David Allison runs cheatcc.com, a site dedicated to posting cheat codes for video games. He recently sued a competitor, Crave Online Media, for copying his postings and replicating them on their website. He claims Crave Online Media violated his copyright in the postings.
The big question will be whether he actually owns copyright in the postings. He probably does own the copyright in his own original content, but he's going to have a tough time arguing that he has copyright in the actual cheat codes. First, the codes probably aren't his original works because they were created by the games' developers. Second, copyright doesn't protect underlying facts or ideas; it only protects how facts or ideas are expressed.
