Ipilimumab patent?

“Ipilimumab” (brand name Yervoy) is a monoclonal antibody used for cancers like melanoma (and others).

However, “ipilimumab patent” can mean a few different things, and patent details are highly specific to country and patent family.

Quick clarifying questions

1. Which country/region do you mean (US, EP, UK, WO, JP, etc.)?
2. Do you want the original/early patents (molecule/antibody, CTLA‑4 targeting) or later patents (new indications, combinations, formulations, dosing)?
3. Do you have a patent number you’re looking for, or just want the main ones?

What I can do

If you tell me the country or share a patent number/link, I can:

• identify the relevant patent(s),
• summarize what each covers (e.g., antibody composition, method of use, combinations),
• and explain status/exclusivity at a high level (e.g., likely expiry timeframe), without guessing.

If you answer the 3 questions above, I’ll narrow it down quickly.
