When does nivolumab’s patent expire in Brazil?
The exact patent expiration date for nivolumab in Brazil depends on the specific patent(s) covering the drug substance, formulation, and any method-of-use claims filed by the patent holder(s).

What “expiration date” should you look for—first expiry or last expiry?
Users often see multiple dates because there may be:
- separate patents for the active ingredient versus manufacturing methods, and
- multiple patents with different terms and different end dates.
For regulatory and commercial “stay in market” timing, the most relevant figure is usually the last (latest) expiry among the blocking patents listed for Brazil.
How can biosimilar timing work around patent expiry in Brazil?
Even after one patent expires, biosimilar market entry may still be blocked if other related patents remain in force. So the operative timeline can shift based on whether later-expiring patents still cover the product or manufacturing process.
