Patent law has been formulated with an objective to promote and protect the inventions and methods. The object of granting a patent is to encourage and develop science, technology and industry.
A patent can be defined as a grant of exclusive rights to an inventor over his invention for a limited period of time. The exclusive rights conferred include the right to make, use, exercise, sell or distribute the invention in India. The term of a patent is twenty years, after the expiry of which, the invention would fall into the public domain.
History
In 1957, Govt. of India appointed Justice N. Rajagopala Ayyangar examine and review the Patent law in India who submitted his report September 1959 recommending the retention of Patent System despite shortcomings. The Patent Bill, 1965 based mainly on his recommendations incorporating a few changes, in particular relating to Patents for food, drug, medicines, was introduced in the lower house of Parliament on 21st September, 1965. The bill was passed by the Parliament and the Patents Act 1970 came into force on 20th April 1972 along with Patent Rules 1972. This law was suited changed political situation and economic needs for providing impetus technological development by promoting inventive activities in the country.
Uruguay round of GATT negotiations paved the way for WTO. Therefore India was put under the contractual obligation to amend its patents act in compliance with the provisions of TRIPS. India had to meet the first set of requirements on 1- 1-1995. This was to give a pipeline protection till the country starts giving product patent. It came to force on 26th March 1999 retrospective from 1-1-1995. It lays down the provisions for filing of application for product patent in the field of drugs or medicines with effect from 01.01.1995 and grant of Exclusive Marketing Rights on those products.
India amended its Patents Act again in 2002 to meet with the second set of obligations (Term of Patent etc.), which had to be effected from 1-1-2000. This amendment, which provides for 20 years term for the patent, Reversal of burden of proof etc. came into force on 20th May, 2003. The Third Amendment of the Patents Act 1970, by way of the Patents (Amendment) Ordinance 2004 came into force on 1st January, 2005 incorporating the provisions for granting product patent in all fields of Technology including chemicals, food, drugs & agrochemicals and this Ordinance is replaced by the Patents (Amendment) Act 2005 which is in force now having effect from 1-1-2005 .
ESTABLISHMENT OF PATENT ADMINISTRATION IN INDIA
Patent system in India is administered under the superintendence of the Controller General of Patents, Designs, Trademarks and Geographical Indications.
The Office of the Controller General functions under the Department of Industrial Policy and Promotion, Ministry of Commerce and Industry. There are four patent offices in India. The Head Office is located at Kolkata and other Patent Offices are located at Delhi, Mumbai and Chennai.

Patentable Inventions:
A patent can be granted for an invention which may be related to any process or product. The word “Invention ” has been defined under the Patents Act 1970 as amended from time to time.
“An invention means a new product or process involving an inventive step and capable of industrial application” (S. 2(1)(j))
” new invention” is defined as any invention or technology which has not been anticipated by publication in any document or used in the country or elsewhere in the world before the date of filing of patent application with complete specification, i.e. the subject matter has not fallen in public domain or that it does not form part of the state of the art; Where, Capable of industrial application, in relation to an invention, means that the invention is capable of being made or used in an industry
(S.2 (1)(ac)) Therefore, the criteria for an invention to be patentable are,
(1) An invention must be novel
(2) has an inventive step and
(3) is capable of industrial application
To be patentable, an invention should fall within the scope of patentable subject matter as defined by the patent statute. 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. With regard to medicine or drug and certain classes of chemicals no patent is granted for the product itself even if new, only the process of manufacturing the substance is patentable. However, product patents would be available for drugs and food materials from 2005 as India’s obligations under the TRIPs Agreement would kick in from that point of time. If any substance falls outside the scope of patentable subject matter, it cannot be patentable.
NOT PATENTABLE INVENTIONS
There are some products and processes, which are not patentable in India They are classified into two categories in the patent act
a) Those which are not inventions (S.3)
b) Invention relating to atomic Energy (S.4)
Various types of non-patentable inventions under Section 3 are as follows-
3(a) An invention which is frivolous or which claims anything obvious contrary to well established natural laws.
Merely making in one piece, articles, previously made in two or more pieces is frivolous. Mere usefulness is not sufficient (Indian vacuum brake co. ltd vs. Laurd (AUR 1962 CAK 152).
Perpetual motion machine alleged to be giving output without any input is not patentable as it is contrary to natural law.
3(b) An invention the primary or intended use or commercial exploitation of which could be contrary to public order or morality or which causes serious prejudice to human, animal or plant life or health or to the environment
3(c) The mere discovery of a scientific principle or the formulation of an abstract theory or discovery of any living thing or non-living substances occurring in nature;
3(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.
[Note: Before amendment of Section 3 (d) by the Patents (Amendments) Ordinance 2004 it reads as “mere discovery of any new property or new use for a known substance or mere use of a known process, machine or apparatus
”The insertion of the word “mere” before ‘new use for a known substance’ in this clause by the Patents (Amendment) Ordinance 2004, is for the purpose of drafting clarity only as without it the sub-section would have remained ambiguous. This does not restrict the nonpatentability and give rise to ambiguity and possible misuse. There is no
need of giving wider meaning to it.]
3(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:
3(f) The mere arrangement or re-arrangement or duplication of known devices each
functioning independently of one another in a known way.
3(h) A method of agriculture or horticulture.
(i) A method of producing a new form of a known plant even if it involved a modification of the conditions under which natural phenomena would pursue their inevitable course is not patentable. (N.V. Philips Gloeiammpenfabrieken’s Application 71 RFC 192).
3(i) Any process for the medicinal, surgical, curative, prophylactic diagnostic therapeutic or other treatment of human being or any process for a similar treatment of animals to render them free of disease or to increase their economic value or that of their products.
Plants and animals in whole or any part thereof other than microorganisms but including seeds, varieties and species and essentially biological processes for production or propagation of plants and animals;
Example: Clones and new variety of plants are not patentable. But process / method of preparing Genetically Modified Organisms are patentable subject matter.
3(m) A mere scheme or rule or method of performing mental act or method of playing game;
3(n) A presentation of information
3(o) Topography of integrated circuits;
INVENTIONS RELATING TO ATOMIC ENERGY (S.4)
