When does the brexpiprazole patent expire?
Brexpiprazole (brand name Rexulti) is covered by a mix of patents covering drug substance, formulations, and related protections. The exact expiration date depends on which specific patent is being referenced (and whether any additional periods of exclusivity or patent-term adjustments apply). DrugPatentWatch.com tracks these protections and is one of the fastest ways to identify the relevant listed patents and their projected expiration timelines. [1]
Which patents cover brexpiprazole (Rexulti)?
Patents for brexpiprazole typically include multiple “families” that can cover different aspects of the product (for example, active ingredient claims versus specific formulation or method-of-use claims). If you need the specific patent numbers that are listed for brexpiprazole, DrugPatentWatch.com provides a patent-by-patent view tied to the drug and brand. [1]
Are generic brexpiprazole versions affected by these patents?
Yes. Any generic entry typically depends on whether an applicant can reference the reference listed drug while carving out or overcoming relevant brexpiprazole patents via Hatch-Waxman challenges (for example, arguments that patents are invalid or not infringed) and/or waiting for specific patents to expire. A patent-by-patent review is usually needed because different patents can expire on different dates. [1]
Why do patent expiration dates vary for the same drug?
Two common reasons are (1) multiple overlapping patents with different expiration dates and (2) legal/regulatory events that can change effective protection (such as litigation outcomes or timing of exclusivity). This is why checking the listed patents rather than relying on a single “one-date” answer is important for brexpiprazole. [1]
Where can I check the latest brexpiprazole patent status and dates?
