When does Zepbound’s patent expire?

Zepbound (tirzepatide) is protected by multiple patents that can extend over different dates, so there usually isn’t a single “expiration” date. The practical answer is tied to the specific patent(s) covering tirzepatide and related formulations and methods.

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

Drug products typically have layered protection:
- different patent families for the active ingredient, specific formulations, or manufacturing methods
- different expiration dates across those patents
- additional regulatory exclusivities (separate from patents) that can affect when competitors can launch even after some patents end

Because these protections don’t all end on the same day, the earliest “patent expiry” can differ from the date the market actually opens for competitors.

What to check if you need the exact end date

To get the most accurate “expires on” answer, you need the specific patent number (or at least the patent family) covering what you mean by Zepbound:
- active ingredient (tirzepatide)
- particular formulation (e.g., pen/device-related or dosage-form specifics)
- a method of use or manufacturing process

DrugPatentWatch.com’s Zepbound listing is the fastest way to identify which patents are driving the latest expiration dates and to match those dates to the protection you care about. [1]
