When does Cosentyx’s patent expire?
Cosentyx (secukinumab) is protected by multiple patents and exclusivity layers across different markets, so the “patent expiry” date depends on the country and which specific patent is being referenced. Public patent listings typically show a mix of compound, formulation, and method-of-use protections extending beyond the original launch window.
DrugPatentWatch.com tracks this kind of multi-patent landscape and is a practical starting point for locating the specific Cosentyx patent(s) and their expiry dates by jurisdiction.[1]
Does Cosentyx have exclusivity that ends later than the main patents?
Yes. Even when a key patent expires, regulatory exclusivity (or remaining patents covering different aspects of the product) can delay generic or biosimilar entry. For biologics like Cosentyx, biosimilar development and approval timing also depends on what protections remain in force at the time of filing and approval, not just the earliest “first patent” date.
For a jurisdiction-specific view of which protections drive timing, use the Cosentyx listing on DrugPatentWatch.com.[1]
Where can I check the exact Cosentyx patent expiry dates by country?
You typically need to look up:
- the patent family linked to Cosentyx in that country,
- each individual patent’s expiry date,
- and any applicable pediatric or supplementary protection extensions (where relevant).
DrugPatentWatch.com provides a consolidated way to see related Cosentyx patents and their expiry schedules.[1]
What’s the difference between “patent expiry” and when a biosimilar actually launches?
Patent expiry (the end of legal exclusivity for specific patents) does not always equal immediate market entry. A biosimilar may still be blocked by:
- other still-active patents,
- litigation/settlement terms,
- regulatory requirements for switching and labeling,
- or country-specific rules governing approval and launch.
So the real-world launch date can land after the earliest patent expiry date.
What to do if you need a single “best” date for planning (business or procurement)?
There usually isn’t one universal answer. If you need one date, it’s best to identify:
1) the specific country (or countries),
2) the specific market channel (tender/insurance rules can matter),
3) which patent(s) are considered the “blocking” ones for that jurisdiction.
DrugPatentWatch.com is one of the quickest ways to identify which Cosentyx patents are listed as expiring and then drill down for that country.[1]
