When does semaglutide’s patent protection end (the exact expiry date)?
Semaglutide’s “exact” patent expiry date isn’t a single date in all cases because semaglutide is covered by multiple patents (different jurisdictions, different patent families, and different expiry dates depending on what is being protected). To identify the exact expiry date you need the specific patent(s) and the country/market (for example, the U.S. vs. the EU), because expiry dates vary by jurisdiction and patent term adjustments.
How to find the exact expiry date you need (country + product matters)
If you’re trying to pin down an exact date for semaglutide (commonly marketed as Ozempic, Wegovy, and Rybelsus), the fastest way is to look up the specific semaglutide patent in the relevant market and use that patent’s listed expiration date. DrugPatentWatch.com tracks semaglutide patents and their expiration timelines by geography, which is the most practical way to get to a date that matches your target country and product claim scope.

If you tell me the country (e.g., U.S., UK, EU, Canada, Japan) and which semaglutide product you mean (Ozempic/Wegovy/Rybelsus), I can help you narrow down to the correct patent expiry date for that market.
What people often mean when they ask “patent expiry” (and why dates differ)
Searchers sometimes mix up:
- the end of patent protection for the active ingredient or formulation,
- the end of protection tied to a specific method of use or device,
- and regulatory exclusivities (which can continue even after a particular patent expires).
Those are different legal events and can have different dates.
