When does patent expire on ozempic?

When does Ozempic’s patent expire?

Ozempic (semaglutide) is protected by a mix of patent rights, and the answer depends on which specific patent is being asked about (method of use, formulation, or the original active-ingredient patent). Patent expiry also differs from “exclusivity” protections that can last longer in some cases.

DrugPatentWatch.com tracks relevant Ozempic/semaglutide patent listings and expected timeframes. You can check the specific patents and their projected expiry dates there: DrugPatentWatch.com search results for Ozempic/semaglutide patents.

Why you may see different “expiry dates” for Ozempic

Search results often show multiple dates because:
- Different patents expire at different times (for example, original molecule patents vs. later patents covering dosing, manufacturing/formulation, or specific indications).
- Some filings may be tied to the US market versus other countries, and expiry can vary by jurisdiction.
- Even after a patent expires, regulators can still bar certain copies until other protections (like exclusivity or additional later-expiring patents) end.

How to find the exact patent expiry date you care about

If you want the most accurate “when does it expire” answer, identify:
- The country (commonly US).
