Are perpetual confidentiality clauses enforceable for tech workers in South Dakota?

Perpetual confidentiality clauses are generally unenforceable in South Dakota if they are overly broad or lack a legitimate business justification. South Dakota courts apply a 'reasonableness' test, requiring that restrictions be no broader than necessary to protect trade secrets. If a clause prevents a tech worker from using general industry knowledge, it will likely be struck down.

The Legal Standard for NDAs in South Dakota

South Dakota law, specifically under SDCL 53-9-11, governs the enforceability of restrictive covenants. While confidentiality agreements are distinct from non-compete agreements, courts often analyze them through a similar lens of 'reasonableness.' For a tech worker, a perpetual clause is inherently suspect because the shelf-life of technical information—such as specific coding languages, frameworks, or software architecture—is often short.

Criteria for Enforceability

• Legitimate Business Interest: The employer must prove the information being protected is a genuine trade secret or proprietary data, not merely general skill or knowledge.
• Reasonable Scope: The restriction must be limited to specific, identifiable confidential information.
• No Undue Hardship: The clause cannot effectively prevent the employee from working in their chosen field or utilizing their professional expertise.
• Public Policy: The agreement must not violate the state's interest in fostering a competitive labor market.

Key takeaway: If your NDA prevents you from using 'general knowledge, skill, or experience' acquired during your employment, it is likely unenforceable under South Dakota law, regardless of whether it is labeled as 'perpetual.'

Action Item: Review your contract to see if it distinguishes between 'Trade Secrets' and 'General Knowledge.' If it does not, the clause is likely overbroad.

Why 'Perpetual' is a Red Flag in Tech

In the tech industry, the half-life of information is rapid. A perpetual confidentiality clause implies that information remains sensitive forever. However, if the information is publicly available, reverse-engineered, or obsolete, the employer no longer has a legitimate interest in keeping it secret. South Dakota courts are increasingly skeptical of 'forever' clauses that serve only to stifle competition rather than protect intellectual property.

Common Red Flags in Tech Contracts

• Overly Broad Definitions: Defining 'Confidential Information' to include everything discussed in meetings or emails.
• Lack of Exclusions: Failing to exclude information that is public knowledge or independently developed.
• Vague Scope: Failing to specify which projects or technologies are covered.
• No Sunset Provision: Demanding secrecy for information that will be obsolete within 12 to 24 months.

Action Item: If you are presented with a perpetual NDA, request a 'sunset clause' that limits the confidentiality obligation to 2 or 3 years post-employment, or until the information enters the public domain.

Steps to Evaluate Your Contract

1. Identify the Protected Information: Does the contract specifically define what is confidential, or is it a catch-all phrase?
2. Assess the 'Trade Secret' Status: Is the information actually a trade secret under the South Dakota Uniform Trade Secrets Act (SDCL 37-29)?
3. Check for Severability: Does your contract contain a 'severability clause' that allows a court to strike out the unreasonable parts while keeping the rest of the agreement intact?
4. Consult Counsel: If the contract is a condition of employment, have a local attorney review the specific language to determine if it crosses the line into an illegal restraint of trade.

Key takeaway: A contract that is too broad to be enforced in its entirety may be entirely voided by a court, depending on the specific drafting of the severability clause.

Action Item: Before signing, ask HR or legal counsel for a list of the specific 'Trade Secrets' the company intends to protect. If they cannot provide one, the NDA is likely a boilerplate document that may not hold up in court.
