J. K. Rowling's really getting down to business now; she's even trademarked the names "Harry" and "Potter":
From Shelf-Awareness (scroll down): "Lawyers for J.K. Rowling have indicated in public filings that the author of the Harry Potter series has directed them to use their "full powers" to protect the reading experience of fans of her iconic work.
To that end, legal staff are continuing the suit against RDR Books over the Harry Potter Lexicon and will remain vigilant in opposing in court any other similar infringement on Rowling's intellectual property.
More strikingly, in an additional new move, the lawyers have copyrighted and trademarked the words "Harry" and "Potter" and will protect those brands. In a statement, the author said, "Muggles everywhere should be happy that I have been so restrained. Some thought I should protect every word I wrote in the seven Harry Potter volumes."
