Of course, as noted in the article, the copyright claim against MySpace makes no sense for a variety of reasons, starting with the fact that you can't copyright the name of a company. Second, MySpace is clearly protected by the safe harbors of the DMCA. The guy even tries an "inducement" claim against MySpace, which only serves to highlight how ridiculous the concept of making secondary copyright infringement against the law is: people will keep trying to stretch it. As for the trademark claims, as Eric Goldman notes in the article linked above, you can't trademark a descriptive phrase, and while there isn't a DMCA-style safe harbor for trademarks, courts will often effectively create a safe harbor for third parties unless there's clear evidence that they were really complicit.
