Overview of the Patents Act, 1970

Patents are one of the most important forms of intellectual property rights (IPRs). They provide inventors with legal protection for their inventions, allowing them to reap the benefits of their creativity and hard work. Without patents, inventors would have little incentive to disclose their inventions to the public, as others could freely copy and exploit their ideas.

In India, the law that governs patents is the Patents Act, 1970. This legislation has been the cornerstone of India’s patent system for more than five decades. It has gone through several amendments to meet changing social, economic, and technological needs, while also ensuring compliance with international obligations.

The Act plays a dual role. On one hand, it gives inventors exclusive rights to make, use, and sell their inventions. On the other, it ensures that innovation does not harm public welfare, especially in critical areas like healthcare and food. This balance between private rights and public interest is at the heart of the Indian patent system.

Historical Background of Patent Law in India

Early Developments

Patent protection in India can be traced back to the colonial era. The earliest law was Act VI of 1856, modelled on British law, which granted inventors exclusive privileges for 14 years. However, it was repealed within a year because it was enacted without the sanction of the British Crown.

In 1859, Act XV was passed, making modifications such as restricting the privileges to useful inventions and extending the priority period. Later, further amendments followed in 1872, 1883, and 1888.

The 1911 Act

The Indian Patents and Designs Act, 1911 consolidated earlier laws and governed patents in India for several decades. However, it was criticised because it largely benefited foreign firms and did little to encourage domestic innovation. For example, foreign pharmaceutical companies often used patents to control drug prices, which hurt Indian consumers.

Post-Independence Reforms

After independence, the need for a home-grown patent law became urgent. The Government appointed a committee in 1957 under Justice N. Rajagopala Ayyangar. The Ayyangar Committee Report recommended:

• Restricting product patents in critical areas like food and medicine, to prevent monopoly pricing.
• Encouraging process patents instead, so that Indian companies could develop cheaper alternatives.
• Balancing innovation with access to essential goods.

Based on these recommendations, the Patents Act, 1970 was enacted, replacing the 1911 Act. It came into effect on 20 April 1972 along with the Patent Rules, 1972.

Objectives of the Patents Act, 1970

The Act was framed with clear objectives, ensuring that innovation serves both inventors and society:

• Encouragement of scientific research: By granting exclusive rights, the Act motivates individuals and companies to invest in research and development.
• Protection of genuine inventions: Only inventions that are new, non-obvious, and useful receive patents.
• Balance of rights and duties: While patentees enjoy exclusive rights, provisions such as compulsory licensing ensure that the public is not deprived of essential goods.
• Prevention of abuse: The Act seeks to prevent monopolistic practices by limiting patent terms and excluding certain subject matters.
• Alignment with international standards: Amendments over time have ensured that India’s law complies with global frameworks like TRIPS while protecting national interest.

Definition of Patent

A patent is defined under Section 2(1)(m) as a patent granted for an invention. It is essentially an exclusive legal right, allowing the patentee to prevent others from making, using, selling, or importing the patented invention without permission. This exclusivity is limited to 20 years, after which the invention enters the public domain.

What is an Invention?

Under Section 2(1)(j), an invention is a new product or process involving an inventive step and capable of industrial application. To qualify:

• Novelty means that the invention must be entirely new. For example, if a research paper or product brochure has already disclosed the invention, it cannot be considered novel.
• Inventive step requires that the invention is not obvious to a person skilled in the same field. For instance, a minor change to an existing design that any trained engineer could think of will not qualify.
• Industrial application ensures that the invention can be practically used in an industry. Abstract ideas or purely theoretical models without application cannot be patented.

Patentable Inventions – Examples

• A pharmaceutical compound that provides a new treatment for cancer.
• A manufacturing process that reduces energy consumption by 40%.
• A mechanical device that increases productivity in textile industries.

