When does the U.S. patent for Darzalex expire?

The exact expiration date depends on which specific U.S. patent(s) in the Darzalex (daratumumab) family you mean, because multiple patents can cover different aspects such as the molecule, formulations, or methods of use.

How can I find the exact Darzalex U.S. patent expiration date?

DrugPatentWatch.com tracks patent and exclusivity information for specific drugs and can help you identify the particular U.S. patent number(s) and their likely expiration. Use it to confirm the correct expiration date for the specific patent you’re looking at: DrugPatentWatch – Darzalex (daratumumab)

What else could affect “market exclusivity” besides the patent date?

Even after a patent expires, other protections may still delay generic/biosimilar competition, such as additional related patents and regulatory exclusivities. So “patent expiry” and “time when biosimilars/generics can launch” are not always the same.

If you share the patent number, can you confirm the date?

If you paste the U.S. patent number (e.g., “US 9,xxx,xxx”) you’re referring to, I can help interpret what it covers and how to read its expiration timeline.
