Chicago – Shermann “Dilla” Thomas, the self‑taught urban historian who tours the city on a purple‑and‑gold bus, is gearing up for a legal showdown over his popular merchandise slogan. The phrase “Everything Dope About America Comes From Chicago,” which appears on his shirts, mugs and other items, has attracted worldwide attention, including a recent feature on the BBC.
Trademark filing and opposition
Thomas began the trademark process in spring 2025, filing an application on May 12, 2025 with the help of trademark attorney India Rios of India Esquire. Until now, his applications for related marks—such as the name of his company, Chicago Mahogany, LLC—have faced no challenges.
That changed on April 21, 2026, when Dope Snow, a Swedish company that sells snow, ski and outdoor apparel, lodged an official opposition. Dope Snow, which registered its own marks for the words “dope” and “dopest” years earlier, argues that Thomas’s slogan infringes on its trademarks because it contains the word “dope.”
Legal experts weigh in
Rios, who filed Thomas’s applications, says the opposition is “ridiculous.” She notes that a successful dilution claim requires a “world‑famous” mark—examples include Coca‑Cola or Nike—something Dope Snow does not possess. “Most people have never heard of Dope Snow,” Rios added.
Rios also points out that trademark law obliges owners to enforce their marks, but that enforcement should be limited to cases where consumer confusion is likely. “When you take the two marks as a whole and you compare them against each other, they’re not the same,” she said. “It’s just the fact that his mark includes the word ‘dope.’ It’s almost like they’re trying to say that they have a monopoly on the word in regards to clothing and no one can use the word for clothing.”
Dope Snow proposed a coexistence agreement that would have required Thomas to withdraw from Trademark Class 25, the category covering clothing. Accepting that deal would have made it extremely difficult for Thomas to continue selling merchandise bearing his slogan.
Potential costs and community impact
Thomas estimates the legal battle could cost him at least $20,000, a sum he does not have readily available. “We’re going to keep educating people about Chicago, but I don’t have 20 Gs sitting around,” he said.
Attorney Erin Russell, an intellectual‑property litigator, concurs that the likelihood of consumer confusion is negligible. She also suggests that the 70 pending oppositions Dope Snow has filed against other “dope”‑related marks could demonstrate that the term is generic, potentially weakening the company’s claim.
Thomas’s perspective
Thomas sees the dispute as a broader cultural issue. “It’s just hilarious how this thing that Black American kids start saying in cities like New York and Chicago is now copyrighted by folks across the pond, and then they’re telling Black folks who created the term that they can’t include the term,” he said. He added that the slogan reflects a long‑standing local expression of pride, not a brand owned by an overseas company.
While the legal process is expected to take about two years, Thomas remains determined to protect his intellectual property and continue his educational tours, which have suffered from reduced grant funding in recent years.
What’s next?
The case will proceed through the United States Patent and Trademark Office’s opposition proceedings, after which either party may appeal to federal court. Both sides have indicated they will present detailed arguments on the Polaroid Factors, which assess the likelihood of consumer confusion.
Chicago residents who appreciate Thomas’s work can continue to support his bus tours and purchase merchandise bearing the slogan, thereby reinforcing the city’s cultural heritage while the legal battle unfolds.
