First off, a patent on the use of XOR in a specific algorithm is hardly
a patent on the use of XOR.

Second off, this is such an obvious algorithm (around even when I was
in school, a few decades ago), that I suspect this to be "urban folk-
lore", and will continue to think so until and unless unless someone
out there can speak up and say that they have actually paid money out
of pocket for this use.
