What this record means
The record shows that the application for PONQUESITO has been abandoned, so the mark is not live or registered; the owner listed is Holsum de Puerto Rico, Inc., a corporation organized in Puerto Rico. The filing covered only one class—Class 030 for “Pound cake in slices,” with a first use date of Dec 1, 1984 and a use‑in‑commerce date of the same day. Because the protection is limited to that specific food product, a similar name used for anything outside sliced pound cake would present the closest record‑based concern, but the record does not give the owner control over every use of the word “PONQUESITO” in other contexts. The prosecution history shows an express abandonment filed on Dec 10, 2010, which is the latest meaningful status event, and no further maintenance or renewal dates are provided. The supplied history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a modest concern if you plan to market a food product similar to sliced pound cake under a comparable name.
