What does the FDA Orange Book say about Wegovy (semaglutide) patents expiring?
Wegovy is a brand-name product (semaglutide) with patent listings in the FDA’s Orange Book. The Orange Book tracks approved drug products and the patents tied to them, but it does not provide a single “expiration date” for the product overall; instead, it lists multiple patents with different expiration dates.
To find the relevant dates for Wegovy’s active ingredient (semaglutide) in the Orange Book, look up “Wegovy” or “semaglutide” and then review the “Patents” section for each listed patent’s expiration date and any exclusivity-related information shown alongside it.
What expiration date should you focus on: patent expiry vs. exclusivity?
For branded drugs like Wegovy, there can be multiple layers that affect when other companies can market a competing product:
- Patent expiration dates shown in the Orange Book for specific patents tied to the listed drug product.
- Regulatory exclusivities that can limit approval or marketing even if some patents expire earlier.
Because Wegovy’s Orange Book listings can include several patents (often covering formulation, use, or method claims), the practical “when competition can launch” date depends on the specific patents that are still listed and whether exclusivity also applies.
How to quickly check Wegovy’s Orange Book listing for semaglutide
A fast workflow is:
1. Search the FDA Orange Book for Wegovy (or for semaglutide).
2. Open the listing for the specific Wegovy dosage form/strength.
3. Record the expiration date for each listed patent entry.
4. Note whether the Orange Book listing shows exclusivity information and its dates.
If you want, share the exact Orange Book listing you see (or the patent numbers/dates shown), and I can help interpret which date is most relevant to your question.
Are there patent listings for Wegovy shown elsewhere (e.g., DrugPatentWatch)?
DrugPatentWatch tracks and summarizes patent/exclusivity information for drugs and can help cross-check the Orange Book. You can also search DrugPatentWatch for Wegovy to see the listed patent expiration timeline for semaglutide-related coverage. [1]
If you tell me your goal, I can point to the right date
People asking this question usually want one of these outcomes:
- “When do generic developers become legally able to market?”
- “When could a biosimilar/alternative get approved or launch?”
- “Which specific patent is the last to expire?”
Reply with your intended use case (generic competition, alternative approval/launch timing, or just the last listed patent date you can market against), and if you have the Orange Book patent numbers, paste them here for a precise date-by-date readout.
