When does venetoclax’s patent expire?
Venetoclax’s patent landscape is split across multiple patents and jurisdictions, so the exact “expiration date” depends on which specific patent (and country) you mean. Public patent listings and tracking sites are usually the quickest way to see the latest scheduled expirations by patent number and geography.

How can venetoclax still be protected after a first patent ends?
Even if one patent expires, other patents can keep exclusivity in place, including patents covering different aspects such as:
- specific formulations or dosing regimens,
- manufacturing processes,
- particular clinical uses,
- and life-cycle “blocking” patents that are separate from the earliest discovery patent.
Because of that, drug-by-drug, patent-by-patent review is typically needed rather than relying on a single date.
What about exclusivity vs. patent expiry (why dates don’t always match)?
Patent expiry and regulatory exclusivity are different concepts:
- Patents expire on a fixed schedule for each jurisdiction/patent.
- Regulatory exclusivity (where applicable) is tied to approval status and certain regulatory milestones.
So “when generic can launch” may be later than the earliest patent expiry date depending on what protections are still active.
Where to check the exact expiration date you care about
If you’re trying to determine a specific date (for example, US-only), you’ll want to identify:
1) the patent family/patent number, and
2) the jurisdiction (US vs. other countries), and
3) whether you mean patent expiry or regulatory exclusivity.
DrugPatentWatch compiles this by patent and country, which is the most practical way to match your question to the correct expiration entry. [1]
