INTELLECTUAL PROPERTY LAW UNIT –V Patent Act 1970

A patent can turn an invention into a legally protected asset, but only if the invention meets the law’s tests and the inventor follows the correct filing process. In India, patent rights come mainly from the Patents Act, 1970, as amended to meet India’s policy goals and its international obligations under the World Trade Organization’s TRIPS Agreement.

This guide explains the concept of patents, the history of Indian patent law, patentable inventions, types of patent applications, the procedure for obtaining a patent, and the rights and limits that apply after grant.

The Patent Act of 1970 forms the backbone of intellectual property protection in India. It governs how inventions are protected, encouraging innovation while balancing public interest. Understanding the major topics within this law is essential for inventors, businesses, legal professionals, and anyone interested in how new ideas gain legal recognition. This article breaks down the core concepts of the Patent Act 1970, including what patents are, their objectives, and the boundaries of patentability.Patents play a crucial role in protecting inventions and encouraging innovation. For inventors and businesses in India, understanding what a patent is, which inventions qualify for patent protection, and the process to obtain a patent is essential. This post explores these topics in detail, focusing on the Indian patent system, the rights and responsibilities of patentees, and the types of inventions that cannot be patented.

The concept of a patent and how Indian patent law developed

A patent is a statutory right granted by the government to an inventor or applicant. It gives the patentee the right to stop others from making, using, selling, offering for sale, or importing the patented invention without permission.

In return, the inventor must disclose the invention to the public in a patent specification. This bargain is central to patent law. Society gets technical knowledge. The inventor gets a limited monopoly.

Under the Patents Act, 1970, an invention generally must satisfy three core requirements:

• Novelty - The invention must be new. It should not already be known through earlier publications, use, or public disclosure.

• Inventive step - The invention must involve technical advancement or economic significance, and it must not be obvious to a person skilled in that field.
• Industrial application - The invention must be capable of being made or used in an industry.

A short historical overview of patent law in India

Patent law in India has developed in stages.

During British rule, India had early patent-related laws in the nineteenth century. Later, the Indian Patents and Designs Act, 1911 governed patents and designs for several decades.

After independence, India reviewed whether patent law served national development. Two major committee reports shaped the debate, including the Justice N. Rajagopala Ayyangar Committee report. The result was the Patents Act, 1970, which came into force in 1972.

The 1970 Act reflected India’s public interest priorities. For example, it did not allow product patents for food, medicines, and chemical substances in the same way modern law does. It allowed only process patents in those areas. This helped Indian pharmaceutical companies produce medicines using alternative processes.

India later joined the WTO and became bound by the TRIPS Agreement. To comply, India amended its patent law in phases:

Amendment	Main effect
1999 amendment	Introduced mailbox applications and Exclusive Marketing Rights for certain products
2002 amendment	Changed the patent term to 20 years and updated definitions such as inventive step
2005 amendment	Restored product patents for all fields of technology, including pharmaceuticals and agrochemicals
Later rule changes	Added procedural reforms such as e-filing, expedited examination for eligible applicants, and changes in patent prosecution practice

The 2005 amendment was especially important because it aligned Indian law with TRIPS by allowing product patents in pharmaceuticals, while keeping safeguards such as compulsory licensing and restrictions on evergreening.

Kinds of patents and patent applications in India

India grants patents under one main patent system. Unlike some countries, India does not have a separate “utility patent” system. Designs are protected separately under design law, not as design patents under the Patents Act.

Still, different kinds of patent applications can be filed depending on the situation.

Ordinary application - An ordinary application is filed directly in India when the applicant does not claim priority from an earlier foreign application.

Convention application - A convention application claims priority from an application filed in a convention country. India follows the Paris Convention framework. The applicant must file within the prescribed priority period, commonly 12 months from the first filing.

PCT national phase application - The Patent Cooperation Treaty allows an applicant to file an international application and later enter national phases in selected countries. For India, the applicant must enter the Indian national phase within the prescribed time limit.

Divisional application - A divisional application is used when the original application contains more than one invention. The applicant may divide the application so that each application claims a distinct invention.

Patent of addition - A patent of addition protects an improvement or modification of an invention already covered by a main patent. It is linked to the main patent and usually expires with it.

What Is an Invention?

An invention is a new and useful product, process, machine, or improvement that offers a novel solution to a problem. It can be a device, method, composition of matter, or any new technology that has practical utility. The key aspect of an invention is its novelty and usefulness, which distinguishes it from existing knowledge or products.

Patentable vs. Non-Patentable Inventions

Not all inventions qualify for patent protection. In India, the law specifies which inventions can be patented and which cannot. Generally, inventions that are new, involve an inventive step, and are capable of industrial application are patentable.

