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.
