In fact, I expect you own millions of copyrights. Whether they are of any value, of course, is another story. But if a three paragraph business letter can be protected by copyright (as it was in a 1925 British case), then most if not all of the writing, illustrations or objects you have created throughout your life, are probably protected by copyright. What does this mean? It means you can stop someone else copying them, assuming of course that they would want to. They might not want to copy your childhood finger paintings or your letters to Aunt Maud, but they could well want to copy your latest research report, product design, custom-made accounting soft-ware, distribution agreement, customer database or advertising jingle. And that is where copyright can be valuable.
