A significant legal battle has unfolded in London, where Pfizer and BioNTech are challenging Moderna's patents related to mRNA technology used in COVID-19 vaccines. The dispute, part of a broader global litigation concerning intellectual property rights for the vaccine technology, began on Tuesday. Moderna is counter-suing, alleging that Pfizer and BioNTech infringed on two of its patents in developing their own mRNA COVID vaccines. This legal confrontation could have major implications for the control and profits derived from the groundbreaking vaccine technology that played a crucial role during the pandemic.
