Bayer, through its Monsanto subsidiary, has filed a lawsuit against Pfizer, BioNTech, and Moderna in Delaware federal court, alleging the companies are misusing Bayer’s messenger RNA (mRNA) technology in the production of their COVID-19 vaccines. A Bayer spokesperson confirmed the legal action on Tuesday.

The lawsuit centers on patents related to mRNA technology developed by Monsanto, which Bayer acquired in 2018. Bayer claims that the vaccine manufacturers have infringed upon these patents without proper licensing or compensation. Specific details regarding the patents in question and the financial damages sought were not immediately disclosed.

mRNA technology is a key component in the COVID-19 vaccines developed by Pfizer/BioNTech and Moderna. This technology uses genetic material to instruct the body’s cells to produce a protein that triggers an immune response, providing protection against the virus. While mRNA technology has been utilized in various fields for years, its rapid deployment in COVID-19 vaccines has brought significant attention to intellectual property and patent rights within the industry.

This lawsuit represents a significant legal challenge for the major vaccine manufacturers and could potentially impact future research and development related to mRNA technology. The case is expected to be complex and lengthy, potentially involving extensive patent litigation and expert testimony. Further updates will be provided as the case progresses.
