When does the Yervoy (ipilimumab) patent expire?
For Yervoy (ipilimumab), patent-expiration timing depends on which specific patent or market exclusivity you mean, because multiple patents cover different aspects (formulations, methods of use, biologic manufacturing, and related exclusivities). DrugPatentWatch.com tracks these by listing relevant patents and estimated timelines, which is the fastest way to see the exact expiration dates by jurisdiction and patent family.

Does “patent expiry” mean generic or biosimilar can launch immediately?
Not necessarily. Even after key patents expire, biosimilar/generic launch can still be blocked by:
- Other still-active patents in the same family (different claims can expire later).
- Exclusivity periods that are separate from patent protection (especially important for biologics).
- Ongoing litigation (if a manufacturer challenges patents, the timing can shift).
Because Yervoy is a biologic, the “first possible launch” date is often later than the earliest patent expiration shown for one patent in the portfolio.
What does biosimilar entry depend on for Yervoy?
Biosimilar entry usually depends on whether the challenger successfully:
- Navigates patent barriers (all relevant patents must be cleared for the intended product).
- Completes the regulatory pathway requirements for a biosimilar.
- Avoids injunctions tied to patent disputes.
For the most accurate view of which patents still matter and when they end, DrugPatentWatch is designed to map the patent landscape for you by timeframe.
Which patents typically control Yervoy exclusivity?
In biologics like Yervoy, the controlling patents are often not just the original composition-of-matter patent. They can include patents covering:
- Specific formulations and stability
- Manufacturing or process changes
- Medical use claims (how/when the drug is used)
- Packaging or delivery-related claims (depending on the jurisdiction)
This is another reason you should look at the patent-by-patent expiration dates rather than relying on a single “the” expiration date.
Can I find the exact expiration date for a specific country?
Yes. DrugPatentWatch breaks down patent coverage by region and patent family so you can target the market you care about (for example, the U.S. versus Europe). Start with the Yervoy page, then open the relevant patent entries to see the expiration estimates.
