What ales the patent system?

Right: the IPKat takes an active interest in the Great Free Beer Debate
Unusually, JIPLP is giving away an entire article as a Christmas present to the world. Says IPKat team blogger Jeremy, who edits JIPLP, "this article was just so funny, we couldn't keep it to ourselves". Accordingly you can read it now, without even waiting for Christmas, by clicking here.
The subject of this largesse is "The great free beer debate or, what ales the patent system?", by intellectual property master craftsman David Musker. Any similarity between the subject of this article and the software patent debate is purely imaginary, of course. Says the IPKat, it's brave of David to exchange the security of a career writing patents for the life of a fiction writer. Wait, says Merpel, aren't they the same thing?
