Not true.  As far as I know any algorithm based on computing logarithms
in a finite field are available.  Cylink is marketing a product called
SEEK which is based on this, but there are many variations of the
algorithm and I can't imagine they could have a "lock" on all of them,
since you can't patent an algorithm.
