(ii) Trade secret. For purposes of paragraph (a)(4)(i)(A) of this section, a trade secret may consist of any formula, pattern, device or compilation of information that is used in one's business, and that gives one an opportunity to obtain an advantage over competitors who do not know or use it. It may be a formula for a chemical compound, a process of manufacturing, treating or preserving materials, a pattern for a machine or other device, or a list of customers. The subject of a trade secret must be secret, that is, it must not be of public knowledge or of a general knowledge in the trade or business. Novelty, in the patent law sense, is not required for a trade secret.
