I don't think it is patented anymore. It was invented in 1977 which was 19
years ago. The patent therfore expired a couple years ago. It is now
public domain. However, I am rethinking and I thought that for ZCompress
or whatever the name will be, a arithmetic compression algorithm would work
best. Although slow, it provides for excellent compression, which is the
main reason for the compressor.
