Patent
12/04/2020A patent is a form of intellectual property that gives the owner the legal right to exclude others from making, using, selling and importing an invention for a limited period of years, in exchange for publishing an enabling public disclosure of the invention. In most countries patent rights fall under civil law and the patent holder needs to sue someone infringing the patent in order to enforce his or her rights. In some industries patents are an essential form of competitive advantage; in others they are irrelevant.
The procedure for granting patents, 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 that define the invention. A patent may include many claims, each of which defines a specific property right. These claims must meet relevant patentability requirements, such as novelty, usefulness, and non-obviousness.
Under the World Trade Organization’s (WTO) TRIPS Agreement, patents should be available in WTO member states for any invention, in all fields of technology, provided they are new, involve an inventive step, and are capable of industrial application. Nevertheless, there are variations on what is patentable subject matter from country to country, also among WTO member states. TRIPS also provides that the term of protection available should be a minimum of twenty years.
The word patent originates from the Latin patere, which means “to lay open” (i.e., to make available for public inspection). It is a shortened version of the term letters patent, which was an open document or instrument issued by a monarch or government granting exclusive rights to a person, predating the modern patent system. Similar grants included land patents, which were land grants by early state governments in the USA, and printing patents, a precursor of modern copyright.
In modern usage, the term patent usually refers to the right granted to anyone who invents something new, useful and non-obvious. Some other types of intellectual property rights are also called patents in some jurisdictions: industrial design rights are called design patents in the US, plant breeders’ rights are sometimes called plant patents, and utility models and Gebrauchsmuster are sometimes called petty patents or innovation patents.
The additional qualification utility patent is sometimes used (primarily in the US) to distinguish the primary meaning from these other types of patents. Particular species of patents for inventions include biological patents, business method patents, chemical patents and software patents.
Patentable
To qualify for a patent, the invention must meet three basic tests. First, it must be novel, meaning that the invention did not previously exist. Second, the invention must be non-obvious, which means that the invention must be a significant improvement to existing technology. Simple changes to previously known devices do not comprise a patentable invention. Finally, the proposed invention must be useful. Legal experts commonly interpret this to mean that no patent will be granted for inventions that can only be used for an illegal or immoral purpose.
Some types of discoveries are not patentable. No one can obtain a patent on a law of nature or a scientific principle even if he or she is the first one to discover it. For example, Isaac Newton could not have obtained a patent on the laws of gravity, and Albert Einstein could not have patented his formula for relativity, E=mc2.
Under the law of the European Patent Convention (EPC), patents are only granted for inventions which are capable of industrial application, which are new and which involve an inventive step. An invention may be defined as a proposal for the practical implementation of an idea for solving a technical problem. An invention is capable of industrial application if it can be made or used in any kind of industry, including agriculture, as distinct from purely intellectual or aesthetic activity.
An invention is said to be new if, prior to the date of filing or to the priority date accorded to the application from an earlier application for the same invention, it was not already known to the public in any form (written, oral or through use), ie it did not form part of the state of the art. An invention is said to involve an inventive step if, in the light of what is already known to the public, it is not obvious to a so-called skilled person, i.e someone with good knowledge and experience of the field.
Under the Indian patent law a patent can be obtained only for an invention which is new and useful. The invention must relate to a machine, article or substance produced by manufacture, or the process of manufacture of an article. A patent may also be obtained for an improvement of an article or of a process of manufacture. In regard to medicine or drug and certain classes of chemicals no patent is granted for the substance itself even if new, but a process of manufacturing and substance is patentable. The application for a patent must be true and the first inventor or the person who has derived title from him, the right to apply for a patent being assignable.
Non Patentable
Some inventions cannot be patented. Under the law of the European Patent Convention (EPC) the list of non-patentable subject-matter includes methods of medical treatment or diagnosis, and new plant or animal varieties. Further information on such fields can be obtained from a patent attorney. Nor may patents be granted for inventions whose exploitation would be contrary to public order or morality (obvious examples being land-mines or letter-bombs).The following are not regarded as inventions: discoveries; scientific theories and mathematical methods; aesthetic creations, such as works of art or literature; schemes, rules and methods for performing mental acts, playing games or doing business; presentations of information; computer software.
Under the Indian law the following are non patentable (as mentioned under section 3 and 5 of Indian Patents Act, 1970):
An invention which is frivolous or which claims anything obvious contrary to well established natural laws. An invention the primary or intended use of which would be contrary to law or morality or injurious to public heath. The mere discovery of a scientific principle or the formulation of an abstract theory.
The mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.
A substance obtained by a mere admixture resulting only in the aggregation of the properties of the components thereof or a process for producing such substance The mere arrangement or re-arrangement or duplication of known devices each functioning independently of one another in a known way. A method or a process of testing applicable during the process of manufacture for rendering the machine, apparatus or other equipment more efficient or for the improvement or restoration of the existing machine, apparatus or other equipment or for the improvement or control of manufacture.
