SCO Announces Intellectual Property License for Linux

These guys are really starting to annoy me now! SCO Announces Intellectual Property License for Linux. They even have this made up FAQ which claims:

“Q: Does everyone who uses Linux need a SCO UNIX IP License for Linux?
A: End users running Linux 2.4 or later versions for commercial purposes need a SCO IP license.”

Regardless of the outcome of the contract dispute with IBM which has not yet been resolved in a court of law. Their claim to owning some of the IP in Linux (and Novell, the real owners of the Unix copyright say SCO only have a right to license it) is not yet proven in law. How can SCO get away with this?
