In California, you generally cannot stop a departing employee from competing with you — Business and Professions Code § 16600 voids most non-compete agreements. That makes trade secret law the main line of defense when key people leave with your customer data, pricing models, or technology. The California Uniform Trade Secrets Act (CUTSA), Civil Code § 3426 et seq., provides strong remedies, but only for businesses that did the protective work before the departure. Here is what qualifies, what counts as misappropriation, and what you can recover.
What qualifies as a trade secret
Under Civil Code § 3426.1, a trade secret is information — a formula, pattern, compilation, program, device, method, technique, or process — that meets two tests:
- It derives independent economic value from not being generally known to the public or to competitors who could profit from it; and
- It is the subject of reasonable efforts to maintain its secrecy.
Source code, manufacturing processes, product roadmaps, pricing and margin data, and supplier terms commonly qualify. Customer lists can qualify too, but only when they reflect real effort and contain information not readily obtainable elsewhere — a list of names you could pull from a directory generally does not. Information an employee carries in their head as general skill and experience is not a trade secret, and California courts are protective of employee mobility on this point.
"Reasonable efforts": where cases are won and lost
The second element is the one businesses fail. If you cannot show concrete secrecy measures, the claim collapses no matter how valuable the information was. Courts look for measures like:
- Confidentiality agreements with employees, contractors, and counterparties before disclosure
- Access limited to people who need it — role-based permissions, not a shared drive open to everyone
- Password protection, encryption, and marking sensitive documents confidential
- Exit procedures: collecting devices, cutting credentials promptly, and reminding departing employees of their obligations in writing
None of this requires perfection, but it requires a program you can describe under oath. An afternoon spent tightening NDAs and access controls now is worth more than months of motion practice later.
What counts as misappropriation
Civil Code § 3426.1 defines misappropriation as acquiring a trade secret when the acquirer knows or has reason to know that it was acquired through improper means — theft, bribery, misrepresentation, breach of a duty to maintain secrecy — or disclosing or using without consent a trade secret under circumstances specified in the statute, including when one knew or had reason to know that it had been acquired by improper means. The classic fact patterns: an employee downloads files to a personal drive in the final weeks before resigning; a new employer keeps using a competitor's pricing sheet its new hire brought along; a counterparty uses information received under an NDA for its own product. Note that the new employer can be liable too if it uses the information knowing or having reason to know that its disclosure or use was improper.
Remedies under CUTSA
CUTSA gives prevailing plaintiffs a serious toolkit:
- Injunctions (Civil Code § 3426.2) — courts can enjoin actual or threatened misappropriation, order materials returned or destroyed, and in exceptional circumstances condition future use on a royalty.
- Damages (Civil Code § 3426.3) — actual loss plus the defendant's unjust enrichment not accounted for in the loss calculation, or a reasonable royalty where neither is provable.
- Exemplary damages — up to twice the damages award for willful and malicious misappropriation.
- Attorney fees (Civil Code § 3426.4) — for willful and malicious misappropriation, and, running the other way, for claims brought in bad faith. That two-way fee exposure disciplines both sides.
Two procedural points matter. First, the statute of limitations is three years from when the misappropriation was or reasonably should have been discovered (Civil Code § 3426.6). Second, before commencing discovery relating to the trade secret in a CUTSA case, the plaintiff must identify its claimed trade secrets with reasonable particularity (Code of Civil Procedure § 2019.210) — vague claims stall at the gate. Businesses also have a federal option for trade secrets related to products or services used in, or intended for use in, interstate or foreign commerce: the Defend Trade Secrets Act, 18 U.S.C. § 1836, which largely parallels CUTSA and opens the federal courthouse door.
Moving fast when data walks out
Trade secret disputes reward speed. Preserve forensic evidence before devices are wiped, send preservation and cease-and-desist letters to the former employee and the new employer, and evaluate a temporary restraining order if the information is about to be used in the market. Delay undercuts both the injunction (courts ask why you waited) and the secrecy element itself. An experienced business litigation team can help move on all fronts within days, and pairing litigation readiness with well-drafted confidentiality agreements can reduce the risk of these disputes ripening.
