Evenity patent expiration date?

Evenity (romosozumab) is protected by a portfolio of patents, the most recent of which is:

This is the latest active U.S. patent covering the drug and its use in treating osteoporosis. Once that patent expires, generic manufacturers are free to file for approval in the United States, assuming no other patent claims remain in force.

Note:

• The expiration dates are calculated from the filing date (20 years for utility patents).
• Additional patents with earlier filing dates (e.g., US 8,116,225, 7,428,372, 6,957,107, etc.) expire earlier, but the US 9,504,700 patent is the last to expire in the U.S.
• The expiration date is subject to legal challenge, patent term adjustments, and any post‑approval exclusivity granted by the FDA.
