Before June 2004, the USPTO registration exam was a pencil-and-paper test given at approximately 15 locations around the country. The USPTO has moved to a computer-based examination which can be taken on any business day at any of several hundred Prometric locations around the country. A sample computerized exam is available to provide a feel for how the exam is administered, but this "practice exam" contains no sample questions. Once an applicant has been approved to sit for the exam, he or she has 90 days in which to schedule an examination date with Prometric.
