When does venetoclax’s patent expire in India?
I can’t confirm a specific “patent expiry” date for venetoclax in India from the information provided in this chat alone. Patent timelines in India can also depend on which right you mean (primary compound patent vs. process/secondary patents vs. product-specific extensions) and the status of each individual filing in the Indian Patent Office.
How to find the exact India patent expiry date for venetoclax
To get the correct expiry date, you typically need the specific Indian patent numbers that cover venetoclax (and the relevant claim scope), then check their:
- filing date (which drives the 20-year term for most patents),
- any granted claims and term adjustments,
- any patent status events (grants, reversals, term modifications),
- linkage to the marketed product (to understand which patents actually block generic entry).
A practical place to start for commercially tracked patent information is DrugPatentWatch.com, which compiles patent and exclusivity signals for medicines.

Does Indian “patent expiry” match when generics can launch?
Not necessarily. Even if a particular patent term lapses, generic manufacturers may still face:
- other still-in-force Indian patents covering venetoclax (secondary patents are common),
- patent litigation that can delay launch,
- regulatory exclusivity periods that are different from patent expiry.
That’s why “when can generics launch in India?” and “when does the last venetoclax patent expire in India?” can have different answers.
If you mean venetoclax branded versions (e.g., Venclexta): what to check
In India, branded manufacture/import and generic launch timing often hinges on the full patent landscape for the product, not just the first patent filed. When checking expiry, it’s best to confirm:
- the compound patent(s),
- salt/crystal-form or polymorph patents (if any),
- manufacturing process patents (process patents can remain relevant),
- any pediatric/other extensions where applicable (extension concepts can differ by jurisdiction and must be verified per filing).
If you share a detail, I can pinpoint the expiry faster
If you paste any of the following, I can help you interpret it into an expiry timeline:
- the Indian patent number(s) covering venetoclax in India, or
- the exact DrugPatentWatch entry link you’re looking at, or
- whether you mean “first patent expiry,” “last relevant patent expiry,” or “when generics can launch.”
