Fourth-year Law Notes & Flashcards

Overview of Patent Law in India: The Patents Act, 1970

Introduction

Patents form one of the most important components of intellectual property rights. They provide inventors with legal protection for their inventions by granting them exclusive rights over the use and commercial exploitation of their creations for a specific period. The purpose of patent law is to encourage innovation and technological advancement by rewarding inventors for their creativity, effort, and investment in research and development. Without such protection, inventors might hesitate to disclose their inventions to the public because others could easily copy and exploit them without compensation.

In India, patent protection is governed by the Patents Act, 1970, which has been the backbone of India’s patent regime for more than fifty years. The Act was enacted to replace earlier colonial legislation and to establish a patent system suited to the needs of an independent and developing nation. It came into force on 20 April 1972, along with the Patent Rules, 1972.

The Act seeks to maintain a delicate balance between two important goals. On one hand, it grants inventors exclusive rights to make, use, sell, or license their inventions. On the other hand, it safeguards public interest by ensuring that such rights do not lead to monopolistic practices that could harm society, particularly in areas like medicine, food, and essential technologies. Through provisions such as compulsory licensing and restrictions on certain patents, the Act ensures that innovation benefits both inventors and the public.

Historical Background of Patent Law in India

Early Developments

Patent law in India originated during the colonial period when the British administration introduced legal frameworks similar to those existing in England. The first legislation relating to patents in India was Act VI of 1856, which granted inventors exclusive privileges for their inventions for a period of fourteen years. However, this Act was repealed within a year because it had been enacted without proper approval from the British Crown.

Subsequently, Act XV of 1859 was introduced, which modified the earlier law and restricted patent privileges only to useful inventions. It also introduced the concept of priority rights. Later amendments were enacted in 1872, 1883, and 1888, gradually shaping the early patent system in India.

The 1911 Act

A major development occurred with the enactment of the Indian Patents and Designs Act, 1911, which consolidated earlier laws relating to patents and industrial designs. This Act governed patent protection in India for several decades. However, it was widely criticised because it largely benefited foreign companies rather than encouraging domestic innovation.

For example, multinational pharmaceutical companies used patent protection to maintain monopolies over essential medicines, often resulting in high prices that were unaffordable for Indian consumers.

Post-Independence Reforms

After India gained independence, it became necessary to develop a patent system that would promote domestic innovation and serve national interests. In 1957, the Government appointed a committee headed by Justice N. Rajagopala Ayyangar to review the existing patent law.

The committee recommended several important reforms, including restricting product patents in essential sectors such as pharmaceuticals and food and encouraging process patents instead. This would allow Indian manufacturers to develop alternative manufacturing processes and produce cheaper versions of essential goods.

Based on these recommendations, the Patents Act, 1970 was enacted, replacing the 1911 Act and creating a modern patent system suited to India’s developmental needs.

Objectives of the Patents Act, 1970

The Patents Act was enacted with several key objectives aimed at promoting innovation while protecting public interest.

One of the primary objectives is to encourage scientific research and technological innovation. By granting inventors exclusive rights over their inventions, the Act motivates individuals, researchers, and companies to invest time and resources in developing new technologies.

Another objective is to protect genuine inventions. The law ensures that patents are granted only for inventions that are new, involve an inventive step, and are capable of industrial application.

The Act also aims to balance private rights with public welfare. While inventors receive exclusive rights, the law includes provisions such as compulsory licensing to ensure that essential products remain accessible to the public at affordable prices.

Additionally, the Act seeks to prevent abuse of patent rights by limiting the duration of patents and excluding certain subject matters from patentability.

Finally, the Act has been amended to ensure compliance with international agreements, particularly the TRIPS Agreement, while still protecting India’s national interests.

Definition of Patent

A patent is defined under Section 2(1)(m) of the Patents Act, 1970 as a patent granted for an invention. In simple terms, it is an exclusive legal right granted by the government to an inventor, allowing them to prevent others from making, using, selling, or importing the patented invention without permission.

This exclusive right is granted for a limited period of 20 years, after which the invention becomes part of the public domain and can be freely used by anyone.

For example, if a scientist develops a new pharmaceutical drug and obtains a patent, no other company can manufacture or sell that drug without obtaining permission or a licence from the patent holder during the patent term.

What is an Invention?

Under Section 2(1)(j) of the Act, an invention is defined as a new product or process involving an inventive step and capable of industrial application.

The first requirement is novelty, which means that the invention must be new and must not have been previously disclosed anywhere in the world.

The second requirement is inventive step, meaning the invention should not be obvious to a person skilled in the relevant field. It should involve a technical advancement or significant improvement over existing knowledge.

The third requirement is industrial applicability, which means that the invention must be capable of being used in some form of industry.

For example, a machine that reduces electricity consumption in factories or a new drug formulation for treating diseases may qualify as inventions if they satisfy these criteria.

Patentable and Non-Patentable Inventions

Many inventions qualify for patent protection, such as innovative pharmaceutical compounds, mechanical devices, manufacturing processes, and technological products.

For instance, a pharmaceutical company may develop a new chemical compound that effectively treats cancer, or an engineer may invent a machine that increases productivity in textile manufacturing.

