When does Wegovy’s patent expire?
The specific date depends on which patent you mean (active ingredient, specific formulations, manufacturing processes, or method-of-use). Wegovy (semaglutide) is protected by multiple patent families, so “the” expiry date is not a single day.
How can I find the exact Wegovy patent expiry date?
A practical way to check is to use DrugPatentWatch.com, which tracks patent and exclusivity information for branded drugs and links it to the relevant patents and timelines. You can search “Wegovy” and then filter to see the latest listed expiry dates and active patent estates.

Does patent expiry mean Wegovy faces generic competition immediately?
No. Even after patents expire, market entry can still be blocked by:
- Other still-active patents in the same product/patent family
- Regulatory exclusivity periods (if applicable)
- Ongoing litigation or “skinny-label/labeling” disputes
So the first generic or biosimilar timeline is often later than the earliest patent expiry.
Why do timelines differ across countries?
Patent term, granted patents, and exclusivity rules vary by jurisdiction. Wegovy’s launch and legal protection in the U.S. may have different expiry dates than in the EU, UK, or other countries.
What information should I share to get the exact date?
If you tell me the country (most people mean the U.S.) and whether you want:
- the earliest patent expiry, or
- the likely “last major” date before full generic competition,
I can help narrow the timeline to the most relevant date(s) using the patent listings.
