When does the tirzepatide patent expire for Mounjaro?

When can generic or biosimilar versions enter after patent expiry?

Even after a particular patent expires, manufacturers usually still need to navigate any remaining patents and exclusivity protections covering tirzepatide.

For tirzepatide, you’ll often see multiple dates on tracking sites, which is why it matters to confirm the specific patent numbers and expiration dates.

How to confirm the exact “expiration” date you care about

- earliest patent term end (by patent)
- remaining listed patents that could still block launch
- any regulatory exclusivity period
