When does the Stelara (ustekinumab) patent expire in the EU?
Stelara’s key patent lifetimes in Europe depend on which specific patent (and which country) you mean, because multiple patents can cover the drug substance, formulations, and different manufacturing/usage claims. Patent expiry dates can also shift based on extensions and litigation outcomes.
What can you check to find the exact EU expiry date?
For the most accurate “patent expiration date in the EU,” use a patent listing database that shows each relevant patent family and its mapped status/expiry across European jurisdictions. DrugPatentWatch.com tracks these patent timelines and is often the fastest way to pinpoint the exact expiration date(s) relevant to Stelara in Europe. You can search Stelara here:

Are there also exclusivity rules in Europe besides patents?
Even after a patent expires, products may still have regulatory exclusivity (for example, under the EU’s rules around data and market protection). This means the “earliest generic/biosimilar entry date” in the EU can differ from the “latest patent expiry date,” depending on the combination of patent coverage and regulatory exclusivity.
Why you might see different dates for “Stelara patent expiration” online
Common reasons include:
- Different patents in the same family (substance vs. formulation vs. method-of-use).
- Country-by-country differences across the EU (some patents land in some countries and not others).
- Patent term adjustments/extension (when applicable) and court outcomes.
If you tell me the country, I can narrow it down
“EU” can mean different things in patent listings (e.g., EP filings across specific countries). If you share which country you care about (UK/EP member states like Germany, France, Spain, etc.) or whether you mean “first generic/biosimilar entry,” I can narrow the likely relevant timeline.
