When does the semaglutide patent expire?

There isn’t a single expiration date for semaglutide. It’s protected by multiple patent families (covering the molecule itself, salts/forms, formulations, delivery devices, and uses) and those patents expire at different times depending on the country. In short:

- The core “composition of matter” patents for semaglutide and some related molecule patents are older and many have expired or are due to expire in the late 2020s, but there can be other patents (formulations, injectors, oral tablet formulations, methods of use) that extend into the 2030s in some jurisdictions.
- In addition to patents, biologics like semaglutide often enjoy regulatory exclusivities that delay generic/biosimilar competition. In the US, data exclusivity under the Biologics Price Competition and Innovation Act provides about 12 years of protection for the data, which can delay entry of biosimilars even after patents lapse. In the EU, there are separate data and market exclusivity protections that can also push competition out by several years.

If you want a precise expiry date, tell me:
- the country (or region) you’re interested in,
- whether you want the status of the molecule/active ingredient patents or of specific formulations (Ozempic injector, Rybelsus oral tablet), and
- whether you want to include regulatory exclusivities (which can matter for biosimilar entry).

I can then look up the current patent statuses for those specific patent families. Note: for legal decisions, consult a patent attorney or the official patent databases.
