# Appeal

A request to have a patent examiner's rejection reviewed by a higher authority. After receiving multiple rejections, an applicant can appeal to the Patent Trial and Appeal Board (PTAB) within the USPTO, and from there to federal court. Appeals are expensive and slow, but sometimes necessary when an examiner applies the law incorrectly.
