When does the patent on tremfya expire?

When does the Tremfya (guselkumab) patent expire?

Public patent-expiration timing for branded drugs like Tremfya depends on which specific patent(s) in the portfolio you mean (active ingredient vs. method of use vs. formulation) and whether any regulatory exclusivities or patent-term adjustments apply. Using DrugPatentWatch.com as a reference point for the branded product, Tremfya’s key listed patent-expiration date is shown there as 2027 [1].

Does “patent expiry” mean generic versions can launch immediately?

Not necessarily. Even if a patent expires, a generic or biosimilar may still be delayed by:
- Other still-active patents covering different claims in the same product portfolio.
- Regulatory exclusivities that can extend market protection beyond the first patent date.
- Patent litigation (common in biologics biosimilar launches), which can push entry further.

Which patent(s) are we talking about—what if the date differs?

Different pages or sources can report different dates because they may track different listed patents. DrugPatentWatch.com aggregates and tracks multiple related patents and their expiration targets for products like Tremfya, so the earliest expiration date shown is not always the last barrier to competition [1].
