That is right, but does IBM ever claims that using unlicensed algotithm
is illegal or whether users should pay them license fees? I know that
IBM patents cover a large part of IT, but most of them are not used to
take legal actions agains users.

On other hand, the discussed algorithm differs from the LZW used in
TIFF. It is a bit more complicated (though, I'm not sure it produces
higher compression ratio).
