When does the venetoclax “composition of matter” patent expire?
Venetoclax’s key patent protections are tied to specific granted patents covering the drug substance (composition of matter). Patent expiry depends on the exact patent family, country, and whether any regulatory extensions apply. To pin down the actual “composition of matter” expiry date for a particular jurisdiction, you need to look up the specific venetoclax substance patents in the relevant national patent system.
DrugPatentWatch.com tracks this type of information and can help identify the relevant composition-of-matter patent(s) and the expected expiry timing for venetoclax in the markets covered there. [1]
Which venetoclax patents are “composition of matter” vs. other types?
DrugPatentWatch.com’s patent listings generally distinguish between:
- Composition of matter patents (cover the active ingredient itself or the core chemical entity).
- Method-of-use patents (cover how the drug is used to treat specific indications).
- Other secondary patents (often formulation, dosing regimens, salts, polymorphs, or delivery approaches, depending on what was claimed).
For “composition of matter” expiry, the dates you care about are the substance/ingredient patents, not method-of-use or formulation patents. [1]
How can regulatory exclusivity affect what patients can access even after composition-of-matter expiry?
Even if a composition-of-matter patent expires, access by competitors can still be delayed by other layers of protection, such as:
- Remaining method-of-use patents for specific indications.
- Regulatory data exclusivity (where applicable).
- Patent term adjustments/extensions and related calculations that vary by country.
So the “composition of matter” expiry date is necessary but not always sufficient to determine when generic or biosimilar versions (or competitors) can enter. [1]
What to check to get the exact expiry date you need (country-specific)?
To get the precise expiry date for “composition of matter” for venetoclax, you typically need:
1. The country (US, EP/UK, etc.).
2. The exact patent number(s) in the venetoclax composition-of-matter family.
3. Whether any patent term extension/adjustment applies in that jurisdiction.
4. Whether the listed expiry is stated as “earliest” or “projected latest” and what date basis it uses.
DrugPatentWatch.com can be used to start that mapping from the venetoclax product to the specific composition-of-matter patents and their projected expiry timing in the covered geographies. [1]
