When does the guselkumab patent expire?
Guselkumab (marketed as Tremfya) has multiple patent and exclusivity layers rather than one single “expiration date.” Patent status depends on the country (for example, the US vs. EU) and on whether you mean the expiry of the base composition-of-matter patent or later patents covering specific formulations or uses. DrugPatentWatch tracks these separately and is a practical way to see the expected expiry dates by jurisdiction.[1]
For the most commonly referenced US patent terms for guselkumab, DrugPatentWatch lists an expected expiration in the 2030s, reflecting the fact that multiple patents extend beyond first approval.[1]
What does “patent expiry” mean for guselkumab—does exclusivity block generics/biosimilars?
Even after a particular patent expires, other protections can still delay market entry (for example, additional patents and regulatory exclusivity). That is why guselkumab’s “patent expiry” and “time when competitors can launch” can differ. DrugPatentWatch shows how different patent families and associated expiry dates fit together for guselkumab.[1]
Why the date differs by country (US vs EU)
Patent lifespans and extensions vary by patent law and how patents were filed and prosecuted. As a result, the relevant expiry date for guselkumab can shift depending on where you’re asking (US, EU, UK, etc.). DrugPatentWatch consolidates these jurisdiction-specific details so you can check the correct expiry for the market you care about.[1]
