Copyright law is an essential pillar of intellectual property protection worldwide, and it plays a crucial role in fostering creativity and innovation. One of the fundamental principles of copyright law is the distinction between ideas and expressions. This principle distinguishes between protecting the expression of ideas and the ideas themselves, establishing a delicate balance between fostering creativity and preserving access to the public domain. In India, as in many other countries, the distinction between an idea and its expression is a cornerstone of copyright law. This article intends to provide a comprehensive analysis of the dichotomy between idea and expression within the context of copyright law in India.

Understanding the Idea-Expression Dichotomy

A fundamental principle of copyright law, the idea-expression dichotomy distinguishes between an author’s original expression of an idea and the idea itself. While copyright protects the form or manner in which an idea is expressed, it does not protect the idea or concept itself. This distinction is essential for fostering creativity, encouraging the creation of new works, and ensuring that knowledge and information remain accessible for the public good.

The concept of a detective solving a complex murder mystery, for instance, is not copyrightable. Nonetheless, a particular film script with its own plot twists, characters, and dialogues would be protected.

The Indian Copyright Act, 1957

The Copyright Act of 1957 outlines the distinction between ideas and expressions. Section 13 of the Act defines what can be protected by copyright, emphasising that only original literary, dramatic, musical, and artistic works are eligible for copyright protection. The Act excludes explicitly from copyright protection ideas, procedures, methods of operation, and mathematical concepts.

Case Study: R.G. Anand v. Deluxe Films (1978)

The case of R.G. Anand v. Deluxe Films (1978) is a landmark case in Indian copyright law that clarified the idea-expression dichotomy in the context of copyright protection. This case centred on a dispute regarding the film adaptation of a renowned play.

(A) Background:

The plaintiff in this case, R.G. Anand, was the playwright and author of the popular Hindi play “Hum Hindustani.” The play’s plot centred on communal harmony and unity in India and was set against the backdrop of a city ravaged by violence. The play had been performed numerous times and garnered positive reviews.

The defendant, Deluxe Films, expressed interest in adapting the play into a film. However, Anand and Deluxe Films’ negotiations broke down, resulting in a legal dispute. Anand asserted that “Ghar Ghar Ki Kahani,” a film produced by Deluxe Films, infringed upon his copyright by copying substantial portions of his play.

(B) Key Issues:

The central issue in this case was whether the film “Ghar Ghar Ki Kahani ” had indeed copied the language of Anand’s play to the point where it constitutes copyright infringement.

The plaintiff asserted that the film borrowed heavily from his play, including the central theme of communal harmony, the portrayal of key roles, and numerous dialogues and scenes. He asserted that his creative expression was reproduced without his permission and in violation of the law in the film.

The defendant, on the other hand, defended itself by claiming that while there may be similarities between the play and the film in terms of the larger theme of communal harmony, there was no substantial copying of the specific expression. They argued that the film was an independent work inspired by a prevalent social issue and therefore did not violate Anand’s copyright.

(C) Court’s Decision:

In its decision, the Supreme Court of India was crucial in establishing and emphasising the idea-expression dichotomy within copyright law. 

The court ruled in favour of the defendants and clarified that copyright protection extends to the expression of an idea, but not to the idea itself. It emphasised that ideas, themes, and plots are accessible to all and are not protected by copyright law.

The Role of Originality

For a work to qualify for copyright protection in India, it must meet the criterion of originality. This means that the work must be the result of the author’s independent skill and judgement, and not merely a rehash of previously published material. Originality is an essential aspect of the dichotomy between idea and expression, as it ensures that only truly creative and unique expressions receive copyright protection.

The Importance of the Dichotomy

The idea-expression dichotomy in India’s copyright law is vital for several reasons:

Fostering Creativity: By protecting the expression of ideas rather than the ideas themselves, copyright law fosters innovation and creativity. Authors are encouraged to build upon existing ideas and concepts to create new and unique works.

Preserving Central Themes: Allowing ideas and concepts to remain in the public domain ensures the free flow of information and knowledge for the benefit of society. It prevents monopolisation of fundamental concepts and knowledge.

Legal Certainty: The distinction between ideas and expressions provides legal clarity, allowing creators and the judiciary to distinguish between what is and is not protected by copyright law.


The idea-expression dichotomy is a fundamental principle of India’s copyright law that plays a crucial role in fostering creativity, preserving the public domain, and establishing legal clarity. Through various judicial decisions and legislative provisions, India has upheld this distinction, ensuring that copyright protection is accorded to the original expression of ideas
