A patent is a set of exclusive rights granted by a state to a person for a fixed period of time in exchange for the regulated, public disclosure of certain details of a device, method, process or composition of matter (substance) (known as an invention) which is new, inventive, and useful or industrially applicable.
The exclusive right granted to a patentee in most countries is the right to prevent others from making, using, selling, offering to sell or importing the claimed invention. The rights given to the patentee do not include the right to make, use, or sell the invention themselves. The patentee may have to comply with other laws and regulations to make use of the claimed invention. So, for example, a pharmaceutical company may obtain a patent on a new drug but will be unable to market the drug without regulatory approval, or an inventor may patent an improvement to a particular type of laser, but be unable to make or sell the new design without a license from the owner of an earlier broader patent covering lasers of that type.
The term "patent" originates from the Latin word patere which means "to lay open" (i.e. make available for public inspection) and the term letters patent, which originally denoted royal decrees granting exclusive rights to certain individuals or businesses.
Legal effect
A modern patent provides the right to exclude others from making, using, selling, offering for sale, or importing the patented invention for the term of the patent, usually 20 years. A patent is, in effect, a limited property right that the government offers to inventors in exchange for their agreement to share the details of their inventions with the public. Like any other property right, it may be sold, licensed, mortgaged, assigned or transferred, or simply given away.
In order to obtain a patent, an applicant must provide a written description of his or her invention in sufficient detail for a person skilled in the art to make and use the invention. This written description is provided in what is known as the patent specification, which often is accompanied by figures that show how the invention is made and how it operates. In addition, at the end of the specification, the applicant must provide the patent office with one or more claims that distinctly point out what the applicant regards as his or her 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 or does not cover. A single patent may contain numerous claims, each of which is regarded as a distinct invention.
In order for a patent to be granted, that is to take legal effect, the patent application must meet the requirements of the national law related to patentability. In the United States, only the inventor or his/her legal representative may apply for a patent.
A patent is an exclusionary right-it gives the right to exclude others from infringing the patent, but that does not necessarily give the owner of the patent the right to exploit the patent. For example, many inventions are improvements of prior inventions which may still be covered by someone else's patent. If an inventor takes an existing patented mouse trap design, adds a new feature to make an improved mouse trap, and obtains a patent on the improvement, he or she can only legally build his or her improved mouse trap with permission from the patent holder of the original mouse trap, assuming the original patent is still in force. On the other hand, the owner of the improved mouse trap can exclude the original patent owner from using the improvement.
Patents are solely enforced through civil lawsuits (for example, for a US patent, by an action for patent infringement in a United States federal court). 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.
An important limitation on the ability of a patent owner to successfully assert his or her patent in civil litigation is the accused infringer's right to challenge the validity of that patent. Civil courts hearing patent cases can and often do declare patents invalid. The grounds on which a patent can be found invalid are set out in the relevant patent legislation and vary between countries. Often, the grounds are a sub-set of the requirements for patentability in the relevant country.
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. It is not uncommon 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 highly desirable to the mouse trap developers discussed above, for example, because it would permit both parties to profit off each other's inventions.

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 harmonisation of patent laws, with the 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 highly notable international convention related to patents is the Paris Convention for the Protection of Industrial Property which was initially agreed 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, 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.
The authority for patent statutes in different countries varies. In the United States for instance, the Patent and Trademark Office gets its authority from statutes in [Title 35] of the United States Code, which in turn is based on Article One, Section 8(8) of the U.S. Constitution. In the UK, substantive patent law is contained in the Patents Act 1977 as amended.United Kingdom law requiring no explicit authority due to the Supremacy of Parliament.The United Kingdom Patent Office is run under power granted by the Patents Act 1905.
([Disputed statementdisputed]—see [European Patent Convention (EPC) (administered by the European Patent Office (EPO), and covering approximately 30 European states, including all European Union states except Malta) and the Patent Cooperation Treaty (PCT) (administered by WIPO and covering approximately 120 countries worldwide), that centralise some portion of the filing and examination procedure.
The EPO examines and grants patents which are or can be then given force by the national laws of the EPC contracting states. Singer/Stauder, The European Patent Convention, A Commentary, Munich, 2003, under Article 2 The EPC leaves infringment of European Patents, once granted, to national law. The grant of a patent under the EPC can be thought of as a bundle of national patents having independent validity and scope rather than a single pan-European patent. ([Disputed statementdisputed]—see [[a European patent] comes into existence (...) as a bundled European patent having both European and national protective effect". "The view that, after grant, a European patent breaks up into a bundle of national patents in designated Contracting States may appear plausible, but it is incorrect both in law and systematically". (Singer/Stauder, The European Patent Convention, A Commentary, Munich, 2003, under Article 2.)
The PCT does not provide a central, international, granting authority, but rather allows a number of the common procedural steps required to obtain a patent to be carried out for a single application. The PCT system is therefore an efficient route to obtaining a patent in a large number of countries as many of the steps need only be performed once. A PCT application also delays many of the highly-expensive stages of prosecuting a patent.
First, in accordance with the original definition of the term "patent," it is argued that patents facilitate and encourage disclosure of innovations into the public domain for the common good. If inventors did not have the legal protection of patents, they may prefer or tend to keep their inventions secret. Awarding patents generally makes the details of new technology publicly available, for exploitation by anyone after patent protection ends, or for further improvement by other inventors. Furthermore, when a patent's term has expired, the public record ensures that the patentee's idea is not lost to humanity.
