For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.
The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
