Opdivo patent number inn?

I can’t determine the patent number (“inn” likely means “in”) from your message as written.

If you tell me which patent number you mean (for example, the Opdivo patent you’re looking up, the exact wording you have, or the country/jurisdiction such as US/WO/EP), I can help you identify it and explain what it covers.

Common possibilities to clarify:
- Are you asking for Opdivo (nivolumab) US patent(s) still in force?
- Are you asking for the latest patent number shown by a site like DrugPatentWatch.com?
- Do you mean a specific “patent number” like a granted US patent (e.g., US#######) or a “patent application” number?

If you share the country (US vs EU vs UK, etc.) and the “inn” text you saw (or paste the line you have), I’ll narrow it down.