Second, it is broadly believed that patents provide incentives for economically efficient research and development (R&D). Many large modern corporations have annual R&D budgets of hundreds of millions or even billions of dollars. Without patent protection, R&D spending would be significantly less or eliminated altogether, limiting the possibility of technological advances or breakthroughs. Corporations would be much more conservative about the R&D investments they made, as third parties would be free to exploit any developments. This second justification is closely related to the basic idea underlying traditional property rights: why build a house if another person could freely occupy it?
Third, in many industries (especially those with high fixed costs and low marginal costs and low reverse engineering costs - pharmaceuticals and computer software being two prototypical examples), once an invention exists and has been tested, the cost of turning it into a product is typically six times or more the R&D cost. #redirect Unless there is some way to prevent copies from competing at the marginal cost of production, companies will not make that productization investment.
Fourth, many believe that patent rights create an incentive for companies to develop workarounds to patented inventions, thereby creating improved or alternative technologies that might not otherwise have been developed.
One interesting side effect of modern day patent usage is that the small-time inventor can use the exclusive right status to become a licensor. This allows the inventor to accumulate capital quickly from licensing the invention and may allow rapid innovation to occur because he/she may choose to not manage a manufacturing buildup for the invention. Thus the inventor's time and energy can be spent on pure innovation, allowing others to concentrate on manufacturability.
There are arguments in opposition to patent rights. Granting a patent confers a "negative right" upon a patent owner, because he or she may legally exclude competitors from using or exploiting the invention, even if the competitor subsequently (either subsequent to the date of invention, or to the priority date, depending upon the relevant patent law - see First to file and first to invent) independently develops the same invention. Also, it is argued that monopolies create inefficiency. If the grant of a patent is the grant of a monopoly, the patent system may stifle competition and result in higher prices, lower quality, and shortages.
A more subtle, but theoretical, problem with patent rights was developed by law professors Michael Heller and Rebecca Eisenberg in a 1998 Science article.Heller, M.A., & Eisenberg, R.S. (1998). Can Patents Deter Innovation? The Anticommons in Biomedical Research. Science, 280(1 May 1998), 280, 698-701. Building from Heller's theory of the tragedy of the anticommons, the professors postulated that intellectual property rights may become so widely fragmented that, effectively, no one can take advantage of them as to do so would require an agreement between the owners of all of the fragments.
All patents are published and so there is a tension between including sufficient detail in the patent application to secure patent protection and the wish to protect "trade secrets." It has been argued that the sufficiency requirements of patents are not rigorous enough and that patents are sometimes granted without any knowledge being imparted to society, this tends to be particular to software patents, wherein the source code is not revealed. [www.bustpatents.com], retrieved on June 29, 2006 It has also been suggested that market incentives alone would be sufficient incentive to innovate even in the absence of patents.
In the last 10 years, patent offices in both the U.S. and Europe have begun granting software patents. Programmers and others complain that these patents inhibit software innovation in a rapidly changing field where a particular technique may be obsolete in a few short years.[lpf.ai.mit.edu], retrieved on June 29, 2006
Historical evidence can be found both in favour of patent systems and against them. The mid-19th century dyestuffs industry faltered in Britain where patent protection was available, and flourished in Germany despite the absence of such protections. In contrast, patent protection has enabled inventors to protect their innovative products from larger companies and receive reward for their advances. For example, the Dyson bagless vacuum cleaner has led to a significant shift in the vacuum cleaner market and the inventor has benefitted from patent protection.
In response to perceived problems with the grant of patents, and the evolving nature of technology and industry, there is on-going debate about, and reform of, patent systems around the world. The TRIPs agreement, developed by the WTO has led to the alignment of many patent systems with regard to certain controversial issues, such as what can be protected by patents and the issue of compulsory licences in cases of national need. There is also an active community who oppose patents and who lobby for the abolishment of patent systems.
Although there is evidence suggesting that something like patents was used among some ancient Greek cities, patents in the modern sense originated in Italy in 1474. At that time the Republic of Venice issued a decree by which new and inventive devices, once they had been put into practice, had to be communicated to the Republic in order to obtain legal protection against potential infringers. England followed with the Statute of Monopolies in 1623 under King James I, which declared that patents could only be granted for "projects of new invention." During the reign of [Queen Anne] (1702-1714), the lawyers of the English Court developed the requirement that a written description of the invention must be submitted. [http://www.patent.gov.uk/copy/history/index.htm], retrieved on June 29, 2006 These developments, which were in place during the Colonial period, formed the basis for modern English and United States patent law.
In the United States, during the colonial period and Articles of Confederation years (1778-1789), several states adopted patent systems of their own. The first Congress adopted a Patent Act, in 1790.
Once a patent application has been filed, a patent office examines that application for compliance with the requirements of the relevant patent law. If the application does not comply with all of the requirements, the objections are communicated to the Applicant (or his representative), who can then respond to those objections to attempt to overcome them to obtain the grant of a patent.
Once granted the patent is subject in most countries to renewal fees, generally due each year, to keep the patent in force.

Obtaining a patent
A patent is obtained by filing a written application at the relevant patent office. That application will contain a specification detailing the invention and the protection claimed, together with forms relating to the procedural aspects of obtaining a patent. In most countries, including the United States, there is no requirement that the inventor actually build a prototype or otherwise reduce his or her invention to practice in order to obtain a patent.References
