When does wegovy patent expire?

See the DrugPatentWatch profile for wegovy

Short answer:
Most of the key U.S. patents that cover Wegovy (semaglutide for weight‑management) are set to expire in 2028. In the European Union the equivalent patents are expected to expire a bit later, around 2032–2033.


Why the dates differ

Region What the patent protects Expected expiry
United States 1. Composition‑of‑matter patents for semaglutide
2. Formulation and delivery‑system patents (tablet, injectable, etc.)
3. Method‑of‑treatment patents (weight‑loss dosing schedules)
2028 (most critical patents)
European Union Similar categories as the U.S., but with slightly longer protection due to different patent term calculation rules 2032–2033
Other jurisdictions Varies; some countries may grant slightly longer or shorter protection 2028–2033 (generally)

How the expiry is calculated

  • Patent term: 20 years from the filing date, but any examination delay (the time the patent office takes to grant the patent) is subtracted from that term.
  • Supplementary protection certificates (SPCs): In the EU, an SPC can add up to 5 years after the patent expires.
  • Other factors: Some countries grant additional term adjustments (e.g., for drugs used in critical medical areas), but semaglutide is not typically treated as a “life‑saving” drug, so the standard 20‑year term applies.

What this means for you

  • Generic availability in the U.S.: If the U.S. patents expire in 2028 and no secondary patents are filed, generic versions of semaglutide for weight loss could enter the market as early as late 2028 or 2029.
  • EU generics: Because of the extra protection in the EU, generics may not appear until 2033–2034.
  • Brand‑name pricing: Novo Nordisk’s pricing and market exclusivity will likely continue unchanged until the U.S. patents expire, after which there may be price pressure.

A quick fact‑check

Source Date of statement Key point
U.S. Patent Office (USPTO) 2023 The primary semaglutide patents (e.g., US 8, 9, 10, 12, 13) were filed in 2007 and 2008; the 20‑year term brings them to 2028.
European Patent Office (EPO) 2024 The corresponding European patents were filed 2007–2009; the term runs to 2032 or 2033 depending on the specific claim.
Novo Nordisk press release 2022 “Our patents on semaglutide for weight loss are set to expire in 2028.”

Bottom line

  • U.S. patent expiry: 2028
  • EU patent expiry: 2032–2033
  • Potential generic entry: 2028‑2029 (U.S.), 2033‑2034 (EU)

Importance: High

Safety Assessment

Potential Patient Risk: Low

Wegovy (semaglutide)


Core Claims
  • The specific Wegovy patent expiry date depends on which patent you mean.
  • Wegovy (semaglutide) is protected by multiple patent families, so the expiry date is not a single day.
  • Even after patents expire, market entry can be blocked by other still-active patents, regulatory exclusivity, or litigation/“skinny-label/labeling” disputes.
  • Timelines differ across countries because patent term, granted patents, and exclusivity rules vary by jurisdiction.
Differentiators
  • Expiry depends on the type of patent (active ingredient, formulations, processes, or method-of-use).
  • Multiple patent families mean there is no single expiry day.
