Corporate Espionage Investigations in South Dakota

01How it happens

What Corporate Espionage Looks Like in South Dakota Companies

Most trade secret cases we see are not cinematic. A sales manager downloads the customer database the week before resigning to join a competitor. An engineer emails design files to a personal account. A purchasing employee shares bid pricing with a vendor in exchange for favors. A contractor with network access copies more than the job required. In each case the information had value because competitors did not have it, and the company now needs to prove what happened quickly enough to stop the harm.

South Dakota's economy gives these cases particular shape. Manufacturers such as Daktronics and Solventum appear on the state's list of its ten largest private establishments, Sioux Falls is home to major card-services operations at Citi, Wells Fargo and First PREMIER, and agribusiness and food processing depend on proprietary processes and customer relationships. Defense-related growth around Ellsworth Air Force Base adds contractors handling sensitive information. Our corporate investigations practice covers each of these settings.

02State law

The South Dakota Uniform Trade Secrets Act in Plain Terms

South Dakota's Uniform Trade Secrets Act, SDCL chapter 37-29, defines a trade secret as information, such as a formula, method, process or compilation, that derives economic value from not being generally known or readily ascertainable by proper means and is the subject of reasonable efforts to keep it secret. Misappropriation generally means acquiring a secret by improper means, which the statute says includes theft, bribery, misrepresentation, breach of a duty to keep secrets and electronic or other espionage, or using or disclosing it without consent when the person knew or should have known it was improperly obtained.

Remedies can be significant. Under SDCL 37-29-2 a court may enjoin actual or threatened misappropriation, and under 37-29-3 damages can include actual loss and unjust enrichment or a reasonable royalty, with exemplary damages of up to twice that amount for willful and malicious misappropriation. Attorney fees may be awarded in some circumstances under 37-29-4. A claim must generally be brought within three years after the misappropriation is discovered or reasonably should have been, under 37-29-6. The federal Defend Trade Secrets Act offers a parallel federal claim, and counsel chooses the forum.

• Value from secrecy plus reasonable secrecy efforts
• Improper means includes electronic espionage
• Injunctions, damages and up to 2x exemplary damages
• Generally three years from discovery to sue

03First 48 hours

Preserving Evidence Before It Disappears

The first decisions after a suspected theft often determine whether a case can be proven. Collect and secure company laptops, phones and access badges from the departing person without wiping or reissuing them. Suspend automatic deletion of their email and files. Preserve access logs, badge records and cloud audit trails. Do not let well-meaning IT staff browse the devices, because that can alter metadata. A qualified digital forensic examiner, usually retained through counsel, should image devices before anyone reviews them.

We coordinate the non-technical side of that work: building a timeline from interviews, calendars, badge and visitor records, expense reports and public sources such as the new employer's announcements and the person's professional profiles. We identify which customers, vendors or colleagues may have been contacted and what the person told coworkers about their plans. That timeline gives the forensic examiner and counsel context for what the devices show. Our workplace theft investigations follow a similar preservation discipline for physical property.

• Secure devices without wiping or reissuing
• Suspend deletion of email and files
• Preserve badge, access and cloud logs
• Forensic imaging before anyone reviews devices

04How we investigate

Interviews, Records and Lawful Observation

Interviews with coworkers, supervisors and IT staff often reveal what logs cannot: who saw the person printing files late at night, who received an unusual request, who heard about the new job. We conduct those interviews carefully, document them accurately and avoid steps that could expose the company to retaliation or privacy claims. Represented individuals are contacted only through counsel. When the suspect is still employed, interviews are sequenced so evidence is preserved before anyone is alerted.

Records research follows the information outward. We look at new business registrations by former employees, competitor hiring patterns, trade show listings, product announcements and public filings that suggest when and how confidential information was used. Where appropriate and lawful, field observation can document meetings between a suspect and a competitor in public places, and our employee surveillance service explains how that is planned. When the evidence suggests coordination with a vendor or competitor, our corporate collusion investigations take over that thread.

05Our own limits

Investigating Espionage Without Committing It

An investigation that breaks the law can destroy the case it was meant to build. South Dakota's computer crime statute, SDCL 43-43B-1, generally makes it a crime to access a computer system without the owner's consent, with felony grades for accessing confidential data or copying information without consent, so we never log in to a suspect's personal accounts or devices. Recording a conversation without a participant's consent can be a Class 5 felony under SDCL 23A-35A-20, and installing a device in a private place to record or observe without consent is a misdemeanor under SDCL 22-21-1.

Physical limits apply too. Entering private property after notice can be criminal trespass under SDCL 22-35-6, and placing a tracker on a vehicle the company does not own creates criminal and civil exposure. Company-owned systems and devices are different: employers can generally review their own systems under their policies, though counsel should confirm the policy covers what you intend. South Dakota has no state PI license, and Delator holds its work there to the standard of its Tennessee license. Our guide to lawful investigation in South Dakota covers these boundaries in more detail.

• No access to personal accounts or devices
• No recording without a participant's consent
• No trespass or covert trackers on others' vehicles
• Company systems reviewed under company policy

06Going to court

Building the Record for a Temporary Restraining Order

Trade secret cases often move fast, with counsel seeking a temporary restraining order or preliminary injunction within days of discovery. Judges want specific facts: what information was taken, why it qualifies as a secret, what the company did to protect it, how it was taken and evidence of actual or threatened use. We organize interview summaries, timelines, documents and public-source findings into a form counsel can turn into declarations, and we stay available to testify about our work if needed.

Venue depends on the parties and claims. State cases go to circuit court in the appropriate county, such as Minnehaha County in Sioux Falls or Pennington County in Rapid City, while federal claims under the Defend Trade Secrets Act go to the U.S. District Court for the District of South Dakota, which sits in Sioux Falls, Rapid City, Pierre and Aberdeen. If the case requires serving a former employee or competitor quickly, Delator Field Services coordinates service, and businesses can be served through a registered agent under SDCL 15-6-4(d). Our South Dakota process serving page explains that work.

07Prevention

Reducing Exposure Before the Next Departure

Trade secret protection depends partly on the company's own reasonable secrecy efforts, so prevention also strengthens any future claim. A risk audit reviews who can access sensitive information, how it is marked and stored, what departing employees are asked to return and certify, and whether confidentiality agreements match current practice. South Dakota employment is generally at will under SDCL 60-4-4, which means departures can happen quickly, and an exit process that is applied consistently matters more than a perfect policy on paper. Audits start at $1,200 and are scoped in writing.

Acquisitions deserve the same attention. A buyer should confirm that a target actually protects its secrets and that its key people did not bring a former employer's information with them. Our M&A due diligence service covers that question, and a broader compliance audit can test whether confidentiality policies are followed in practice. Throughout, corporate espionage investigations in South Dakota work best when counsel, management and the investigator agree on scope at the start.

• Access and marking of sensitive information
• Consistent exit and return certification process
• Confidentiality agreements matched to practice
• Audits from $1,200, scoped in writing
