When does the Evenity (romosozumab) patent expire?
The exact expiration date depends on which specific patent is being referenced (drug composition, formulation, manufacturing process, or method-of-use). Patent terms also vary based on the filing date and whether any patent term adjustments apply.

Why you may see different “expiration” dates for Evenity
People often quote a single “patent expiration” date, but in practice the market exclusivity story for a biologic like Evenity usually depends on multiple overlapping legal protections, including:
- Different patents expiring on different dates (composition vs. method-of-use).
- Potential patent term adjustments or extensions.
- Separate exclusivity protections that can last beyond the first expiring patent (depending on jurisdiction and product status).
That’s why the most reliable answer is the “earliest” and “latest” expiration dates across the relevant patent family, rather than one universal date.
If you tell me your country, I can narrow it down
Patent expiration timing differs by country (for example, U.S. vs. EU), and the relevant patent set may differ too. If you share the country you care about (U.S., UK, EU, etc.), I can point you to the specific expiration date range for that jurisdiction using the underlying patent list.
