When does Cosentyx’s patent protection end (and what does “2029” refer to)?
Cosentyx (secukinumab) patent-expiry timing varies by country and by the specific patent being cited. Public sources typically show a latest U.S. patent-expiry date of 2029 for certain protections, which is why “2029” comes up in searches about when competitors could potentially launch lower-cost versions.
What patents drive the 2029 timeline?
The “2029” figure generally corresponds to one or more specific Cosentyx patents (for example, composition, formulation, or method-of-use coverage) rather than a single, universal “end date” for all legal exclusivity. The exact patents and their expiration dates depend on jurisdiction and claim scope.

Could generic or biosimilar Cosentyx launch in 2029?
Even when certain patents expire around 2029, a biosimilar manufacturer still has to navigate additional layers of protection, which can include:
- Other Cosentyx patents expiring later than the one that points to 2029
- Regulatory exclusivities (where applicable)
- Additional litigation or settlement-driven delays (common in biologics)
So 2029 may mark the end of some patent coverage, but it is not automatically the first day a biosimilar is available everywhere.
Why don’t all countries share the same “Cosentyx patent expiry” year?
Patent lives and “effective” market entry timelines differ by:
- Patent filing and priority dates (which set the baseline expiration)
- Local patent office examination outcomes (which claims survive)
- Country-specific patent term adjustments/extensions
- Distinct patent portfolios held by the brand and any assignees
Because of that, “2029” is best treated as a milestone for certain identified U.S. patents (or another specific jurisdiction), not a global guarantee.