Examples of patentable inventions include:

• New chemical compounds or pharmaceuticals
• Innovative mechanical devices
• Software-related inventions with technical effect
• Biotechnology inventions

Inventions that are not patentable include:

• Discoveries of scientific principles or natural phenomena
• Abstract ideas, mental processes, or business methods without technical application
• Mere schemes, rules, or methods for performing mental acts or playing games
• Inventions contrary to public order, morality, or health
• Plants and animals other than microorganisms
• Traditional knowledge or inventions already known to the public

What Is a Patent?

A patent is a legal right granted by the government to an inventor, giving exclusive rights to make, use, sell, or license the invention for a limited period, usually 20 years from the filing date. This right prevents others from exploiting the invention without the patentee’s permission.

The patent system encourages innovation by rewarding inventors with a temporary monopoly, allowing them to recover research and development costs and profit from their creativity.

Inventions Not Patented in India

• India’s patent law excludes certain inventions from patent protection to balance public interest and innovation. These include:
• Inventions that are frivolous or contrary to well-established natural laws
• Methods of agriculture or horticulture
• Medical treatments or surgical methods for humans or animals
• Inventions related to atomic energy
• Software per se without technical application
• This list ensures that patents do not hinder access to essential knowledge or ethical standards.

Procedure for Obtaining a Patent in India

Obtaining a patent involves several steps, each requiring careful attention to legal and technical details.

Step 1: Patent Search

Before filing, conduct a patent search to check if the invention is novel. This involves searching existing patents, scientific literature, and public disclosures.

Step 2: Filing the Patent Application

The application can be filed with the Indian Patent Office either online or physically. It must include:

• A detailed description of the invention
• Claims defining the scope of protection sought
• Abstract summarizing the invention
• Drawings, if applicable
• Applicant’s and inventor’s detail

Step 3: Publication of Application

After 18 months from the filing date, the application is published in the Patent Journal, making the invention public.

Step 4: Request for Examination

The applicant must request examination within 48 months of filing. The patent office then reviews the application for compliance with patentability criteria.

Step 5: Examination Report and Response

The patent office issues a First Examination Report (FER) highlighting objections or requirements. The applicant must respond with clarifications, amendments, or arguments.

Step 6: Grant or Refusal of Patent

If the application meets all requirements, the patent is granted and published in the Patent Journal. If not, the application may be refused.

Step 7: Post-Grant Opposition

Third parties can oppose the patent within one year of grant, citing reasons why the patent should not have been granted.

THE INDIAN PATENTS ACT 1970

The Indian patents act 1970 provides with regards to patents. section 41 of the patents act 1970 excludes inventions in the field of atomic energy as falling within section 20(1) of the atomic energy act 1922 from the ambit of the patent law. the issue as to whether a particular invention relates to atomic energy is left to the discretion of the central government the invention in the field of atomic energy, therefore, are non -patentable under the Indian patent law

Rights and Obligations of a Patentee

Once granted, a patent confers several rights and responsibilities.

• Rights of the Patentee
• Exclusive right to make, use, sell, or license the invention in India
• Right to prevent others from unauthorized use
• Ability to assign or transfer the patent rights
• Right to sue for infringement and claim damages

Obligations of the Patentee

• Pay annual renewal fees to keep the patent in force
• Work the patent in India, meaning the invention should be used or manufactured locally to avoid compulsory licensing
• Disclose any improvements or related inventions
• Maintain accurate records and respond to legal challenges
• Failure to meet obligations can lead to patent revocation or compulsory licensing.

Essential Documents for Patent Application

• A potential patentee must prepare and submit several key documents:
• Patent Specification: Detailed description and claims of the invention
• Provisional or Complete Application: Depending on the stage of invention development
• Drawings: Visual representations if necessary
• Form 1: Application for grant of patent
• Form 2: Provisional/Complete specification
• Form 3: Statement and undertaking regarding foreign applications
• Form 5: Declaration as to inventorship
• Form 26: Power of attorney if filed through a patent agent
• Priority documents: If claiming priority from an earlier application
• Accurate and complete documentation is critical to avoid delays or rejection.

Conditions for Grant of Patent in India

To be granted a patent, an invention must satisfy these conditions:

• Novelty: The invention must be new and not disclosed anywhere in the world before the filing date.
• Inventive Step: The invention should not be obvious to a person skilled in the relevant field.
• Industrial Applicability: The invention must be capable of being made or used in an industry.
• Patentable Subject Matter: The invention must fall within the categories allowed by Indian patent law.
• Disclosure: The application must fully disclose the invention so others can reproduce it.

Key takeaway

Indian patent law protects genuine technical inventions, but it also sets clear limits. The Patents Act, 1970 rewards novelty and inventive skill, requires public disclosure, gives protection for 20 years, and allows enforcement against infringers. At the same time, it keeps public interest safeguards through exclusions, opposition, secrecy rules, compulsory licensing, and limits on abusive use of patent rights.

A strong patent strategy starts before filing. The invention must be properly searched, drafted, claimed, and prosecuted with care. Once granted, the patent must be renewed, worked responsibly, and enforced within the boundaries of Indian law.
