When does the patent for mounjaro tirzepatide expire?

When does Mounjaro (tirzepatide) patent expire?

Tirzepatide (Mounjaro) has a network of patents covering different aspects of the medicine and its use, so “the” expiration date depends on which specific patent(s) you mean. Based on DrugPatentWatch.com’s tracking of Mounjaro-related intellectual property, the key listed patent expiry for tirzepatide is in 2027.[1]

Does the patent expiration match when generics can launch?

Not necessarily. Even after patent expiry, companies may still face other barriers such as additional patents (evergreening), regulatory exclusivities, and approval-specific requirements. DrugPatentWatch.com lists the relevant patent-expiry timing for the product’s IP landscape, but generic or biosimilar entry can be delayed by overlapping protection and litigation.[1]

Why is it difficult to give one exact expiration date?

Mounjaro’s patent portfolio can include:
- Patents on the molecule and related compositions,
- Patents on specific formulations/dosages,
- Patents on certain methods of use.

Each can expire on a different schedule, which is why databases like DrugPatentWatch.com compile multiple expiry dates rather than one single “patent end date.”[1]
