Section 3 of the Indian Patent Act
Non-Patentable Subject Matter
•Purpose of Section 3: Defines boundaries of
patentability to protect public interest and prevent
misuse.
•Scope: Lists specific categories of inventions
excluded from patent protection.
•Significance: Ensures patents are granted only for
genuine innovation, not for natural phenomena or
traditional knowledge.

Understanding Section 3
The Rationale Behind Exclusions
Preventing Abuse
Exclusions ensure patents are not
granted for trivial, harmful, or
unethical claims.
Protecting Commons
Keeps essential knowledge such as
natural laws, agriculture, and
traditional wisdom in the public
domain.
Encouraging Genuine Innovation
Directs patent protection toward real
technological advances that benefit
society.
Clause 3(a)
Frivolous Inventions or Contrary to Natural Laws
Scope
Prohibits patents for inventions that
are physically impossible or violate
natural laws.
Examples
Perpetual motion machines, faster-
than-light travel devices.
Rationale
Ensures patent law does not endorse
pseudoscience or impossibilities.
Clause 3(b)
Inventions Contrary to Public Order or Morality, Harmful Use
•Moral & Ethical Boundaries: Excludes inventions
that threaten public order, morality, or safety.
•Harmful Applications: Covers weapons of mass
destruction, harmful chemicals, or exploitative
technologies.
•Policy Rationale: Protects society by ensuring
patents do not legitimize dangerous or immoral
practices.

Clause 3(c)
Mere Discovery of Natural Principles or Substances
•Exclusion Scope: Discovering natural laws,
substances, or minerals does not qualify as
invention.
•Examples: Discovery of a new plant species or
mineral is not patentable unless applied in a novel
process.
•Policy Rationale: Keeps naturally occurring
phenomena in the public domain for all to use.

Clause 3(d)
New Forms or Uses of Known Substances Without Enhanced Efficacy
Evergreening Prevention
Prevents pharmaceutical companies
from extending monopolies by
making minor modifications.
Efficacy Requirement
New forms or uses must
demonstrate significant
enhancement in therapeutic efficacy.
Landmark Example
Novartis v. Union of India (2013)
upheld strict standards for drug
patents.
Clause 3(e)
Mere Admixture
Exclusion Scope
Simple admixture of known
substances that does not produce
synergistic effect is not patentable.
Examples
Mixing two known drugs or
chemicals without enhanced efficacy.
Rationale
Encourages only innovative
combinations with new properties or
effects.
Clause 3(f)
Mere Arrangement or Duplication of Devices
•Exclusion Scope: Simple arrangement or
duplication of known devices performing
independent functions is not patentable.
•Examples: A bucket with a torch attached, or
combining two unrelated tools without new
functionality.
•Policy Rationale: Promotes only combinations that
create new technical effects or synergistic results.

Clause 3(g)
Omitted Clause (Deleted in 2002 Amendment)
•Historical Context: Originally excluded certain
subject matter, later deemed unnecessary.
•Amendment of 2002: Clause formally removed as
part of patent law modernization.
•Current Relevance: Not applicable today; serves as
a reminder of evolving IP frameworks.

Clause 3(h)
Methods of Agriculture or Horticulture
Exclusion Scope
Prevents patenting of methods
related to agriculture and horticulture
practices.
Examples
Ploughing techniques, irrigation
methods, crop rotation strategies.
Policy Rationale
Protects farmers’ knowledge and
ensures food production practices
remain accessible.
Clause 3(i)
Methods of Treatment for Humans or Animals
Exclusion Scope
Medical, surgical, therapeutic, and
diagnostic methods are not
patentable.
Rationale
Ensures healthcare professionals can
freely treat patients without patent
restrictions.
Examples
Surgical techniques, diagnostic
procedures, veterinary treatments.
Clause 3(j)
Plants, Animals, and Biological Processes (Except Microorganisms)
•Exclusion Scope: Plants, animals, and essentially
biological processes for their production are not
patentable.
•Exception: Microorganisms and microbiological
processes may be patented if novel and inventive.
•Policy Rationale: Protects biodiversity and prevents
monopolization of living organisms.

Clause 3(k)
Mathematical/Business Methods & Software per se
•Exclusion Scope: Mathematical or business
methods and software programs 'per se' are
excluded from patentability.
•Rationale: Abstract ideas and algorithms are not
considered inventions under patent law.
•Practical Note: Software tied to novel hardware or
producing technical effect may still qualify.

Clause 3(l)
Literary, Musical, and Artistic Works
•Exclusion Scope: Artistic, musical, dramatic, or
literary creations are not patentable.
•Correct IP Category: Such works fall under
copyright law, not patent law.
•Policy Rationale: Preserves patents for technical
inventions while safeguarding creative expression
under copyright.

Clause 3(m)
Mental Acts or Methods of Playing Games
•Exclusion Scope: Methods involving purely mental
acts or rules for games are not patentable.
•Rationale: Intellectual skills and recreational
methods are public goods, not inventions.
•Examples: Chess strategies, puzzle-solving
methods, gaming rules.

Clause 3(n)
Presentation of Information
Exclusion Scope
Schemes, rules, or methods for
presentation of information are not
patentable.
Rationale
Such presentations lack technical
contribution and remain non-
inventions.
Examples
Calendars, data charts, teaching
methods, information layouts.
Clause 3(o)
Topography of Integrated Circuits
Exclusion Scope
Designs and layouts of
semiconductor integrated circuits are
not patentable.
Correct IP Category
Such designs are protected under
the Semiconductor Integrated
Circuits Layout-Design Act, 2000.
Policy Rationale
Separates patent law from
semiconductor design rights,
ensuring proper protection regimes.
Clause 3(p)
Traditional Knowledge
Exclusion Scope
Traditional knowledge, including
folklore, indigenous remedies, and
cultural practices, is not patentable.
Rationale
Such knowledge belongs to
communities collectively and must
remain publicly accessible.
Examples
Turmeric’s healing use, neem’s
pesticide properties, Ayurvedic
formulations.
