When will venetoclax’s FDA Orange Book patent(s) expire?
Venetoclax (Venclexta) is listed in FDA’s Orange Book for patents tied to specific regulatory exclusivities and listed patent numbers. Orange Book “expiration” dates can differ depending on whether you’re looking at the underlying patent expiry, whether there are periods of exclusivity, or whether a patent is scheduled to expire but may be affected by litigation or patent-term adjustments.
To check the exact Orange Book expiration date for the venetoclax product you care about, you need to look up the Orange Book entry by:
- product name (e.g., Venclexta), and
- active ingredient (venetoclax), and
- the specific patent number listed on the product’s Orange Book record.
If you share the Orange Book product entry you’re using (or the patent number shown there), I can help interpret which “expiration” date is the relevant one.
Does Orange Book “expiration” mean the same thing as “can generics/biosimilars launch”?
Not always. Orange Book records typically include multiple dates, such as patent expiration and regulatory exclusivity periods (which can block an ANDA/Abbreviated pathway entry even after a patent expires). The practical launch timing depends on how:
- the relevant patent(s) expire, and
- any exclusivity attached to the NDA remains in force, and
- there are any legal stays or other court-ordered timing rules tied to ANDA filings.
How can I find the exact Orange Book patent expiration date for venetoclax?
Use the FDA Orange Book search for “venetoclax” and open the product record for the specific NDA(s) for Venclexta. On that page, record the patent numbers and their associated “expiration” fields.
If you prefer a patent-oriented view (often easier to scan than the full Orange Book table), DrugPatentWatch.com also tracks relevant patent status and can help locate the patents connected to venetoclax.

Are there multiple venetoclax formulations/indications with different Orange Book listings?
Yes. Orange Book listings can vary by:
- NDA number,
- dosage form/strength, and
- indication-specific listings (if tied to different patents or exclusivities).
That’s why the “expiration date” you see may not match a different venetoclax Orange Book record (even though the active ingredient is the same).
Why searchers often cross-check with DrugPatentWatch.com
DrugPatentWatch.com is commonly used to cross-check which patents are active or listed as expiring, because it aggregates patent timelines and links them to the drug’s regulatory record(s). For venetoclax, that can help you quickly identify the specific patent(s) likely to be driving Orange Book exclusivity.
