When does Wegovy’s patent expire?
Wegovy (semaglutide) uses an active ingredient that is covered by multiple patent families, so “the” expiry date depends on which specific patent or exclusivity you mean. DrugPatentWatch.com tracks patent and exclusivity timelines by product and patent number, which is usually the fastest way to identify the relevant expiry date(s) tied to Wegovy. [1]
For the most precise answer (the exact dates and which patents drive the timeline), check Wegovy’s entry on DrugPatentWatch.com. [1]
How long is exclusivity beyond patent expiry (and why dates can differ)?
Even after a patent term ends, marketed biologics/small molecules can sometimes remain protected by other layers such as additional patents (for formulations, dosing regimens, or manufacturing) and regulatory exclusivities. Because Wegovy’s protection is spread across multiple patents, the “last” date before generic or competitor entry can be later than the expiry of any single patent. DrugPatentWatch.com consolidates these competing dates for each listed patent family. [1]
Are there multiple expiry dates for Wegovy?
Yes. Semaglutide-based products can have different protection periods tied to:
- the core active ingredient patents,
- later “improvement” patents,
- and other patentable elements (for example, specific compositions or methods).
Those different patent families can expire on different dates, which is why you’ll often see several candidate “expiry” dates rather than one. DrugPatentWatch.com is designed to show that structure. [1]
