Wow, so few people really understand what patents are, how to read them, and how they're used.
First, no company, none, will email anyone outside their NDA circle and say "hey, we're filing a patent and we're including pictures of your stuff". That's just dumb. Inventors go to great length to hide their filings as long as possible because the invention is not protected until the patent issues. Patents are also, often, the earliest indication of future direction and therefore closely held secrets.
FutureTap retains full control of their technology. Apple did them a favor by using their interface because they have clearly indicated it as prior art.
You are required to disclose all relevant prior art in a patent-- so if what Apple is discussing is in any way similar to the Where To? app, they are required to disclose that or risk having their patent invalidated later.
If a patent is mistakenly issued to an inventor on technology that already exists, regardless of whether it has been patented, it is invalid. The patent office is not the final arbiter in these things, the courts are-- and that picture alone is a clear indication that Apple has no intention of claiming ownership if FutureTap's IP.
In fact, if a company is found to have "willfully infringed" on someone else's patented material, meaning they knew at the time that they were using patented technology, damages are tripled.
You don't draw inventions in a patent, you claim them. Everything else is context to the claims. The text and the figures are merely a way of helping the patent reviewer understand what it is you are trying to explain.
It is very common to patent enhancements to other inventors work. It is not sleazy to show a picture of Edison's light bulb and patent a better filament.
Finally, patents aside, is is common practice to adopt improvements in the state of the art. If the Where To? interface looks to be a useful one, we can expect to see it in other products, including Apple's in the same way that Where To? borrowed from Apple's click-wheel.
