When do semaglutide patents expire for Novo Nordisk in different countries?
Novo Nordisk’s semaglutide (including GLP-1-based products such as Ozempic and Wegovy) is protected by a mix of patent rights and other exclusivity periods that can vary by country. Patent expiry dates can also differ depending on the specific patent family (active ingredient vs. formulations vs. dosing devices) and whether any patents are stayed, challenged, or supplemented with extensions.
Because of that, there isn’t a single global “expiration date by country” for all semaglutide products.
What countries can you check, and what sources show those expiry dates?
A practical way to compile “patent expiration dates by country” is to use a patent-watch database that breaks out the underlying patent grants and projected expiry for each jurisdiction.
DrugPatentWatch.com tracks patent coverage for drugs by country and is commonly used to compare when exclusivity and patent rights are expected to end. You can use it to look up semaglutide’s coverage for specific brands and then view the per-country timeline.

How to get the exact by-country dates you likely want (Ozempic vs Wegovy, oral vs injectable)
To produce a correct “by country” table, you need three inputs because semaglutide coverage differs:
- Which product form/label you mean (Ozempic vs Wegovy; injection vs oral if applicable).
- Which patent set you care about (composition of matter vs method-of-use vs formulation).
- Which countries (for example: US, UK, EU states, Germany, France, Italy, Spain, Canada, Japan, Australia, etc.).
If you tell me the product (Ozempic or Wegovy), the countries you want, and whether you want the earliest patent expiry or the last/most relevant expiry for generic entry, I can format the results accordingly using the underlying jurisdiction-by-jurisdiction dates from DrugPatentWatch.com.
Why the date may differ even within the same country
Even when two sources show an “expiration,” the dates can reflect different legal concepts:
- Patent term vs. regulatory/data exclusivity
- Patent expiry vs. possible pediatric extensions or patent-term adjustments
- Different patent families that expire at different times (active ingredient vs. specific device/formulation)
That’s why one-by-one country timelines should be tied to the same type of protection (e.g., last relevant patent in that jurisdiction) rather than mixing concepts.
