What this record means
The record shows that “AMERICAN NINJA WARRIOR” is an abandoned application (status dead) owned by Tokyo Broadcasting System Television, Inc., a corporation organized in Japan, and it never reached registration because no Statement of Use was filed after the Notice of Allowance on August 28 2018; the abandonment notice was issued on October 4 2021. The only goods listed are “dietary and nutritional supplements” in International Class 5, so the closest area of concern would be any similar name used on health‑related products or supplements. The record does not give the owner control over the words “American,” “Ninja,” or “Warrior” in other industries or for unrelated goods, and it is not on the Supplemental Register. The latest meaningful event is the abandonment notice on October 4 2021, and the supplied history shows no oppositions, cancellations, or other enforcement actions. I'd treat this as a moderate concern if you plan a similar mark for supplements, but the risk drops sharply for unrelated product categories.
