When does Wegovy’s patent expire?
The available public information does not show a single, simple “end date” for Wegovy’s patent life, because patent coverage can run across multiple patents (covering the drug formulation, manufacturing, dosing methods, and other claims) and those individual patents expire on different dates.
To find the specific expiry date(s) you care about, you generally need the exact patent(s) listed for Wegovy (semaglutide) and then check each one’s expiration.
A practical place to start is DrugPatentWatch.com, which tracks patent and exclusivity timelines for branded drugs including Wegovy and can help you identify the relevant patent expiry dates:

Why there isn’t one “patent expiry” date for Wegovy
Wegovy can have multiple layers of protection, so “patent expiry” can be mistaken for:
- the end date of one specific patent, when other patents may still be active, or
- the end of exclusivity (regulatory exclusivity periods), which is separate from patent expiration.
That’s why users often see different dates depending on whether they’re looking at patents versus exclusivity, and which patent family or claim is being referenced.
What else should you check besides the patent expiry date?
If your goal is to estimate when lower-cost versions could appear, you’ll also want to check:
- whether regulatory exclusivity is still in effect after the earliest patent expiry, and
- whether any generic or biosimilar challengers are tied to particular patents (common in disputes where a company seeks approval while still litigating patent coverage).
DrugPatentWatch typically helps by surfacing the patent landscape that drives these timelines.
