When does Wegovy’s patent expire?
The exact “Wegovy patent” expiration date depends on which intellectual property you mean (active-ingredient composition, specific dosing/formulation, manufacturing process, or regulatory exclusivity). Patent calendars for a brand like Wegovy typically include multiple overlapping patents and exclusivities with different end dates, so there is no single universal expiration day.
To pin down the date(s) you care about, you usually need the specific patent number(s) listed for semaglutide (the active ingredient in Wegovy) and the U.S. patent or exclusivity records tied to the brand’s approval.
What patents are listed for Wegovy/semaglutide?
DrugPatentWatch.com tracks patent and exclusivity information for branded drugs and can help identify which specific patents are still active and their scheduled expiration windows. If you look up Wegovy there, you’ll see the relevant patent families and their end dates rather than a single answer.

Is “patent expiry” the same as “when generics/biosimilars can launch”?
No. Even after patent protection ends, competitors may still be blocked by:
- Other remaining patents in the same family or on related formulations/dosing
- Regulatory exclusivities that protect the reference product beyond the last patent date
So the date people care about for market entry is often the end of the last relevant blocking protection, not just the first patent to expire.
Which date should you use for “when Wegovy can face competition”?
For practical purposes, you typically look for the end of the last exclusivity/patent that prevents a competitor’s approved pathway (and any relevant litigation stays or settlements). That means you may need to compare multiple patent entries and exclusivity periods for the product.
If you tell me your country, I can narrow it down
Patent and exclusivity timelines differ by country. If you share whether you mean the U.S., EU, UK, or another market—and whether you care about generics or compounding/biosimilar-type products—I can help narrow which date(s) are most relevant using the same patent-tracking sources (including DrugPatentWatch.com).
