You can also find a shorter version on the USPTO website.
If you attempt to copyright a trademark, your copyright will be denied. The reverse is true as well. Copyright a slogan and you won't be able to trademark it. Disney filed for a copyright for the mouse in Steamboat Willie (when they copyrighted the work itself), but trademarked the character's name "Mickey Mouse." Recent trademarks have gone back and trademarked the character's likeness since they're used for branding. Some examples come from Disney themselves when they successfully sued Dan O'Neill for copyright infringement for using Mickey Mouse character in a parody. You can see another example by searching the USPTO for "Mickey Mouse" and you'll notice the only image of the mouse is in a logo that's expired; however, you can find several active trademarks for just the name "Mickey Mouse."
So yes, they are mutually exclusive. One is protection for a creative work, the other your brand. Disney's copyrights to Steamboat Willie and several other works will enter public domain to be sold, remixed, edited, etc. However, no one will ever be able to say they're selling "Mickey Mouse" branded t-shirts without Disney's consent. Now, you can bet that Disney will attempt to block selling of the famous cartoon since they're using it as a mark (you can find it often on recent Disney movies). http://www.youtube.com/watch?v...
