As mentioned in a previous blog entry, the California Court of Appeal issued a significant trade secret decision earlier this year providing additional clarification concerning the trade secret identification disclosures which a party pursuing claims for trade secret misappropriation must make before commencing civil discovery in California state court.

The California Supreme Court subsequently denied Sylvester Stallone's and another named cross-defendant's petition for review challenging the Court of Appeal's decision.

Accordingly, the Court of Appeal decision is binding case authority.

A California statute requires that trade secrets be identified with particularity before commencing discovery relating to the trade secret in suits alleging the misappropriation of trade secrets under California’s Uniform Trade Secrets Act.

Specifically, Code of Civil Procedure § 2019.210 provides:

In any action alleging the misappropriation of a trade secret under the Uniform Trade Secrets Act (Title 5 (commencing with Section 3426) of Part 1 of Division 4 of the Civil Code), before commencing discovery relating to the trade secret, the party alleging the misappropriation shall identify the trade secret with reasonable particularity subject to any orders that may be appropriate under Section 3426.5 of the Civil Code.

In Brescia v. Angelin, 172 Cal.App.4th 133 (Mar. 17, 2009), the Court of Appeal found that Code of Civil Procedure § 2019.210 does not require in every case that a trade secret claimant explain how the alleged trade secret differs from the general knowledge of skilled persons in the field to which the secret relates. The Court found that such an explanation is required only when, given the nature of the alleged secret or the technological field in which it arises, the details provided by the claimant to identify the secret are themselves inadequate to permit the defendant to learn the boundaries of the secret and investigate defenses or to permit the court to understand the designation and fashion discovery. The Court found that the trade secret designation is to be liberally construed, and reasonable doubts regarding its adequacy are to be resolved in favor of allowing discovery to go forward.
