The USTA defines a "trade secret" as:

• "information, including a formula, pattern, compilation, program, device, method, technique, or process that:
  • Derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and
  • Is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.
