Are Customer Lists Trade Secrets?

January 20, 2025

TRADE SECRETS blank listCustomer lists can qualify as trade secrets under the right circumstances. However, not all customer lists are automatically protected under trade secret laws. Courts examine factors such as how the list was compiled, the effort required to create it, and whether reasonable steps were taken to keep it confidential. For businesses in Colorado, protecting proprietary customer information is crucial for maintaining a competitive edge.

What Makes a Customer List a Trade Secret?

Under the Colorado Uniform Trade Secrets Act (CUTSA), a trade secret includes information that is not generally known and provides a business with a competitive advantage. However, simply calling a customer list a trade secret does not make it one. Courts closely examine the nature of the list, how it was compiled, and the efforts taken to keep it confidential.

Suppose a business has invested significant time, resources, and research into developing a proprietary list that includes customer preferences, purchase history, or other valuable insights. In that case, it is more likely to qualify for protection. On the other hand, if the same information can be easily obtained from public sources, such as directories or social media, courts may rule that it does not meet the legal standard of a trade secret.

To qualify as a trade secret under CUTSA, a customer list must:

  • Independent economic value is derived from not being generally known.
  • Be subject to reasonable efforts to maintain its secrecy.

How Courts Determine Protection for Customer Lists

In Hertz v. Enterprise Rent-A-Car Co., the court ruled that a customer list was not a trade secret because the information was publicly available. Conversely, in Network Telecommunications, Inc. v. Boor-Crepeau, a Colorado court found that a client list containing specific customer preferences and service history was a trade secret due to the effort invested in developing it.

Colorado courts assess factors such as:

  • Whether the list is publicly available or compiled through unique efforts.
  • The extent of security measures taken to restrict access.
  • Whether the information provides a competitive advantage in the marketplace.

Preventing the Misuse of Customer Lists

Businesses must take proactive steps to protect their customer lists. Courts often deny trade secret status if the company fails to implement reasonable safeguards. Adequate protective measures include:

  • Non-Disclosure Agreements (NDAs): Requiring employees and business partners to sign agreements prohibiting the sharing confidential information.
  • Restricted Access: Limiting access to customer databases through password protection and internal controls.
  • Employment Contracts include non-compete and non-solicitation clauses to prevent former employees from using customer lists for competing businesses.

Implementing these protections is essential for maintaining trade secret status. At Reha Goodwin Caras LLP, we assist businesses with drafting strong agreements and enforcing trade secret protections. Explore our practice areas to learn more about how our firm can help.

Enforcing Trade Secret Protections in Colorado

If a former employee or competitor misuses a customer list, businesses may seek legal remedies under CUTSA. Remedies include:

  • Injunctions: Courts can order the immediate cessation of misappropriated trade secret use.
  • Monetary Damages: Businesses can recover losses and damages caused by unauthorized disclosure.
  • Attorney’s Fees: If misappropriation is proven, the responsible party may be required to cover legal expenses.

In a recent case, Storage Technology Corp. v. Cisco Systems, Inc., a Colorado court awarded damages to a business after determining that a former employee had unlawfully used a customer list to solicit clients for a competitor.
