Copyright dilution refers to a concept more commonly associated with trademark law than copyright law.

While trademark dilution focuses on the weakening or diminishing of a famous trademark’s strength due to unauthorised use, the concept of dilution isn’t directly applicable to copyrights.

However, for clarity’s sake, we’ll explore both concepts briefly.

Trademark Law Concept

A symbol, word, or phrase legally registered or established through its use as representing a company or product. It ensures consumers can distinguish between products and services of different entities.

Copyright Law

Copyright protects original works of authorship, including literary, dramatic, musical, and certain other intellectual works.

Unlike trademarks, copyrights don’t require distinctiveness, nor are they aimed at preventing confusion among consumers.

Instead, copyright ensures creators retain exclusive rights to reproduce, distribute, perform, and display their work.

Concept of Dilution

Dilution can be primarily split into two categories: Blurring and tarnishment.


It occurs when the uniqueness of a well-known mark is diminished by an unauthorised version.

For instance, if a company uses the ‘INSTAGRAM’ name for a line of shoes, consumers might start associating the globally recognised INSTAGRAM brand with footwear.

This could adversely affect Instagram’s brand perception.


It happens when a well-known trademark is used in a context that’s either inappropriate or derogatory, suggesting views that are at odds with the original brand’s values.

Imagine if the “APPLE” name was used for a pesticide product; this would be a case of trademark dilution through tarnishment.


Beyond these two, the European Union has introduced another form of dilution known as ‘free-riding.’

This happens when an unauthorised entity suggests an affiliation with a famous brand to benefit from its positive image.

Typically, free-riding aims to financially exploit a well-known brand’s established goodwill.

For example, launching a line of eyewear with the ‘NETFLIX’ name might be considered dilution by free-riding, as it piggybacks on Netflix’s strong reputation.

Trademark Dilution

In layman’s terms, trademark dilution happens when someone uses a trademark without permission in a way that weakens or tarnishes the reputation of a well-established trademark.

Interestingly, this often occurs between businesses, well-known companies, or individuals that aren’t even direct competitors.

Can Copyrights be “Diluted”?

Not in the same way trademarks can.

While unauthorised use of copyrighted work can diminish its value or the owner’s ability to profit from it, this isn’t termed “dilution” in legal contexts. Instead, such unauthorised uses would typically be considered infringements.

In conclusion, while actual dilution is a significant concept in trademark law, it doesn’t have a direct parallel to copyright law.

It’s crucial to understand the distinct objectives and protections provided by trademarks and copyrights to navigate intellectual property laws effectively.

Distinctiveness: The Core of Dilution Protection

The foundation for dilution protection is the distinctive quality of a trademark.

A trademark’s strength lies in its distinctiveness – the degree to which it’s recognisable and associated with a specific source or quality in the public’s mind. The more distinctive a reputed mark, the more eligible it is for the protection of trademark dilution.

The Intersection of Copyright Infringement and Trademark Dilution

Where things get particularly interesting is at the junction of copyrights and trademarks.

Consider merchandise like T-shirts or posters featuring copyrighted images. If these items start bearing images similar to a registered, distinctive trademark, it might lead to dilution of that trademark.

While the act of reproducing the copyrighted image might be a copyright violation, the potential dilution of the trademark adds another layer of complexity.


In the intricate landscape of intellectual property, understanding the nuances between trademark infringement and copyright dilution is paramount.

For a trademark owner, the true essence of their identity lies in the distinctive quality of their registered trademark.

Dilution protection serves as a crucial shield to uphold this distinctiveness, especially when the trademark possesses a high degree of distinctiveness.

When an unauthorised entity uses a trademark on products that bears a degree of similarity to a well-known mark, it can jeopardise the uniqueness of the latter.

Particularly, dilution by tarnishment occurs when this unauthorised use degrades the reputation of a distinctive mark.

The famous mark owner, in such scenarios, has the right to file a dilution claim under the dilution protection law, emphasising that even if consumers aren’t necessarily confused, the very essence of their trademark is being diluted.

The basis for dilution protection is not just rooted in the marketplace’s practical realities but is also anchored firmly in the Federal trademark statute of law.


What are the exceptions to dilution of Mark?

Dilution claims won’t apply to:

(a) Fair use of a famous mark, not indicating the source for one’s own products or services. This includes its use in advertising for consumer comparison or commenting on the famous mark or its goods/services.

What is the history of trademark dilution?

The concept of trademark dilution originated in 1927, introduced by Frank I. Schechter in “The Rational Basis of Trademark Protection” in the Harvard Law Review.

Schechter emphasised that trademarks should be protected beyond public deception, preserving their originality and uniqueness. He is often referred to as the ‘father of dilution’ for shaping this doctrine.

Are there real-world examples of marks leading to dilution issues?

Examples of marks leading to dilution issues abound. Consider a hypothetical scenario where a globally recognised tech brand has its logo replicated by a small toy company.

Even if there’s minimal likelihood of confusion – since consumers can differentiate between tech products and toys – the mere copying of the mark might dilute the tech brand’s distinctiveness.

If I’m a trade mark owner, how do I ensure that my mark doesn’t dilute another’s, especially when there’s no intention of copying?

As a trade mark owner, it’s essential to conduct comprehensive market research and trademark searches before finalising a mark.

This ensures that your chosen mark doesn’t bear a high degree of similarity to an existing one, thus minimising the likelihood of dilution or infringement.

Additionally, seeking legal counsel or expertise in trademark law can guide you in avoiding potential pitfalls.

How does the likelihood of confusion between two marks determine if dilution has occurred?

The likelihood of confusion pertains more to traditional trademark infringement, where consumers might confuse one brand for another.

Dilution of trademarks refers to the weakening of a famous mark’s uniqueness and strength, irrespective of the potential for confusion.

However, a high likelihood of confusion might indicate that a mark amounts to a violation, especially if one brand deliberately aims to mimic another.

What form of dilution will fraudulent marks lead to, and how does it differ from legitimate marks?

Fraudulent marks often lead to a form of dilution called “tarnishment”.

This happens when the integrity and reputation of a well-recognised trademark are harmed by its association with unsavory or inappropriate products or services.

On the other hand, legitimate marks aim to maintain the purity and reputation of the brand, ensuring there’s no potential for confusion.

Does the degree of recognition or extent of advertising impact the determination of a trademark’s dilution?

Yes, the degree of recognition plays a significant role.

A trademark that’s widely recognised due to extensive advertising or inherent distinctiveness has a stronger claim against dilution.

For instance, if “apparels for dogs” become highly popular and extensively advertised, another company introducing “breakfast cereals” with a very similar or identical mark might lead to dilution, as the original mark’s distinctiveness gets compromised.
