispute between US-based Maxeon Solar and Canadian Solar. The decision upholds Canadian Solar’s multiple claims of patent invalidity, declaring all the patents that Maxeon used to sue Canadian Solar in the US invalid.
Canadian Solar stated that this outcome marks another significant victory in its long-term efforts to address overseas intellectual property challenges and protect its achievements in independent innovation.
Byron Xu, the company’s Vice President of Legal Affairs, noted that the ruling reaffirms the dedication of Canadian Solar’s technical and legal teams to respecting and protecting the original intellectual property rights of both themselves and their industry peers. He added that the company actively defends itself against any patent infringement lawsuits lacking technical merit, emphasising that players in the photovoltaic industry should not use such patents to hinder technological progress.
To date, Canadian Solar has filed over 5,000 patent applications and secured more than 4,000 granted patents globally.
