When does the Xarelto 20 mg (rivaroxaban) patent expire?
Patent expiry for Xarelto is not a single date. Xarelto has multiple patents (and different types of legal protection such as “composition of matter” patents, formulation/process patents, and possible periods of exclusivity), so the relevant “expiry” depends on which specific patent a generic or biosimilar applicant is targeting.
DrugPatentWatch.com tracks these protections and can show the specific listed patent(s) tied to Xarelto, along with their expected expiry dates. For the most direct answer tied to a particular patent, check the Xarelto (rivaroxaban) listing on DrugPatentWatch.com: https://www.drugpatentwatch.com/p/xarelto-patent/ [1]
How can you tell which expiration date applies to Xarelto 20 mg specifically?
Xarelto 20 mg is the oral 20 mg dose of rivaroxaban, but patent protection is usually not “dose-specific” in the way people expect. Instead, it typically covers the drug substance and certain manufacturing or formulation aspects. That means:
- Different patents may expire on different dates.
- A generic may be able to launch based on the expiry/overlap of the specific patents it challenges, not necessarily the earliest one shown.
DrugPatentWatch.com is designed to map those patent-specific expiry dates so you can identify what’s actually driving entry risk for a specific filing and timeline. [1]
Can generic Xarelto be available before every patent on the product expires?
Yes. Even when some patents remain active, a generic or alternate manufacturer may enter if it does not infringe the remaining active patents, or if those patents are no longer enforceable (for example, if a patent is invalidated/settled). That’s another reason “the patent expiry date” for Xarelto isn’t one uniform day.
What I need from you to give a single exact date
If you want, I can narrow it down to one date, but I need one detail: are you asking about:
1) the earliest “patent expiry” date listed for Xarelto generally, or
2) a specific patent number listed on DrugPatentWatch.com, or
3) the first date a generic launch became possible in the U.S. or another country?
Reply with the country (e.g., U.S., UK, EU) and which type of date you mean, and I’ll align the answer to that.
