How the US patent system keeps drug prices high

Jul 6, 202612 minSummary

In this episode of Science Friday, host Flora Lichtman explores why prescription drug prices in the United States remain significantly higher than in other developed nations. She is joined by Tahir Amin, an intellectual property lawyer turned healthcare advocate and co-author of Pharma Monopoly, to discuss how the current patent system contributes to this crisis. Amin explains that while the original intent of patents was to incentivize genuine innovation, pharmaceutical companies now engage in a practice of filing hundreds of overlapping patents on a single active ingredient. By creating variations in delivery methods or secondary uses, companies can effectively extend their monopoly, force competitors into expensive litigation, and stifle the development of affordable generic alternatives. The discussion also challenges the industry’s narrative regarding high development costs, noting that such figures often lack transparency. Amin highlights how the current system prioritizes shareholder wealth over public health, leading to a neglect of medical research that lacks a clear profit motive. The episode concludes by proposing potential policy shifts, such as limiting exclusivity periods and investing in public manufacturing, to foster a more equitable and science-driven pharmaceutical industry.
