Patent and Trademark Resource Center at Oklahoma State University: Provisional Patents

A provisional patent application allows you to file without a formal patent claim, oath or declaration, or any information disclosure (prior art) statement. A provisional application for patent has a pendency lasting 12 months from the date the provisional application is filed. The 12-month pendency period cannot be extended. See How to File.
