What this record means
The record shows that “ELSA” is a live Principal Register registration (Reg. No. 2507317) owned by VALENTIN BIANCHI S.A.C.I.F., a corporation organized in Argentina, and it was renewed most recently on March 17 2022. The registration covers only wines (International Class 033) with a first use in April 1997, so a similar name used for wine or related beverage products would raise the closest record‑based concern. The record does not give the owner control over the word “ELSA” in other categories such as clothing, software, or services, and it does not extend to every possible use of the term. There is no prosecution history indicating a Supplemental Register filing, and the history contains no oppositions, cancellations, or other enforcement actions. I'd treat this as a meaningful concern if you plan to market wine under a similar name, but the risk is far lower for unrelated goods.
