Welcome to the world of patents. The USPTO has a very specific goal: to maximize the number of patents which are granted, so long as they are valid by the USPTO's rules. Those rules do not require or even allow for a working example or model of the claimed invention(s). They also define the term "non-obvious" in a remarkably non-obvious way.
