I'm sure you figured this out already, but Trademarking isn't an immediate process. You have to do a search to see how many trademarks are similar to yours, and what they're being used for (in our case, it was a bunch), and then you have to decide how you're going to trademark it (clothing, CDs, etc)... Our logo and name took a year to get trademarked, and then we had to copyright all of our cartoons (all of which were wearing the trademarked logo).
