The cited document is only an application. I can't find an associated patent, but I'm not an expert at world applications. — Eric S, Mar 03 '17 at 17:00

The document in question is an international ("PCT") application; it is not a granted patent. This application was never brought into the US as a national phase application.

There is a time limit of 30 months to bring this application into the US: https://www.uspto.gov/web/offices/pac/mpep/s1842.html

This application, filed in September 2000, is long past that deadline. In short, this application has not and will not become a granted patent in the US or anywhere else.
