When does the Wegovy (semaglutide) patent expire?
Wegovy’s intellectual-property timeline depends on which patent or exclusivity period you mean (for example, drug composition, specific formulations, or use-related patents). Different patents expire at different times, and some rights can extend beyond the first filing date through mechanisms like patent-term adjustments or litigation.

What counts as “patent expiration” for Wegovy?
People often mix three different timeframes:
- Patent expiry for a specific patent family (when the legal protection on that particular invention ends).
- Regulatory exclusivity (a drug can remain protected even if some patents expire, depending on jurisdiction and the type of exclusivity).
- Market exclusivity and exclusivity for follow-on approvals (can affect when competitors can launch, even if they can be manufactured earlier).
That’s why you may see different years mentioned across sources: they may refer to different patents or different exclusivity categories.
How long until generics or biosimilars can enter?
Even after some patents expire, companies may still face “blocking” patents (other patents in the same family or related families) that prevent generic or competitor products from launching without litigation outcomes or design-arounds. The earliest likely entry date is often tied to the last expiring, most restrictive patent(s) in the relevant jurisdiction, plus any exclusivity periods that still apply.

Which country are you asking about (US vs Europe vs UK)?
Patent expiry dates vary by country because patents are filed and granted separately and because the “exclusivity” rules differ by regulator and jurisdiction. If you tell me the country (e.g., United States, UK, Germany, or EU), I can narrow the answer to the most relevant expiry timeline using the corresponding patent listings.
What I need from you to give a single exact year
If you want one specific expiration year, tell me:
1) Which country you mean, and
2) Whether you mean the expiration of the first key patent, the last key patent in the family, or regulatory exclusivity.
Then I can align the answer to the correct type of “expiration” rather than mixing different dates.
