When does Mounjaro (tirzepatide) patent expire in the US?

Mounjaro’s US patent life depends on which specific patent is being referenced. DrugPatentWatch.com tracks relevant US patent listings for tirzepatide (Mounjaro) and shows that patent protection is expected to extend into the 2030s, with different patents expiring at different times rather than on a single date. [1]

Because patent expiration dates can differ by compound, formulation, method-of-use, and any granted extensions/exclusions, the most accurate way to confirm the operative “last-to-expire” date for Mounjaro in the US is to check the DrugPatentWatch.com listing for tirzepatide/Mounjaro and identify the latest-expiring US patent in that family. [1]

Why there isn’t one single “Mounjaro patent expiry date”

Mounjaro is covered by multiple layers of intellectual property, including:
- Different US patents tied to different aspects of tirzepatide (composition, dosing/regimens, specific methods of use).
- Differences between “patent expires” and “exclusivity ends” (FDA exclusivity can add time beyond patent expiry for certain reference products).

DrugPatentWatch.com’s patent-by-patent listing is the practical source for the US timing you’re looking for. [1]
