The Services field in the Starfall Racers trademark application was stuffed with far too many different categories, including entertainment services and arcades/video games. That’s likely the crux of the issue with Starfall Education, and how both parties knew they’d win a case if brought to trial.
Stardust Racers is listed as amusement attraction, specifically a roller coaster. And that’s it. So unless Stradust Bowling has roller coasters inside, I think they’re in the clear now.
