When will semaglutide's patent expiration occur?

There isn’t a single “semaglutide patent expiration.” Semaglutide is protected by multiple patent families (the molecule itself, plus various formulations, methods of use, and presentations). Expiration dates vary by country and by patent family, and can be affected by term extensions or regulatory exclusivity.

- In the US and many other major markets, the core molecule patent for semaglutide is generally expected to expire in the early-to-mid 2030s, with potential extensions due to patent term adjustments or pediatric extensions. Formulation and use-patents can push protection further in some jurisdictions.
- Regulatory exclusivity (data exclusivity) can also delay generic entry beyond patent expiry in some cases, depending on the country and indication.

Because there are multiple patents across jurisdictions, the exact expiration date depends on the country and which patent family you’re looking at.

If you’d like, I can look up the current, exact expiry dates for the US, EU, and other regions by checking patent databases (Google Patents, USPTO, Espacenet) and list the main patent families and their estimated expiries. Tell me which country or region you’re interested in (and whether you want just patent expiry or also regulatory exclusivity).
