The years-long trademark dispute between Gibson and Armadillo (parent company of Dean Guitars) has finally reached its conclusion. In a pivotal February 2026 ruling, the presiding judge solidified a mixed bag of results for both guitar manufacturers.
While Gibson successfully secured a permanent ban on several flagship Dean models and a six-figure financial payout, it suffered a permanent blow to its intellectual property: the court firmly denied Gibson’s appeal to overturn a previous ruling that deemed its iconic ES body shape as generic.
This follows news earlier today that Fender successfully secured broad legal protection for the iconic Stratocaster body in Germany and the EU.
The ES Body Shape Stays Generic
The beginning of the end of this legal saga began in March 2025, when a jury reasserted Dean’s initial defeat but also ruled that Gibson’s trademark for the ES body shape had become generic. Gibson immediately made its intent to appeal this decision clear.
However, in a filing made last month, Judge Amos L. Mazzant formally struck down the appeal, ensuring no new trial will be held regarding the ES trademark.
“The Court finds that the jury’s verdict that the ES Body Shape Design was generic as of 1996 is not against the great weight of the evidence,” Judge Mazzant stated in the filing. “Plaintiff is again asking the Court to substitute its wisdom for the collective wisdom of the jury – the Court refuses to do so.”
Financial Penalties and Permanent Bans
Despite losing the ES trademark battle, Gibson’s legal victory carries significant weight. The jury found that Dean/Armadillo counterfeited several Gibson trademarks. As a result:
-
Banned Models: Dean is permanently barred from advertising or selling the Dean Gran Sport, Dean V, and Dean Z guitars, which were found to infringe on the Gibson SG, Flying V, and Explorer, respectively.
-
The Payout: While the jury awarded Gibson only $1 in direct damages, Dean has been ordered to pay $168,399.22 in legal fees.
-
Accruing Interest: The judge denied Gibson’s request to triple the damages to over $500,000, calling it unnecessarily punitive. However, Gibson may charge a daily interest rate of 3.61% on the legal fees, compounded annually from the final judgment date of September 22, 2025.
-
Court Costs: All incurred court costs have been adjudged against Armadillo, adding an undisclosed but likely substantial amount to their financial burden.
Gibson ES Series
Gibson’s ES series is traditionally divided into three construction types: Hollow-body, Semi-hollow (featuring a solid center block), and Thinline.
Core Modern & Historic Models
| Model | Type | Notable Features |
| ES-335 | Semi-Hollow | The “Gold Standard.” Center-block design to reduce feedback. |
| ES-330 | Fully Hollow | Similar look to the 335 but no center block; usually features P-90 pickups. |
| ES-339 | Semi-Hollow | A scaled-down version of the 335, closer to Les Paul dimensions. |
| ES-345 | Semi-Hollow | Upgraded 335 with parallelogram inlays and (historically) a Varitone switch. |
| ES-355 | Semi-Hollow | The top-of-the-line “Custom” version: ebony board, block inlays, and gold hardware. |
| ES-175 | Fully Hollow | The classic deep-body jazz box with a sharp Florentine cutaway. |
Expanded List of ES Variations
Gibson has produced dozens of ES iterations since the 1930s. Some are student models, while others are high-end collector pieces:
-
Entry & Student Models: ES-100, ES-120T, ES-125, ES-130, ES-135, ES-140 (3/4 size).

-
Marcus King ES-345: A popular 60s-spec reissue.

Why the “Generic” Ruling Matters
While anyone can now technically manufacture a guitar with the double-cutaway silhouette of an ES-335, Gibson still holds the rights to:
-
The Headstock: The “Open Book” or “Mustache” headstock shape remains protected.
-
The Name: You cannot legally market a third-party guitar as an “ES-335” or “Gibson ES.”
-
International Markets: The generic ruling currently applies to the United States; Gibson still maintains strict IP control in the EU and other territories.
Frequently Asked Questions (FAQ)
Can other guitar brands legally copy the Gibson ES body shape now?
Yes, but with major caveats. Because the ES body shape is now legally generic in the United States, litigation concerning clones cannot rely solely on the body outline. However, Gibson still protects its other IP heavily. The iconic “open book” headstock design and the “ES” word mark remain fiercely guarded trademarks. Furthermore, Gibson still holds the rights to the ES body shape in other territories, including the EU. Consequently, attempting to market a direct 1-to-1 ES-335 clone remains incredibly risky for third-party builders.
What does this final ruling mean for the future of Dean Guitars?
The immediate impact is largely financial, with Dean on the hook for over $168,000 plus interest and court costs. From a product standpoint, the loss of the V and Z models—which were historically flagship shapes for the brand—forces a major lineup adjustment.
Dean has already begun pivoting, focusing recent marketing efforts on its ML body shape and new signature models (such as those for Kerry King). While not the death blow some industry insiders predicted, this ruling compounds several years of turbulent leadership and shifting artist rosters for the company.
Conclusion
The final gavel drop on the Gibson vs. Dean lawsuit sets a complex precedent for the guitar industry. Gibson successfully defended its core solid-body shapes—the SG, Explorer, and Flying V—proving it will aggressively and successfully litigate against unauthorized lookalikes.
However, the loss of the ES body shape serves as a stark reminder to legacy manufacturers about the limits of trademark enforcement when a design becomes ubiquitous over decades.
While Dean survives to build another day, both companies walk away from this multi-year battle permanently altered.
