The legal system of patents thus encourages inventions by promoting their protection and utilization so as to contribute to the development of industries, which in turn, contributes to the promotion of technological innovation and to the transfer and dissemination of information, knowledge and technology. In India, the rights conferred to the patentee have been enumerated in Section 48 of the Patents Act of 1970.(3) This law induces an inventor to disclose his invention to the whole world instead of keeping it as a secret. If the invention were to be kept a secret, then the inventor would be in constant fear of it being stolen by others. Such a disclosure not only makes the inventor famous, but also enables him to sell it to an industrial house and thereby gain economically. This object of the Patent Law thus provides a stimulus to others and also to industrial houses to carry out new inventions and discoveries.
Every country has its own Patent Laws and as such there is no “World Patent.” However, there is an international filing system that is in accordance with the Patent Cooperation Treaty (PCT). By virtue of this treaty, when a PCT application is filed in one of the member-states of the PCT it is tantamount to the filing of an application for the grant of patent in all PCT member states. The law in India which deals with patents is The Patents Act of 1970 (as amended by The Patents [Amendment] Act of 1999, The Patents [Amendment] Act of 2002 and The Patents [Amendment] Act of 2005).
India is a member of the following international organizations and treaties in respect to patents:
The Patents Act of 1970 specifically states that inventions relating to atomic energy(4) are not patentable and also categorically lays down that the following are not inventions within the meaning of the Act(5), namely -
a. an invention which is frivolous or which claims anything obviously contrary to well established natural laws;
b. an invention of which the primary or intended use would be contrary to law or morality or injurious to public health;
c. the mere discovery of a scientific principle or the formulation of an abstract theory;
d. the mere discovery of a new form of a known substance which does not result in the enhancement of the known efficacy of that substance or 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.
Explanation. – For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size, isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance unless they differ significantly in properties with regard to efficacy;(6)
e. 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;
f. the mere arrangement or rearrangement or duplication of known devices each functioning independently of one another in a known way;
g. a method or 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;
h. a method of agriculture or horticulture;
i. any process for the medicinal, surgical, curative, prophylactic or other treatment of human beings 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.
A close analysis of Clause (d) reveals that “trivial changes” in generic drugs are not eligible for patents. This provision, therefore, lays stress on innovation and hardcore research instead of tinkering with known substances.
An application for grant of a patent for an invention can be made under the Patents Act by any person claiming to be the true and first inventor of the invention, or by any person being the assignee of the person claiming to be the true and first inventor in respect of the right to make such an application, or by the legal representative of any deceased person who immediately before his death was entitled to make such an application.(7) The application for a patent has to be confined to only one invention and it has to be made in the prescribed form and filed in the patent office.
Although the essence of a patent is a conferring of the exclusive right on the patentee, the grant of the patent is subject to the following conditions, namely that(8)
After the grant of the patent, if it is found that the reasonable requirements of the public with respect to the patented invention have not been satisfied, or that the patented invention is not available to the public at a reasonably affordable price, or that the patented invention has not worked in India, then any person may make an application for grant of compulsory license after three years from the date of the sealing of a patent.(9) The issue of compulsory license of the said patent is subject to the conditions, namely (a) that the applicant pays to the patentee the royalty and other remuneration having regard to the nature of the invention, the expenditure incurred by the patentee in making the invention or in developing it and obtaining the patent; (b) that the patented invention is worked to the fullest extent by the applicant; and (c) that the patented articles are made available to the public at reasonable prices.(10)
In case of an infringement of a patent, the aggrieved patentee may file a suit in any District Court or a High Court having jurisdiction to entertain the suit. In such a suit, the aggrieved patentee viz., the plaintiff, will have to establish to the satisfaction of the court about the infringement of his patent by the defendant(s) i.e., the opposing party or parties, and upon doing so, he would be entitled to get an injunction order from the court which would restrain the defendant(s) from further infringing upon his patent rights. Normally in such a suit the plaintiff also seeks an “interim injunction” order from the court pending final decision, by making out a prima facie case and showing that the balance of convenience lies in his favor. Apart from seeking an injunction against the defendant(s), the plaintiff, in his suit for infringement, is also entitled to claim damages/compensation for the loss suffered by him as a result of the infringement of his patent. The plaintiff may also claim from the defendant(s) the profits made by them from the unauthorized use of his patent.(11)
From a bird’s eye view it would thus be noticed that in India the patent laws conform to global standards. This is due to the fact that as India is a member of the World Intellectual Property Organization (WIPO), an international organization responsible for the promotion of the protection of intellectual property throughout the world, its patents law has to comply with the TRIPS Agreement.(12)
