As a patent examiner, your job is to review each application and determine whether or not to grant the patent for a particular invention. In this role, you review legal documents, help file paperwork, search for prior information about an invention, and write legal office actions. You do most of your examination on a computer, so much of your day involves sitting for extended periods. Patent examiners typically focus on one area or industry, such as mechanical engineering or pharmaceuticals. All patent examiner jobs are with the U.S. Patent and Trademark Office (USPTO), a part of the Federal government. Other positions that involve examining patents, such as corporate roles designed to help determine if a proposed product is violating someone else's patent, have different titles.
