Jaime DeAnda Secures Federal Trademark Registration for ‘Jaime Y Los Chamacos’

SAN ANTONIO, Texas — In a significant development in the ongoing legal battle over the legendary Tejano group’s name, the United States Patent and Trademark Office (USPTO) has officially registered the trademark “Jaime Y Los Chamacos” to James (Jaime) DeAnda and Darlene DeAnda as of June 16, 2026, according to federal trademark records.

The registration comes just days after DeAnda’s arrest on a warrant connected to a court dispute involving the use of the Jaime y Los Chamacos name, adding another chapter to a years-long legal battle between the band’s founder and current Los Chamacos owner Roel Joslin.

Federal records show that an Extension of Time to Oppose filed by Joslin regarding the trademark application was ultimately terminated by the USPTO on May 24, 2026, clearing the way for the registration to move forward. The trademark application, originally filed in May 2025, was published for opposition in January 2026 after receiving approval from examining attorneys.

The newly registered mark covers entertainment services, including live musical performances by a band, and lists both Jaime and Darlene DeAnda as owners.

Long-Running Ownership Dispute

The trademark registration arrives amid competing claims over ownership of the Jaime y Los Chamacos and Los Chamacos names.

In January, Los Chamacos issued a public statement asserting that ownership and exclusive rights to both names had been awarded to Roel Joslin following an August 2025 court judgment in Jim Wells County. According to the band, the ruling granted Joslin ownership rights, awarded damages against DeAnda, and permanently prohibited him from claiming ownership of or using the Jaime y Los Chamacos name for his personal benefit.

At the time, Los Chamacos maintained that DeAnda’s federal trademark filings had not been approved and vowed to challenge the applications through legal channels.

Two days after the band’s statement, DeAnda released his own response disputing the claims. He argued that he had not received proper notice of the 2025 court proceedings and maintained that the Jaime y Los Chamacos name represented decades of commercial use tied directly to his career as the group’s frontman, accordionist, vocalist, and creative leader.

DeAnda also characterized the opposition proceedings before the USPTO as routine procedural matters that did not determine ownership of the trademark. At the time, he expressed confidence that the federal trademark process would continue moving forward.

Arrest Amid Ongoing Court Battle

The latest trademark development follows DeAnda’s arrest earlier this month after authorities alleged he failed to appear for a scheduled court hearing related to a Motion for Enforcement and Contempt of Court. Court filings cited in reports alleged that DeAnda continued using the Jaime y Los Chamacos name to promote performances despite prior court orders. He later posted bond and was released.

While the trademark registration represents a major victory for DeAnda in the federal trademark arena, it does not necessarily end the broader legal dispute between the two sides, which continues to play out in Texas courts.
