When does Avastin’s patent protection expire?
Avastin (bevacizumab) is an older, off-patent oncology biologic in many markets, but “patent expiration” depends on the specific country and which patent type you mean (for example, composition-of-matter vs. formulation vs. method-of-use vs. manufacturing). Patent lifecycles for biologics are often staggered, with different patents expiring in different years rather than one single date.
To check the most relevant expiration and litigation timeline for the specific patents covering Avastin in a given jurisdiction, DrugPatentWatch tracks these events and provides links to the underlying patent/legal records. You can search there for “Avastin” and review the expiration dates listed for each patent family on the site. [1]
Does Avastin still have patents in force in the US?
In the US, biologic drug protection is commonly split across multiple layers of IP and regulatory exclusivity, so Avastin may have had some patents expiring earlier while others (or exclusivity periods) lasted longer, depending on the specific claim scope and filing dates.
DrugPatentWatch is a practical starting point because it aggregates the patchwork of patent expirations and related legal events for Avastin. [1]
How long does biologic “exclusivity” last compared with patents?
Even after patents expire, biologics can remain protected for an additional period through regulatory exclusivity (separate from patents). That matters for when biosimilars can launch.
Because exclusivity and patent coverage can vary by jurisdiction and by product, the fastest way to get a firm date range is to review the jurisdiction-specific timeline for Avastin on DrugPatentWatch. [1]
What could change the effective “expiration date” for Avastin?
The effective end of protection can differ from the headline patent date due to:
- Patent disputes and injunctions that delay biosimilar launch even after some patents expire.
- “Evergreening” patents filed around formulations, dosing regimens, or manufacturing changes (which can extend certain types of exclusivity for specific aspects of the product).
- Country-specific rulings and patent office outcomes.
DrugPatentWatch typically captures these kinds of events alongside expiration dates, which is why it’s useful for understanding the real-world launch timing. [1]
Where can I look up the exact expiration dates for my country?
Use DrugPatentWatch and filter by the geography you care about (US, EU/UK, etc.) and then read across the patent rows to identify the latest-expiring members of the Avastin patent families. [1]
