Yup. I have heard that one very large Australian company was visited by RSA's
legal people a few years back and told they needed a patent for RSA. They
said, get lost, and they did. Mind you, that same company now has an RSA
licence, but I belive this was so they could sell their software/hardware into
the USA.

While I agree that patents are often a good thing, especially when there is a
high R&D cost, like drugs, my concernt with software patents, specifically
crypto related ones is that the acceptance of a cipher can be greatly reduced
by a patent. Why study a cipher if some company is going to get direct $$
advantage from reports of its resistance to attack? RSAs is doing things
differntly with RC5 compaired to RC4 :-). Hopefully AES will save the day
before RC5 become too popular. It has already wormed its way into S/MIME...
TLS was delayed for quite some time due to this type of thing.

Anyway, I'm just having another grumble....
