Patent

A patent ( or ) is a set of exclusive rights granted by a state (national government) to an inventor or their assignee for a limited period of time in exchange for a public disclosure of an invention.

The procedure for granting patents, the requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims defining the invention which must be new, non-obvious, and useful or industrially applicable. In many countries, certain subject areas are excluded from patents, such as business methods, treatment of the human body, and mental acts. The exclusive right granted to a patentee in most countries is the right to prevent others from making, using, selling, or distributing the patented invention without permission. It is just a right to prevent others' use. A patent does not give the proprietor of the patent the right to use the patented invention, should it fall within the scope of an earlier patent.

Under the World Trade Organization's (WTO) Agreement on Trade-Related Aspects of Intellectual Property Rights, patents should be available in WTO member states for any inventions, in all fields of technology, and the term of protection available should be the minimum twenty years.

The Florentine architect Filippo Brunelleschi received a three-year patent for a barge with hoisting gear, that carried marble along the Arno River in 1421. In 1449, King Henry VI granted the first patent with a license of 20 years to John of Utynam for introducing the making of colored glass to England.

Patents in the modern sense originated in 1474, when the Republic of Venice enacted a decree that new and inventive devices, once put into practice, had to be communicated to the Republic to obtain the right to prevent others from using them.

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 (1702–14), the lawyers of the English Court developed the requirement that a written description of the invention must be submitted. The patent system in many other countries, including Australia, is based on British law and can be traced back to the Statute of Monopolies.

In France, patents were granted by the monarchy and by other institutions like the "Maison du Roi". The Academy examined novelty. Examinations were generally done in secret with no requirement to publish a description of the invention. Actual use of the invention was deemed adequate disclosure to the public. The modern French patent system was created during the Revolution in 1791. Patents were granted without examination since inventor's right was considered as a natural one

In the United States, during the so-called colonial period and Articles of Confederation years (1778–89), several states adopted patent systems of their own. The first Congress adopted a Patent Act, in 1790, and the first patent was issued under this Act on July 31, 1790 (to Samuel Hopkins of Vermont for a potash production technique).

Law

Effects

A patent is not a right to practice or use the invention. Rather, a patent provides the right to exclude others subject to the payment of maintenance fees. 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, given away, or simply abandoned.

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.

A patent being an exclusionary right does not, however, necessarily give the owner of the patent the right to exploit the patent. For example, many inventions are improvements of prior inventions that may still be covered by someone else's patent. 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. To prove infringement, the patent owner must establish that the accused infringer practices all the requirements of at least one of the claims of the patent. (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").

An important limitation on the ability of a patent owner to successfully assert the 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 not valid. A patent can be found invalid on grounds that are set out in the relevant patent legislation that vary between countries. Often, the grounds are a subset of requirements for patentability in the relevant country. Although an infringer is generally free to rely on any available ground of invalidity (such as a prior publication, for example), some countries have sanctions to prevent the same validity questions being relitigated. An example is the UK Certificate of contested validity.

Patent licensing agreements are contracts in which the patent owner (the licensor) agrees to forgo their right to sue the licensee for infringement of the licensor's patent rights, usually in return for a royalty or other compensation. 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 share the benefits of using each other's patented inventions.

Therefore, patents may be enforced through litigation, and a common defense is an invalidity challenge. Patents may also be subject to licensing agreements. The vast majority of patents are however never litigated or even licensed.

Ownership

In most countries, both natural persons and corporate entities may apply for a patent. In the United States, however, only the inventor(s) may apply for a patent although it may be assigned to a corporate entity subsequently and inventors may be required to assign inventions to their employers under a contract of employment. In most European countries, ownership of an invention may pass from the inventor to their employer by rule of law if the invention was made in the course of the inventor's normal or specifically assigned employment duties, where an invention might reasonably be expected to result from carrying out those duties, or if the inventor had a special obligation to further the interests of the employer's company.

The inventors, their successors or their assignees become the proprietors of the patent when and if it is granted. If a patent is granted to more than one proprietor, the laws of the country in question and any agreement between the proprietors may affect the extent to which each proprietor can exploit the patent. For example, in some countries, each proprietor may freely license or assign their rights in the patent to another person while the law in other countries prohibits such actions without the permission of the other proprietor(s).

