Prozac patent?

Prozac is fluoxetine. The core patent protection on the chemical compound and its basic use has expired in the U.S. (and in most major markets), and generic fluoxetine is available. Some countries may have had additional patents on specific formulations, dosages, or new-use claims, which could affect exclusivity there, but there’s no broad patent protecting the core compound in the U.S. anymore.

If you’d like, tell me the country you’re interested in and whether you want the status for the compound patent or any formulation/use patents, and I can guide you or look up the current status.
