Boise State got a trademark for their crappy blue turf for collegiate sports a decade ago. What I didn't know is they assert common-law rights to ANY non-green college field and expect written consent from anyone that does it. They even seem to expect it from high schools, too and they specifically tell them in any approvals they are not allowed to let college teams use them (Might explain why we didn't practice on the blue field).
Apparently SUNY-Morrisville didn't get permission when they installed their black turf and pissed them off. Story has a quote from Boise attorney in it:
“While Boise State has not yet opted to enforce its famous and registered blue turf trademark against any non-blue turf or other non-blue usage,” Brad Frazer, BSU’s outside trademark attorney, told Sportico in a statement, “a determination as to whether a non-blue usage rises to the level of trademark infringement requiring a license, enforcement or both is a case-by-case determination.”
Gimmick school.
