Striking a Chord: What all brand owners can learn from Fender’s latest IP battle 

Fender’s recent dispute surrounding the shape of its iconic Stratocaster guitar has generated headlines well beyond the music industry. Whilst the legal battle centres on whether Fender can prevent competitors from marketing certain “S-style” guitars, the wider issues will be familiar if you’re considering how best to protect and enforce your own intellectual property rights.

In this article, we’ll look at:

• Why Fender has historically struggled to protect the Stratocaster shape.
• The significance of its recent success in Germany.
• The reputational and commercial risks associated with enforcement campaigns.
• Why the next phase of the dispute may prove more important than the initial case.
• The broader lessons for UK businesses developing an IP enforcement strategy.

What happens when an iconic design becomes an industry standard?

Fender has faced a challenge familiar to many successful businesses: the more successful a product becomes, the harder it can be to maintain exclusivity over key aspects of it.

The Stratocaster shape has been copied and adapted for decades. Fender has previously struggled to secure trade mark protection for the shape, with decision-makers concluding that it had become too commonplace to serve as an indicator of origin. The design is now so widely recognised that it is often viewed as the default silhouette of an electric guitar.

A successful product may eventually influence an entire market. When competitors begin adopting similar features to your products, the question becomes whether your available IP rights still offer meaningful protection.

Is a legal victory always enough?

In late 2025, Fender obtained a significant victory before the Düsseldorf Regional Court.

The proceedings concerned a Chinese seller marketing Stratocaster-style guitars through AliExpress into Germany. The defendant did not participate in the proceedings and Fender obtained a default judgment. The court accepted Fender’s argument that the Stratocaster body shape qualified for copyright protection as a work of applied art.

Whilst significant, the ruling came with an important caveat. As the case was uncontested, arguments concerning functionality, originality and the widespread use of the design were never fully tested.

For rights holders, this illustrates an important enforcement risk. A favourable judgment may strengthen your position, but it does not necessarily guarantee success against a better-resourced opponent willing to challenge the underlying legal issues.

Can an aggressive IP enforcement strategy create commercial risks?

Following the decision, Fender reportedly sent cease and desist letters to a range of manufacturers, distributors and retailers.

From a legal perspective, such action is understandable. Rights holders must police their intellectual property rights and address potential infringement to retain their monopoly rights.

However, enforcement activity increasingly plays out in public. Fender’s campaign attracted criticism from musicians, online commentators and YouTube creators who questioned whether the Stratocaster shape should still be regarded as proprietary after decades of widespread use.

Whether that criticism is justified is not really the point. The more important lesson is that your enforcement activity may be judged not only by a court, but also by customers, distributors and industry stakeholders.

Before commencing enforcement action, you should therefore consider both the legal and commercial implications. A strategy that is legally sound may still create reputational damage if it is perceived as disproportionate.

Why the next stage of the dispute may matter more than the initial claim

The most significant development may not be Fender’s original success but the response it generated.

Thomann, one of Europe’s largest music retailers, has challenged Fender’s position and is seeking a declaration of non-infringement before the same Düsseldorf court that issued the original decision. Fender has since responded with infringement proceedings of its own.

Unlike the original defendant, Thomann has both the resources and motivation to contest the issues fully. As a result, legal arguments absent from the original proceedings are likely to receive detailed scrutiny.

For your business, this demonstrates the importance of continually reviewing enforcement strategies as disputes evolve. Success against an unrepresented or non-participating defendant does not predict the outcome of litigation against a well-resourced commercial opponent.

IP enforcement strategy: what lessons does this hold for UK businesses?

Whilst the German decision is attracting attention, the wider lessons for UK businesses are arguably more important than the dispute itself.

First, it highlights the importance of identifying the right intellectual property protection at an early stage. Copyright, registered designs, unregistered design rights and trade marks each serve different purposes and should be considered as part of a wider protection strategy.

Secondly, it demonstrates the risks associated with relying heavily on an uncontested judgment. Such decisions can be valuable enforcement tools but may not represent the final answer where future defendants actively challenge the underlying issues.

The dispute also touches on an area of law that continues to develop in the UK. Following Cofemel, courts have shown an increased willingness to recognise copyright protection in works of applied art where sufficient originality exists. At the same time, decisions such as Brompton Bicycle emphasise that copyright should not extend to features dictated purely by technical or functional considerations.

More recent UK authorities, including WaterRower (UK) Ltd v Liking Ltd and THJ Systems Ltd v Sheridan, demonstrate an ongoing judicial focus on maintaining the distinction between copyright and design protection.

If a similar dispute arose in the UK, a court would focus on originality, functionality and the relationship between copyright and design law.

IP enforcement strategy: how we can support you

The Fender dispute serves as a reminder that intellectual property enforcement is rarely just a legal exercise.

When considering an enforcement strategy, you should balance the strength of your rights against litigation risk, commercial relationships, public perception and long-term business objectives.

Whether you’re protecting a valuable product design, developing an enforcement programme, responding to allegations of infringement or reviewing your IP portfolio, obtaining advice early can help ensure that legal objectives remain aligned with wider commercial goals.
