Patent law was enacted by Congress under the power given by Article I of the Constitution “to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” A patent gives an inventor the exclusive right to make, use, and sell an invention for 20 years. It protects a process, product, invention, machine, or the improvement of any of these. Note that a patent gives the inventor the right to exclude others from making, selling, or using the invention.
A patent is defined as a process, art (as in "state of the art") or method, and includes a new use of known process, machine, manufacture, composition of matter, or material. A machine is a particular apparatus for achieving a certain result or carrying out a distinct process (i.e., printing press).
A “manufacture” is an article or a product such as a television. A composition of matter is a new arrangement of elements so that the resulting compound, such as a metal alloy, is not found in nature. In addition, genetically engineered living organisms may be patented. Improvements are an alteration of a process, machine, manufacture, or composition of matter may also be patented. Finally, new and original ornamental designs for articles of manufacture are patentable (i.e., the shape of a bottle), but works of art are not patentable and therefore must seek protection from copyright law.
Laws of nature (e.g., gravity), natural phenomena (e.g., copper), and abstract ideas cannot be patented. The rationale here is that these items are not invented; they merely exist. However, a process created to understand or extract these items could be patentable.
For many years, software programs were deemed not patentable because the code incorporated automation of manual process or mathematical equations, both of which could not be patented. However, in 1998, the Supreme Court held that patents could be obtained for a process that incorporated a computer program if the process itself was patentable.
Business processes can also be patented. For example, Amazon obtained a patent for its "one-click" ordering system, a method of processing credit-card orders securely. However, this patent could not keep Amazon from shutting down Barnesandnoble.com's Express one-click ordering system.
In order for a patent to be issued, several requirements must be met. We'll focus on the following three:
The first step is to determine which type of patent application is appropriate. The following categories are recognized under patent law:
Remember that utility patents protect the way an invention is used and works whereas a design patent protects the way an article looks. Note that a design patent only grants protection for 15 years.

An interesting phenomenon of late has been the rise (and likely recent fall) of so-called patent trolls. Simply put, an individual or business may purchase an obscure patent for a minimal amount and then use that patent to demand money from profitable companies that may (or may not) be infringing on the troll's newly-acquired patent. To see how this process has been abused, read this article about a recent patent troll.
