Not an IP lawyer, (those people are EXPENSIVE), It's perhaps less about the idea than it is about the process to get there. And yes the patent office does make mistakes at times. It's just expensive and hard to correct those mistakes because it generally takes a judge to do so. And I'm willing to bet this patent is valid in the EU also due reciprocity agreements and trade deals. It would take an EU judge to invalidate the patent, which would cost as much as doing so in the US.
One thing that I have learned over the years is that no patent is actually really valid until a judge bangs a gavel and says yea or nay to the patent, (I've held a couple). Until then, it pretty much just a piece of ass-wipe paper you can wavy around and hopefully scare off others that don't have the money or want to spend the money to challenge the patent.
