Daddy Yankee Files Federal Lawsuit Over Trademark Ownership
By Ferraiuoli LLC

Puerto Rican artist Ramón Luis Ayala-Rodríguez, professionally known as Daddy Yankee, has filed a lawsuit in the U.S. District Court for the District of Puerto Rico against his ex-wife, Mireddys González-Castellanos, seeking confirmation of his exclusive ownership of the registered trademarks “Daddy Yankee” and “DY.” The complaint requests declaratory relief and injunctive measures to prevent alleged interference with the commercial use of the marks.
According to the filing, Ayala-Rodríguez began using the name “Daddy Yankee” and the initials “DY” in the 1990s in connection with musical recordings, live performances, and related merchandise. The trademarks were initially registered through El Cartel Records and were later assigned to him following the dissolution of the company. The lawsuit states that González-Castellanos does not hold individual ownership rights in the marks.
The complaint further alleges that González-Castellanos issued a cease-and-desist letter asserting rights over the trademarks and filed submissions before the United States Patent and Trademark Office (USPTO) challenging certain trademark applications on the basis that they lacked her authorization. Ayala-Rodríguez contends that these actions interfere with his ability to manage and exploit the marks in commerce.
The lawsuit seeks a judicial declaration affirming his status as the lawful owner of the trademarks and an injunction barring González-Castellanos from asserting claims or taking actions that would restrict their registration, maintenance, or commercial use.
