What this record means
The record shows that the WEEKEND NINJA WARRIOR service mark is dead, abandoned by its owner Jesse Leone, an individual, after publication. This mark covered gymnasiums in the education and entertainment class, so a similar name would create the closest concern in this area. The record does not establish control over every use of the wording. The prosecution history shows a standard examination sequence, culminating in the applicant filing an express abandonment after the mark was published for opposition. The latest meaningful event was the abandonment notice mailed on January 24, 2017. The supplied history shows no visible enforcement activity. I'd treat this as a meaningful concern if considering a similar name for a related service, as it suggests the owner was once invested in protecting this mark, even if they ultimately abandoned it.