However, certain subject matters are specifically excluded from patentability under Sections 3 and 4 of the Act.

These include mere discoveries of natural substances, such as plants or minerals found in nature. Scientific theories and mathematical methods are also excluded. For example, Einstein’s theory of relativity cannot be patented because it is a scientific discovery rather than an invention.

Another important exclusion is found in Section 3(d), which prevents pharmaceutical companies from obtaining patents for minor modifications of existing drugs without significant improvement in therapeutic efficacy. This provision aims to prevent the practice known as “evergreening.”

Traditional knowledge is also excluded from patent protection. For example, the well-known medicinal properties of turmeric or neem cannot be patented because they are part of India’s traditional knowledge system.

Additionally, inventions relating to atomic energy are excluded from patentability due to national security concerns.

Procedure for Obtaining a Patent in India

The process of obtaining a patent in India involves several stages designed to ensure careful examination of every application.

The first step is filing a patent application with the Patent Office. The inventor may file a provisional specification to secure an early filing date, followed by a complete specification within twelve months.

After filing, the application is published in the Patent Journal after eighteen months, making it available for public inspection.

Next, the applicant must file a Request for Examination, after which the Patent Office examines the application to determine whether it satisfies the requirements of novelty, inventive step, and industrial applicability.

If objections are raised, the applicant must respond to them or modify the claims. In some cases, a hearing may be conducted before the Controller of Patents.

Once the Controller is satisfied, the patent is granted and published. However, the patent may still be challenged through pre-grant or post-grant opposition by interested parties.

Rights of the Patentee

The Act grants several exclusive rights to patent holders.

The patentee has the right to exploit the invention, meaning they can manufacture, use, sell, or import the patented product.

They also have the right to license or assign the patent, allowing others to use the invention in exchange for royalties or other financial benefits.

Additionally, patentees have the right to take legal action for infringement if someone uses their invention without permission.

For example, if a company produces a patented drug without authorization, the patent holder can file a lawsuit seeking damages and an injunction.

Obligations of the Patentee

While patentees enjoy exclusive rights, they also have certain obligations.

One important requirement is that the patent must be worked in India, meaning that the invention should be commercially exploited within the country rather than merely imported.

The government also has the power to use patented inventions for public purposes, particularly in situations involving national emergencies or public health.

Furthermore, the Act allows the grant of compulsory licences when the patented invention is not available to the public at reasonable prices or when the patent holder fails to adequately work the invention in India.

Patent Infringement

Patent infringement occurs when a person or company uses a patented invention without the authorization of the patent holder.

Infringement may take different forms. Direct infringement occurs when someone manufactures or sells the patented product without permission.

Indirect infringement occurs when a person supplies components or encourages others to infringe a patent.

In such cases, the patent holder can approach the court seeking remedies such as injunctions, damages, or accounts of profits.

Important Amendments to the Patents Act

The Patents Act, 1970 has undergone several amendments to align with international standards and technological advancements.

The 1999 amendment introduced the mailbox system for filing pharmaceutical and agrochemical patents and allowed Exclusive Marketing Rights.

The 2002 amendment extended the patent term to twenty years and strengthened provisions relating to compulsory licensing and opposition.

The 2005 amendment was particularly significant because it introduced product patents in all fields of technology, including pharmaceuticals and chemicals, thereby bringing India’s patent law in compliance with the TRIPS Agreement.

Later amendments, including the 2016 and 2021 rules, introduced digital filing systems, expedited examination for start-ups, and greater transparency in patent procedures.

Landmark Case Laws

Indian courts have played an important role in interpreting patent law.

In Novartis AG v. Union of India, MANU/SC/0281/2013

Novartis AG vs. Union of India (UOI) and Ors. (01.04.2013 - SC) : MANU/SC/0281/2013 the Supreme Court refused to grant a patent for the cancer drug Glivec because the modification did not significantly improve its therapeutic efficacy. This judgment reinforced Section 3(d) and ensured access to affordable medicines.

Another important case is Hindalco Industries Limited vs. Union of India and Ors. (20.12.2012 - JHRHC) : MANU/JH/1865/2012 where India granted its first compulsory licence for the cancer drug Sorafenib. The licence allowed an Indian company to manufacture a cheaper version of the drug, dramatically reducing its price.

In Bishwanath Prasad Radhey Shyam vs. Hindustan Metal Industries (13.12.1978 - SC) : MANU/SC/0255/1978 the Supreme Court clarified that minor mechanical improvements or workshop modifications do not qualify as inventions.

Conclusion

The Patents Act, 1970 forms the foundation of India’s patent system and plays a crucial role in promoting innovation and technological progress. By granting inventors exclusive rights over their inventions, the Act encourages research and development across various industries.

At the same time, the law incorporates safeguards to ensure that patent protection does not harm public welfare. Provisions such as compulsory licensing and restrictions on evergreening demonstrate India’s commitment to balancing private intellectual property rights with public interest.

With the rapid growth of technology, biotechnology, artificial intelligence, and pharmaceuticals, patent law continues to evolve. Future reforms will need to address emerging challenges while maintaining the delicate balance between encouraging innovation and ensuring equitable access to technological advancements.
