The Fender Stratocaster Lawsuit, Explained
Fender won a copyright ruling on the shape Leo drew in 1954, then started mailing cease-and-desist letters to the builders who kept it alive. One of them landed on John Mayer’s guitar.

What Fender actually won
In March 2026, a court in Düsseldorf ruled that the Stratocaster body is not just a trademark but a “copyrighted work of applied art” under German and EU law. The case ran against a Chinese manufacturer that never showed up to defend itself, so Fender won by default. A judgment against an empty chair, but a real one: it makes selling or importing S-style copies across the EU a copyright matter, not just a branding dispute.
Fender’s law firm treated the ruling as a starting gun and began sending letters.
The letters
One reached LSL Instruments, a family shop in California that builds fewer than 500 guitars a year. The letter asked LSL to stop making S-style guitars, hand over sales data, destroy unsold stock, recall instruments already sold, and cover Fender’s legal fees. LSL opened a GoFundMe to pay lawyers and wrote that the shop “poses no threat to them in any way whatsoever.”
Then the campaign reached PRS, and the target was the Silver Sky: John Mayer’s signature model, confirmed by the Wall Street Journal in May 2026. PRS says it disagrees with Fender’s assessment and intends to defend the guitar.
Why the Silver Sky exists at all
Here is the part that turns a legal story into a guitar story. Mayer spent the 2000s as the most famous Stratocaster player alive. He asked Fender for years to evolve the instrument with him, the feel of his early-sixties Strats with the flaws engineered out. He could not get it built. “I tried to do something like this with Fender,” he said, “but I couldn’t create enough enthusiasm within the company for my vision.”
He left in 2014. Paul Reed Smith picked up the phone, and two years later the Silver Sky shipped. The forums called it an overpriced Strat clone until players actually held one. The affordable SE version topped Reverb’s year-end best-seller lists in 2022 and 2023, and Guitar World reports the Silver Sky has outsold the Stratocaster in recent years. Fender’s answer to that scoreboard arrived this spring, on legal letterhead.
What it means for players and builders
If you own a partscaster or a boutique S-style, nothing on your wall changes. The pressure falls on small builders who sell into the EU, where importing a close copy now carries copyright risk, not just trademark risk. For some shops that is the difference between a product line and a closed door.
Worth remembering: in 2009 Fender tried to register the Strat, Tele, and P-Bass body shapes as US trademarks and lost, in part because builders had copied those shapes in the open for half a century. The 2026 campaign is an attempt to re-run that fight through a friendlier law in a friendlier court.
The bigger question
Strip away the guitars and this is a fight about who owns a design, who gets to build on it, and what happens when a company reaches for lawyers instead of a workbench. That same question is landing on every creator right now as AI turns music, art, and identity into things that copy themselves. I wrote the full version of that argument, from Leo Fender’s bench to the economics of AI, in a longer essay.
