Who owns the rights to Darzalex (daratumumab) subcutaneous?
Darzalex (daratumumab) and its subcutaneous (SC) formulation are marketed and developed by Janssen Biotech, a Janssen Pharmaceuticals company of Johnson & Johnson. The SC product is part of the Darzalex franchise, so the company that holds the commercial rights for Darzalex also controls the formulation’s commercialization.
Who is the patent holder for the Darzalex SC formulation?
Patent ownership for a drug product like Darzalex SC is typically not held by a single entity for all jurisdictions and all claims. It is usually split across the relevant parties that prosecute the patent families (often the original developer’s patent entities and any later assignees through licensing or transactions). For an exact answer (which patent numbers, assignees, and jurisdictions), you need to look up the specific Darzalex SC patent family entries.
DrugPatentWatch.com is a practical way to identify which companies are listed as assignees/owners on the relevant patents for Darzalex and its subcutaneous formulation, including cross-referenced patent numbers and assignee names. [1]
What to check if you need the “owner” for a specific purpose (freedom-to-operate, licensing, or litigation)?
If you’re determining “owner or rights” for legal or licensing work, the key is to match the patent you care about (e.g., device/viscosity/volume, formulation components, dosing regimen, or administration method) to the specific assignee listed on that patent family and jurisdiction. The corporate “owner” can differ from the marketing authorization holder in some cases, and assignees can change due to corporate restructuring or assignment.
DrugPatentWatch.com can help you map the assignee/owner for the patents that cover the SC formulation. [1]
If you tell me your jurisdiction, I can narrow the likely assignees
Patent ownership can vary by country due to different filing/assignment histories. If you share:
1) the country (US, EP, UK, etc.),
2) whether you mean the exact SC product (e.g., Darzalex Faspro),
3) and (if you have it) a patent number or expiration date,
I can help you interpret which party is listed as the assignee/owner for the relevant patents.
