1. When Stolen Information Supports a Trade Secret Claim
Confidential information does not automatically qualify as a trade secret. A claimant generally must show independent economic value from secrecy and reasonable measures to preserve that secrecy.
Secrecy Measures Must Match the Information
Relevant evidence may include NDAs, access permissions, password restrictions, confidentiality markings, repository controls, employee policies, limited distribution, and offboarding procedures.
The claim should identify the actual source code, formula, customer data, pricing method, business process, technical material, or strategy at issue. Related intellectual property rights may require separate analysis.
The Trade Secret May Need to Be Defined before Discovery
For a claim governed by California procedure, the claimant generally must identify the alleged trade secret with reasonable particularity before beginning discovery relating to it.
Repository histories, access logs, device records, agreements, and internal descriptions can help define what was taken and distinguish proprietary information from general knowledge or public material.
2. Choosing Federal and State Trade Secret Claims
A business may have a federal claim under the Defend Trade Secrets Act, a state claim, or both. The available path depends on ownership, the information involved, alleged conduct, commerce nexus, and governing law.
DTSA Provides a Federal Civil Cause of Action
The DTSA permits an owner to bring a civil action when the trade secret relates to a product or service used in, or intended for use in, interstate or foreign commerce.
Misappropriation can include acquisition by improper means and certain unauthorized disclosure or use when the required knowledge is present.
State Claims Require a Separate Analysis
The California Uniform Trade Secrets Act provides a separate framework for misappropriation, injunctions, damages, and related remedies.
Federal and state claims may proceed together when their respective elements are satisfied. Contract, computer-access, fiduciary-duty, or other claims should be reviewed independently.
3. Emergency Relief and Evidence Preservation
Once proprietary information moves outside authorized systems, the key questions are where it went, who has access, whether it is being used, and what evidence remains available.
Injunctions Can Address Actual or Threatened Misappropriation
A temporary restraining order or preliminary injunction may be appropriate when evidence supports actual or threatened misuse.
Under the DTSA, an injunction cannot bar employment merely because a person knows trade secret information. Restrictions tied to employment must rest on evidence of threatened misappropriation and comply with applicable state law. A preliminary injunction strategy may turn on downloads, communications, device activity, and intended use.
Ex Parte Seizure Is Reserved for Extraordinary Circumstances
The DTSA permits ex parte seizure only when strict statutory requirements are met. It is not a routine alternative to an injunction.
The applicant must provide specific facts showing, among other requirements, that ordinary equitable relief would be inadequate and that the material may become inaccessible if notice is given.
Digital Evidence Should Be Preserved before It Changes
Relevant evidence can include email, cloud logs, source repositories, file-transfer records, returned devices, access histories, USB activity, and recipient communications.
Internal investigation should avoid altering metadata, unauthorized system access, or collection methods that create separate legal issues. Forensic preservation should maintain authenticity for potential litigation.
4. Liability and Damages for Misappropriation
A trade secret case may involve the person who first acquired the information and others who later received, disclosed, or used it. Liability depends on conduct and knowledge, not possession alone.
Recipients and Business Entities Require Individual Analysis
A former employee, contractor, competitor, or downstream recipient may present different liability questions.
An attorney should examine how the recipient obtained the information, what the recipient knew or had reason to know, and whether the material was later disclosed or used.
Damages Must Be Tied to the Economic Record
DTSA remedies can include actual loss and unjust enrichment not already included in that loss. A reasonable royalty may be available in appropriate circumstances. State law provides separate damages and royalty remedies.
Willful and malicious misappropriation can support exemplary damages of up to twice the compensatory award, and attorney fees may be available in specified circumstances.
Damages analysis may involve lost sales, avoided development costs, pricing records, market evidence, and expert analysis. Broader complex commercial litigation issues may arise in multi-party disputes
5. Frequently Asked Questions
How Long Do I Have to File a Trade Secret Misappropriation Claim?
Under the DTSA, a civil action generally must be filed within three years after the misappropriation was discovered or reasonably should have been discovered. The applicable state statute also uses a three-year discovery-based period.
Continuing misappropriation is generally treated as a single claim for limitations purposes.
Can a Customer List Qualify as a Trade Secret?
Potentially. A customer list does not become a trade secret simply because a business labels it confidential.
Protection depends on whether the information is not generally known or readily ascertainable, has economic value from secrecy, and is subject to reasonable secrecy measures. Nonpublic purchasing histories, pricing information, preferences, and specialized contacts may require fact-specific review.
6. When to Seek a Trade Secrets Attorney
Attorney involvement becomes important after an unusual download, employee departure, device-copying event, competitor solicitation, threatened disclosure, or discovery that proprietary information reached an unauthorized recipient.
A trade secrets attorney can identify the information at issue, assess ownership and secrecy measures, coordinate forensic preservation, evaluate federal and state claims, identify potential defendants, seek appropriate injunctive relief, and develop a damages theory. Related theft of intellectual property issues may require separate analysis.
The initial review should establish what was taken, who had access, where the information moved, whether use continues, what evidence remains, and which remedy fits the dispute.
