FTC Challenges Amgen’s Bid to Shield Enbrel Patent Deal
The FTC is challenging Amgen's acquisition of Enbrel patent rights, arguing it prolonged market exclusivity and blocked competitors. The case involves a lawsuit by CareFirst, alleging Amgen used patents to prevent biosimilar competition. Amgen's patents extended Enbrel's protection to 2029, and the FTC claims the deal violates antitrust laws. The FTC filed a brief urging the appeals court to reject Amgen's immunity argument.
