1. This is merely a published patent application, and not an issued patent. An inventor may file a patent application that claims whatever he/she wants. An application has no legal effect until it has been examined and issued by the USPTO.

2. This particular patent application claims priority to a patent application filed on November 28, 2000. This means that any prior art must have been published before that date. It does not appear that your links contains any such prior art.

I know it is quite popular on the Internet to criticize the USPTO for its perceived "incompetence", but please make sure that you have the "competence" of understanding the basics of the US patent application process before making disparaging remarks.
