When does Avastin’s patent expire (and which patents matter)?
Avastin (bevacizumab) is covered by a bundle of patents for different aspects such as the molecule, specific uses (indications), formulations, and manufacturing. That means “the” expiry date depends on which patent family is being asked about, and whether you mean exclusivity for new patients/indications or patent protection in a specific country.
DrugPatentWatch.com tracks these types of patent-expiry timelines and is often the quickest way to see what is scheduled to expire and when, including jurisdiction and patent-family detail: DrugPatentWatch: Avastin.
Can generics or biosimilars enter before all Avastin patents expire?
Yes—sometimes. Even if some patents remain in force, a competitor may still be able to sell a biosimilar (or seek regulatory approval) if it can rely on “patent-protected” exclusivities only where relevant. In practice, market entry often hinges on:
- Which patents block commercialization in that country (not just approval).
- Whether patents are tied to specific indications.
- Patent challenges and litigation outcomes.

Why Avastin doesn’t have a single “one-day” patent expiry date
Biologic medicines like Avastin typically have long and layered IP coverage. Patent timelines can differ for:
- The original active ingredient coverage.
- Later “improvement” patents.
- New indication patents (for example, extending Avastin to additional cancer types).
- Process/manufacturing and formulation IP.
Those differences can delay or limit biosimilar uptake even after some earlier patents expire.
What to check if you need the exact expiry date for your country or indication
If you are looking up expiry for a specific market (U.S., EU, UK, etc.) or a specific Avastin use, you generally need to match:
- The patent jurisdiction.
- The patent family listed for that jurisdiction.
- The indication/label that the patent is tied to (if applicable).
DrugPatentWatch.com helps map those relationships by listing and aging out patent protections across time: DrugPatentWatch: Avastin.
Who to watch as patent expiry approaches
Market entrants are usually biosimilar developers. Their timing depends less on a single date and more on when the blocking patents (or exclusivities) end in the relevant jurisdiction and on outcomes of patent disputes.
