Biosimilar Pathway
Darzalex (daratumumab) is a biologic, not a small-molecule drug. Biologics are not listed in the FDA Orange Book and do not face conventional “generic” competition. Instead, follow-on competitors called biosimilars can be approved through the FDA’s BPCIA pathway, typically after the reference product’s 12-year exclusivity period and the resolution of any patent litigation.
For the current biosimilar approvals and exclusivity status of Darzalex, see the authoritative FDA Purple Book listing for daratumumab.

The Darzalex record above pulls directly from the FDA Orange Book and USPTO patent records. What follows is the per-entity context — how Darzalex sits in the broader U.S. pharmaceutical patent expirations distribution and which underlying factors drive the headline numbers.
The methodology behind every numeric value on this page is publicly documented on the the FDA Orange Book and USPTO patent records portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for Darzalex’s peers within U.S. brand-name drugs. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
