( CNN ) -- When Uncle Si Robertson declared on `` Duck Dynasty '' that `` My favorite color is camo '' it spurred a line of clothing sold to the A & E show 's fans , according to a federal lawsuit filed Tuesday . But the cable channel 's sales of T-shirts , hoodies and other apparel bearing that quote violate a trademark owned by Hajn , a Florida company that was already marketing `` My Favorite Color is Camo '' merchandise , the civil complaint said . The company claims it registered the trademark and put it on shirts , pants , hoodies , hats , magnets , stickers and bumper stickers in 2011 , a year before the `` Duck Dynasty '' reality series began airing on A & E . `` A & E 's conduct constitutes clear acts of unfair competition that risks considerable consumer confusion in that customers purchasing apparel from A & E believe that these goods are affiliated , sponsored , endorsed or related to Hajn , '' the suit said . `` Alternatively , A & E 's conduct constitutes reverse palming off , in that consumers believe that Hajn is selling Duck Dynasty related apparel . '' Hajn lawyers sent a cease-and-desist letter to A & E in early June , but the network is still marketing the men 's , women 's and children 's clothing with the trademarked slogan , the lawsuit said . A & E sells the apparel through merchandising deals with retail outlets such as Sears , Wal-Mart , Kohl 's , Sports Authority and Target , as well as online , the complaint said . `` A & E generated $ 400 million in revenues from sales of Duck Dynasty branded merchandise at Wal-Mart in 2013 alone , '' the suit said . The lawsuit demands that A & E stop selling `` My Favorite Color is Camo '' apparel and pay damages to Hajn . Lawyers for A & E have not filed a response in court . `` We do n't comment on pending litigation , '' A & E publicist Dan Silberman told CNN Wednesday .