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 and have the same rights to prevent others from exploiting the claimed inventions, 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.

The authority for patent statutes in different countries varies. In the UK, substantive patent law is contained in the Patents Act 1977 as amended. In the United States, the Constitution empowers Congress to make laws to "promote the Progress of Science and useful Arts..." The laws Congress passed are codified in Title 35 of the United States Code and created the United States Patent and Trademark Office.

In addition, there are international treaty procedures, such as the procedures under the European Patent Convention (EPC) [administered by the European Patent Organisation (EPOrg)], and the Patent Cooperation Treaty (PCT) (administered by WIPO and covering more than 140 countries), that centralize some portion of the filing and examination procedure. Similar arrangements exist among the member states of ARIPO and OAPI, the analogous treaties among African countries, and the nine CIS member states that have formed the Eurasian Patent Organization.

Application and prosecution

A patent is requested by filing a written application at the relevant patent office. The person or company filing the application is referred to as "the applicant". The applicant may be the inventor or its assignee. The application contains a description of how to make and use the invention that must provide sufficient detail for a person skilled in the art (i.e., the relevant area of technology) to make and use the invention. In some countries there are requirements for providing specific information such as the usefulness of the invention, the best mode of performing the invention known to the inventor, or the technical problem or problems solved by the invention. Drawings illustrating the invention may also be provided.

The application also includes one or more claims, although it is not always a requirement to submit these when first filing the application. The claims set out what the applicant is seeking to protect in that they define what the patent owner has a right to exclude others from making, using, or selling, as the case may be. In other words, the claims define what a patent covers or the "scope of protection".

After filing, an application is often referred to as "patent pending". While this term does not confer legal protection, and a patent cannot be enforced until granted, it serves to provide warning to potential infringers that if the patent is issued, they may be liable for damages.

For a patent to be granted, that is to take legal effect in a particular country, the patent application must meet the patentability requirements of that country. Most patent offices examine the application for compliance with these requirements. If the application does not comply, objections are communicated to the applicant or their patent agent or attorney and one or more opportunities to respond to the objections to bring the application into compliance are usually provided.

Once granted the patent is subject in most countries to renewal fees to keep the patent in force. These fees are generally payable on a yearly basis, although the US is a notable exception. Some countries or regional patent offices (e.g. the European Patent Office) also require annual renewal fees to be paid for a patent application before it is granted.

Economics

Rationale

There are four primary incentives embodied in the patent system: to invent in the first place; to disclose the invention once made; to invest the sums necessary to experiment, produce and market the invention; and to design around and improve upon earlier patents. in their R&D; departments. If the investments can be considered as inputs of R&D;, patents are the outputs. Based on these groups, a project named Corporate Invention Board, had measured and analyzed the patent portfolios to produce an original picture of their technological profiles. Without patents, 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 ideas underlying traditional property rights. #In accordance with the original definition of the term "patent," 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, in many cases, they would prefer or tend to keep their inventions secret . Awarding patents generally makes the details of new technology publicly available, for exploitation by anyone after the patent expires, 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.

Another effect of modern patent usage is to cause competitors to design around (or to "invent around" according to R S Praveen Raj) each other's patents. This may promote healthy competition among manufacturers, resulting in gradual improvements of the technology base. This may help augment national economies and confer better living standards to the citizens.

Costs

Some of the costs to society associated with the granting of a patent are: the immediate costs associated with preparing the patent; patent office work; legal costs associated with prosecuting alleged infringements; business costs associated with those legal actions; increasing the cost of determining whether a method is covered by an existing patent, and reduced certainty in the result; restrictions on the use of the patented method (particularly in cases where the method is redeveloped independently).

The costs of preparing and filing a patent application, prosecuting it until grant and maintaining the patent vary from one jurisdiction to another, and may also be dependent upon the type and complexity of the invention, and on the type of patent.

The European Patent Office estimated in 2005 that the average cost of obtaining a European patent (via a Euro-direct application, i.e. not based on a PCT application) and maintaining the patent for a 10 year term was around 32 000 Euro. Since the London Agreement entered into force on May 1, 2008, this estimation is however no longer up-to-date, since fewer translations are required.

