Stop Trade Secret Theft: California Business Litigation

What Counts as a Trade Secret in California?

In California, a trade secret is information that derives independent economic value from not being generally known and that is subject to reasonable efforts to keep it secret. Examples include formulas, methods, programs, customer lists, pricing, manufacturing processes, and R&D plans. If your company treats information as confidential and it provides a competitive edge because others do not know it, it may qualify as a trade secret. See California’s Uniform Trade Secrets Act (CUTSA): California Civil Code (CUTSA).

Common Signs of Trade Secret Theft

• Unusual after-hours data access or login spikes
• Mass downloads or transfers to personal devices or cloud accounts
• Device wiping, disabling security tools, or log deletion
• Sudden departures of key employees or contractors
• A competitor launching a strikingly similar product or pitch shortly after a departure
• Use of confidential documents outside authorized channels
• Refusal to return devices or materials

Immediate Steps If You Suspect Misappropriation

Act quickly and preserve evidence. Practical steps include:

• Preserve relevant email, logs, and create forensic images of devices
• Secure accounts and revoke or disable access for departing personnel
• Send preservation and demand letters where appropriate
• Review confidentiality, invention assignment, and related agreements
• Engage digital forensics to assess access, copying, and exfiltration
• Involve counsel early to prioritize remedies and avoid spoliation and business disruption

Legal Tools to Stop and Remedy Trade Secret Theft

Both California and federal law provide robust remedies:

• California (CUTSA): Courts can issue injunctions to stop use or disclosure, order the return or destruction of confidential materials, and award damages for actual loss and unjust enrichment. In willful and malicious cases, courts may award exemplary damages and reasonable attorney’s fees. See CUTSA.
• Federal (DTSA): The Defend Trade Secrets Act allows suits in federal court for misappropriation related to a product or service used in interstate or foreign commerce. Remedies include injunctions, damages, and, in extraordinary circumstances and subject to strict safeguards, ex parte civil seizure to prevent dissemination. See 18 U.S.C. § 1836 and Public Law 114-153.

How California Trade Secret Litigation Proceeds

Trade secret cases often begin with a request for emergency relief (temporary restraining order or preliminary injunction) to prevent ongoing misuse. Discovery then proceeds to identify the scope of the secrets and alleged misconduct. California requires a plaintiff to identify the trade secrets with “reasonable particularity” before obtaining discovery of the defendant’s trade secret information. See Cal. Code Civ. Proc. § 2019.210. Courts commonly enter protective orders to limit disclosure. Many cases resolve through negotiated standstill agreements or stipulated injunctions; others proceed to trial for damages and permanent relief.

Protecting Trade Secrets Before a Dispute Arises

Court remedies are strongest when a business can show reasonable measures to maintain secrecy. Strengthen your position by:

• Classifying and labeling confidential materials
• Using access controls, encryption, and least-privilege permissions
• Limiting distribution on a need-to-know basis
• Implementing clear onboarding, device use, and exit protocols
• Using NDAs and invention assignment agreements (with required notices, where applicable)
• Training employees and contractors regularly
• Auditing vendor and cloud security
• Documenting these measures to evidence reasonable efforts

Employee Mobility, Non-Competes, and California Public Policy

California strongly favors employee mobility. Non-compete agreements are generally void, subject to narrow statutory exceptions (such as certain sales of business interests and dissolution of partnerships/LLCs). See Bus. & Prof. Code § 16600 et seq.. Recent legislation reinforces non-compete restrictions and notice obligations for California workers, including § 16600.1 and § 16600.5. Businesses can and should still protect trade secrets and confidential information through narrowly tailored confidentiality and invention assignment agreements, and by pursuing remedies under CUTSA and the DTSA.

When Federal Law Applies: The DTSA

The DTSA creates a federal cause of action for trade secret misappropriation related to a product or service used in interstate or foreign commerce. Plaintiffs may seek injunctions, damages for actual loss and unjust enrichment, and, in exceptional cases, exemplary damages and attorney’s fees for willful and malicious misappropriation. See 18 U.S.C. § 1836. The DTSA also contains a whistleblower immunity provision and a related notice requirement for certain agreements; including the notice helps preserve eligibility for exemplary damages and attorney’s fees. See 18 U.S.C. § 1833(b).

Frequently Asked Questions

What if a departing employee remembers general skills and knowledge?

California law protects the use of general knowledge, skill, and experience, but not specific trade secrets. The line often turns on the specificity and secrecy of the information and whether reasonable measures protected it.

Can we stop a competitor from hiring our employees?

Generally, no. California prohibits agreements that restrain lawful professions, trades, or businesses, subject to narrow statutory exceptions. Courts can, however, enjoin use of misappropriated trade secrets and other unlawful conduct. See Bus. & Prof. Code § 16600 et seq..

Do we need to register trade secrets?

No. There is no registration system. Protection depends on secrecy and reasonable measures, enforced through statutes like CUTSA and the federal DTSA.

Are customer lists protected?

Potentially, if they derive independent economic value from not being generally known and you take reasonable steps to keep them secret. Courts consider how the list was compiled, its specificity, and the measures used to protect it.
