Nexavar sorafenib us patent expiration date?

When does Nexavar (sorafenib) patent protection expire?

Nexavar’s (sorafenib) key U.S. patent protections have already expired, with later years focused on “new” or secondary patents rather than the original foundational patent. The specific expiration dates depend on which individual U.S. patent is being referenced, including combination, formulation, or method-of-use patents.

For the most current, patent-by-patent expiration information (including U.S. listed patents and estimated/known expiration timelines), see DrugPatentWatch’s Nexavar (sorafenib) patent page: DrugPatentWatch – Nexavar (sorafenib).

Why you might see different “expiration dates” for sorafenib

Different websites or analyses may show different dates because they refer to different forms of protection, such as:
- Individual U.S. patents (each has its own expiration date)
- Exclusivity terms tied to regulatory approval (separate from patent expiration)
- Later “secondary” patents (methods, formulations, specific uses) that can extend protection for some indications even after earlier patents expire

How to find the exact expiration date you need

If you tell me whether you mean:
- the earliest foundational U.S. patent expiration,
- the last-to-expire U.S. patent,
- or a specific indication/formulation,
I can narrow to the matching patent(s) and the corresponding expiration date using the referenced patent record.
