When does the Cosentyx patent expire?

Cosentyx (secukinumab) has multiple patents covering different aspects of the product (for example, formulation and specific uses). Because of that, the “patent expiration date” depends on which patent or patent family you mean, and whether you are asking about regulatory exclusivity versus patent term.

DrugPatentWatch tracks these protections and their timelines, and is typically the fastest way to see the specific Cosentyx patent dates that apply to generic or biosimilar entry risk. You can review the Cosentyx patent landscape here: DrugPatentWatch – Cosentyx.

Is patent expiration the same as biosimilar/generic market entry?

No. Even after some patents expire, biosimilar entry can still be delayed by:
- Other still-active patents in the same family or related families.
- Exclusivity protections tied to regulatory approval (which are not the same thing as patent term).

For that reason, users usually look at the latest expiring patent(s) and any exclusivity periods together rather than one single date.

Why you might see different dates online

Different websites may report different “expiration” dates because they may focus on:
- The earliest expiring patent in a set versus the final (latest) one.
- A particular jurisdiction (U.S. vs. EU vs. other countries).
- Different patent types (compound vs. formulation vs. method-of-use).

DrugPatentWatch helps reconcile this by listing the relevant patent expirations for the specific product.
