Boss Beats Behringer: Judge Dismisses Polyphonic Tuner Patent Lawsuit

In a major development for the guitar gear industry, a US federal judge has officially dismissed the high-profile patent infringement lawsuit brought by Behringer’s parent company, Empower Tribe, against Roland-owned Boss.

The legal battle centered around polyphonic guitar tuning technology.

Empower Tribe claimed that Boss infringed on its intellectual property by implementing polyphonic tuning modes into several of its flagship multi-effects processors.

However, the court completely rejected the claim, ruling that the patent in question was fundamentally ineligible under US patent law because it relied on an abstract concept.

The Core of the Dispute: TC Electronic PolyTune vs. Boss Multi-Effects

The lawsuit, which was filed last year, targeted a specific polyphonic tuning feature found in a lineup of popular Boss products, including the:

• Boss GT-1000

• Boss GT-1000CORE

• Boss GX-100

• Boss GX-10

Empower Tribe—the umbrella company for both Behringer and TC Electronic—argued that these units infringed on the proprietary technology used in the critically acclaimed TC Electronic PolyTune.

The PolyTune revolutionized the market by allowing guitarists to tune all six strings simultaneously, rather than one string at a time (monophonic tuning). Behringer’s legal team alleged that the Boss multi-effects versions were a “knock-off” of this patented system.

Why the Judge Sided with Boss

In response to the lawsuit, Boss filed a motion to dismiss, arguing that Behringer’s patent lacked a genuine “inventive concept.”

Under US patent law, inventors cannot patent abstract concepts, physical phenomena, or the simple application of generic hardware to a routine problem.

The “Generic Component” Pitfall

Behringer’s defense admitted that the PolyTune system utilized “generic computer components.”

However, they countered that the “inventive concept” lay in the specific, non-conventional arrangement of those pieces—specifically, creating a mode-dependent display that seamlessly toggles between user-selectable monophonic and polyphonic tuning modes.

Ultimately, the court was unconvinced. The judge granted Boss’s motion, dismissing the case with prejudice.

“Nothing in the claim limitations, considered individually and together as a whole, is sufficient to transform the Asserted Claims into a patent-eligible invention,” the court’s decision stated, agreeing with Boss that the claims “only describe generic computer components.”

Because the case was dismissed with prejudice, Behringer cannot simply rewrite the same lawsuit.

The judge further noted that granting the plaintiffs leave to amend their arguments would be “futile,” declaring patent ineligibility a fundamental defect that cannot be cured.

While Empower Tribe technically still holds the patent, this ruling sets a severe precedent that effectively renders it unenforceable in future litigation.

A History of Legal Clashes: Behringer, Boss, and the Gear Community

The dismissal marks a definitive loss for Behringer, a company that has frequently drawn scrutiny from the wider guitar gear community over its aggressive approach to product cloning and trade dress.

This isn’t the first time these two industry titans have locked horns in a courtroom:

• 2005: Boss sued Behringer over the physical appearance and chassis design of its budget stompboxes. That case was eventually settled out of court under confidential terms.

• Recent Controversies: Behringer recently faced a legal clash with Klon, LLC over a clone of the legendary Centaur overdrive pedal. The Behringer version initially replicated the original’s artwork and shared its name before being rebranded to “Zentara” with altered graphics. That suit was also eventually dismissed.

With this latest ruling, Boss secures a massive victory, ensuring that its flagship multi-effects processors can continue utilizing polyphonic tuning without further legal interference from its rivals.
