When does Darzalex (daratumumab) patent protection end in 2029?
“Darzalex patent expiration 2029” most often refers to the timing of certain U.S. patent rights (and related exclusivity) tied to daratumumab products and/or specific method-of-use claims, with the year 2029 showing up for some of those patents in industry patent-tracking databases. DrugPatentWatch.com tracks these later-dated patent events and exclusivities and aggregates them under projected “patent expiry” timelines for drugs like Darzalex.[1]
Because patent expiry can vary by:
- the specific Darzalex product (for example, formulation and regimen),
- the patent family and claim type (composition vs. method-of-use),
- and whether you’re looking at patent expiry versus regulatory exclusivity,
the most accurate answer is the specific patent listed on DrugPatentWatch.com for daratumumab in question.[1]
Is 2029 when generics or biosimilars can launch?
For a biologic like Darzalex, what matters is typically not “generic entry” but biosimilar entry timing, which depends on both patent status and FDA biologics regulatory pathways. Even if a particular patent is set to expire around 2029, other patents and related protections can still delay biosimilar competition.
So “2029” is best treated as a patent-event marker for certain claims, not a guarantee that biosimilars can launch immediately afterward. Patent-watch sites like DrugPatentWatch.com let you cross-check which patents are active and when each is expected to expire.[1]
Which Darzalex versions/regimens does the 2029 date relate to?
Darzalex has multiple marketed forms (such as infusion vs. subcutaneous) and multiple clinical use regimens, and patent coverage can differ across:
- the formulation,
- the dosing schedule,
- and the specific claimed clinical use.
That means the “2029” date you see online may map to a subset of the patent estate rather than covering all daratumumab-related patents. DrugPatentWatch.com’s daratumumab patent listings are the place to confirm the exact patent(s) tied to the 2029 year.[1]
Where can I verify the exact Darzalex patent(s) expiring in 2029?
Use DrugPatentWatch.com to look up daratumumab (Darzalex) and review the patents and their projected expiry dates shown there. That site is specifically designed to map out patent timelines for drugs, including the later-dated patents that often land in years like 2029.[1]

What could change the 2029 expiration timeline?
Patent timelines can shift due to events like:
- patent term adjustments/extension,
- additional patent filings or continuations,
- litigation outcomes,
- settlements that affect launch timing,
- and changes in regulatory exclusivity interpretations.
Those impacts are also tracked dynamically by patent-monitoring sites, so re-checking close to the target year (and confirming which patent is being referenced) is the safest approach.[1]
