Waitasec... I was under the impression that if you patented it, you had to reveal it. That's why RC4 isn't patented (it used to be a trade secret).
Many technologies have both patented parts and trade secret parts. Often, companies will maintain information that is in patent applications as trade secret until they are granted. I guess I should say _if_ they are granted! After a patent is granted, it is usually a good idea to also maintain some trade secrets in your products -- since trade secrets never "expire," unlike patents. If the patent isn't granted, you still have the option of treating the contents as an intellectual property under trade secret protection. dvw
