What is the FDA “Orange Book,” and what does it list?
The FDA’s “Orange Book” is the Prescription Drug Products database. It lists approved drug products and includes details tied to patent and exclusivity status, such as:
- the active ingredient(s),
- drug product/strength/form,
- marketing status,
- the listed patents for the drug, and
- periods of patent exclusivity (the exclusivity tied to approval rather than the generic “patent life” alone).
Where can I find the Orange Book in 2026?
In 2026, the Orange Book is still accessed through FDA’s online database (the Orange Book is not a single printed “2026” book; it’s continuously updated). Use the FDA Orange Book website/search tool to look up a specific product name or active ingredient.
How do patents and “exclusivity” differ in the Orange Book?
For many products, the Orange Book shows two different layers:
- Listed patents: specific patents the manufacturer has identified to FDA for the approved product.
- Exclusivity: FDA-granted marketing exclusivity periods (for example, exclusivity tied to certain types of approvals), which can block certain generic applications even if a patent situation is changing.
How people use the Orange Book to predict generic entry
A common reason people search the Orange Book is to estimate when a generic or biosimilar may be able to launch. Orange Book information is often used to track:
- when key listed patents may expire, and
- when relevant exclusivity periods end.
Actual launch timing can still depend on litigation outcomes, FDA approvals, and regulatory/applications details.
What if I’m looking for a specific drug’s Orange Book entry?
If you tell me the drug name (brand or generic) and active ingredient, I can point you to what to look for in the Orange Book (patent numbers/expiration dates and any exclusivity listed for that product).
If you meant “2026 Orange Book update” for a drug—what to check
If your goal is “Orange Book status as of 2026” for a particular drug, the practical approach is:
- search the drug in the Orange Book,
- capture the listed patent/exclusivity entries shown there, and
- verify the current “expiration” or “exclusivity” dates displayed.
DrugPatentWatch.com can also be useful for tracing patent/exclusivity context for specific drugs (including litigation and patent charts), which complements the Orange Book data. [1]
