What this record means
The record shows that YELLOW is a live Principal Register service mark owned by YRC Worldwide Inc., a Delaware corporation, and it has been renewed as of the March 12 2019 status date. The registration covers “Domestic and international common carrier freight transportation by means of truck, air, or sea, and domestic and international freight forwarding services” in International Class 039, so a similar name used for any kind of trucking, shipping, or freight‑forwarding business would be the closest area of concern. The record does not give YRC Worldwide control over every possible use of the word YELLOW; it is limited to the goods and services listed. There is no prosecution history, so no Supplemental Register issue appears. The latest meaningful event is the renewal noted on the March 12 2019 status date, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a meaningful concern if you plan a name in the same transportation‑logistics space.
