In the UK it is generally lawful to sell a fragrance inspired by another, because a smell itself is very difficult to protect by copyright and is rarely patented. What is unlawful is using someone else's trade mark, copying their packaging, or presenting your product as theirs. Counterfeits are illegal; inspired-by fragrances sold under their own brand usually are not.
A note before anything else. This article is general information about how UK law works in this area, written for shoppers rather than lawyers. It is not legal advice, it cannot account for the facts of any particular product or dispute, and anyone facing a real question about a specific fragrance or business should take advice from a qualified solicitor.
| The question | The short answer |
|---|---|
| Can a smell be copyrighted in the UK? | Almost certainly not, on current law |
| Can a formula be patented? | In principle yes, in practice almost never used |
| Is the brand name protected? | Yes, by registered trade mark |
| Is the bottle protected? | Often, by registered design or 3D trade mark |
| Is "smells like Aventus" marketing safe? | No — this is the riskiest area of all |
| Are counterfeits illegal? | Yes, including criminal offences for sellers |
Three separate laws, three separate questions
Most confusion here comes from treating "is this legal" as one question. It is three, and they have different answers.
The first is intellectual property in the smell — can anyone own the composition itself? The second is intellectual property in the branding — the name, the logo, the bottle shape, the box. The third is the common law of passing off, which asks whether the public is being misled about who made the product. A fragrance can be entirely clear on the first and still be unlawful on the second or third.
Copyright, and why a scent is difficult to own
UK copyright is set out in the Copyright, Designs and Patents Act 1988, and it works through a defined list of categories of protected work: literary, dramatic, musical and artistic works, sound recordings, films, broadcasts and typographical arrangements. A smell does not naturally fit any of them.
Courts elsewhere have disagreed with each other on this. The Dutch Supreme Court once accepted that a perfume could attract copyright, while the French Cour de cassation refused. The European position hardened in 2018 in a case about the taste of a cheese, where the Court of Justice held that a taste could not be a protected work because it cannot be identified with sufficient precision and objectivity. The same reasoning is generally understood to apply to smells. Judgments of that court from before 2021 remain influential in the UK, although UK courts now have greater freedom to depart from them.
Patents are theoretically available for a genuinely novel composition, but the industry rarely uses them. A patent requires you to publish the formula, and protection expires. Perfume houses would overwhelmingly rather keep the formula a trade secret and rely on brand strength instead. So the practical position is that the smell itself is largely unprotected, which is precisely why a whole category of inspired-by fragrances exists.
Trade marks protect the name, not the liquid
Under the Trade Marks Act 1994, registered marks cover brand names, logos and, where registered, distinctive packaging and bottle shapes. Using a registered mark on your own goods without permission is infringement, and there is no "but everyone knows it isn't really theirs" defence.
The area that catches sellers out is comparison marketing. The leading authority is the L'Oréal v Bellure litigation, which reached the Court of Justice in 2009 and concerned smell-alike perfumes sold with comparison lists naming the originals. The court held that using a well-known mark in that way could amount to taking unfair advantage of its reputation, even where nobody was actually confused about who made the product, and that the comparative advertising defence was not available where goods are presented as imitations. The English Court of Appeal applied that ruling in 2010, with the judge making it fairly clear he disliked the outcome.
The practical consequence for UK shoppers is visible on every fragrance site: sellers describe a scent's character rather than printing "this is X". That is not coyness. It is the law.
Passing off, the rule that catches lookalikes
Passing off is a common law action rather than a statute, and it does not require a registered trade mark. The classic three-part test asks whether the claimant has goodwill in the get-up of its product, whether the defendant has made a misrepresentation likely to deceive the public, and whether damage results.
This is what catches products that avoid using the actual brand name but copy the bottle, the colour scheme, the typography and the general look closely enough that a shopper in a hurry might be fooled. A fragrance can therefore infringe nothing on paper and still be unlawful because of how it is presented.
