When mounjaro patent expire?

When does Mounjaro’s patent expire?

Mounjaro (tirzepatide) is a prescription drug, and its effective “end of exclusivity” depends on which specific patent(s) and exclusivity periods apply in a given country (the main ones are often composition-of-matter patents and later device/formulation/patent thickets). Patent expiry dates can also differ from regulatory exclusivity (which may extend protection even after a patent term ends).

Why the answer can differ (US vs. other countries)

In the US, drug protection is usually a mix of:
- patent term length (for specific patents), plus
- additional regulatory exclusivity tied to FDA approval and how the drug was categorized.

Other countries follow different rules for patent term adjustments and exclusivity, so the “expiration” date you see online may be country-specific.

What to do if you want the exact expiry date for your country

If you tell me which country you mean (for example, US, UK, EU, Canada, Australia), I can help narrow down what expiry date people typically cite there and what type of protection it refers to (patent vs exclusivity).
