Boise State understandably values its role as an innovator in the use of bright blue turf for its football stadium. In fact, the university reckons that its blue turf is such an integral part of its identify that it applied for and received a federal trademark registration for the word mark “Blue Turf,” for “entertainment services, namely, the presentation of intercollegiate sporting events and sports exhibitions.” Boise State has a further design mark registration, depicting a blue football field. (Boise State’s web site says that the university has a federal trademark registration on “the color blue as applied to turf” but it’s unclear to which registration that statement refers.) With no accounting for taste, a limited number of other schools, including high schools, have begun adopting non-traditional colors for their football fields, including the color blue. The biggest quandary for these blue-field adopters may not be dealing with retinal overload, but rather in determining how best to refer to their new blue turf. The phrase “blue turf” naturally springs to mind, but according to some news reports Boise State asks that other users of blue turf fields not use that phrase in their merchandising and promotion efforts. From a classical view of trademark law, one might be hard pressed to argue any likelihood of consumer (fan) confusion surrounding competing uses of “blue turf.” However, if the heavy hand of prospective trademark infringement limits the number of blue fields put into use, who can say Boise State’s blue-turf trademarks are a bad thing?
