You can't trademark the word sex and you can't trademark sex furnitures too because they are common words.For a trademark you have to use something like sex dollars,sex money,blah which isn't used by others.You still can use parts of the trademark if they are a common word.The lawsuite is just against the use of brands in connection with competitiors,playboy already won.That's like I would make an adword for GFY but link to XBiz
Adwords never really got me money so I don't care