Legal inspired-by against illegal counterfeit
| Feature | Inspired-by fragrance | Counterfeit |
|---|---|---|
| Brand on the bottle | Its own registered name | Someone else's name, without permission |
| Claim made to buyer | A fragrance in its own right | Claims to be the original product |
| Packaging | Its own design | Copies the original's get-up |
| Sold openly by UK retailers | Yes | No — grey market and social selling |
| Safety regulation | Subject to UK cosmetics rules | Unregulated, contents unknown |
| Legal position | Generally lawful | Unlawful, including criminal offences for sellers |
Counterfeiting is not a grey area. Section 92 of the Trade Marks Act 1994 creates criminal offences for the unauthorised use of a trade mark in relation to goods, Trading Standards enforce it, and Border Force can seize counterfeit goods entering the country. Separately, selling fake goods to consumers engages the Consumer Protection from Unfair Trading Regulations 2008. Buyers are not usually the target of enforcement, but they have no consumer recourse, no safety assurance and no way of knowing what is in the bottle.
Where a house like Armaf sits in this
Armaf is a registered brand produced by Sterling Parfums in the United Arab Emirates. Its bottles carry its own name, its own bottle designs and its own product names, and it is stocked openly by mainstream UK retailers. Club de Nuit Intense Man is frequently discussed alongside a famous French fragrance, but it is sold as Club de Nuit Intense Man, not as anything else. The same is true of Tres Nuit Man and Club de Nuit Woman.
That is the entire distinction. A counterfeit lies about what it is. An inspired-by fragrance from a legitimate house takes an idea the law does not protect and sells it under its own name. You may think the second is uninspired — that is a fair criticism and plenty of people make it — but it is a different objection from an illegal one.
It is also worth being honest about the weaker side of the argument. The originators of these compositions invested in the development and the marketing that made them desirable, and inspired-by houses benefit from that work without contributing to it. The law tolerates this. Whether it should is a reasonable thing to disagree about, and nothing above is an argument that the current position is morally settled. If you want to see the scale of the category, the Armaf collection alone runs to hundreds of variations.
When this matters to you, and when it doesn't
This is worth thinking about if:
- You are buying from a marketplace listing or social media seller offering a designer name at an implausible price.
- You sell fragrance and are writing product descriptions or comparison content.
- You are considering a fragrance whose packaging looks unusually close to a famous original.
- You care about supporting the houses that originate compositions rather than follow them.
It matters far less if:
- You are buying a branded fragrance from an established UK retailer under its own name.
- You already accept that most modern fragrance borrows heavily and are choosing on smell alone.
- The bottle makes no claim to be anything other than what it is.
Again, none of the above is legal advice. If a specific product or a business decision turns on it, speak to a solicitor who works in intellectual property.
Frequently asked questions
Are perfume dupes illegal in the UK?
Generally no, provided they are sold under their own brand name and packaging. The smell itself is very hard to protect in UK law, so producing a fragrance inspired by another is usually lawful. What is unlawful is using another company's trade mark, imitating its packaging, or presenting the product as the original.
What is the difference between a dupe and a fake?
A dupe or inspired-by fragrance is a legitimate product sold under its own name that happens to smell similar to something else. A fake is a counterfeit: it carries another brand's name and packaging without permission and lies about what it is. The first is generally legal, the second is not.
Can a perfume be copyrighted?
Almost certainly not in the UK. Copyright law protects a defined list of categories of work and a smell does not fit them. European case law on the taste of a food product has reinforced this reasoning, on the basis that a scent or taste cannot be identified with sufficient precision and objectivity to be a protected work.
Why do retailers avoid saying a fragrance smells like a designer brand?
Because of trade mark law. Litigation involving smell-alike perfumes established that using a well-known mark in a comparison list can amount to taking unfair advantage of its reputation, even without consumer confusion. Retailers therefore describe a scent's character rather than naming the fragrance it resembles.
Is it illegal to buy a counterfeit perfume for personal use?
Enforcement in the UK is aimed at sellers and importers rather than individual buyers, but counterfeit goods can be seized by Border Force and you have no consumer protection if something goes wrong. The bigger practical risk is safety, since the contents of a counterfeit bottle are entirely unknown.
Is Armaf a legal brand in the UK?
Yes. Armaf is a registered brand produced by Sterling Parfums, sells under its own product names and bottle designs, and is stocked by mainstream UK retailers. Its fragrances are often compared to more expensive originals, but they are marketed as Armaf products rather than as anyone else's.
