Bevacizumab patent expiration date?

See the DrugPatentWatch profile for Bevacizumab

When does bevacizumab’s patent protection expire?

Bevacizumab (Avastin) is protected by multiple patents covering different aspects of the product (formulation, delivery, new uses, manufacturing, and process claims). That means there is rarely a single “the” expiration date for the drug; expiry dates vary by jurisdiction and by which specific patent is being referenced.

Because of the multiple patent families involved, the most reliable way to pin down an expiration date for a particular market (for example, the U.S. or EU) is to look up the specific listed patents and their individual expiration terms. DrugPatentWatch.com tracks these patent timelines and is a common starting point for identifying the relevant expiry date(s): DrugPatentWatch – bevacizumab/Avastin patents.

What determines the exact expiration date you’ll see?

The “patent expiration date” depends on which term you’re asking about:
- The original patent’s scheduled expiration (based on filing/priority dates and statutory rules).
- Patent term adjustments or extensions (in some jurisdictions).
- Patent “linkage” to specific approvals and label indications.
- Whether additional patents keep parts of the product or uses protected after earlier patents end.

Those factors can make one patent family expire, while another still blocks generic or biosimilar launch for a portion of protection.

Does the U.S. have a single expiration date for Avastin?

In practice, the U.S. timeline is usually described as a set of expiring patents (and sometimes other exclusivities), not one date. If you’re trying to estimate when a biosimilar can enter (rather than simply when the first patent expires), you need to match the patent list to the approved reference product and the biosimilar’s development strategy.

Which market do you mean (U.S., EU, UK, etc.)?

If you tell me the country/region you care about, I can narrow the answer to the relevant patent expiry schedule for that market and point to the specific patents that drive the last-not-expired protection.

AI-Drug Label Prescribing Information Alignment Report

Patient Risk: Low

Summary

The AI-generated statements concern patent/market-exclusivity timing and do not provide claims about FDA-approved prescribing information (indications, dosing, contraindications, warnings, drug interactions, adverse reactions, or administration). Therefore, label alignment cannot be evaluated from the provided content.


Category Scores


Accurate Statements


Unsupported Statements

All statements about patents, patent expiration dates, jurisdictional variation, how to look up patents, and references to a specific patent-tracking website (DrugPatentWatch.com) as a starting point for expiry dates.
Not supported or contradicted by the supplied FDA prescribing information excerpts, because the label excerpts provided relate to clinical use, dosing, safety, and administration—not patent expiration timelines or patent landscape details.
Statements that biosimilar entry timing depends on matching patent lists to the approved reference product and biosimilar development strategy, and that the timeline is usually described as expiring patents and sometimes other exclusivities rather than one date.
Not supported or contradicted by the supplied FDA prescribing information excerpts; the excerpts contain no information about biosimilar entry timing, patent linkage, or exclusivity frameworks.
