How did you even locate that? The language used in patents is so obtuse, I wouldn't even know where to look.

Also, that kind of patent REALLY makes me mad. It's pointless and stifles creation, it doesn't protect any real intellectual property. It's actually referred to as "patent trolling" and in many cases it's seen for what it is, and hard to enforce. Apple does this kind of thing a lot when they come up with the simplest function for using an ipod or ipod "A means of opening a program from within another program" or some such obvious action that is frankly necessary for operating most software.
