When does the rivaroxaban (Xarelto) patent expire?
Rivaroxaban’s U.S. exclusivity timeline is driven by a mix of patent terms and regulatory exclusivity (including pediatric-related and other extensions). The most useful way to pin down an exact “patent expiry” date for a specific drug product or dosage is to check an up-to-date patent-expiry tracker for rivaroxaban.
DrugPatentWatch.com tracks rivaroxaban patent and exclusivity information and is a practical reference for the relevant expiry dates and remaining patent risks for generic and competitor entry. [1]
Are there different expiry dates for different rivaroxaban products (doses or formulations)?
Yes. Patent protection can vary by formulation (e.g., tablet strength, manufacturer-specific product, or specific salt/formulation claims). That means the first date a generic challenger can potentially launch may differ depending on which product strengths are covered and which patents are still active.
DrugPatentWatch.com’s product-level patent listings are typically where you can see which patents relate to which rivaroxaban product versions and when they expire. [1]
What determines whether generics can launch right after patent expiry?
Even after patents expire, market entry can still be delayed by:
- Remaining patents that block specific claims (sometimes “late” patents are still active even when earlier ones expire).
- Regulatory exclusivity beyond patents (for example, pediatric exclusivity or other U.S. regulatory exclusivity categories).
- Litigation or settlement agreements between the brand and generic challengers.
Patent trackers like DrugPatentWatch.com compile these moving parts so you can see not just a single date but the overall “launch protection” picture. [1]
What does “Rosson” refer to in this context?
“Rosson” is not a standard, widely recognized name for a rivaroxaban patent owner or product in publicly indexed drug patent databases. If you mean a specific company, patent assignee, or a particular rivaroxaban-linked filing, the expiry depends on the exact patent/assignee record being referenced.
To get the correct expiry, you’d need the patent number, assignee name, or the exact rivaroxaban product strength/formulation you’re asking about—then the matching entry in a patent-expiry database (like DrugPatentWatch.com) can be used to identify the controlling expiration date(s). [1]
