Non-Conventional Trademarks in India: Can You Trademark a Sound, Shape, Colour, or Smell?

Non-Conventional Trademarks in India: Can You Trademark a Sound, Shape, Colour, or Smell?

Close your eyes and think of a brand. Chances are, you did not just picture a logo — you probably heard a jingle, imagined a specific colour, or pictured the exact shape of a bottle. That instant recognition, without a single word being read, is the power of branding that goes beyond just names and logos.

Most Indian business owners know they can trademark a brand name or a logo. But very few realise that Indian law also allows you to protect a distinctive sound, a unique shape, a signature colour combination, and — in rare, difficult cases — even a smell. These are called non-conventional trademarks, and if your brand has built genuine recognition around one of these elements, leaving it unprotected is like leaving your front door open. Let us understand exactly how this works.

What Are Non-Conventional Trademarks

A trademark, at its core, is any sign capable of distinguishing the goods or services of one business from another. Traditionally, that meant word marks (brand names), logos, and taglines. But the Trade Marks Act, 1999 in India defines a "mark" broadly enough to include a lot more than just words and images — it can include a device, brand, heading, label, ticket, name, signature, word, letter, numeral, shape of goods, packaging, or combination of colours.

This broader definition opened the door for what are commonly called non-conventional or non-traditional trademarks — trademarks that do not rely on a word or a standard visual logo, but instead on:

• Sound marks — a distinctive audio signature, like a jingle or tune associated with a brand.
• Shape marks — the distinctive three-dimensional shape of a product or its packaging.
• Colour marks — a specific colour or combination of colours consistently associated with a brand.
• Smell marks — a distinctive scent associated with a product (extremely rare and difficult to register in practice).

These are not new legal categories invented for marketing gimmicks — they exist because consumers genuinely identify brands through senses other than reading a name. If your business has built that kind of recognition, Indian trademark law gives you a route to protect it, subject to certain strict conditions.

Why Non-Conventional Trademarks Matter for Indian Brands

Here is the practical reality: word and logo trademarks are easy to copy-paste around. But a distinctive sound, shape, or colour scheme that consumers instantly associate with your brand is much harder for a copycat to imitate convincingly — and equally, much more powerful when you can stop others from using something confusingly similar.

Think about why this matters for growing Indian businesses:

• D2C and FMCG brands often build strong shape or packaging recognition — a distinctively shaped bottle, jar, or container that consumers recognise on a crowded shelf without reading the label.
• Media, telecom, and app-based businesses frequently use short sound signatures (notification tones, startup jingles, ringtones) that become deeply associated with the brand.
• Retail and consumer brands sometimes build recognition around a signature colour combination used consistently across packaging, signage, and marketing.

If you have invested years of marketing spend building this kind of recognition and a competitor starts using a deceptively similar sound, shape, or colour scheme, a conventional word-mark registration alone will not help you stop them. You need the non-conventional element itself registered — or at minimum, strong documented evidence of its distinctiveness — to have real legal recourse.

Key Concepts: How Each Type of Non-Conventional Mark Works

Sound marks

A sound mark is typically represented through a graphical notation (such as musical notes on a stave) along with an accompanying sound clip submitted in the prescribed audio format. The applicant must show the sound is capable of distinguishing their goods or services and is not merely a generic or commonly used sound in that industry (a simple, everyday ringtone-type beep, for instance, would struggle to qualify).

Shape marks (three-dimensional marks)

Shape marks protect the distinctive three-dimensional form of a product or its packaging. However, Indian law places specific restrictions here: a shape cannot be registered as a trademark if it results exclusively from the nature of the goods themselves, if it is necessary to obtain a technical result, or if it gives substantial value to the goods. This means purely functional shapes are excluded — the shape must be an arbitrary, distinctive design choice, not something dictated by function or manufacturing necessity. This is often better protected initially (or additionally) through a design registration, though a shape can also qualify as a trademark if it functions as a genuine source identifier over time.

Colour marks

A single colour, used in isolation, is very difficult to register as a trademark in India because colour is generally not considered inherently distinctive — competitors need reasonable freedom to use colours too. A combination of colours, however, applied in a specific, consistent manner is more commonly accepted, provided the applicant can demonstrate the combination has become distinctive of their brand through extensive and consistent use (this is often referred to as acquired distinctiveness or "secondary meaning").

Smell marks

Smell marks are the rarest and most legally challenging category, globally and in India. The core difficulty is the requirement of graphical representation — a scent must be represented in a way that is clear, precise, and can be understood by the public and competent authorities examining the application. Since there is no universally accepted, objective way to graphically depict a smell (unlike a sound's musical notation), very few smell marks have ever been successfully registered anywhere in the world, and Indian applicants should treat this category as exceptionally difficult, requiring specialist advice and often relying on alternative protection strategies like passing off or contractual measures instead.

What You Need to Protect a Non-Conventional Mark

1. Clear graphical or notational representation of the mark — musical notation and an audio clip for sound marks, professional line drawings from multiple angles for shape marks, and precise colour codes (such as Pantone references) for colour combination marks.
2. Evidence of distinctiveness, especially for shape and colour marks, since these categories usually require proof of "acquired distinctiveness" through consistent, extensive commercial use — think sales figures, advertising spend, years of continuous use, and consumer surveys if available.
3. A description explaining why the mark is not functional or generic — critical for shape marks, to show the design is not dictated purely by function or a technical necessity.
4. Classification under the correct class(es) of goods or services as per the applicable classification system used in Indian trademark filings.
5. A trademark search to check no identical or deceptively similar non-conventional mark is already registered or pending in the same class.
6. Consistent usage records — invoices, packaging samples, advertisements, and media clips showing the mark has been used exactly as claimed, over time, without material variation.

