Definition

The term patent usually refers to a right granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof. The additional qualification utility patents is used in countries such as the United States to distinguish them from other types of patents but should not be confused with utility models granted by other countries.

Law

The rights conveyed by a patent vary country-by-country. For example, in the United States, a patent covers research, except "purely philosophical" inquiry. A U.S. patent is infringed by any "making" of the invention, even a making that goes toward development of a new invention — which may itself become subject of a patent. In contrast, Australian law permits others to build on top of a patented invention, by carving out exceptions from infringement for those who conduct research (e.g. for academic purposes) on the invention.

Some countries have "working provisions" which require that the invention be exploited in the jurisdiction it covers. Consequences of not working an invention vary from one country to another, ranging from revocation of the patent rights to the awarding of a compulsory license awarded by the courts to a party wishing to exploit a patented invention. The patentee has the opportunity to challenge the revocation or license, but is usually required to provide evidence that the reasonable requirements of the public have been met by the working of invention.

Enforcement

Patents can generally only be enforced through civil lawsuits (for example, for a U.S. patent, by an action for patent infringement in a United States federal court), although some territories (such as France and Austria) have criminal penalties for wanton infringement. Typically, the patent owner will seek monetary compensation for past infringement, and will seek an injunction prohibiting the defendant from engaging in future acts of infringement. In order to prove infringement, the patent owner must establish that the accused infringer practices all of the requirements of at least one of the claims of the patent (noting that in many jurisdictions the scope of the patent may not be limited to what is literally stated in the claims, for example due to the "doctrine of equivalents").

The vast majority of patent rights, however, are not determined through litigation, but are resolved privately through patent licensing. Patent licensing agreements are effectively contracts in which the patent owner (the licensor) agrees not to sue the licensee for infringement of the licensor's patent rights, usually in return for a royalty or other payment. It is common for companies engaged in complex technical fields to enter into dozens of license agreements associated with the production of a single product. Moreover, it is equally common for competitors in such fields to license patents to each other under cross-licensing agreements in order to gain access to each other's patents. A cross license agreement could be desirable to the mouse trap developers discussed above, for example, because it would permit both parties to profit off each other's inventions.

The United Nations Statistics Division reports that the United States was the top market for patents in force in 2000 closely followed by the EU and Japan.

Ownership

In most countries, both natural persons and corporate entities may apply for a patent. The entity or entities then become the owners of the patent when and if it issues. However, it is nearly always required that the inventor or inventors be named and an indication be given on the public record as to how the owner or owners acquired their rights to the invention from the inventor or inventors.

The ability to assign ownership rights increases the liquidity of a patent as property. Inventors can obtain patents and then sell them to third parties. The third parties then own the patents as if they had originally made the inventions themselves

Governing laws

The grant and enforcement of patents are governed by national laws, and also by international treaties, where those treaties have been given effect in national laws. Patents are, therefore, territorial in nature.

Commonly, a nation forms a patent office with responsibility for operating that nation's patent system, within the relevant patent laws. The patent office generally has responsibility for the grant of patents, with infringement being the remit of national courts.

There is a trend towards global harmonization of patent laws, with the World Trade Organization (WTO) being particularly active in this area. The TRIPs Agreement has been largely successful in providing a forum for nations to agree on an aligned set of patent laws. Conformity with the TRIPs agreement is a requirement of admission to the WTO and so compliance is seen by many nations as important. This has also led to many developing nations, which may historically have developed different laws to aid their development, enforcing patents laws in line with global practice.

A key international convention relating to patents is the Paris Convention for the Protection of Industrial Property, initially signed in 1883. The Paris Convention sets out a range of basic rules relating to patents, and although the convention does not have direct legal effect in all national jurisdictions, the principles of the convention are incorporated into all notable current patent systems. The most significant aspect of the convention is the provision of the right to claim priority: filing an application in any one member state of the Paris Convention preserves the right for one year to file in any other member state, and receive the benefit of the original filing date. Because the right to a patent is intensely date-driven, this right is fundamental to modern patent usage.

Application and prosecution

A patent is requested by filing a written application at the relevant patent office. The 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. 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 age
