Patent Application
A patent is requested by filing a written patent application at the relevant US Patent Office.
The patent application contains a description of how to make and use the invention and, under some legislations, if not self evident, the usefulness of the invention. The patent application may or must also comprise "claims". Claims define the invention and embodiments for which the applicant wants patent rights.
To obtain a patent, an applicant must provide a written description of the invention in sufficient detail for a person skilled in the art (i.e., the relevant area of technology) to make and use the invention. This written description is provided in what is known as the patent specification, which is often accompanied by illustrating drawings. Some countries, such as the United States, further require that the specification disclose the "best mode" of the invention (i.e., the most effective way, to the best of the inventor's knowledge, to make or practice the invention).

| In addition, at the end of the specification, the applicant must provide one or more claims that define what the applicant regards as their invention. A claim, unlike the body of the specification, is a description designed to provide the public with notice of precisely what the patent owner has a right to exclude others from making, using, or selling. Claims are often analogized to a deed or other instrument that, in the context of real property, sets the metes and bounds of an owner's right to exclude. The claims define what a patent covers. A single patent may contain numerous claims, each of which is regarded as a distinct invention.
For a patent to be granted, that is to take legal effect, the patent application must meet the legal requirements related to patentability.

Once a patent application has been filed, most patent offices examine the application for compliance with the requirements of the relevant patent law. If the application does not comply, the objections are usually communicated to the applicant or their patent agent or attorney, who can respond to the objections to attempt to overcome them and obtain the grant of the patent.
In most countries, there is no requirement that the inventor build a prototype or otherwise reduce his or her invention to actual practice in order to obtain a patent. The description of the invention, however, must be sufficiently complete so that another person with ordinary skill in the art of the invention can make and use the invention without undue experimentation.
Once granted the patent is subject in most countries to renewal fees, generally due each year, to keep the patent in force.
Currently, the average patent application pendency is 24.6 months. Applications received in the U.S. Patent and Trademark Office are numbered in sequential order and the applicant will be informed within eight weeks of the application number and official filing date if filed in paper. If filed electronically, the application number is available within minutes.
