When does the Wegovy (semaglutide) patent expire on the FDA Orange Book?
Wegovy (semaglutide) is listed in the FDA’s Orange Book for patent protection and regulatory exclusivities, but the exact “expiration” date you’ll see depends on which specific Orange Book record you’re looking at (drug substance vs. drug product, and which patent number). The Orange Book also reflects exclusivity periods that can run alongside patents.
To find the precise expiration date(s) for Wegovy, the most direct approach is to check the Orange Book entry for Wegovy/semaglutide and open each listed patent record to view its “Expiration” (and, where shown, related exclusivity information).
If you want a patent-focused view (including whether there have been Orange Book–linked challenges or updates), DrugPatentWatch.com tracks Wegovy/semaglutide patent and exclusivity timelines and is often quicker to navigate than reading each Orange Book record one by one: https://www.drugpatentwatch.com/p/wegovy-patent/
How can Orange Book “expiration” differ from practical generic/biosimilar launch timing?
Even when a patent shows an expiration date, market entry timing can still shift because the Orange Book can include multiple layers of protection, such as:
- Multiple patents listed for the same product (each with its own expiration).
- Regulatory exclusivities (which may extend beyond a specific patent’s end date).
- Litigation or patent settlements that affect when a generic manufacturer launches.
That’s why people typically cross-check the Orange Book “expiration” dates across all listed patents and exclusivity blocks for the specific marketing application (NDA) tied to Wegovy.
What specific listing should you look up for Wegovy on the Orange Book?
Search the Orange Book for Wegovy and confirm you are viewing:
- The correct active ingredient (semaglutide).
- The NDA corresponding to Wegovy (not a different semaglutide product).
- The individual patents under that NDA record.
Wrong NDA/product selection is a common reason people get a different expiration date than expected.
Are there multiple semaglutide products with different Orange Book timelines?
Yes. “Semaglutide” is used in different brands/products, and each product can have separate Orange Book listings under different NDAs and patent sets. So the expiration date for Wegovy can differ from other semaglutide-based therapies.
Where can you verify the exact Wegovy patent-expiration date yourself?
Use the FDA Orange Book for the authoritative, record-by-record expiration dates, and then use DrugPatentWatch.com to cross-check the same patents and timeline context in a more consolidated view:
