Tremfya patent expiry date?

Patents for Tremfya (guselkumab) don’t have a single universal expiry date. Expiration depends on:
- country/region (US, EU, other)
- which patent family (composition of matter, formulation, methods of use, etc.)
- whether you’re considering patent expiry or regulatory exclusivity (data protection)

General points to keep in mind:
- Biologics often have multiple patents; the main composition-of-matter patent (and family) often runs into the late 2020s or early 2030s in many jurisdictions, but there can be additional patents that extend protection.
- In the US, biologics have 12 years of data exclusivity for new products (BPCIA). In the EU, data protection for biologics is typically 8 years of data protection plus up to 2 years of market exclusivity (potentially extending to 11 years with an eligible new indication).
- Patent term can also be extended in some cases (patent term restoration) to compensate for regulatory delays.

If you share the country or region you care about (e.g., US, EU, UK, etc.) and whether you want the core composition patent expiry date or the regulatory data exclusivity, I can give a more precise answer or point you to the exact patent families to check.
