Patent dreams

Had a very strange dream about patented things. I'm not entirely sure if it was actually a dream, or something I'm remembering from reading somewhere though.

So there I am having one of my 'fly on the wall' type dreams watching some guy talk to someone about computer related patents. He's talking about one in particular, a patent for some kind of network router that he tried to build from the plans in the patent application. For some reason he couldn't get it to work at all, so he was wondering what other kinds of ridiculous things had been granted patents, but didn't work at all.

Then I woke up.

Very strange.
