What do American Airlines, British Airways, Holiday Inn & Vision Express all have in common?
They are all descriptive names and all have trademarks.
The first rule of trademarks is that the have to be unique, I always say, you can’t trademark ‘London Butcher’ as it would in theory stop other butchers in London from advertising their services.
So, why do those 3 power houses above get to trademark those names, the answer? Acquired Distinctiveness.
What Is Acquired Distinctiveness?
Acquired distinctiveness, also known as secondary meaning, refers to a legal principle where a brand becomes registrable because consumers have come to associate it with a specific business. This applies when a mark was originally too descriptive, generic, or non-distinctive to qualify for protection on its own.
It is often the only option available when a brand name describes a product or feature, but has since taken on new meaning through public use and recognition.
What Kind of Trademarks Might Rely on It?
You may need to rely on acquired distinctiveness if your trademark:
– Describes the goods or services directly (e.g. ‘Fast Plumbing’ or ‘Fresh Bakes’)
– Refers to a place name or region
– Consists of a basic colour, letter, or number
– Involves a shape or design element that is functional or familiar
– Is a commonly used industry phrase or expression
These kinds of trademarks are often seen as too weak to register initially, but if they have been used prominently, consistently, and recognisably, they can sometimes be protected with the right supporting evidence.
Here are some other high profile examples of Wins and Losses involving acquired distinctiveness.
Famous Examples Include:
LOSS- Nestlé’s KitKat Shape: Nestlé tried to register the four-finger shape of its chocolate bar based on acquired distinctiveness. However, the court found that while consumers recognised the shape, they did not necessarily see it as an indicator of trade origin, which is the key legal test.
WIN THEN LOSS- Cadbury’s Purple (Pantone 2685C): Cadbury spent decades associating the colour purple with its milk chocolate packaging. In 2012, the High Court accepted that the colour had acquired distinctiveness and allowed its registration. However, this was later overturned in 2014 by the Court of Appeal, which ruled that the way Cadbury had described the colour was too vague to qualify as a legally registrable sign. This case highlights the difficulty of protecting colour trademarks, even where there is clear consumer recognition.
WIN – Toblerone’s Triangular Shape: A positive example where the distinctive shape of the packaging was recognised as having acquired distinctiveness due to consistent branding and advertising.
How Do You Prove Acquired Distinctiveness?
Proving acquired distinctiveness means showing that the relevant public recognises the mark as your brand, not just as a product description or decorative feature. There is no exact formula, but the UKIPO and EUIPO will look for detailed and persuasive evidence, usually including:
1. Length and consistency of use
2. Geographic scope of use
3. Sales and market share
4. Advertising and promotional efforts
5. Evidence of recognition
6. Examples of the mark in use
In the UK, this is usually compiled into a witness statement with supporting exhibits, prepared either at the time of application or in response to an objection.
Update, 20 May 2026: We have recently taken two clients through examination with highly descriptive trademarks, the kind many people would write off on day one. Both relied on acquired distinctiveness, and the approach was the same for each: build a clear story, then back every part of it with evidence. Think of it as a character reference for the name. Saying customers know you isn’t enough; the file has to show it. For these two cases that meant pulling together sales figures, marketing material, website history and traffic data, evidence of customer reach and brand recognition, and the geographic spread of each business. We then turned that into a structured legal argument for acquired distinctiveness. Each case took close to a year. Nothing was wrong with the system; cases like these simply need depth, detail and patience. This is where many DIY applications struggle. The idea rarely fails. The evidence, structure and strategy behind it usually do.
How Long Does It Take to Build Acquired Distinctiveness?
There is no set timeframe. It depends on the strength of the evidence and the nature of the mark.
– In some cases, three to five years of consistent, prominent use may be enough, especially in niche markets.
– For broader or more descriptive terms, it may take longer and require much more substantial evidence.
– Simply using a brand for 10 years is not enough on its own, the key is not time, but public perception.
When Is It Worth Trying?
Acquired distinctiveness can be the right path when:
– You have used a name or visual element for years, but are facing a rejection due to descriptiveness
– You are the original or leading business in your field, and the public sees your brand as the default
– You want to enforce your rights or prevent competitors from using similar branding
It is especially relevant for brands looking to grow or sell their business, as an unregistered descriptive name may have little value unless protection has been secured.
Final Thought
Acquired distinctiveness is not about how long you have been using your brand. It is about whether your customers recognise it, and whether you can prove it.
If you are facing refusal on the grounds that your mark is too descriptive, or you have built a strong identity without protection, we can help. From preparing witness statements to reviewing historic use and gathering evidence, The Trademark Helpline can guide you through every stage.
We are fortunate in the UK that the cost of a trademark is relatively low. Gaining acquired distinctiveness in the UK can still carry some wait in Europe and may even give you priority in trying to secure that trademark in other countries you trade in overseas.

Questions about this
How can a descriptive name like British Airways be registered as a trademark?
Through acquired distinctiveness. A name that would normally be too descriptive can become registrable once the public has come to associate it with one specific business. That is why names such as American Airlines, British Airways, Holiday Inn and Vision Express hold trademarks. The test is not how long the name has been used, but whether customers recognise it as a brand, and whether you can prove it.
What evidence is needed to prove acquired distinctiveness?
The UKIPO and EUIPO look for detailed, persuasive evidence that the public recognises the mark as your brand. That usually covers the length and consistency of use, its geographic scope, sales and market share, advertising and promotion, evidence of recognition and examples of the mark in use. In the UK it is normally compiled into a witness statement with supporting exhibits.
How long does an acquired distinctiveness case take?
There is no set timeframe. In some cases three to five years of consistent, prominent use may be enough to build acquired distinctiveness, particularly in niche markets, while broader terms need more substantial evidence. The examination itself can also take time: two recent client cases with highly descriptive trademarks each took close to a year, because they needed depth, detail and patience.
What happened with Cadbury’s purple colour trademark?
Cadbury spent decades associating the colour purple, Pantone 2685C, with its milk chocolate packaging. In 2012 the High Court accepted that the colour had acquired distinctiveness and allowed its registration. In 2014 the Court of Appeal overturned that, ruling that the way Cadbury had described the colour was too vague to be a legally registrable sign. It shows how hard colour marks can be to protect.
