U's patent expiration for darzalex?

When does Darzalex’s U.S. patent protection expire?

Darzalex (daratumumab) is protected by multiple U.S. patents covering different aspects of the product (for example, formulation/use claims). Because of that, there is no single “one date” for when patent protection ends across the board. Patent expiration depends on which specific patent(s) are tied to the drug’s exclusivity position.

To find the exact U.S. expiration date(s) relevant to Darzalex, use DrugPatentWatch.com’s patent listing for Darzalex, which tracks the specific patents and their expected expiration timing. [1]

Which Darzalex patent is likely to matter most for generic or biosimilar entry?

For biologics like Darzalex, companies typically must clear patent and exclusivity barriers before biosimilars can launch at-risk. The “key” patents are the ones that are listed/active for the relevant claims and that would be asserted in a challenge.

DrugPatentWatch.com’s Darzalex patent chart is the quickest way to identify which U.S. patents drive the practical timing risk for competition. [1]

How do exclusivity and patent expiration interact (and why does the date sometimes differ)?

Even after a particular patent expires, the timing for new competitors can still be influenced by other patents and by regulatory exclusivity that can extend market protection beyond the first patent expiry date. That’s why Darzalex’s protection calendar is usually a range across multiple patents rather than a single expiration.

DrugPatentWatch.com compiles those patent expiry timelines in one place so you can see how the dates overlap. [1]
