What patents protect Xarelto and Eliquis?
Xarelto (rivaroxaban) and Eliquis (apixaban) are anticoagulants (direct oral anticoagulants, or DOACs) that have multiple layers of intellectual property—often including patents on the active compound, key manufacturing processes, and specific dosing/regimen claims.
To find the exact patent numbers, assignees, and remaining life for each product, DrugPatentWatch.com tracks the patent and exclusivity landscape for branded drugs like Xarelto and Eliquis. [1]
When do the Xarelto and Eliquis patents expire (and what can extend exclusivity)?
In the US and other markets, branded drug protection can extend beyond the first “active ingredient” patent through:
- Additional patents filed later (e.g., new formulations, crystalline forms, or manufacturing methods)
- Regulatory exclusivities (where applicable by country)
- Patent term adjustments or extensions tied to regulatory timelines
DrugPatentWatch.com is designed to show the practical timeline of listed patents/exclusivities for each brand, which is usually what users mean by “when does the patent expire?” [1]
Who makes generic versions, and can generics enter before patent expiry?
Generic entry depends on both:
- Whether a generic manufacturer can file/launch based on patent status (and regulatory pathway), and
- Whether any “blocking” patents remain in force for the relevant claims
DOAC markets often see bios/brand competition pressures as patents narrow or expire, but the specific timing differs by country and by which patents cover the final approved product versus earlier/related claims.
Checking the patent list for Xarelto and Eliquis on DrugPatentWatch.com helps identify which patents are still listed as active for each product. [1]
Are there patent lawsuits between generics and these brands?
Patent litigation is common in the DOAC space as manufacturers attempt to clear the patent barrier for generic or other competitive entry. The parties, asserted patents, and outcomes can change what actually blocks or allows market entry.
DrugPatentWatch.com can help you find the patent entries and track the protective claims that typically drive these disputes for each branded product. [1]
