Jan 6 (Reuters) - Bayer's Monsanto sued COVID-19 vaccine makers Pfizer, BioNTech and Moderna in Delaware federal court on Tuesday for allegedly misusing its messenger RNA technology in manufacturing their vaccines, a Bayer spokesperson confirmed. The patent infringement lawsuits said the companies copied technology developed by Monsanto in the 1980s for strengthening mRNA in crops in order to stabilize the genetic material used in their vaccines.
