📋 What is Trade Secret Misappropriation?
Trade secret misappropriation occurs when someone acquires, discloses, or uses another's trade secret through improper means or in breach of a duty to maintain its secrecy. California protects trade secrets under the California Uniform Trade Secrets Act (CUTSA), Civil Code Sections 3426-3426.11, which provides for injunctive relief, actual damages, unjust enrichment, and exemplary damages for willful misappropriation.
Common Types of Trade Secret Theft
👥 Departing Employee Theft
Employee takes customer lists, source code, formulas, or confidential data to competitor or new business
💻 Digital Theft
Downloading files, emailing documents, USB transfers, cloud uploads of proprietary information before departure
💼 Competitor Misuse
Competitor hires employees to obtain secrets, reverse engineers beyond permitted scope, or receives stolen information
🔐 Breach of Confidence
Business partner, vendor, or contractor discloses confidential information shared under NDA
⚠ Act Immediately to Preserve Evidence
Trade secret cases are time-sensitive. Once secrets are disclosed, the damage spreads rapidly. Send a preservation letter immediately, consider seeking emergency injunctive relief (TRO), and engage a forensic IT expert to preserve evidence of data exfiltration. Delay can destroy your case and your competitive advantage.
What Qualifies as a Trade Secret?
📚 Definition Under CUTSA
▼Under Civil Code 3426.1, a "trade secret" is information that: (1) derives independent economic value from not being generally known or readily ascertainable, and (2) is subject to reasonable efforts to maintain its secrecy. This includes formulas, patterns, compilations, programs, devices, methods, techniques, or processes.
⚖ Common Examples of Trade Secrets
▼Trade secrets can include: customer and prospect lists with contact details and preferences; pricing formulas and cost structures; software source code and algorithms; manufacturing processes and formulas; business strategies and financial projections; supplier relationships and terms; marketing plans and strategies; employee compensation data; R&D data and product development information.
👥 Reasonable Secrecy Measures
▼You must prove you took "reasonable efforts" to maintain secrecy. Evidence includes: confidentiality/NDA agreements with employees and third parties; password protection and access controls; marking documents as "Confidential"; limiting access on need-to-know basis; exit interviews and equipment return protocols; employee training on confidentiality. Weak protection undermines your claim.
🔒 Document Your Secrecy Measures
Before sending a demand letter, gather evidence of all measures you took to protect the trade secret: NDAs, confidentiality policies, access logs, "Confidential" markings, training records. If your protection measures were weak, the defendant will argue the information was not truly a trade secret.
⚖ Legal Basis
California provides robust trade secret protection under CUTSA, which preempts most other claims for misappropriation of confidential business information.
Key California Statutes
Civil Code Section 3426.1 (Definitions)
Defines "trade secret" as information with independent economic value from secrecy, subject to reasonable protection efforts. Defines "misappropriation" as acquisition by improper means or disclosure/use in breach of duty.
Civil Code Section 3426.2 (Injunctive Relief)
Courts may enjoin actual or threatened misappropriation. Injunction can continue for the time necessary to eliminate commercial advantage from misappropriation. May require affirmative acts to protect the secret.
Civil Code Section 3426.3 (Damages)
Provides for actual loss plus unjust enrichment not accounted for in actual loss. In lieu of damages, court may award reasonable royalty. For willful and malicious misappropriation, court may award exemplary damages up to twice actual damages.
Civil Code Section 3426.4 (Attorney's Fees)
Court may award reasonable attorney's fees to the prevailing party if: (a) claim of misappropriation was made in bad faith, (b) motion to terminate injunction was made in bad faith, or (c) willful and malicious misappropriation exists.
Elements You Must Prove
- Trade secret exists - Information qualifies as a trade secret (economic value + secrecy measures)
- Reasonable secrecy efforts - You took reasonable steps to protect the information
- Misappropriation occurred - Defendant acquired, disclosed, or used the secret improperly
- Improper means or breach - Acquisition was through improper means OR defendant breached a duty of confidence
- Damages - You suffered actual loss, or defendant received unjust enrichment
💡 CUTSA Preemption
CUTSA preempts other civil claims based on trade secret misappropriation, including common law claims for unfair competition, breach of confidence, and unjust enrichment (to the extent based on the same conduct). This means you must bring your claim under CUTSA. However, claims for breach of contract (NDA), breach of fiduciary duty, and conversion of tangible property remain available.
Statute of Limitations
Civil Code 3426.6
3 years from when misappropriation was discovered or should have been discovered through reasonable diligence
Continuing Misappropriation
Each new act of misappropriation (disclosure or use) may restart the limitations period for that act

💡 Injunctive Relief May Be Most Valuable
Often the most valuable remedy is a preliminary injunction preventing continued use of your trade secrets. This can stop a competitor from exploiting your information while litigation proceeds. California courts can issue temporary restraining orders (TROs) within days of filing. Time is critical - seek injunctive relief immediately when misappropriation is discovered.
