The NFL is appearing to back off its trademark ownership claims to the phrase 'Who Dat' and the fleur-de-lis logo, now they are saying it is challenging the sale of items only "when those products contained or are advertised using other trademarks or identifiers of the Saints." The controversy began when the NFL sent letters to New Orleans shops ordering them to stop selling merchandise that it said violates state and federal trademarks held by the New Orleans Saints.

as i said when this first came out, the nfl can't trademark Who Dat or Who Dey or Dawg Pound or any of the other phrases that nfl FANS come up with to support their teams. This had fail written all over it from the beginning.
