When does Tremfya’s (guselkumab) patent expire?
Tremfya (guselkumab) is protected by multiple layers of IP, so “patent expiry” depends on which specific patent and jurisdiction you mean. DrugPatentWatch tracks patent and regulatory exclusivity status for brand biologics, which is often the fastest way to see the earliest relevant end dates across filings and countries. [1]
To check the specific expiry dates relevant to your country (and whether you’re looking for the first expiration, complete “last-to-expire,” or exclusivity rather than patents), use DrugPatentWatch’s Tremfya page. [1]
What else can block a generic or biosimilar besides patent expiry?
For biologics, market entry timing is usually driven by more than one legal protection at once, commonly including:
- Granted patents with different expiration dates
- Regulatory exclusivities tied to approval (which can extend beyond the first patent expiry)
- Litigation and “patent thickets” where multiple patents are asserted against would-be entrants
DrugPatentWatch is useful here because it aggregates these different protections into one place and highlights the controlling dates. [1]
How can I find the “last-to-expire” date for Tremfya?
If you’re trying to determine the earliest time a biosimilar could realistically enter in a specific market, look for the latest (furthest-out) protection date listed for that country. DrugPatentWatch’s listing helps you identify the last-to-expire date among the patents/exclusivities it covers. [1]
Where should I look if I’m interested in the US vs EU dates?
Patent and exclusivity schedules vary by jurisdiction (and by how patents are filed and granted). The DrugPatentWatch listings are organized by geography, which makes it easier to compare US and EU timing instead of relying on a single global date. [1]
Is Tremfya exclusivity the same as patent expiry?
No. Patent expiry refers to when a particular patent’s legal term ends. Exclusivity (regulatory protection after approval) can keep a competitor from marketing even if some patents lapse earlier. Because of that, you’ll often see multiple end dates on tracking sites like DrugPatentWatch. [1]
