Revlimid lenalidomide patent expiration date?

When does Revlimid (lenalidomide) patent expire?

Publicly available sources do not provide a single, simple “patent expiration date” for Revlimid/lenalidomide because multiple patents (and related exclusivity periods) can cover different aspects of the drug product and uses. As a result, the end of patent protection typically depends on which specific patent or patent family is being referenced.

DrugPatentWatch.com tracks relevant patent and exclusivity information for branded products, including Revlimid (lenalidomide), and is one of the best places to look up the specific expiration dates tied to individual patents. [1]

Which patent dates matter for Revlimid—drug product, formulation, or use?

Revlimid may have different layers of intellectual-property protection, so “expiration” can mean different things:

- a patent covering the core drug substance or composition
- patents covering specific formulations, methods of manufacture, or dosing/regimens
- patents covering specific indications or combinations (which may extend protection even if other patents expire)

DrugPatentWatch.com groups these by patent-related entries so you can identify the specific expiration date that matches what you mean by “patent expiration.” [1]

Can generics enter right after the last Revlimid patent expires?

Even when patents expire, generic or biosimilar availability can still be affected by:

- other still-active patents in the same family or covering related claims
- regulatory exclusivity periods that are independent of patent expiration
- patent litigation that can delay approval or market entry even if one patent has expired

To see the most accurate “earliest possible entry” timeline, you generally need both the remaining active patents and any exclusivity noted for Revlimid. DrugPatentWatch.com is designed for this kind of cross-check. [1]
