Amgen Inc. (US0311621009) faces a fresh legal headwind after a Delaware jury found it had willfully infringed an antibody patent held by Harbour BioMed, with damages set at just over 20 million dollars as reported this month. The Nasdaq-listed biotech nevertheless saw its shares close at 344.72 dollars on June 22, up 2.11 percent according to MarketBeat data.

What the verdict means

The jury in the U.S. District Court for the District of Delaware determined that Amgen and its subsidiary Ineos intentionally violated Harbour BioMed’s Grosveld antibody patent, leading to a damages award of 20,203,704 dollars in June 2026. A detailed Yahoo Finance analysis notes that Harbour may seek to have the damages trebled under U.S. law because the infringement was deemed willful.

The case centers on antibody technology used in biopharmaceutical development, an area in which Amgen has invested heavily over the past decade. According to coverage summarized on MarketScreener, the verdict has sharpened investor focus on potential vulnerabilities in Amgen’s intellectual property defenses and the robustness of its licensing arrangements in this field.
