What this record means
The record shows that “SWEET AFTON” is a dead Principal Register registration that expired because it was not renewed, with the last status change recorded on Sep 9 1987; the owner listed is P.J. Carroll and Company Limited, an Irish corporation, and the mark covered cigarettes in International Class 34, first used in commerce in February 1957. Because the registration is no longer active, the USPTO record does not give the owner control over every possible use of the words “Sweet Afton,” but the historical claim to cigarettes means a similar name used on tobacco products would raise the closest record‑based concern. The prosecution history contains only the expiration entry and no oppositions, cancellations, or other enforcement actions, so the supplied history shows none. I'd treat this as a meaningful concern if you plan to use a comparable name for cigarettes or related tobacco goods, while other product categories would be farther from the scope shown here.
