What this record means
The record shows that the mark SEA was filed by individual Lorin Sandretzky on November 20, 2014, but it was abandoned on October 8, 2015 after the applicant failed to respond to an Office action, so the application is no longer live or registered. The only goods and services listed are “Entertainment services, namely, participation in football events; fan clubs; organization of sports events in the field of football” in International Class 041, which means a similar name would raise the closest concern for anything tied to football‑related entertainment or fan activities. The record does not give the owner control over every use of the word “SEA” in other contexts. The prosecution history shows a non‑final action issued in March 2015 and the subsequent abandonment notice in October 2015, but there are no later maintenance filings or renewal dates. No oppositions, cancellations or court actions appear, so the supplied history shows no enforcement activity. I'd treat this as a modest concern if you plan a football‑related service under a similar name, but the risk is limited to that specific area.
