How E.I. du Pont de Nemours & Co. v. Christopher applies in South Dakota: state-specific rules, key cases, and bar exam notes for Trade Secrets / Unfair Competition.
South Dakota recognizes trade secrets as a critical category of intellectual property under the Uniform Trade Secrets Act (UTSA). The state follows the principle established in E.I. du Pont that the misappropriation of trade secrets, especially through improper means such as theft or deceptive conduct, is actionable.
In South Dakota, a trade secret is defined as any formula, pattern, compilation, program, device, method, technique, or process that derives independent economic value from not being generally known and is subject to reasonable efforts to maintain its secrecy.
The court held that a former employee's use of confidential customer lists constituted misappropriation of trade secrets.
The court ruled that breaching an NDA to utilize proprietary business information is a clear example of unfair competition under South Dakota law.
The court found that the misappropriation of trade secrets must involve some form of clandestine or improper activity.
South Dakota's approach closely mirrors the federal standard defined by the Uniform Trade Secrets Act, emphasizing the necessity for secrecy and the reasonableness of efforts to maintain it. However, South Dakota cases have focused more heavily on the context of employee-employer relationships when addressing trade secret misappropriations.
Understanding the principles from E.I. du Pont and how they apply under South Dakota law is crucial for the bar exam, particularly in the context of trade secrets and unfair competition questions.
