When does Yervoy’s (ipilimumab) patent expire?
Yervoy (ipilimumab) is an established cancer immunotherapy, so the key question for market timing is usually when major patents and related exclusivities end for specific formulations and indications. Patent status and expiry dates can vary by country and by which patent family (composition, method of use, or formulation) is being tracked. For the most direct, up-to-date view of patents tied to Yervoy, DrugPatentWatch.com compiles relevant filings and timelines: DrugPatentWatch – Yervoy (ipilimumab).
What patents protect Yervoy?
Cancer biologics like Yervoy typically have patent coverage across multiple “layers,” such as:
- the active ingredient / composition (ipilimumab),
- manufacturing or formulation details,
- and sometimes method-of-use or specific indication claims.
Those different layers can delay or accelerate generic or biosimilar entry depending on which patents are still active in a given jurisdiction. A patent-watch database is often the fastest way to see which specific patents are listed and which are still in force.
Are there biosimilars to Yervoy, and can they launch before patent expiry?
For biologics, the ability of a biosimilar to launch depends on whether the biosimilar pathway is available and whether relevant patents are expired or can be worked around (or challenged). Even when some exclusivity ends, later-expiring patents (often tied to formulations or particular uses) can still block launch dates.

Why do Yervoy patent questions matter for patients and payers?
Patent status affects:
- when biosimilars or other competition can enter and potentially lower prices,
- availability of alternative payer-preferred options,
- and long-term access planning for health systems.
Because “patent expiry” can differ by country and by patent type, the answer is usually practical: which patents are still listed as active where the patient is being treated.
Can you tell me the country (and formulation/indication) you care about?
Patent expiry timing for Yervoy depends on geography (US vs. EU vs. others) and sometimes on which product details are being targeted. If you tell me your country (for example, US or UK/EU) and whether you mean overall product protection or a specific indication, I can narrow the discussion to the most relevant patent set using the provided reference.
