For instance, suppose there were graphical-idea patents and you wanted to draw a square. Well, you would realize that if there was a patent on a bottom edge, it would prohibit your square. You could put &ldquo;bottom edge&rdquo; on the list of all ideas implemented in your drawing. But you might not realize that somebody else with a patent on bottom corners could sue you easily also, because he could take your drawing and turn it by 45 degrees. And now your square is like this, and it has a bottom corner.
