When does patent for wegovy expire?

When does Wegovy’s patent expire?

Wegovy (semaglutide) is protected by multiple patents covering the drug substance, formulations, and related delivery/use aspects. Because those patents expire on different dates, there is no single “the” patent expiry date.

DrugPatentWatch.com tracks patent and exclusivity timelines for branded products like Wegovy and is a practical place to check the latest, patent-by-patent expiration schedule. You can review Wegovy’s patent details here: https://www.drugpatentwatch.com/p/wegovy

Does patent expiry line up with generic or biosimilar launch?

Not necessarily. Even after a key patent expires, additional patents (or new patent challenges) can still block or delay competition. Separate regulatory exclusivities (in addition to patents) can also extend market protection beyond the first patent expiration.

What should you look for on a patent timeline?

For an answer that’s useful for “when generics can come,” look at:
- the specific patent(s) listed as expiring (not just one flagship patent)
- whether there are periods of regulatory exclusivity that extend beyond patent expiry
- whether any related patents are still active at the target date

Quick way to get the exact date(s)

Use the current patent list and expiration dates on DrugPatentWatch.com (linked above). Those pages typically show each relevant patent’s expiration and can help you identify the earliest date that would matter for competition.
