Directions for Use

Read this instruction with CACI No. 4401, Misappropriation of Trade Secrets—Essential Factual Elements, if the plaintiff claims that the defendant’s disclosure of the information alleged to be a trade secret is a misappropriation.

If either of the first two acts constituting misappropriation by disclosure is alleged, give also CACI No. 4408, Improper Means of Acquiring Trade Secret.


Sources and Authority

“Misappropriation” Defined. Civil Code section 3426.1(b)(2).

Constructive Notice. Civil Code section 19.

“The fact that [defendant]’s postings were not of the ‘entire secret,’ and included only portions of courses, does not mean that [defendant]’s disclosures are not misappropriations. While previous partial disclosures arguably made public only those parts disclosed, [defendant]’s partial disclosures of non-public portions of the secrets may themselves be actionable because they constitute ‘disclosure … without … consent by a person who … knew or had reason to know that his … knowledge of the trade secret was … [either] derived from or through a person who had utilized improper means to acquire it [or] acquired under circumstances giving rise to a duty to maintain its secrecy or limit its use.’ ” (Religious Tech. Ctr. v. Netcom On-Line Commun. Servs. (N.D. Cal. 1995) 923 F.Supp. 1231, 1257, fn. 31.)

“Under the UTSA, simple disclosure or use may suffice to create liability. It is no longer necessary, if it ever was, to prove that the purpose to which the acquired information is put is outweighed by the interests of the trade secret holder or that use of a trade secret cannot be prohibited if it is infeasible to do so.” (Morlife, Inc. v. Perry (1997) 56 Cal.App.4th 1514, 1527 [66 Cal.Rptr.2d 731].)

“[N]othing in the UTSA requires that the defendant gain any advantage from the disclosure; it is sufficient to show ‘use’ by disclosure of a trade secret with actual or constructive knowledge that the secret was acquired under circumstances giving rise to a duty to maintain its secrecy.” (Religious Tech. Ctr., supra, 923 F.Supp. at p. 1257, fn. 31.)

“Liability under CUTSA is not dependent on the defendant’s ‘comprehension’ of the trade secret but does require ‘knowledge’ of it.” (Silvaco Data Systems v. Intel Corp. (2010) 184 Cal.App.4th 210, 229 [109 Cal.Rptr.3d 27].)

“ ‘Knowledge,’ of course, is ‘[t]he fact or condition of knowing,’ … and in this context, ‘[t]he fact of knowing a thing, state, etc. …’ (8 Oxford English Dict., supra, p. 517.) To ‘know’ a thing is to have information of that thing at one’s command, in one’s possession, subject to study, disclosure, and exploitation. To say that one ‘knows’ a fact is also to say that one possesses information of that fact. Thus, although the Restatement Third of Unfair Competition does not identify knowledge of the trade secret as an element of a trade secrets cause of action, the accompanying comments make it clear that liability presupposes the defendant’s ‘possession’ of misappropriated information.” (Silvacosupra, 184 Cal.App.4th at pp. 225–226, original italics.)

“The record contains no evidence that [defendant] ever possessed or had knowledge of any source code connected with either [software product]. So far as the record shows, [defendant] never had access to that code, could not disclose any part of it to anyone else, and had no way of using it to write or improve code of its own. [Defendant] appears to have been in substantially the same position as the customer in the pie shop who is accused of stealing the secret recipe because he bought a pie with knowledge that a rival baker had accused the seller of using the rival’s stolen recipe. The customer does not, by buying or eating the pie, gain knowledge of the recipe used to make it.” (Silvacosupra, 184 Cal.App.4th at p. 226.)

“When a competitor hires a former employee of plaintiff who is likely to disclose trade secrets, ‘[i]t is a question of fact whether the competitor had constructive notice of the plaintiff’s right in the secret.’ ” (Ralph Andrews Productions, Inc. v. Paramount Pictures Corp. (1990) 222 Cal.App.3d 676, 682–683 [271 Cal.Rptr. 797], internal citation omitted.)
