  1. Since its creation a dozen years ago, the Federal Circuit has been a centralized court of appeals for issues of patent law. The court hears appeals from the PTO in patent prosecutions and from District Courts in patent infringement cases. Decisions of the Federal Circuit set the legal standards, unless and until the U.S. Supreme Court addresses a particular issue.
