1. Introduction and Meaning of Intellectual Property
Intellectual Property Rights (IPR) are legal rights that protect the interests of creators and inventors by granting them exclusive rights over their creations for a specified period. These rights enable innovators to benefit commercially from their work and encourage continued innovation and creativity in society.
The fundamental objectives of IPR include:
- Promoting innovation and creativity by providing economic incentives
- Protecting the interests of creators and inventors
- Facilitating technology transfer and dissemination of knowledge
- Encouraging fair competition in the marketplace
- Contributing to economic and social development
2. Types of Intellectual Property
2.1 Patents
Patents protect new inventions and provide exclusive rights to the inventor to make, use, sell, or distribute the invention for a limited period (typically 20 years from filing date). Patents cover technological innovations, processes, machines, compositions of matter, and improvements thereof.
2.2 Copyrights
Copyright protects original literary, artistic, musical, and dramatic works, including books, music, paintings, sculptures, films, and computer software. It grants the creator exclusive rights to reproduce, distribute, perform, display, or license their work. Copyright protection typically lasts for the lifetime of the author plus 60 years in India.
2.3 Trademarks
A trademark is a distinctive sign, symbol, word, phrase, logo, or combination thereof that identifies and distinguishes goods or services of one enterprise from those of others. Trademarks help consumers identify the source of products and build brand reputation. Protection is renewable indefinitely as long as the mark is in use.
2.4 Industrial Designs
Industrial designs protect the aesthetic or ornamental aspects of an article. A design may consist of three-dimensional features (shape or surface) or two-dimensional features (patterns, lines, or colors). Protection typically lasts for 15 years in India.
2.5 Geographical Indications (GI)
Geographical indications identify goods as originating from a specific geographical location where a given quality, reputation, or characteristic is essentially attributable to that origin. Examples include Darjeeling Tea, Basmati Rice, and Kanchipuram Silk.
2.6 Integrated Circuits
Also known as semiconductor integrated circuits layout-designs, these protect the three-dimensional configuration of electronic circuits embedded in semiconductor integrated circuits or layout-designs. Protection encourages innovation in the semiconductor industry.
2.7 Trade Secrets
Trade secrets are confidential business information that provides a competitive advantage. This includes formulas, practices, processes, designs, instruments, or compilations of information. Unlike other IP rights, trade secrets have no time limit but require the owner to take reasonable steps to maintain secrecy.
3. Legislations Covering IPR in India
India has a comprehensive legal framework for protecting intellectual property rights:
| Type of IP | Legislation | Administering Authority |
|---|---|---|
| Patents | The Patents Act, 1970 (amended 2005) | Office of the Controller General of Patents, Designs and Trade Marks |
| Copyrights | The Copyright Act, 1957 | Copyright Office, Department of Industrial Policy and Promotion |
| Trademarks | The Trade Marks Act, 1999 | Trade Marks Registry |
| Industrial Designs | The Designs Act, 2000 | Office of the Controller General of Patents, Designs and Trade Marks |
| Geographical Indications | The Geographical Indications of Goods (Registration and Protection) Act, 1999 | Geographical Indications Registry |
| Integrated Circuits | The Semiconductor Integrated Circuits Layout-Design Act, 2000 | Semiconductor Integrated Circuits Layout-Design Registry |
| Trade Secrets | Common Law and Contract Law | Courts |
4. The Patents Act, 1970 and Patent System in India
4.1 Historical Background
The Patents Act, 1970, came into force on April 20, 1972, replacing the Indian Patents and Designs Act, 1911. The Act was a result of the recommendations of the Justice N. Rajagopala Ayyangar Committee and aimed to balance the interests of inventors with public interest, particularly in crucial sectors like pharmaceuticals and agriculture.
Significant amendments were made in 1999, 2002, and 2005 to comply with the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). The 2005 amendment was particularly important as it reintroduced product patents in all fields of technology, including pharmaceuticals and agrochemicals.
4.2 Patent System Administration
The Indian patent system is administered by the Office of the Controller General of Patents, Designs and Trade Marks (CGPDTM), which operates under the Department for Promotion of Industry and Internal Trade (DPIIT). There are four patent offices located in:
- Kolkata (serving West Bengal, Assam, Bihar, Jharkhand, Odisha, and other northeastern states)
- Delhi (serving Delhi, Haryana, Himachal Pradesh, Jammu & Kashmir, Punjab, Rajasthan, Uttar Pradesh, Uttarakhand, and Chandigarh)
- Mumbai (serving Gujarat, Maharashtra, Madhya Pradesh, Chhattisgarh, and Goa)
- Chennai (serving Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, Telangana, and Puducherry)
5. Patentability
5.1 Criteria for Patentability
Under Section 2(1)(j) of the Patents Act, an invention must satisfy three essential criteria to be patentable:
a) Novelty
The invention must be new and not anticipated by prior publication, prior knowledge, or prior use. It should not form part of the "state of the art," which includes everything made available to the public anywhere in the world before the filing date.
b) Inventive Step (Non-Obviousness)
The invention must involve technical advancement or economic significance or both, making it non-obvious to a person skilled in the art. It should not be an obvious combination of existing knowledge.
c) Industrial Application
The invention must be capable of being made or used in an industry. It should have practical utility and be capable of industrial application.
5.2 What Cannot be Patented (Section 3 and 4)
The Patents Act explicitly excludes certain categories from patentability:
- Frivolous inventions or those contrary to natural laws
- Inventions that are contrary to public order, morality, or cause harm to human, animal, or plant life
- Mere discovery of a scientific principle or abstract theory
- Discovery of any living thing or non-living substance occurring in nature
- Methods of agriculture or horticulture
- Medical treatment methods for humans and animals (diagnostic, therapeutic, or surgical)
- Plants and animals in whole or in part (except microorganisms)
- Mathematical methods, business methods, or computer programs per se
- Aesthetic creations, literary works, or mere arrangements of information
- Traditional knowledge or aggregation of known properties of components
6. Process Patent and Product Patent
6.1 Product Patent
Product patents provide stronger protection as they cover the end product in all its forms and manufactured through any process. This is particularly important in pharmaceuticals, where a single drug can be manufactured through various methods.
6.2 Process Patent
Prior to 2005, India only recognized process patents for pharmaceuticals and agrochemicals. The 2005 amendment introduced product patents in all fields of technology, aligning India with international standards under TRIPS.
6.3 Comparison
| Aspect | Product Patent | Process Patent |
|---|---|---|
| Protection | Covers the product itself | Covers the manufacturing method |
| Scope | Broader protection | Narrower protection |
| Circumvention | Difficult to circumvent | Can be circumvented by alternate processes |
| Duration | 20 years from filing | 20 years from filing |
