How long does novo nordisk have a patent on wegovy?

How long does Novo Nordisk’s patent on Wegovy last?

Wegovy’s protection is not set by a single patent date. Novo Nordisk’s exclusivity depends on multiple overlapping patents covering the active ingredient (semaglutide), manufacturing, and specific formulations/dosing, plus regulatory exclusivity periods. As a result, there isn’t one simple “patent end date” for Wegovy.

What “end date” should you look for—patent vs. exclusivity?

In practice, companies and analysts track two timelines:
- Patent expiration: the last date when specific listed patents are no longer enforceable.
- Regulatory exclusivity: additional time before certain competitors can get approval using an abbreviated pathway, even if a patent has expired.

Both can delay generic or biosimilar entry beyond the earliest patent expiry date.
