What this record means
The record shows that “AMERICAN NINJA WARRIOR” is a live, registered service mark owned by Tokyo Broadcasting System Television, Inc., a corporation organized in Japan. The registration, issued on October 6 2020, covers class 041 services that include arranging and conducting athletic competitions, entertainment in the nature of obstacle‑course racing games, and providing a website with fitness information and advice. Because the listed services focus on sports‑related entertainment and fitness content, a similar name used for those kinds of activities would create the closest record‑based concern, while uses in unrelated fields would be farther from the scope shown here. The record does not give the owner control over every possible use of the words “American Ninja Warrior.” No prosecution history is present, and the mark sits on the Principal Register, so no supplemental‑register sequence appears. The latest meaningful event is the registration date of October 6 2020, and the supplied history shows no oppositions, cancellations or other enforcement actions. I'd treat this as a meaningful concern if you plan a comparable name in the same fitness‑entertainment space.
