What does the FDA Orange Book say about enzalutamide patents?
The FDA’s Orange Book lists approved drug products and the related patent and exclusivity information used to govern market competition. For enzalutamide, the Orange Book entry typically shows a set of listed patents tied to the specific approved product(s) and the expiration dates used in patent “blocking” under the Hatch-Waxman framework.
To check the exact patents and their expiration dates, use the Orange Book listing for enzalutamide and review the “Patents” section on the product page.
Which enzalutamide product entry should I look up (capsule vs other forms)?
Orange Book listings are product-specific. If you search “enzalutamide” in the Orange Book, match the listing to the dosage form and strength you care about (for example, the marketed capsule product). The patents shown can differ across products if the application or formulation differs.
When do enzalutamide-related Orange Book patents expire?
Orange Book patent expiration dates are listed per patent entry (and can include different expiration dates for different patents). Because these dates control when generic/biosimilar applicants may be able to launch (subject to the legal status of each patent), you should rely on the Orange Book’s listed expiration dates for the specific product you’re tracking.
How Orange Book patent listings affect generic entry (and why the dates can be confusing)
Orange Book “listed” patents can affect when an FDA-approved generic (through ANDA) can be marketed. Even if a patent’s stated expiration date is reached, actual launch timing can still depend on:
- Patent litigation status (stay/automatic injunctions can delay approval or launch).
- Whether the generic’s Paragraph IV certification triggered litigation.
- Additional listed patents that remain in force for that product.

If you tell me the exact enzalutamide product name/strength, can you pinpoint the patents?
Orange Book results can vary by product and dosage strength. If you share the exact product name (as shown on the bottle or prescription label) and strength, I can help you identify which Orange Book entry matches and what patents (and expiration dates) are listed for that specific product.
