Case in point: when you move a mouse, the little bit of screen that was behind the mouse has to be redrawn. The obvious solution is called "backing store" - when you draw the mouse you copy what was underneath into a little store, and then when you move on you redraw from the backing store. Almost anyone faced with this problem would invent this solution. The alternatives (such as asking the application that own the screen to redraw it from scratch) are just so inefficient.
However, it is illegal to use this unless you pay a royalty to the patent holder. That is just plain BS. The law essentially says that older people have have a right to earn a living off of younger people (who because they are younger will come up the solution later). It is wrong.
I encourage you all to learn more about this topic: it is really very central to our shared freedoms.
