1. Inventions wherein the whole is more than the sum of its parts are easier to patent because they seem less obvious to patent examiners.
2. To generate these types of inventions at will, study natural and man-made synergistic phenomena.
3. Discover the laws of nature that underlie synergistic phenomena so that you can predict synergies.
4. Keep this law / these laws a trade secret.
5. Use it/them to discover one patentable invention after another – never reveal any laws of nature you are using in any invention, especially processes. Hide even your empirical rules of thumb. The USPTO is armed to reject any process patent that can be reduced to (1) A statement of rules, including laws of nature. (2) The direction to apply them.
