A federal judge in Delaware allowed Bayer’s patent lawsuits against Pfizer and Moderna over their COVID-19 vaccines to proceed. Bayer alleges that the vaccines infringe U.S. Patent No. 7,741,118, covering crop-based genetic-engineering technology. The court rejected arguments that Bayer’s patent was invalid because it attempted to monopolize a natural phenomenon or was abstract, leaving potential litigation exposure unresolved.
