Not a lawyer, but in this particular case it appears they reaffirmed the lower court stating the vendor couldn't sell products with trademarked Greek organization lettering (though he could make up ones using the Greek alphabet as demonstrations) and that they could continue to sell their "double raised crest backing" paddle which the group was requesting they be banned from doing. So the trademark was protected it would appear. Even though the infringing company makes a good case (laches) for selling said products without regard from the fraternities/sororities for decades (in fact, they were selling to these organizations, so they were generally aware of the company's existence and practices).
