New York, 26 August 2022 (dpa/MIA) — US biotech company Moderna has accused German rival BioNTech - and its partner during the pandemic, pharmaceutical giant Pfizer - of patent infringements in the development of vaccines against the coronavirus. Moderna said on Friday it had filed lawsuits in courts in the United States and Germany. Moderna is seeking compensation for alleged violations of intellectual property rights, but has not yet specified the amount. "We are filing these lawsuits to protect the innovative mRNA technology platform that we pioneered, invested billions of dollars in creating, and patented during the decade preceding the Covid-19 pandemic," said Moderna chief executive Stéphane Bancel. "We believe that Pfizer and BioNTech unlawfully copied Moderna's inventions, and they have continued to use them without permission," said Moderna chief legal officer Shannon Thyme Klinger, according to a press release. Moderna believes Pfizer and BioNTech copied two key features of Moderna's patented technologies which are critical to the success of mRNA vaccines, the press release said. BioNTech and Pfizer have faced other lawsuits in connection with their vaccines. During the course of a case involving Curevac which started in July, BioNTech said that all of the work of the firm was "original," and that it would defend itself against claims of patent infringement.
