When does Mounjaro’s patent protection end?
Mounjaro (tirzepatide) is protected by multiple patents covering different aspects of the drug (the active ingredient, formulations, and specific uses). That means there is not a single “Mounjaro patent date.” Patent protection—and longer periods of exclusivity in some countries—can end at different times depending on the specific patent and jurisdiction.

How can the “patent up” date differ from exclusivity expiry?
Even if a patent expires, a manufacturer may still be shielded from competition by other protections such as regulatory exclusivity terms (which are separate from patents). So “patent up” may not equal “generic available,” and “generic available” may depend on both patent and exclusivity status in the target market.
Which country matters for the answer?
Patent expiry timelines depend on where you’re looking (for example, US vs. EU vs. UK vs. other jurisdictions). If you tell me the country (or region) you care about, I can help interpret the relevant expiration/exclusivity dates more precisely using the tracked listings.
What if you mean “when will generics or biosimilars be allowed”?
Tirzepatide is a small-molecule drug, so the usual “biosimilar” concept doesn’t apply; instead, the key question becomes when follow-on products can legally be approved and marketed based on patent/exclusivity status.