Because non-conventional marks face a much higher bar of scrutiny at the examination stage compared to standard word or logo marks, the application, supporting evidence, and representation must be prepared meticulously. Weak documentation is the single biggest reason these applications get objected to or rejected.

Cost & Fees 2026

Government filing fees for trademark applications in India vary depending on the applicant category (individual, startup, MSME, or company) and whether the mark is filed in one class or multiple classes. Non-conventional marks are filed using the same fee structure as standard trademark applications, but typically require significantly higher professional fees because of:

• The specialised drafting needed for graphical representation (especially sound and shape marks).
• The additional evidence and documentation required to establish distinctiveness.
• The higher likelihood of examination objections requiring detailed written responses and possibly a hearing.

Because government fee schedules are revised periodically and professional fees vary by complexity, always verify the current rate before filing and insist on a written, itemised quote covering both government and professional charges.

Timeline & Validity

Non-conventional trademark applications generally take longer to examine than standard word or logo marks, since examiners scrutinise the graphical representation and distinctiveness evidence more closely. It is common for such applications to face at least one examination objection, particularly around distinctiveness or functionality, which then requires a written response and sometimes a hearing before the Registrar. Depending on objections and oppositions (if any third party challenges the application after it is advertised), the overall registration process can take anywhere from about one to several years.

Once registered, a trademark in India — conventional or non-conventional — is valid for 10 years from the date of registration, and can be renewed indefinitely for further 10-year periods as long as renewal formalities and fees are completed on time. Unlike a patent, a trademark can theoretically last forever if it continues to be used and renewed.

Non-Conventional vs Conventional Trademarks: Key Distinctions

• Representation requirement: Conventional marks (words, logos) are represented simply as text or images; non-conventional marks require specialised representation such as musical notation with audio clips, multi-angle drawings, or precise colour codes.
• Distinctiveness bar: Word and logo marks can often register based on inherent distinctiveness; shape and colour marks usually must prove acquired distinctiveness through extensive prior use.
• Examination scrutiny: Non-conventional applications typically face closer scrutiny and higher objection rates compared to standard marks.
• Functionality exclusion: Shape marks specifically cannot be registered if the shape is functional, technical, or gives substantial value to the goods — a restriction that does not apply the same way to word or logo marks.
• Global registrability: Sound and colour combination marks are moderately achievable with the right evidence; smell marks remain almost impossible to register anywhere in the world, including India, due to the graphical representation requirement.
• Overlap with other IP rights: Shape marks often overlap with design registration under the Designs Act; brands sometimes pursue both to cover different angles of protection.

Common Mistakes Brand Owners Make

• Assuming any color or sound automatically qualifies. Distinctiveness must usually be proven through years of consistent, exclusive use — a mark used for just a few months is unlikely to succeed.
• Filing a shape mark for a purely functional design. If the shape exists mainly because of how the product works or is manufactured, the application will likely be refused.
• Using the sound or colour inconsistently across products or regions. Inconsistent use weakens the very distinctiveness argument the application depends on.
• Skipping a proper search before filing. Failing to check existing registrations in the same class often results in office objections or later opposition from prior rights holders.
• Providing weak or vague graphical representation. A blurry drawing, an incomplete audio file, or an imprecise colour reference is one of the most common reasons for objections in non-conventional filings.
• Not maintaining evidence of use over time. Businesses often fail to systematically preserve invoices, ad spends, and packaging archives — exactly the evidence needed later to prove acquired distinctiveness.
• Trying the smell mark route without expert guidance. Given how rarely smell marks succeed, pursuing this without a clear alternative strategy (like relying on passing-off protection or trade secret style confidentiality) can waste significant time and money.

FAQ

Can I trademark a single colour in India?

It is very difficult. A single colour used in isolation is generally not considered inherently distinctive, since competitors need reasonable freedom to use basic colours. A specific combination of colours, consistently used and proven to be distinctive through extensive use, has a much better chance of registration.

What is needed to register a sound as a trademark?

You typically need a graphical representation such as musical notation, along with an audio clip of the sound in the prescribed format, plus evidence that the sound is distinctive and not a generic or commonly used sound in your industry.

Can I trademark the shape of my product's bottle or packaging?

Possibly, but only if the shape is not dictated purely by function, technical necessity, or if it does not give substantial value to the goods on its own. You will also usually need to show the shape has become distinctive of your brand through consistent use. Many brands also protect shape through design registration as an additional or alternative layer of protection.

Is it possible to register a smell as a trademark in India?

In theory the law does not expressly forbid it, but in practice it is extremely difficult due to the requirement of clear graphical representation, which is very hard to achieve for a scent. Very few, if any, smell marks have been successfully registered in India or globally.

How long does a non-conventional trademark registration last?

Once registered, it is valid for 10 years from the registration date and can be renewed indefinitely for further 10-year terms, provided renewal fees and formalities are completed on time.

Do non-conventional trademarks cost more than regular trademarks?

Government fees generally follow the same structure as standard trademark filings, but professional fees are usually higher due to the specialised documentation, evidence gathering, and higher likelihood of objections involved in non-conventional applications.

What happens if my non-conventional trademark application gets objected to?

This is common for non-conventional marks. You will typically need to file a detailed written response addressing the examiner's objections, often supported by evidence of distinctiveness and use, and in some cases attend a hearing before the Registrar.

Can a competitor use a similar sound or colour if I have not registered it?

If you have not registered the mark, your options are more limited, though you may still have some recourse under passing-off principles if you can show strong, established consumer association with the unregistered mark. Registration provides much stronger, clearer statutory protection and should not be delayed once a mark shows real brand recognition.
