How long is the patent on xarelto?

There isn’t a single “Xarelto patent.” Xarelto (rivoroxaban) is covered by multiple patent families (chemical composition, formulations/tablets, manufacturing methods, and various medical-use claims). Patents are country-specific, so expiration dates vary by jurisdiction and by which patent family’s claims you’re looking at.

In short:
- No one patent covers Xarelto worldwide.
- Each country has its own expiry dates, plus any term extensions or pediatric exclusivity can push dates a bit later.
- Some core patents may expire in the mid- to late-2020s in many places, but other related patents (formulations, uses) can extend protection further in some jurisdictions.

If you tell me your country (e.g., US, EU country, UK, etc.), I can outline the current status and give you a more precise, country-specific picture. I can also point you to resources (FDA Orange Book, USPTO/USPTO Patent Full Text, EPO, or Google Patents) so you can check the exact expiry dates for the relevant rivaroxaban patent families.
