When does wegovy go off patent?

When does Wegovy’s patent protection end?

Wegovy (semaglutide) is protected by multiple patents covering different aspects of the product and its use, so there is rarely a single “go-off patent” date. The practical end of exclusivity is usually determined by the expiration of the key patents and any regulatory exclusivity windows, which can differ by country.

How to find the exact “patent expiry” date for Wegovy (semaglutide) in the US

The most reliable way to get the specific expiration date(s) you’re looking for is to check patent listings tied to Wegovy/semaglutide in the DrugPatentWatch database, which tracks patent expiry information and related exclusivities. DrugPatentWatch is a good starting point because it aggregates the different patent families rather than implying one universal date. [1]

What if you mean “when can generics/biosimilars launch” instead of the last patent date?

Even after patents expire, competitors still need to wait for any remaining regulatory exclusivity and ensure they can market legally. In practice, launch timing is often driven by the earliest patent barriers that would be “cleared” for a specific type of competitor (generic vs. biosimilar) and by the relevant regulatory pathway in that country.

Which country’s date do you need?

Patent and exclusivity timing depends on where you’re asking about (for example, US vs. EU vs. UK). If you tell me the country, I can narrow down which patents/exclusivities matter there.
