AstraZeneca's Alexion Pharmaceuticals is facing a lawsuit in Massachusetts for allegedly misusing patents to maintain a monopoly on its drug Soliris, which treats rare blood disorders. EmblemHealth claims that Alexion wrongfully obtained new patents to block biosimilars, violating U.S. antitrust laws and potentially causing overpayments exceeding $2 billion. The lawsuit seeks to end AstraZeneca's monopoly and demands monetary damages. Soliris costs over $500,000 per patient annually, and AstraZeneca reportedly earned over $1.4 billion from its sales in the first half of 2024.
