This means that anyone can now freely show Steamboat Willie and use the characters of Mickey and Minnie Mouse in their own fiction. However, the current version of Mickey (with a more rounded nose and whites around his eyes) is still protected by copyright and trademark, as is the use of "Mickey Mouse" in connection with amusement parks and many other commercial ventures.
