Three Recurring Disputes
Instrument manufacturer litigation follows three patterns. Trademark disputes concern whether an iconic body shape can be protected as a source identifier. Counterfeit enforcement targets replicas sold through online marketplaces.
Pricing disputes concern minimum advertised price policies restricting how low retailers may advertise, which raises competition questions.
Shape trademarks can become generic
A body shape used by many makers over decades may cease to identify a single source. Trademark offices have refused registration of some iconic guitar shapes on that basis, holding that consumers no longer see the shape as indicating one manufacturer.
The Legal Framework
Trade dress protection requires that a shape identify source and not be functional. For instruments the functionality question is real, since body contours affect balance, comfort and resonance, and functional features cannot be monopolised through trademark.
Counterfeit enforcement proceeds under trademark law, with marketplace liability depending on knowledge and response. Platforms generally avoid liability where they act on notice, which is why enforcement is a continuous takedown process rather than a single case.
Minimum advertised price policies are generally lawful as unilateral policies, but agreements between manufacturer and retailers fixing resale prices attract antitrust scrutiny, and the distinction between a policy and an agreement is where disputes arise.
What Buyers Should Know
Counterfeit instruments are common on marketplaces at prices that appear plausible rather than obviously too low. Serial number verification with the manufacturer, and buying from authorised dealers, are the reliable protections.
A counterfeit is not merely a cheaper instrument. It typically has no warranty, no resale value, and where the buyer resells it, they may themselves face trademark exposure.
Verify serial numbers before buying used
Manufacturers can confirm whether a serial number matches a genuine instrument and its production details. That check takes minutes and is the single most effective protection when buying an expensive used instrument privately.

Musical Instrument Lawsuits: Shape Trademarks, Counterfeits and Pricing: Frequently Asked Questions
Answers to the most common questions about this case and your legal options.
Can a guitar body shape be trademarked?
Sometimes, but shapes used by many makers over decades may be held generic, and functional features affecting balance or resonance cannot be monopolised.
How is counterfeiting enforced?
Through trademark law, with marketplaces generally avoiding liability where they act on notice, making enforcement a continuous takedown process.
Are minimum advertised price policies legal?
Generally yes as unilateral policies, though agreements between manufacturer and retailers fixing resale prices attract antitrust scrutiny.
How do I avoid buying a counterfeit?
Verify the serial number with the manufacturer and buy from authorised dealers. Counterfeits are often priced plausibly rather than obviously low.
Why does a counterfeit matter beyond quality?
It typically carries no warranty and no resale value, and reselling one can expose the seller to trademark liability.
