There are two types of patent applications.
The only version that grants the inventor full rights is called a non-provisional application. This submission begins the examination process that may lead to a patent being granted.
A provisional application only is used to establish a filing date without an examination.
A patent application is really a collection of documents that conform to US laws, rules, and guidelines.

This is the most important, which is a collection of documents that describe the invention and how it works through full, clear, concise, and exact language.
Criteria used to determine whether the description does explain how the invention works is to analyze the application through the eyes of an individual who has average knowledge and skill in the particular field of technology or subject matter that corresponds to the invention. For example, a computer patent is reviewed through the perspective of somebody who understands how computers work. A vehicle engine or auto body part will be examined from the perspective of somebody who understands how cars work.
The specification contains:
