Over the years, we've seen plenty of aggression from universities when it comes to trademark enforcement. The impetus for much of this was rulings nearly a decade ago that essentially gave universities far broader and more exclusive rights to their school logos. The fallout of those rulings became schools going after all kinds of uses and near-uses of those logos, including a strange war on pastries, and colleges going after high schools for using similar iconography.

The latter continues to the present. The latest version of this is Rutgers, in New Jersey, forcing a Louisiana high school to change its logo because it was essentially the same as Rutgers' famed "R" logo.
