I believe patents work by making the description impenetrable enough to make the examiner's eyes glaze over.

So they approve the patent in self-defense, and don't notice that it's just a list of trivialities.

Do you believe this based on anything in particular?

[j-g-faustus]

It's the only explanation I can find for the fact that patents like this are approved :)

(My alternative hypothesis revolves around evil conspiracies to extend property rights into the realm of generic ideas, with the aim to create a modern equivalent to the medieval landed gentry who can get rich entirely by rent-seeking[1]. All in all, I prefer the "examiners don't understand what they approve" explanation :)

I've just read all the claims and everything looks trivial once you realise that this is the basic specification for a repeating delivery system. Can you point to a single aspect of any of the claims that would reasonably be described as novel?

The OP.

Yeah, but we already discussed how the OP doesn't know what he's talking about.

I don't know whether the examiner's eyes glaze over, but mine certainly do.