Non-Patentable Inventions (Sections 3 and 4)

Certain subject matters are excluded from patentability:

• Mere discoveries: Natural substances like plants, minerals, or genes in their natural form are excluded.
• Scientific theories and mathematical methods: For example, the Pythagoras theorem or Einstein’s relativity theory cannot be patented.
• New forms of known substances without enhanced efficacy: Section 3(d) specifically prevents “evergreening” in pharmaceuticals, where companies make minor modifications to extend monopoly.
• Traditional knowledge: Well-known practices, such as neem’s use as a pesticide or turmeric’s healing properties, are excluded to protect cultural heritage.
• Atomic energy inventions: Section 4 bars patents related to atomic energy, considering national security.

Procedure for Obtaining a Patent in India

The procedure is designed to ensure thorough scrutiny of every application:

1. Filing of Application: The inventor or assignee files a provisional or complete specification with details of the invention, claims, and drawings. Provisional applications secure an early filing date.
2. Publication: After 18 months, applications are published in the Patent Journal, allowing the public to be aware of pending claims. Early publication is also possible.
3. Examination: A Request for Examination (RFE) must be filed. The Patent Office then examines the invention for novelty, inventive step, and industrial application. An examination report is issued.
4. Response and Hearing: The applicant responds to objections and may modify claims. If issues persist, a hearing is held before the Controller.
5. Grant of Patent: Once satisfied, the Controller grants the patent and publishes it in the Journal.
6. Opposition: Patents may be opposed before grant (pre-grant opposition) or within one year after grant (post-grant opposition). Grounds include lack of novelty, wrongful obtainment, or non-disclosure.
7. Term: The standard term is 20 years from filing. For PCT applications, the term starts from the international filing date.

Rights of Patentee

The Act grants patentees several exclusive rights:

• Right to exploit: The patentee can exclusively make, use, sell, or distribute the patented invention. For example, if a pharmaceutical company patents a drug, no one else can produce or sell it without consent.
• Right to license or assign: Patents can be licensed or transferred for consideration. This enables inventors who lack resources to commercialise their invention through others.
• Right to surrender: Patentees may voluntarily give up their patent by informing the Controller, who will notify interested parties.
• Right to sue for infringement: Patentees can file suits for damages or injunctions in case of unauthorised use.

Obligations of Patentee

Patent rights are not absolute; they come with duties:

• Working in India: Patents must be worked in India, meaning the invention should be manufactured locally rather than only imported.
• Government use: The Government can use patented inventions for public purposes, such as in hospitals, without permission from the patentee, though compensation is provided.
• Compulsory licensing: If the invention is not available to the public at affordable prices, or not sufficiently worked, the Controller may grant compulsory licenses. This ensures that public interest is protected.

What is Patent Infringement?

Patent infringement occurs when a person without authorisation makes, uses, sells, or imports a patented invention.

Types of Infringement

• Direct infringement: When the invention is copied exactly, such as manufacturing a patented drug without permission.
• Indirect infringement: When someone induces or assists others to infringe, such as supplying components solely made for a patented device.

2. Bayer Corporation v. Union of India (2014): Bayer’s drug Sorafenib was subject to India’s first compulsory licence, granted to Natco Pharma. The licence reduced drug prices drastically, highlighting the balance between patent rights and public health.
3. Biswanath Prasad Radhey Shyam v. Hindustan Metal Industries (1979): The Court clarified that minor workshop improvements or obvious changes do not qualify as inventive steps.
4. F. Hoffmann-La Roche Ltd. v. Cipla Ltd. (2008): The Delhi High Court addressed patent infringement related to an anti-cancer drug, balancing patent rights with the need for affordable healthcare.

Conclusion

The Patents Act, 1970 is the cornerstone of India’s intellectual property framework. It reflects India’s journey from a system favouring process patents to one aligned with global standards under TRIPS. At the same time, it preserves national interest through unique provisions like Section 3(d) and compulsory licensing.

Landmark cases such as Novartis and Bayer show how Indian courts have consistently balanced patent rights with public health. While the Act has encouraged innovation and foreign investment, challenges such as affordability of medicines and backlog of applications persist.
