That is no coincidence. That is industrial property applied to business strategy.
The Coca-Cola bottle is an iconic example of what is legally termed a three-dimensional trademark. A shape that, on its own, is worth billions.
What is a three-dimensional trademark?
When we think of trademarks, we tend to limit ourselves to names, logos or typefaces. However, the law allows the shape of a product or its packaging to be protected under one essential condition:
That the consumer automatically associates the shape with a specific company.
At this point, the design ceases to be merely aesthetic and becomes a legal identity.
The Coca-Cola case: A monopoly born of a challenge
In 1915, Coca-Cola launched a challenge to create its famous Contour Bottle. The objective was as ambitious as it was brilliant: they wanted a container that could be recognised even in the dark, by touch, or if the bottle were to shatter.
They succeeded. The design – inspired by the contour of a cocoa pod – became the multinational’s most closely guarded asset, alongside its recipe. By registering it as a three-dimensional trademark, they obtained a perpetual right (provided it is renewed) to prevent any competitor from using a similar design that might confuse the public.
Expert level: Why is it so difficult to register a shape?
Registering packaging is, quite literally, the ‘advanced level’ of industrial property. It is not enough for the design to be ‘attractive’. The Registries, particularly the doctrine of the EUIPO (European Union Intellectual Property Office) based in Alicant, and the Courts require proof that:
- It is not a functional shape: If the shape is necessary for the product to function (e.g. the shape of a screw), it cannot be a trade mark.
- It is not generic: You cannot register the standard shape of a water or soft drink bottle.
- It has distinctive character: The public must have come to recognise that “that shape” signifies the origin and quality of “that brand”.
Icons that need no introduction
Although Coca-Cola is the benchmark, other brands have realised that the silhouette is the best form of marketing:
- Toblerone: Its triangular shape (inspired by the Alps) is its strongest legal defence.
- Chanel No. 5: A bottle whose shape is as famous as its scent.
- Pringles: The tubular tube that broke the rules of the snack industry.
- Absolut Vodka: A silhouette so powerful that it allowed the label to be omitted from its advertising campaigns.
In fact, the design of the frosted cava bottles has long since reached the Spanish courts.
The strategic mistake: ‘Off-the-shelf’ packaging
Many companies and entrepreneurs devote considerable effort and investment to logos and websites, but neglect their packaging. Using generic, off-the-shelf packaging carries two serious risks in 2026:
- Invisibility: You look exactly the same as your competitors.
- Vulnerability: If a competitor uses your exact packaging tomorrow and takes away your sales, you won’t have sufficient legal tools to stop them.
Your design is your defence. If your product has a shape that makes it unique, failing to register it as a Trade Mark or Design leaves the door open for others to take advantage of your market position.
Checklist: Is your design registrable?
Before taking the legal step, check whether your packaging meets these requirements:
- Distinctiveness: Does it clearly stand out from what is already on the market?
- Non-functionality: Does the shape offer something more than mere technical utility?
- Recognition: Could your customers recognise your brand just by its silhouette?
Conclusion: Aesthetics is strategy
The Coca-Cola bottle teaches us that industrial property is not just about paperwork and formalities; it is about perception, and the resulting positioning and reputation in the market.
These considerations apply to the packaging, and frequently to the labelling and communication strategy.
If you can make the design and presentation of your product speak for itself, you will have created an asset that your competitors cannot replicate. Because in today’s market, it is what cannot be copied that generates real value.
Is your product recognisable in the dark? If the answer is, yes, make sure that the legal registration is as robust as your design.
