Pfizer and Moderna Clash Over mRNA Vaccine Patent Rights in High-Stakes Legal Battle

Pfizer and Moderna, two pharmaceutical giants at the forefront of the COVID-19 vaccine development, are embroiled in a high-stakes legal battle over the patent rights to the innovative mRNA technology used in their vaccines. The dispute, which has far-reaching implications for the future of mRNA-based therapeutics, has escalated into a global litigation spanning multiple countries, including the United Kingdom, Germany, the Netherlands, Belgium, and the United States.

The legal showdown began when Pfizer and its German partner BioNTech filed a lawsuit in the UK's High Court, seeking to revoke Moderna's patents on the mRNA technology. Pfizer and BioNTech argue that Moderna's developments were obvious improvements on previous work and do not warrant patent protection. In response, Moderna has accused Pfizer and BioNTech of copying the mRNA technology it had pioneered and patented before the pandemic, alleging patent infringement.

Moderna, which had initially pledged not to enforce its COVID-19 vaccine-related patents during the pandemic, has now changed its stance. The company is seeking damages from Pfizer and BioNTech for alleged infringement of its patents since March 2022, as the fight over the potentially profitable mRNA technology intensifies. Moderna claims that it is filing the lawsuits to protect the innovative mRNA technology platform it developed and patented over the decade preceding the pandemic, which enabled it to produce a safe and effective COVID-19 vaccine quickly.

Why this matters: The outcome of this legal battle could have significant implications for the future development and accessibility of mRNA-based vaccines and therapeutics. It also highlights the complex interplay between intellectual property rights, scientific innovation, and public health in the context of a global pandemic.

The legal proceedings are expected to be lengthy and complex, with the London High Court dividing the case into three separate trials. One trial will examine Moderna's 2020 commitment not to enforce its vaccine patents during the pandemic, while the others will focus on the validity of the patents themselves. The battle extends beyond the UK, with parallel proceedings ongoing in several other countries and at the European Patent Office.

The stakes are high for both companies, as the COVID-19 vaccines have generated substantial revenue. In 2022, Pfizer's Comirnaty vaccine brought in $11.2 billion in sales, while Moderna's Spikevax earned $6.7 billion. The legal dispute also centers around the groundbreaking work of Katalin Kariko and Drew Weissman, who won the 2023 Nobel Prize in Medicine for their discoveries that were "critical for developing effective mRNA vaccines against COVID-19 during the pandemic".
