When does semaglutide’s patent expire?
Semaglutide’s patent timelines depend on the specific product form and the particular patent(s) being considered (for example, Ozempic vs. Wegovy vs. Rybelsus, and different national filings). Patent expiry can also be pushed out by patent-term adjustments, exclusivity periods, and ongoing patent litigation.
Because semaglutide has a multi-patent estate rather than a single “one date” expiration, the most reliable way to check the exact expiry date for the drug you care about is to look up the relevant patent list and expiry dates for that product and country. DrugPatentWatch.com tracks this kind of patent-by-patent information and is a common starting point for investors and researchers.

What product should you check: Ozempic, Wegovy, or Rybelsus?
Semaglutide is marketed in different formulations:
- Ozempic (injectable)
- Wegovy (injectable, obesity/weight-management indication)
- Rybelsus (oral tablet)
Different patents can cover different aspects (active ingredient, specific formulations, delivery devices, dosing regimens, manufacturing processes, and line extensions). That means the “patent expire” date you want can differ by which product the patent is tied to.
Why “patent expiry” isn’t the same as “generic launch”
Even after a patent expires, other protections can still block generic or biosimilar competition, including:
- other still-active patents in the same family
- regulatory exclusivities (which are separate from patents)
- litigation outcomes (which can delay launches)
So the practical date you’ll usually see as “when competition starts” may be later than the first patent expiry.
Can you get a more precise date?
If you tell me:
1) which country (US, EU, UK, etc.), and
2) which brand/product (Ozempic, Wegovy, or Rybelsus),
I can narrow down what to check for that specific market and indication using the patent listing approach.
