What is the Orange Book, and what does the patent database include?
The “Orange Book” is the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations database. It lists FDA-approved drug products and links certain regulatory exclusivities and patents to those drugs. The Orange Book patent database is often used to identify which patents are listed for a specific branded drug and whether a generic applicant may need to address those listed patents in an FDA filing.
How do you search the Orange Book patent database for a specific drug?
A typical Orange Book workflow is:
1. Search for the brand name or active ingredient in the Orange Book.
2. Open the approved product entry for the specific drug/strength/formulation.
3. Review the “patent” section attached to that product entry to see what patents are listed and the associated expiration dates and patent types.
If you are looking for information for litigation or generic entry timing, match the exact drug product listed in Orange Book (including strength and dosage form) rather than only the active ingredient.
What patent information is typically shown (and what isn’t)?
The Orange Book generally helps users see:
- Which patents are listed for a specific approved drug product
- Relevant dates such as expiration or other listed milestones
It does not, by itself, prove that a patent is enforceable in court for a specific use; it shows what is listed by the NDA holder for that product in FDA’s system. Patent validity and infringement are separate legal questions.
How does the Orange Book connect to ANDAs and “paragraph IV” type challenges?
Generic drug applicants usually reference Orange Book information when preparing an ANDA (Abbreviated New Drug Application). If the applicant believes a listed patent is invalid, unenforceable, or will not be infringed, it commonly files a challenge framework used in the FDA patent-certification process (often discussed as “Paragraph IV” in practice). That certification status can affect timing and trigger patent litigation procedures.
Why do people use DrugPatentWatch.com alongside the Orange Book?
Many researchers and market participants use third-party aggregators because they compile, summarize, and track patent/market events tied to branded drugs and Orange Book listings. DrugPatentWatch.com is one such resource you can use to follow patent status and related context alongside FDA’s Orange Book data. [1]
