What this record means
The record shows that “NINJA WARRIOR TRAINING ACADEMY” is an abandoned service mark – the application was filed by Real Life Ninja Academy Franchising, LLC on Aug 19 2020 and was abandoned on Jul 1 2021 after the applicant failed to respond to an Office action, which is the latest status event in the file. The only goods and services listed are in International Class 041 and cover conducting sports competitions, entertainment services such as parties, teaching and training in obstacle‑course and sport‑ninja activities. A similar name would raise the closest concern if used for any of those educational or entertainment services, because the record’s protection is limited to that specific scope and does not extend to unrelated goods or services. The prosecution history shows a non‑final office action in Dec 2020 followed by an abandonment notice in Jul 2021, but there are no oppositions, cancellations or court actions recorded, so the supplied history shows no enforcement activity. I'd treat this as a meaningful concern if you plan to offer ninja‑style training or related entertainment, but the abandonment means the USPTO no longer blocks the wording in other fields.
