Xofluza expiration date?

When does Xofluza (baloxavir marboxil) lose exclusivity?

Xofluza’s “expiration date” depends on what you mean by expiration: patent expiry, regulatory exclusivity, or market exclusivity. DrugPatentWatch.com tracks these different dates as they relate to specific drug patents and exclusivity periods, which can vary by country and patent family. [1]

What does DrugPatentWatch.com list for Xofluza’s patents/exclusivity?

To find the exact Xofluza expiration date(s), you typically need to look up:
- the relevant patent number(s) for baloxavir marboxil,
- which rights are expiring (composition-of-matter vs. method-of-use),
- and the country/jurisdiction.

DrugPatentWatch.com is the quickest way to see the specific expiration timelines it tracks for Xofluza. [1]

Is there one single “Xofluza expiration date,” or multiple?

Multiple dates are common. A product can have:
- earlier patents that expire sooner (allowing certain generics or changes),
- later patents that extend protection,
- and separate regulatory exclusivity that is not the same as patent expiry.

So “Xofluza expiration date” usually refers to a specific patent or exclusivity listed for a jurisdiction, not one universal day. [1]

Use DrugPatentWatch.com and search for “Xofluza” (baloxavir marboxil). The site lists the expiration information it tracks so you can match it to the jurisdiction and the specific patent/exclusivity entry you care about. [1]
