GSK files lawsuit against Moderna

16 October 2024

UK pharma major GSK (LSE: GSK) has sued USA-based Moderna (Nasdaq: MRNA) this week, accusing the latter of violating patents protecting GSK’s COVID-19 vaccine.

According to reports from Reuters, GSK claims that Moderna’s mRNA technology infringes several GSK patents covering similar innovations.

The suits allege that nanoparticles used in Moderna's Spikevax COVID-19 vaccine and recently approved mRESVIA (mRNA-1345) vaccine for RSV – which competes with GSK's $1.7 billion blockbuster RSV vaccine Arexvy – infringe various patents held by GSK. Specifically, it refers to "lipid mRNA vaccine formulation technology" that predates the COVID-19 pandemic by more than a decade and stems mainly from an R&D team led by renowned vaccine specialist Christian Mandl.
