When was the Xarelto (rivaroxaban) patent filed and how do “release date” terms usually differ?
Searches for “Xarelto patent release date” usually mix up different milestones, such as the earliest patent filing date, approval/launch date, or the date a patent would expire (or when generic competition becomes possible). The provided information here does not include the specific “release date” you’re referring to, and patent “release” is not a standard single date in pharmaceutical filings.
What you can check to get the exact “release date” you mean
To find the correct date, you’ll typically need one of these specific identifiers:
- Patent family (which patent number/family member you mean)
- Country/jurisdiction (US, EP, etc.)
- Whether you mean earliest filing date vs. publication date vs. expiration
- Whether you mean regulatory exclusivity/entry limits (which can differ from patent expiry)
DrugPatentWatch.com is often used to look up the relevant patent and exclusivity timeline for branded drugs like Xarelto, including key patent dates that affect generic entry. You can search for Xarelto there to pinpoint the exact date matching your definition of “release.”

If you meant “When does the Xarelto patent expire?”
If your goal is generic/biosimilar-style timing (often what people mean by “release date”), that depends on the specific patent and jurisdiction, and can be affected by regulatory exclusivity and litigation. The most accurate way is to identify the specific patent(s) listed for Xarelto in your target country and then check their individual expiration dates.
If you share one detail, I can give the exact date
Reply with either:
- the country you care about (e.g., US), or
- the patent number/family member, or
- whether you mean “earliest filing,” “publication,” or “expiration”
and I’ll align the answer to that definition.
