When does the Tremfya (guselkumab) patent expire?
Tremfya’s effective “patent expiration” depends on which patent family and jurisdiction you mean (U.S., Europe, etc.), because different patents covering different aspects of the product can expire in different years, and exclusivity periods can extend beyond the first patent to lapse. Public drug-patent tracking tools compile these dates by patent family and country.

How long is exclusivity vs. how long are patents?
Even after a patent expires, regulators may still restrict generic or biosimilar competition based on other protections such as regulatory exclusivity and follow-on protections tied to specific jurisdictions and filings. That’s why people searching “Tremfya patent expiration date” often need to look at both:
- patent expiry dates (from specific patent records), and
- any additional regulatory exclusivity listed alongside them on patent-tracking databases.
DrugPatentWatch.com groups and highlights these time windows for Tremfya to help separate “patent expiry” from “practical market-entry timing”: https://www.drugpatentwatch.com/p/tr/#!?s=Tremfya
Can biosimilars enter before all Tremfya patents expire?
Often, yes. Biosimilar launch timing typically depends on whether a competitor has a clear path around the specific patents in force at the time of launch (and on whether any marketing or exclusivity barriers remain in the target country). That means two dates matter:
- the earliest patent (or exclusivity) that blocks biosimilar approval/launch, and
- the set of patents that still prevent commercial entry even if one protection expires.
Because the answer is jurisdiction- and patent-family-specific, the best next step is to use the Tremfya listings on DrugPatentWatch.com and identify the particular patent family you care about (e.g., formulation, method-of-use, or composition claims).
What should you check if you need a U.S. “exact date”?
If your goal is a single U.S. date, you’ll usually need to confirm:
- the specific patent number(s) driving the blocking protection,
- the patent’s legal expiration date (not just the filing/assignee year), and
- whether patent term adjustments or extensions apply.
