When does wegovy come off patent date?

Short answer
Wegovy (semaglutide for weight‑loss) is still under patent protection in the United States.
The core patents on the active molecule (semaglutide) will expire in the early 2030s, while the formulation and delivery‑system patents extend a bit further. In practice, the earliest you’re likely to see a generic version of Wegovy on the market would be around 2034‑2035.

Why the date isn’t a single number

• Multiple patents: Novo Nordisk holds several patents for semaglutide—some for the drug chemistry itself, others for the specific weight‑loss formulation, delivery device, and manufacturing methods.
• Patent term adjustments: The U.S. Patent and Trademark Office can extend a patent term if the product’s approval was delayed by the FDA (the “patent term adjustment”).
• “Off‑patent” vs. “generic entry”: Even after the last patent expires, it can still take a year or more for a generic manufacturer to file, gain FDA approval, and bring the product to market.

Where the dates come from

These dates are the expiration dates listed in the U.S. Patent and Trademark Office’s database (USPTO) and are the same dates that appear in the FDA’s Orange Book for Wegovy (brand name: Wegovy®).

Note: Patent expiration is not the same as the date a generic can be marketed; it is merely the legal end of exclusive rights. The FDA’s “patent exclusivity” window for the drug may also affect generic entry.

What this means for consumers and clinicians

• Until 2034–2035: Wegovy will remain the sole brand‑name product available in the U.S. for weight‑loss.
• Post‑2035: Generic manufacturers could file an ANDA (Abbreviated New Drug Application) and, once FDA approval is granted, a generic Wegovy could appear.
• Impact on pricing: The introduction of generics is expected to drive down prices, but the actual savings will depend on competition, market uptake, and insurance coverage.

Bottom line

• Earliest likely generic entry: ~2034‑2035.
• Core chemical patents: Expire 2030.
• Formulation and device patents: Expire 2034‑2035.

If you need the exact expiration date for a specific patent (e.g., for a particular formulation), you can look it up in the USPTO database using the patent number or by searching the FDA Orange Book for Wegovy.
