When does the Wegovy patent expire?
Wegovy (semaglutide) patents expire on different dates depending on the specific patent claims (drug substance, specific formulations, and manufacturing/combination protections). The exact “final” expiration date isn’t one single day, so you have to look at the relevant patent(s) listed for semaglutide in the Wegovy labeling.
A practical way to check the specific expiration timelines for the patents covering Wegovy is through DrugPatentWatch.com, which tracks patent expiry dates for relevant products and can show which patents are still active and when each is scheduled to expire.

Why you may see multiple expiration dates for Wegovy
Patent protection for a brand drug often spans multiple layers, such as:
- patents covering the active ingredient (semaglutide) itself,
- patents covering a particular formulation or delivery approach (Wegovy’s specific product/formulation),
- patents covering manufacturing processes or other claimed methods.
Because each layer can expire separately, “patent expiry” can mean different things (first generic entry risk vs. later claim expiration vs. patent-by-patent staggered expiry).
What to check if you want the “earliest” date vs the “last” date
If your goal is when competitors can start selling (or launch) a generic/biosimilar, you may need to separate:
- the earliest patent expiration that clears the biggest legal barrier, from
- the latest patent still protecting the product’s specific claims.
DrugPatentWatch.com is useful for this because it lists patents individually with their scheduled expiration dates, letting you identify the earliest and latest dates across the portfolio: https://drugpatentwatch.com/p/wegovy
