I believe that if you want the protection of patent, you should disclose everything and it not suppose to be a secret. If you want to keep it as a secret, don't patent it. Isn't that is the reason behind the patent system? Inspire people to create things by providing certainty that no one will be allowed to reproduce their creations until patent expires. The only reasonable thing after that is to make the patented technology (including all the bits and pieces) a public knowledge.
