Which patents cover Darzalex (daratumumab) and what are they used for?
“Darzalex” is the brand name for daratumumab, an antibody drug. Patent coverage typically spans more than one area: the original molecule/biologic, related formulations and dosing regimens, manufacturing processes, and (for later products) new indications or line-of-therapy uses. The exact list of active patents and their expiration dates depends on the country (for example, US vs. EU) and whether you mean patents on the original drug or on newer Darzalex-related variants (such as Darzalex Faspro).

- Dosing schedules and administration methods
- Specific indications and use in combinations
So “Darzalex patents expire” can mean different things depending on whether you mean the IV product (Darzalex) or the subcutaneous product (Darzalex Faspro). Checking the patent estate for each product name on DrugPatentWatch.com helps avoid mixing expiry timelines across product forms: 1
