Non-Patentable Inventions in India

We will delve into the world of non-patentable inventions in India under the Indian patent law. Understanding the specific exceptions and criteria is essential for inventors and businesses seeking intellectual property protection for their innovations.

Section 3(a): Frivolous Inventions or Inventions Contrary to Well-Established Natural Laws

Section 3(a) of the Indian Patent Act states that an invention is non-patentable if it is frivolous, or if it claims anything that is obviously contrary to well-established natural laws.

Example 1: A Perpetual Motion Machine

A device that claims to generate perpetual motion, in violation of the laws of thermodynamics, is non-patentable in India as it contradicts well-established natural laws.

Example 2: A Time Travel Device

A device that claims to enable time travel, which contradicts the fundamental principles of physics, is non-patentable in India as it goes against well-established natural laws.

Section 3(b): Inventions Contrary to Public Order and Morality

Any invention that is considered contrary to public order or morality, or that could harm human, animal, or plant life, is non-patentable under Section 3(b) of the Indian Patent Act.

Example 1: A Weapon of Mass Destruction

A new technology designed to create weapons of mass destruction would not be eligible for a patent in India, as it is considered contrary to public order and morality.

Example 2: A Genetically Modified Organism with Harmful Effects

A genetically modified organism that poses a significant threat to human health or the environment is non-patentable in India, as it goes against public interest and morality.

Section 3(c): Mere Discovery of a Scientific Principle or Formulation

The mere discovery of a scientific principle or formulation of an abstract theory is non-patentable under Section 3(c) of the Indian Patent Act.

Example 1: A New Scientific Principle

If a scientist discovers a new principle governing the behavior of a natural phenomenon, it cannot be patented in India, as it is considered a mere discovery.

Example 2: A Formulation of an Abstract Theory

An abstract theory or concept, such as a new mathematical theorem or an innovative business strategy, is non-patentable in India, as it falls under the category of mere discovery.

Section 3(d): Derivatives of Known Substances

Section 3(d) of the Indian Patent Act states that a new form of a known substance, which does not result in the enhancement of the known efficacy of that substance, is non-patentable. In other words, for a new form of a known substance to be patentable, it must demonstrate a significant improvement in its efficacy compared to the original substance. This is particularly relevant in the pharmaceutical industry, where the development of new forms of known drugs, such as salts, esters, and polymorphs, is commonplace.

Example 1: A New Salt of a Known Drug

Suppose a pharmaceutical company develops a new salt form of a known drug. This new salt form exhibits similar therapeutic efficacy as the original drug, but it has improved solubility and absorption. In this case, the new salt form would not be patentable under Section 3(d) of the Indian Patent Act, as the improved solubility and absorption do not directly translate into enhanced therapeutic efficacy.

Example 2: A Polymorph of a Known Drug

A pharmaceutical company discovers a new polymorph of a known drug. A polymorph is a different crystalline form of the same compound, which can exhibit different physical properties, such as solubility and stability. If the new polymorph does not demonstrate a significant improvement in therapeutic efficacy compared to the original form, it would be considered non-patentable under Section 3(d).

Implications of Section 3(d) for the Pharmaceutical Industry

Section 3(d) plays a crucial role in preventing the practice of "evergreening" in the pharmaceutical industry. Evergreening is a strategy used by some pharmaceutical companies to extend the patent life of their products by making minor modifications to the original compound without significant improvements in efficacy. By imposing strict criteria for patentability under Section 3(d), the Indian Patent Act ensures that only genuinely innovative pharmaceutical inventions receive patent protection.

Furthermore, Section 3(d) promotes the availability of affordable generic drugs in the Indian market by limiting the patentability of minor modifications to known drugs. This helps maintain a balance between promoting innovation in the pharmaceutical sector and ensuring access to essential medicines for the Indian population.

Section 3(d) of the Indian Patent Act plays a critical role in shaping the landscape of pharmaceutical innovation in India. By setting stringent criteria for the patentability of new forms of known substances, it encourages genuine innovation while safeguarding public health interests.
