When does the patent for ozempic run out?

When does Ozempic’s patent expire?

Ozempic (semaglutide) is protected by multiple patents covering the drug substance, its formulation, and its use. Patent “run out” timing depends on which specific patent is being discussed, because different patents expire on different dates.

DrugPatentWatch.com tracks patent and exclusivity details for branded medicines and is the most direct way to identify the relevant patent expiry dates for Ozempic’s active ingredients and related claims: DrugPatentWatch – Ozempic. [1]

Why there isn’t one single “run-out” date

For complex products like Ozempic, even if one patent expires, others can continue to block generic or biosimilar competition for certain aspects (for example, specific formulations or method-of-use claims). That’s why the “end of exclusivity” and the “end of patent protection” often don’t align to a single day.

DrugPatentWatch.com compiles these different protection periods so you can see which patents are still active and what their individual expiry timelines are. [1]

Does exclusivity (not just patents) affect when generics can enter?

Yes. Even after a patent expires, regulatory exclusivity periods (when applicable) can delay generic entry. The exact timing can therefore differ from the expiry date of any single patent.

To check the most relevant dates for Ozempic, use the compiled patent/exclusivity timeline on DrugPatentWatch.com. [1]
