What this record means
The record shows that “FLOR DE LECHE” is an abandoned application, filed on April 19 2011 by the individual owners Jeronimo Pliego and Gonzalo Pliego, and the USPTO marked it dead on March 14 2012 after the applicant failed to respond to an Office action. The only goods listed are “Dairy products excluding ice cream, ice milk and frozen yogurt; Milk products excluding ice cream, ice milk and frozen yogurt” in International Class 029, so a similar name used for food items in that category would present the closest record‑based concern. The record does not give the owners any control over the wording in unrelated markets or product types. The prosecution history shows a non‑final action issued in August 2011 followed by an abandonment notice in March 2012, confirming the application never reached registration. No enforcement actions such as oppositions or cancellations appear in the supplied history. I'd treat this as a meaningful concern if you plan to use the same name for dairy or milk‑related foods, but the risk drops sharply for other goods or services.
