A three-year legal fight over the THE ISLEY BROTHERS trademark ended with a short court filing. On August 12, 2026, attorneys for Ronald Isley and the estate of his late brother Rudolph filed a stipulation of dismissal in the U.S. District Court for the Northern District of Illinois. The filing closed case No. 1:23-cv-01720 with prejudice, meaning the same claims cannot be brought again. Each side agreed to cover its own costs and legal fees.

The settlement disclosed no ownership transfer, payment or explanation of what either side conceded. As a result, the federal trademark registration remained in Ronald Isley’s name alone. The court docket ended without changing the registration, leaving the public record as the clearest guide to the dispute’s outcome.

The trademark history is especially relevant to working musicians. Ronald filed the application on November 2, 2021, claiming a priority date of 1954, when the brothers formed the group in Cincinnati. The U.S. Patent and Trademark Office registered the mark on August 16, 2022. Rudolph, a co-founder who stopped performing in 1989 but continued managing and licensing the group’s work, sued on March 20, 2023. He alleged that the brothers jointly owned the name through a common-law partnership and that Ronald applied “without the knowledge or approval” of his brother. Rudolph also alleged that Ronald made inaccurate statements under penalty of perjury. Rudolph died at 84 in October 2023.

Practical takeaway for artists: using a name commercially can create common-law trademark rights, but those rights depend on proving that audiences associate the name with your services. They may initially cover only a local market and established touring area. Registering with the USPTO can provide nationwide priority and a legal presumption of ownership. Before releasing music, booking shows or selling merchandise, artists should search for conflicting names, document first use and file early, because the application date can determine who has priority when another performer adopts a similar name.

What performing already earns you, and where it stops

Common-law trademark rights can protect an artist’s name without registration, but they are usually limited to the geographic markets where the name has been used commercially. A rapper who has sold out three venues in Houston and released music on Bandcamp may have a defensible claim in Texas, yet little protection in Georgia. That geographic gap fuels many band name disputes: artists can build legitimate audiences under the same name for years until a booking agent, streaming playlist, or national tour brings them into direct competition. Artists can reduce the risk by documenting releases, performances, merchandise sales, advertising, and the dates and locations of that use before choosing a name.

The founding members of the Sugarhill Gang experienced the consequences firsthand. Guy O’Brien and Michael Wright are widely known as Master Gee and Wonder Mike, the performers associated with “Rapper’s Delight.” They ultimately toured as The Rapper’s Delight Experience instead of using the group name featured on the record. “We also have the trademarks to our stage names Master Gee and Wonder Mike,” O’Brien told Fox News, while discussing a settlement involving royalties and licensing. He described the dispute as “a constant struggle.” Their experience illustrates a key point: performers may secure trademark rights in their individual stage names without controlling the name of the group that made them famous.

The three classes that decide what you actually own

A trademark registration is a fence around a word used for specific goods and services, and the USPTO sorts those into numbered international classes you pay for separately. Class 41 covers live performance and entertainment services, which is the class that protects you as a touring act. Recorded music, the downloads and the physical formats, sits in Class 9. Clothing sits in Class 25, which is where merchandise lives and where most bootleggers do their business.

Artists routinely file in one class, usually 41, and two years later find a clothing company in another state selling hoodies under their name, with a clean Class 25 registration of its own. Deciding which classes you need is a budgeting question rather than a legal one. For a developing act, Class 41 comes first, Class 25 comes when merchandise starts paying for itself, and Class 9 comes when a distributor asks.

What the filing costs in 2026

The USPTO restructured its trademark fees on January 18, 2025, and the numbers on the current fee schedule are the ones to budget against. That schedule sets a base application fee of $350 per class for an application meeting the office's requirements. Filing in Class 41 and Class 25 together therefore starts at $700, and adding Class 9 puts the base cost at $1,050 before a lawyer bills an hour.

The surcharges are where budgets break. An application missing required information carries an extra $100 per class. Writing your own description of goods and services, rather than pulling wording from the office's prepared list, adds $200 per class. Every additional thousand characters beyond the first thousand adds another $200 per class. An artist who files three classes with custom descriptions has spent $1,650 before the examining attorney has read a word.

Filing before the name is working

Somebody with a name chosen and a project unfinished files on an intent-to-use basis, which reserves the filing date and defers the proof. That path adds its own line items: the statement of use that eventually shows the mark working in commerce runs $150 per class, and each extension of time while the release slips runs $125. A petition to revive an application abandoned because a deadline passed costs $250, which is the cheapest expensive lesson in the schedule.

Where applications die

The most common cause of death is that the words do not do the job trademarks do. Cardi B learned this in public when the USPTO refused her application for OKURRR, the catchphrase she had made unavoidable. The examining attorney found the phrase to be a "commonplace term, message, or expression widely used by a variety of sources that merely conveys an ordinary, familiar, well-recognized concept or sentiment." That refusal also flagged a likelihood of confusion with an existing registration, WORRY ABOUT YOUR OWN KID OKURRRRT. Popularity was the problem. A phrase everyone says identifies no seller, and Cardi B could not register her way around that.

The second cause is somebody else's name: Section 1052(c) of the Lanham Act bars registering a mark that consists of a living person's name without written consent. The Supreme Court settled that provision's constitutionality on June 13, 2024, holding in Vidal v. Elster that "the Lanham Act's names clause does not violate the First Amendment." At issue was a political slogan on shirts, but the rule reaches any stage name built on somebody else's, and the consent has to be on paper.

What will not sink an application is language that offends an examiner. The Court struck the Lanham Act's disparagement bar in 2017, in a case brought by the founder of a band, the Slants, whose members had chosen a slur about themselves on purpose. Two years later it struck the bar on immoral and scandalous marks. Rap names that would have died at the office in 2010 register now.

The calendar that starts after the certificate

Registration is a subscription rather than a purchase, and the renewals are the part artists forget. A declaration of continued use under Section 8 comes due between the fifth and sixth year at $325 per class, with a $100 per class charge if you slide into the grace period. At ten years, and every ten years after, the combined Section 8 declaration and Section 9 renewal runs $650 per class. A Section 15 declaration at $250 per class makes the registration incontestable after five years of continuous use. Most artists have never heard of it, and it is the filing that hardens the asset.

Those numbers land differently once you multiply them by classes. Three classes maintained for twenty years runs roughly $4,875 in office fees alone. That is less than a single video and more than most independent artists have set aside for anything that does not make noise.

What the Isley docket says about groups

Judge Thomas M. Durkin denied Ronald Isley's motion to dismiss on August 23, 2023, finding enough on the record to infer a two-man partnership between the surviving brothers. O'Kelly Isley Jr. had died on March 31, 1986, and his half interest had passed to them. A court willing to infer a partnership is not the same as a court ordering a registration changed, and three years later the registration had not changed.

Groups that survive their own success write the ownership down early, in a document that names who holds the mark, what happens when a member leaves, and who may perform under the name afterward. Artists who read our accounting of what a thirty-dollar beat lease does and does not transfer will recognize the pattern. Trademark ownership follows the rule that governs everything else here: the paperwork signed while everyone is friendly decides what happens when nobody is. The same logic runs through the reversion window we mapped in the thirty-five-year termination right, where one sentence written in 1986 determined who controlled a catalog four decades later.

Ronald Isley's application took nine and a half months to register. The fight over it took just under three and a half years and produced no change to the certificate. Whoever files next will pay $350 a class and get a date stamp.
