A Fender Stratocaster is the kind of guitar musicians name. Since the 1950s, guitarists and technicians have prized the Strat’s capabilities, mastering and modifying it to produce some of the defining sounds of classic rock music. But does that give the Fender Musical Instruments Corporation control over the shape of electric guitars in general?
In the U.S., the guitar’s famous S-shape is considered generic, and manufacturers have used it for years. However, in a recent default judgment, a German court held that the Stratocaster body shape has copyright protection. Fender has since sent cease-and-desist letters to other guitar manufacturers worldwide, provoking protests, indignation, and legal action.
The History of the Instrument
Electric guitars generally share two major departures from the traditional acoustic guitar: the solid body and the traditional cutaway. The electric guitar’s solid body relies on the electric amplifier and speaker for its sound, reducing resonance and increasing its resistance to feedback. Almost all electric guitar bodies use at least one cutaway to allow players to reach all the frets more easily.
Luthiers (guitar builders) and tinkerers created the electric guitar’s features over decades of trial and error. Inventor Leo Fender, working from his earlier Telecaster model, introduced the Stratocaster in 1954. Fender did not invent the cutaway or the solid body, but the Stratocaster did combine an asymmetrical double-cutaway style with an S-shaped, contoured solid body, one of the Strat’s many innovations.
The company has since updated its materials and specifications, producing variations and signature models, but the classic Stratocaster body shape itself has remained largely unchanged since.
The Stratocaster Under U.S. Law
In the U.S., a creator can protect their rights to profit from an invention by securing a patent. Patents give inventors exclusive rights, but they are time-limited to allow for eventual public use. Leo Fender received a patent for the tremolo mechanism (or “whammy bar”) of the Stratocasterin 1956. Once the patent expired, other manufacturers were free to create imitation Stratocasters — and they did. Lower-cost models flooded the market from the 1970s onward.
In the 2000s, the Fender Musical Instruments Corporation turned to trademark law. Trademarks protect symbols, words, or designs used “in commerce to identify and distinguish the goods of one manufacturer or seller” from those sold by others. However, a creator cannot claim trademark on a “generic” term or design. When a trademark enters general use as a description for a product, it loses any legal protection it may have had. The terms “aspirin,” “trampoline,” and “zipper” were all once trademarks.
The Fender corporation attempted to trademark the Stratocaster body shape as an outline, together with the shape of its Telecaster and Precision Bass. By that point, guitar builders had been using all three shapes for many years. Guitar sellers and manufacturers formally opposed Fender’s trademark filing, presenting evidence that the Stratocaster’s shape was genericized and widely in use. The USPTO Trademark Trial and Appeal Board rejected Fender’s trademark applications in a 2009 opinion, stating that “[the] record does not support a finding that consumers … would or could identify the source of a particular guitar based solely on the outline of these body configurations.”
Fender’s Claims Under E.U. Law
Fender’s current controversies stem from its reliance on European intellectual property law. American law recognizes copyright on tangible artistic expressions, but “useful” items generally belong to patent law. Germany and other European countries recognize copyright on “works of applied art”: useful items infused with creative expression.
In 2025, Fender sued Yiwu Philharmonic Musical Instruments in the Landsgericht Düsseldorf (Regional Court of Düsseldorf) for selling Stratocaster knockoffs on AliExpress. The Chinese company did not file an appearance in the case. According to legal critic the Blues Lawyer, it likely refused to recognize the German court’s jurisdiction.
The Düsseldorf court issued a default judgment; since Yiwu did not appear, it took Fender’s facts as admitted. The court held that Fender did have a copyright of applied art on the Stratocaster body shape. Comparing the S-shape to a dancer or a reaching torso, the court called it “an outstanding intellectual creation that reflects [Leo Fender’s] personality.” (The quoted text is machine-translated; see the opinion in German.)
Fender then began sending cease-and-desist letters to established guitar manufacturers and dealers throughout the world. Reportedly, the letters to manufacturers did not just demand a halt to sales, but claimed the right to force recalls and even destruction of existing stock. Maryland-based PRS Guitars received one, apparently over its well-known Silver Sky model, and the multinational Yamaha Instruments also received a letter. When LsL Instruments, a small California family firm, got one, it had to hold a GoFundMe to raise legal funds.
Legal experts do not agree that the German ruling will give Fender the rights it asserts against other companies besides Yiwu. The default judgement was limited to the specific dispute with Yiwu, and it forbade Yiwu from selling those specific guitars in Germany. But the judgment does not have a binding effect on other courts. Even so, Fender has pushed forward with its claims.
Thomann’s Challenge to Fender
One of Fender’s cease-and-desist letters went to Thomann, a major German instrument dealer and manufacturer of the Harley Benton ST-Style. Thomann promptly filed a Declaration of Non-Infringement in the Landsgericht Düsseldorf, requesting a ruling that it was not in violation of copyright. Now Fender has filed its own copyright infringement lawsuit against Thomann in the same court.
Fender’s CEO has since tried to publicly soften the company’s earlier positions and demands, claiming that it does not mean to claim the S-shape alone, but only “close copies.” However, Fender continues to pursue enforcement, and not without cost. Fender’s tactics have been profoundly unpopular with dealers, collectors, and musicians. As industry watcher Saul Hudson writes, “[Fender’s] emotional connection is a commercial asset of enormous value, and it is not unlimited.” Loss of goodwill can create permanent damage to a brand — perhaps more than lawsuits can replace.
