Fender Is Trying to Own the Shape of Rock Guitar. It Won't Work.

In December 2025, Fender won a copyright ruling in the Regional Court of Düsseldorf, Germany. The case was against Yiwu Philharmonic Musical Instruments Co., a Chinese manufacturer selling Stratocaster-shaped guitars through AliExpress. The ruling established the Stratocaster body as a "copyrighted work of applied art" under German and EU law. It was a default judgment — Yiwu Philharmonic did not appear in court. Fender won because the other side did not show up.

By May 2026, Fender's law firm Bird & Bird had sent cease-and-desist letters to multiple guitar companies, including LsL Instruments, a small family-run boutique builder in California. The letters demanded an immediate stop to manufacturing and marketing of S-style guitars, recall of distributed stock, destruction of existing inventory, handover of sales data, and compensation for legal fees. LsL launched a GoFundMe to cover legal costs and said the demands could threaten the company's survival.

Then Fender went after PRS. The Silver Sky — John Mayer's signature guitar, the best-selling S-style that is not made by Fender — received a cease-and-desist. In June, Thomann, the world's largest music retailer, filed a lawsuit against Fender in response. The guitar industry, which had watched quietly for weeks, stopped being quiet.

What Fender Actually Won

The Düsseldorf ruling is narrower than Fender's subsequent behavior suggests. It applies to guitars manufactured, sold, or distributed into Germany and the European Union. It does not apply in the United States, where Fender already tried and failed to trademark the Stratocaster body shape in a separate proceeding that concluded with a court ruling that the design was "so common that it is depicted as a generic electric guitar in a dictionary." That ruling was won by the lawyer who is now representing the companies Fender is currently targeting.

The Düsseldorf ruling is also a default judgment, which means it reflects what happens when one party does not appear in court, not the outcome of a contested legal proceeding where arguments were heard and weighed. Default judgments are legally binding, but they are not precedent in the same way that contested rulings are. If Fender attempts to enforce this ruling against a company that shows up and fights, they will face arguments that have not yet been tested in any court.

Fender knows this. The speed and breadth of the cease-and-desist campaign — hitting boutique builders alongside major manufacturers, setting a May 25 deadline for responses — looks less like confident legal enforcement and more like an attempt to extract compliance before anyone has the resources or time to mount a real challenge.

The Problem With Claiming a Generic Shape

The Stratocaster body shape has been copied by virtually every guitar manufacturer on earth for roughly sixty years. This is not an exaggeration. The S-style body — double cutaway, contoured back, offset upper horn — appears in the catalogs of hundreds of companies across dozens of countries, at every price point from entry-level import to high-end boutique. It has appeared in this many places for this long because Fender either could not or did not stop it.

In the 2009 US trademark case, courts found that the proliferation of copies was itself the evidence that the shape had become generic. Fender's failure to protect the design earlier meant that by the time they tried, the design belonged to everyone. The same argument will be available to anyone who contests the Düsseldorf ruling: the shape has been freely used for so long, by so many manufacturers, with Fender's full awareness and occasional marketing acknowledgment of the copy culture, that asserting copyright now is retroactive in a way that courts have historically rejected.

There is also the question of consistency. Fender CEO Bud Cole said in a dealer address that Fender is not going after "all double cutaway or two horned electric guitar bodies," only close copies of the Stratocaster specifically. But Fender and Bird & Bird have not provided a specification of what features constitute a protected "Stratocaster design." Without that clarity, every S-style builder in the world is operating under legal uncertainty. That uncertainty is itself a tool — it creates compliance through fear without requiring Fender to actually define what they own.

The PRS Problem

The most revealing aspect of this campaign is the inclusion of PRS and the Silver Sky. The Silver Sky is not a Stratocaster copy in the way that a $150 AliExpress guitar is a Stratocaster copy. It has a different body contour, a different neck joint, a PRS headstock, different proportions, different hardware, and different inlays. It is Stratocaster-inspired, which is a different thing. John Mayer left Fender in 2014 precisely because he wanted to redesign the Stratocaster's DNA, not reproduce it.

If Fender is pursuing the Silver Sky, they are not going after clear infringement. They are going after competition. The Silver Sky is the best-selling non-Fender S-style guitar on the market. In 2025, it was the second most-sold guitar on Reverb, behind only the Fender American Professional II Stratocaster. Fender has a business reason to want it off the market that has nothing to do with intellectual property. Including it in this campaign makes the legal argument look thinner and the commercial motivation look more obvious.

What Happens Next

The lawyer who beat Fender in 2009 is already involved. Ronald Bienstock of Fox Rothschild, who led the class action defense that defeated Fender's previous trademark attempt, has sent a response letter on behalf of at least one company identifying multiple legal vulnerabilities in Fender's position. Thomann's lawsuit will force a contested proceeding. Other manufacturers with legal resources will follow. The default judgment that Fender built this campaign on will face challenges it was never designed to withstand.

Fender's CEO has already walked back the inventory destruction demand, saying it was "unfortunate." The deadline that was supposed to compel compliance by May 25 passed without a clear resolution. What looked like a confident legal campaign in March looks, three months later, like a company that got a ruling it did not fully think through and then moved too fast.

The Stratocaster body shape has been the foundation of the electric guitar market for seven decades. It has been copied, adapted, improved upon, and reinterpreted by builders all over the world. Some of those copies are cheap junk. Some of them are the guitars that serious players prefer to anything Fender actually makes. The design has been generic for most of its history not because anyone failed to notice it was valuable, but because it was too widely used too early to contain.

Fender built the most copied guitar in history. That is a genuine achievement. Trying to retroactively own it, starting with a default ruling in a German regional court and a campaign of cease-and-desist letters targeting boutique builders who are not Fender's competition, is a different kind of achievement — and not one that reflects well on seventy-plus years of being the guitar company the rest of the industry measured itself against.
