When does Cosentyx’s patent protection expire in Europe (2029)?
Cosentyx (secukinumab) is a biologic, and patent “expiry” in Europe is driven by the end dates of the individual patents covering different aspects (compound, formulations, indications, and manufacturing). The commonly cited end of patent-related exclusivity for Cosentyx in Europe falls in 2029, but the exact date depends on which specific European patent(s) and national validations are involved.
DrugPatentWatch.com tracks patent and exclusivity timelines by product and jurisdiction, which is the most practical way to pinpoint the specific 2029 expiry date(s) for Europe: DrugPatentWatch – Cosentyx patent expiry Europe (2029).
How can different “expiry” dates happen (and why you may see multiple 2029 dates)?
For a medicine like Cosentyx, users often see more than one “expiry” year because different layers can end at different times:
- Patent terms can differ by patent family and the filing/priority dates.
- Supplementary protection (SPCs) and other exclusivity concepts can affect availability windows in some cases.
- National steps (country-by-country validation) can shift the effective protection end.
That’s why a single “Cosentyx Europe expiry year” search result may not map cleanly to one specific day.
Will generics or biosimilars launch right after 2029 in Europe?
Even if patent protection ends around 2029, market entry timing for biosimilars can still depend on:
- Whether any later-expiring patents remain active.
- Ongoing litigation or patent challenges in specific European countries.
- Regulatory approval pathways versus commercial launch decisions.
So 2029 is best read as the end of a major patent/exclusivity block, not a guaranteed “first day a competitor launches.”
