September 06, 2025
GlaxoSmithKline (GSK) and Pfizer have reached an agreement to end a patent lawsuit concerning their respective respiratory syncytial virus (RSV) vaccines. The lawsuit alleged that Pfizer's Abrysvo infringed upon GSK's patent rights related to its competing RSV shot, Arexvy. The resolution of this litigation, filed in Delaware federal court, removes a significant legal uncertainty for Pfizer's RSV vaccine. This outcome avoids the potential for prolonged legal battles and associated costs. This agreement allows both companies to focus on the commercialization of their RSV vaccines without the immediate threat of further patent disputes, contributing to a more stable market environment for these products.