A method of agriculture or horticulture. Any process for the medicinal, surgical, curative, prophylactic or other treatment of human being or any process for a similar treatment of animals or plants to render them free of disease or to increase their economic value or that of their products.
No Patent shall be granted in respect of an invention relating to Atomic energy. Claiming substances intended for use, or capable of being used, as food or as medicine or drug Relating to substance prepared or produced by chemical processes (including Alloys, optical glass, semiconductor and inter-metallic compounds), no patent shall be granted in respect of claims for the substances themselves, but claims for the methods or processes of manufacture shall be patentable. The criteria under the US laws are also quite similar as above. Books, movies, and works of art cannot be patented, but protection is available for such items under the law of copyright.
Rights in a Patent
Patent registrations confers on the rightful owner a right capable of protection under the Act i.e. the right to exclude others from using the invention for a limited period of time. The monopoly over patented right can be exercised by the owner for a period of 20 years after which it is open to exploitation by others.
Patent confers the right to manufacture, use, offer for sale, sell or import the invention for the prescribed period.
Time Period for which Patent is granted
Initially, the Act provided for a shorter term pf protection for medicine or drug substances. However, vide the Amendment Act of 2005 uniform period of 20 years was provided for all the Patents. Thus, once the prescribed period of 20 years is over, then any person can exploit the patented invention. Here it would be relevant to mention that similar to a trademark even the term of a patent begins from the date of application of patent.
Requirements for Grant of Patent
- The application for Patent shall be made at the Indian Patent Office.
- Any person i.e. Indian or a Foreigner, individual, company or the Government can file a Patent Application.
- The person applying for Patent shall be the true and first inventor of the invention proposed to be patented.
- The patent application can also be made jointly.
- The patent application shall primarily disclose the best method of performing the invention known to the applicant for which he is entitled to claim protection.
- The applicant shall also define the scope of invention.
- The invention desired to be patented shall be- new, should involve an inventive step and must be capable of industrial application.
- A patent application can be made for a single invention only.
- An international application made under the PCT (Patent Co-operation Treaty) designating India shall be deemed as an application made under the Patents Act with the priority date accruing from the date of the international filing date accorded under the PCT.
Invention under the Patent Act
The Act under Section 2(1)(j) defines “invention” as a new product or process involving an inventive step capable of industrial application.
The term “industrial application” refers to capable of industrial application in relation to an invention means that the invention is capable of being made or used in an industry. One of the pre-requisite of invention is that it should be new i.e. the invention proposed to be patented has not been in the public domain or that it does not form part of the state of the art.
Under the Patent Act, both processes and products are entitled to qualify as inventions if they are new, involve an inventive step and are capable of industrial application.
Requirements to Qualify as Invention
- The Invention must be new
- Invention must involve an inventive step
- The invention must be capable of industrial application or utility;
- The invention shouldn’t come under the inventions which are not patentable under Section 3 and 4 of the Patent Act, 1970;
Non-patentable inventions are enumerated under Section 3 and 4 of the Patent Act. Such inventions are delineated below:
- Any Invention which is frivolous or which claims anything obviously contrary to well established natural laws is not patentable.
- Inventions which are contrary to public order or morality is not patentable.
- An idea or discovery cannot be a subject matter of a patent application.
- Inventions pertaining to known substances and known processes are not patentable i.e. mere discovery of a new form of a known substance which does not enhance the known efficacy of that substance is not patentable.
- An invention obtained through a mere admixture or arrangement is not patentable.
- A method of agriculture or horticulture cannot be subject matter of patent.
- A process involving medical treatment of human and animals or to increase their economic value cannot be subject matter of a patent.
- Plants and animals in whole or in part are not patentable.
- A mathematical or business method or a computer program per se or algorithms is excluded from patent protection.
- Matters that are subject matter of copyright protection like literary, dramatic, musical or artistic work is not patentable.
- Any scheme or rule.
- Presentation of information
- Topography of integrated circuits.
- Traditional knowledge.
- Inventions relating to atomic energy.
Infringement of Patent
Infringement of Patent primarily refers to intrusion or violation of the rights of a Patentee against which the Patentee has statutory rights under the Act.
The factors that are essential in determining infringement of a Patent are as under:
- While determining infringement it has to be assessed whether the infringing activity fell within the scope of the invention. Thus, the infringement has to be determined with regard to what has been claimed as invention under the Patent Act by applying the principles or standards of construction.
- To determine whether the infringing activity violated any statutory rights conferred to the Patentee under the Act. In this respect reference can be made to Section 48 of the Act which enumerates the rights of the Patentee with respect to a product patent and process patent.
- To determine the infringer i.e. the person liable for the infringement.
- To determine whether the infringing act fell within the acts which do not amount to infringement under the Patents Act i.e. excluded acts of Government use, use of patented product or process for experiment or research, import of medicine or drug by Government and patents in foreign vessels and aircrafts.
