sentences:  On November 13, 2006, the Dykes on Bikes won the battle to trademark the name, having struggled since 2003 to persuade the PTO that "dyke" was not offensive to the lesbian community.In 2005, after a prolonged court battle involving testimony on the word's changing role in the lesbian community, the Trademark Trial and Appeal Board permitted the group to register its name.The defense noted that during the time period from 2000 to 2005 the PTO had approved marks for "Crippled Old Biker Bastards", "Biker Bitch", "Whore", and "Evil Pussy" as well as "TechnoDyke", "Homo Depot", "Queer Shop", "Queer Eye for the Straight Guy" and "Queer as Folk".
