Usually it's ok if not all files have a license statement, since it's
reasonable to assume that they fall under the same license as the rest
of the package.  But in this case -- who knows?

Eww... this looks like a software patent.  Can you find out more about it?

I see no contradictions.  They all give the same permissions, and seem to
be compatible with the GPL in License 8.  Notice how License 2 is careful
