Earlier quoted context omitted.
IBM Simon(1993/4) also had the same functionality[0]. Also, it seems that their main patent(8,086,604[1]) for this case describe a metasearch engine, something that have been around at least since the mid 90s(long before the patent was filled in 2004).

Is this kind of stuff not brought up in court? How can you possibly patent something that already existed?
The unfortunate thing is that our other laws assume that the Patent Office is able to do its job - patents are presumed to be valid unless you go through the legal hoops necessary to invalidate one. And being in the process of going through those legal hoops isn't a defense when the patent holder sues you for infringement, so there's really little benefit for you to go through them in the first place.
