The third party re-examination procedure was brought by one Matthew Graham in 2006, and has just been decided. The claims rejected are 1-5 and 11-26, which completely eviscerates the patent. The examiner has decided that many of the claims are already covered by previous patents, and therefore have prior-art.
Just in case we are feeling smug about the madness sweeping through the other side of the Atlantic in an effort to patent anything under the sun made by man, I would suggest that people have a look at European Patents EP1678658 and EP1825357 held by Amazon. Computer implemented inventions are alive and well in Europa.