In the United States, direct legal costs of patent litigation are on average in the order of a million dollars per case, not including associated business costs, based on an American Intellectual Property Law Association (AIPLA) survey of patent lawyers (2005), and court documents for a sample of 89 court cases where one side was ordered to pay the other side's legal fees.

Criticism

Patents have been criticized both in principle and in implementation.

In principle, patents have been criticized as a restraint of trade, for conferring a negative right upon a patent owner, permitting them to exclude competitors from using or exploiting the invention, even if the competitor subsequently develops the same invention independently. This may be 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).

As state-granted monopolies, patents have been criticized as inconsistent with free trade. On that basis, in 1869 the Netherlands abolished patents, and did not reintroduce them until 1912.

In implementation, patents have been criticized for being granted on already-known inventions. In 1938, R. Buckminster Fuller wrote of the patent application process in the United States:

At present, the files, are so extraordinarily complex and the items so multitudinous that a veritable army of governmental servants is required to attend them and sort them into some order of distinguishable categories to which reference may be made when corresponding with patent applicants for the purposes of examiner citation of "prior art" disclosure. This complexity makes it inevitable that the human-equation involved in government servants relative to carelessness or mechanical limitations should occasion the granting of multitudes of "probably" invalid patent claims.

Patents may hinder innovation as well in the case of "troll" entities. A holding company, pejoratively known as a "patent troll", owns a portfolio of patents, and sues others for infringement of these patents while doing little to develop the technology itself. Other commentators suggest that patent trolls are not bad for the patent system at all but instead realign market participant incentives, make patents more liquid, and clear the patent market.

Another theoretical problem with patent rights was proposed by law professors Michael Heller and Rebecca Sue Eisenberg. Based on Heller's theory of the tragedy of the anticommons, the authors argued that intellectual property rights may become so 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.

Pharmaceutical patents prevent generic alternatives to enter the market until the patents expire, and thus maintains high prices for medication. This can have significant effects in the developing world, as those who are most in need of basic essential medicines are unable to afford such high priced pharmaceuticals. Critics also question the rationale that exclusive patent rights and the resulting high prices are required for pharmaceutical companies to recoup the large investments needed for research and development. Other articles shed light on the problems of today's medical research. It sets wrong priorities in research and pricing, and pushes the state-run healthcare systems even of rich nations to their limits.

In one response to these criticisms, one review concluded that less than 5 percent of medicines on the World Health Organization's list of essential drugs are under patent. Also, the pharmaceutical industry has contributed US$2 billion for healthcare in developing countries, providing HIV/AIDS drugs at lower cost or even free of charge in certain countries, and has used differential pricing and parallel imports to provide medication to the poor. Such imbalance is also recognized between freedom rights and exclusion rights by the computing profession.

Concerns of a similar order have also been documented elsewhere, showing that public campaigns have had a concern for "preventing the over-reach" of IP protection including patent protection, and "to retain a public balance in property rights" of this kind. The same source also noted the shift that had taken place away from the historical classification of such rights as "grants of privilege", towards referring to them in terms of property and rights; a change that encouraged a change of view of the relation of sovereign governments towards them, away from something that the government "may grant" towards a "duty to uphold them". While many individuals in the developed world are covered by health insurance and therefore never see the true cost of their drugs, significant numbers of people outside it are not able to afford them.

Several alternatives have been proposed to address the issue of financial incentivization. Joseph Stiglitz, professor of economics at Columbia University, offers in his book "Prizes, not patents" the idea of providing significant monetary compensation as a substitute for the lost profits associated with abstaining from the monopoly given by a patent. Under this system, the pharmaceutical industry would theoretically still achieve the financial benefits they seek in return for investing in the development process but, without a market monopoly, generic versions of the drug would be immediately available with a significant reduction in cost.

A different proposition to satisfy both the needs of the pharmaceutical industry, and the would-be patient, is to remove the issue of financing development from the private sphere all together, and to cover the costs with direct government funding. This alternative is favored by economist Dean Baker, of the Center for Economic and Policy Research, as a more practical method of retaining research incentives. He outlines the simplicity of this option in writing "This (government funding) already occurs on a massive scale. In fact, the $30 billion that the United States federal government pays each year to support bio-medical research at its National Institutes of Health (NIH) is approximately 20 percent larger than the $25 billion that its pharmaceutical industry claims to spend on research".
