What is patentable?

The United States Supreme Court and Chief Justice Warren E. Burger wrote that U.S. Congress had intended patentable subject matter to "include anything under the sun that is made by man," (in re Diamond v. Chakrabarty).

A 'provisional patent application' has no prescribed or required format.  You can prepare a description in any form you like.  Combine that description with this cover sheet; a small fee ($ 105); and mail it to: Commissioner of Patents, P.O. Box 1450, Alexandria, VA 22313-1450.   It is that easy.  While there is no set format, you should include as great of detail as possible including drawings.  You will have up to 12 months to convert the application to a full patent.
