When negotiations break down after confidential information has already been disclosed, litigation is often resulted.
Firstly, the licensor must prove that his information is sufficiently secret, in the sense of not being duplicable without considerable time, effort or expense, to constitute an “actionable trade secret”
Also a trade secret may exist in the combination of a number of elements of information, even if each discrete element may be found in the public domain.
Secondly, the licensor must prove that his information is misappropriated.
“A misappropriation of trade secrets occurs when a person acquires or discovers a trade secret by improper means or disclosures or uses a trade secret in breach of a duty of confidentiality imposed on him by the nature of his relationship with the owner of trade secret or reposed in him by the owner in disclosing the information, and the owner of the trade secret is damaged by his improper acquisition, disclosure or use.” (American Antenna Corp. v. Amperex Elec. Corp.(1989))
“The user of another’s trade secret is liable even if he uses it with modifications or improvements upon it effected by his own efforts, so long as the substance of the process used by the actor is derived from the other’s secret” (In re Innovative Constr. Sys. Inc.(1986))
