Zombie brands

This is a new one. I was trying to find the Xerox corporation graveyard ad and found references to it (no visuals). One of the websites was a World Intellectual Property Organization newsletter written by Timothy J. Lockhart. He writes about the death of trademarks--nothing new there--but at the end of the article he talks about Zombie brands (formerly known as ghost or orphan brands). These are marks that "die" (the registration is allowed to lapse, is sold, etc.) but are resurrected for the same or similar products. Some examples are WHITE CLOUD toilet paper--acquired by Procter & Gamble, but was phased out because P&G also owned CHARMIN toleit paper, and then sold to Wal-mart as a private label. A company is looking into looking into resurrecting the BRIM coffee brand, but for caffinated as well as decaf coffee. More info is at http://www.wipo.int/wipo_magazine/en/2009/06/article_0010.html
