Your application will initially be checked for formality requirements, and if your application is incomplete, you will be notified of the deficiencies by a letter from the USPTO, known as an Office Action. Once your application has been accepted as complete, it will be assigned into a queue for examination in about one to two years. An examiner will review the contents of the application to determine if the application meets the requirements for a patent. If the examiner does not think your application meets the requirements, the examiner will explain the reason(s). You will have opportunities to make amendments or argue against the examiner’s objections. Final rejections may be appealed to the Patent Trial and Appeal Board (PTAB). If the inventor convinces the Examiner that all requirements are met, a patent will be issued in due course.
