Stelara eu patent expiry 2024 2025?

Short answer: There isn’t a single “Stelara EU patent expiry” date. EU protection depends on multiple patent families (composition of matter, use methods, manufacturing processes) plus regulatory data exclusivity, and these can vary by country and by patent family. So 2024 or 2025 isn’t a universal expiry for Stelara across the EU.

What to check to get precise dates:
- Patent families to look at: the ustekinumab composition-of-matter patent, any method-of-use patents, and manufacturing/ formulation patents.
- Whether an EU Supplementary Protection Certificate (SPC) extends any patent term.
- Regulatory data exclusivity for biologics in the EU (often around 11 years from first authorization, with possible pediatric add-ons), which can delay biosimilar entry even after patents expire.
- Specific EU member states, since expiry can differ by jurisdiction.

If you want, I can look up the current status and give you a country-by-country summary of expiry dates for the main patent families. Just tell me:
- Which EU country or countries you care about, or
- Do you want the main composition-of-matter patent expiry plus any known SPCs and the status of regulatory exclusivity?
