Doctrine of Merger in Copyright Law

The doctrine of merger is a significant principle in copyright law that addresses the intersection of ideas and their expressions. It establishes that when an idea and its expression are so closely intertwined that they cannot be separated, the expression is not eligible for copyright protection. This doctrine seeks to maintain a balance between protecting original expressions and preserving the free flow of ideas in the public domain, which is a foundational principle of copyright law.

Fundamental Principles of Copyright Law

Copyright law primarily seeks to protect original expressions of ideas, not the ideas themselves. This principle is encapsulated in the Idea-Expression Dichotomy, which distinguishes between:

• Protected: The unique, original manner in which an idea is expressed, such as the plot of a novel, the choreography of a dance, or the arrangement of a song.
• Unprotected: Facts, ideas, concepts, and systems.

Section 13 of the Indian Copyright Act, 1957, and similar provisions in other jurisdictions like the United States Copyright Act, specify that only original works that are fixed in a tangible medium are subject to copyright protection. These include literary, artistic, dramatic, and musical works. However, complications arise when an idea and its expression are so closely linked that separating them becomes impossible. This is where the doctrine of merger comes into play.

What Is the Doctrine of Merger?

The doctrine of merger applies in situations where:

1. An idea and its expression are indistinguishable.
2. There is only one or a very limited number of ways to express the idea.
3. Granting copyright protection to such an expression would effectively monopolise the idea itself, contrary to the objectives of copyright law.

The doctrine ensures that copyright law does not inadvertently hinder creativity or limit access to ideas by protecting expressions that are inseparable from their underlying ideas. If an expression is deemed to have merged with its idea, it cannot be copyrighted.

Legal Basis and Applications of the Doctrine of Merger

Preventing Monopolisation of Ideas

The primary purpose of copyright law is to encourage creativity and innovation. Allowing copyright protection for an expression that merges with its idea would grant a monopoly over that idea. This would stifle creativity by preventing others from developing or expressing similar ideas in different ways.

Ensuring Access to Fundamental Concepts

Certain fields, such as mathematics, science, and functional designs, rely heavily on universal principles and ideas. The doctrine of merger ensures that such fundamental concepts remain accessible to all, fostering growth in these fields.

Aligning with Public Policy Goals

By denying copyright protection in cases of merger, courts uphold the public policy goal of promoting the free exchange of ideas while still protecting genuinely original expressions.

Landmark Cases on Doctrine of Merger

The doctrine of merger has been discussed extensively in various landmark cases worldwide, which have shaped its understanding and application.

Herbert Rosenthal Jewelry Corporation v. Kalpakian (US)

In this case, the plaintiffs sought to prevent the defendants from manufacturing bee-shaped jewel pins, claiming copyright infringement. The court ruled that the design of the bee-shaped pin was an idea that could only be expressed in a limited number of ways. Consequently, copyright protection was denied to prevent monopolising the idea of a bee-shaped pin. This case is a classic example of the doctrine of merger being used to safeguard creative freedom.

Affiliated Hospital Products, Inc. v. Merdel Game Mfg. Co. (US)

This case involved game manuals where the rules of the games were integral to their expression. The court applied the doctrine of merger, ruling that the expression of the game rules was inseparable from the idea of the rules themselves. Granting copyright protection would effectively create a monopoly on the rules, which the court deemed contrary to the principles of copyright law.

Chancellor Masters of Oxford v. Narendra Publishing House (India)

The Indian Supreme Court in Chancellor Masters of Oxford v. Narendra Publishing House dealt with the copyrightability of mathematical questions. It held that such questions are expressions of natural laws and can only be represented in a limited number of ways. Extending copyright protection to these questions would hinder access to the ideas they represent. The court applied the doctrine of merger to deny copyright protection, ensuring the free dissemination of knowledge.

Mattel, Inc. & Ors. v. Jayant Agarwalla & Ors. (Delhi High Court, India)

In Mattel, Inc. & Ors. v. Jayant Agarwalla & Ors. , the Delhi High Court provided a detailed explanation of the doctrine of merger. It stated that when an idea and its expression are inextricably connected, copyright protection cannot be granted. Protecting such expressions would effectively grant a monopoly over the underlying idea, which is against the objective of copyright law.

Joshua Et-Hokin v. Skyy Spirits Inc. (US)

This case involved photographs of Skyy Spirits’ recognisable blue bottle. The court ruled that the limited ways to photograph the bottle made the expression inseparable from the idea. Applying the doctrine of merger, the court denied copyright protection, ensuring that the idea remained in the public domain.

Implications of the Doctrine of Merger

• Promoting Creativity: By ensuring that ideas remain freely accessible, the doctrine fosters a thriving creative ecosystem. It allows multiple creators to build on shared ideas, leading to a diverse range of expressions.
• Encouraging Innovation: Fields such as technology, software development, and game design benefit from the doctrine, as it prevents monopolisation of functional designs and operational concepts.
• Preventing Abuse of Copyright: The doctrine acts as a safeguard against attempts to misuse copyright law to claim exclusive rights over ideas, concepts, or systems.
• Balancing Public and Private Interests: While copyright law rewards creators for their original expressions, the doctrine ensures that the public’s interest in accessing ideas and knowledge is not compromised.

Conclusion

The doctrine of merger plays a pivotal role in copyright law by maintaining the balance between protecting original expressions and ensuring the free flow of ideas. It prevents monopolisation, encourages creativity, and aligns with the public policy goals of copyright law. However, its application requires careful judicial interpretation to avoid undermining the rights of creators while preserving the public domain.

Through landmark cases and evolving jurisprudence, the doctrine continues to shape copyright law, ensuring that it serves both private creators and the broader public interest. As creativity and innovation evolve in the digital age, the doctrine of merger will remain a critical tool for navigating the complex interplay between ideas and their expressions.
