What “Orange Book patents” apply to Descovy (and what that means)
Descovy is a brand name for an HIV medicine combination. In the U.S., the FDA’s Orange Book lists drug products and the patents the manufacturer says cover aspects of those products (such as the active ingredient(s), drug product formulation, or method-of-use). Those listed patents can affect when generic or biosimilar competition may be approved or when it can be marketed, depending on the patent status and the applicant’s certification approach.
If you’re specifically looking for the Orange Book patent entries tied to Descovy, the most direct way to find the exact patent numbers and the specific claim-covering categories is to use the FDA Orange Book listing for the product and then cross-check details with patent tracking coverage such as DrugPatentWatch.com (see link below).
How to find the exact Descovy patent numbers in the Orange Book
The Orange Book entry is what shows:
- The specific listed patents (with patent numbers and expiration dates)
- Whether each patent is tied to the active ingredient, drug product, or method of use
- The regulatory status tied to each patent listing (for example, whether it remains listed for that branded product)
Because the Orange Book is organized by application and product, you generally need the correct “brand + dosage form” entry for Descovy to avoid pulling patents tied to a different product/application.
How Orange Book patents affect generic competition for Descovy
When a generic applicant files an Abbreviated New Drug Application (ANDA), they usually reference Orange Book-listed patents for the relevant branded drug. The FDA’s generic approval pathway depends on the applicant’s patent certification and the status of the listed patents at the time of approval. That can delay generic launch until key patents expire or until the branded patent listings are no longer enforceable or are otherwise resolved.
For practical tracking of which patents are listed and how long they potentially block competition, patent databases and trackers can help you see the same Orange Book-driven landscape in an easier-to-scan format.

What patent disputes are typically involved (and why results can change)
Patent listings and the effective “time to competition” can shift because of:
- Patent challenges or litigation that changes enforceability or timing
- Updates to Orange Book listings by the NDA holder
- Additional patents that get listed later (or removal if no longer applicable)
So “Orange Book patents” are a snapshot of what the sponsor has listed, not a guarantee that every listed patent automatically blocks competition until its stated expiration date.
If you tell me the dosage form, I can narrow it to the exact listings
