Trade secret. "Trade secret" means the whole or any portion or phase of any scientific or technical information, design, process (including a manufacturing process), procedure, formula or improvement, or business plan which is secret in that it has not been published or disseminated or otherwise become a matter of general public knowledge, and which has competitive value. A trade secret is presumed to be secret when the owner thereof takes reasonable measures to prevent it from becoming available to persons other than those selected by the owner to have access thereto for limited purposes.
