Ask almost anyone to picture Adidas, and the image is instant: three parallel stripes running down a shoe or tracksuit. The association feels automatic, even inevitable. From a consumer perspective, the stripes are Adidas.
Yet, time and again, courts across the world have told Adidas the same thing: no, you cannot own them.
This disconnect between public perception and legal reality sits at the heart of Adidas’ decades-long trademark battle and reveals something important about how trademark law, competition, and brand psychology collide.
The Most Recent Case: Adidas vs Forever 21
One of the most talked-about disputes in recent years involving Adidas’ three-stripe mark is Adidas’ lawsuit against Forever 21 over alleged infringement of its trademarked stripe design.
While it may seem confusing at first glance towards the party involved, as Forever 21 is a fashion brand that is known for producing clothing items at a lower price, whereas Adidas is an internationally famous brand established in footwear and clothing with a higher selling point. Both brands represent different sectors and target audiences, so where is the case?
Adidas claimed with the US Lanham Act that Forever 21 was selling apparel and footwear featuring stripe patterns that were “confusingly similar” to its famous three-stripe mark, to the point of being counterfeit products.
Adidas argued that its stripes have been built up over decades of brand investment and are associated with millions in sales and global recognition, and that Forever 21’s use of similar stripes could mislead consumers into thinking the products were Adidas-authorised.
In response, Forever 21 filed its own complaint seeking a declaratory judgment that its use of stripes did not infringe Adidas’ trademarks and was not in breach of earlier agreements. Forever 21 countered that the stripes were merely decorative and do not function as a trademark indicating the source of the goods
Other Cases
Europe – EUIPO & General Court
In a long-running battle with Shoe Branding Europe, Adidas attempted to register a very broad three-stripe trademark in the EU, covering stripes in any direction and on any clothing or footwear. European trademark authorities, and ultimately the General Court of the European Union, held that Adidas failed to prove that this broad description had acquired distinctiveness across the entire EU, meaning consumers didn’t universally associate all stripe combinations with Adidas.
This was a significant setback because it showed that even a famous brand like Adidas can fail when its description is too general and not closely tied to specific placements and styles.
Thom Browne
In a notable “stripe vs. stripe” case, Adidas sued luxury fashion label Thom Browne over a four-bar stripe design. However, a U.S. jury found that Browne’s four-stripe look did not infringe Adidas’s three-stripe trademark, with the court essentially signalling that not all stripes are Adidas’s stripes even if the original brand is well known.
This reinforces a key theme: Adidas’ mark may be famous, but fame alone doesn’t automatically make every stripe design infringing under US law.
Steve Madden
In 2025, Steve Madden publicly challenged Adidas’ aggressive trademark behaviour, arguing that Adidas should not be able to claim monopoly rights over all striped footwear, a case reflecting growing industry pushback to broad claims on simple graphical elements
Why Trademark Keep Saying No
At its core, trademark law exists to achieve two objectives:
- protect consumers from confusion
- preserve fair competition
It is not designed to reward creativity, investment, or marketing success in the abstract.
This is why courts treat simple and generic designs, such as stripes, dots, or lines, with particular caution. These elements are visually common, easy to reproduce, and widely used across the fashion industry. Granting exclusive rights over such basic features would risk removing essential design tools from competitors.
Adidas’ central legal difficulty lies in overbreadth. While the company has undeniably used three stripes extensively, its use has been inconsistent in form, orientation, spacing, and presentation. Trademark law requires a mark to be clear, precise, and stable. A concept as general as “three stripes” fails to meet this standard.
Crucially, courts have repeatedly emphasised that acquired distinctiveness must attach to the exact sign applied for, not to a general brand aesthetic or design language. The fact that consumers associate stripes with Adidas does not automatically mean that stripes function as a trademark in every context. Trademark law does not protect mental shortcuts. It protects legal signals of origin. The law asks not “What do consumers associate?” but “What does the mark objectively communicate in trade?” In simple terms, association is not ownership.
Allowing Adidas to claim exclusive rights over “three stripes in any form” would effectively grant a monopoly over a basic visual feature of sportswear, something trademark law is fundamentally unwilling to do.
Enforcement Without Ownership
Interestingly, Adidas has not been powerless. It has successfully enforced its rights in many passing off and infringement actions where competitors’ designs came too close to its established look.
This highlights a key distinction:
- Adidas can stop confusingly similar uses
- But it cannot claim exclusive ownership of stripes as a concept
This selective success fuels public confusion. Consumers see Adidas prevail in enforcement actions and naturally assume that the company “owns” stripes outright. In reality, registration law continues to resist such claims, prioritising clarity, competition, and the availability of basic design elements to the wider fashion industry.
