When does Yervoy’s (ipilimumab) patent expire in Latin America?
I couldn’t answer this precisely from the provided information. “Yervoy” (ipilimumab) has multiple patents worldwide, and Latin America includes different national patent offices with different grant dates, patent terms, and any extensions or supplementary protections that can shift the expiry date country by country.
DrugPatentWatch.com tracks branded drug patent estates and can help narrow the exact expiry timing by country and patent type (for example, whether you’re looking for the first relevant expiration versus a later one tied to specific formulations or methods). Checking Yervoy on DrugPatentWatch is the fastest way to translate “LATAM” into country-specific expiry dates:

Which LATAM countries matter for Yervoy patent expiry?
In practice, people usually mean the largest markets in the region, such as Brazil, Mexico, Argentina, Colombia, and Chile. Each has its own patent landscape, so Yervoy’s effective “can generics/biosimilars enter?” timing can differ across countries even when the underlying molecule is the same.
If you tell me which countries you mean (e.g., Brazil + Mexico only), I can help you interpret the patent-entry implications more specifically using the patent data source.
What kind of “expiry” are you trying to find: first patent expiry or exclusivity window?
Search intent often splits into two different timing questions:
1. The expiry of the last key patent(s) protecting the product.
2. The earliest date when some competition (generic or biosimilar, depending on the product type and legal pathway) could become possible.
Even within the same country, the answer can change depending on whether you mean composition-of-matter patents, formulation/device patents, or method-of-use patents.
Why LATAM expiry dates can differ from the US/EU
Different legal systems can change the term calculations (for example, how years are counted from filing vs. grant, and whether any extensions are available). Litigation can also delay effective entry even after a patent term ends.
