How to tell if an employment NDA definition of proprietary information is legally overbroad?

How to Identify an Overbroad NDA Definition

An employment NDA definition is legally overbroad if it fails to distinguish between an employer's legitimate trade secrets and an employee's general knowledge, skills, or experience. If the definition captures information that is publicly available or commonly known in the industry, it is likely unenforceable.

Key takeaway: If an NDA prevents you from using your general professional expertise or knowledge acquired prior to employment, it is likely an illegal restraint of trade rather than a valid protection of proprietary information.

Red Flags in Proprietary Information Clauses

When reviewing an NDA, look for language that attempts to claim ownership over everything you touch. These red flags often signal that the employer is overreaching:

• Lack of Exclusions: The definition fails to exclude information that is already in the public domain or independently developed.
• Catch-all Language: Phrases like "all information learned during the course of employment" or "any and all data, regardless of form."
• Subjectivity: Definitions that rely on the employer's "sole discretion" to determine what constitutes proprietary information.
• Temporal Ambiguity: Clauses that do not specify a duration for confidentiality, effectively creating a permanent restriction on information that may lose its value over time.

Action Item: Scan your contract for the phrase "all information." If it appears without a qualifying list of specific trade secrets, it is a primary candidate for revision.

Comparison: Reasonable vs. Overbroad Definitions

Jurisdictional Standards and Enforceability

The legality of an NDA is highly dependent on your state. California, for example, maintains a strict stance under Business and Professions Code Section 16600, which voids contracts that restrain anyone from engaging in a lawful profession. In states like New York or Delaware, courts apply a "reasonableness" test.

The Reasonableness Test

Courts typically evaluate whether the definition is:

1. Necessary: Is the information actually a trade secret that provides a competitive advantage?
2. Limited: Does it allow the employee to use their general skills?
3. Specific: Is the definition narrow enough that the employee knows exactly what they cannot disclose?

Key takeaway: If a court finds a definition overbroad, it may either "blue-pencil" (rewrite) the contract to make it reasonable or strike the entire provision, leaving the employer with no protection at all.

Steps to Evaluate Your NDA

If you are concerned about an NDA you have been asked to sign, follow this systematic review process:

1. Identify the "Proprietary Information" section: Locate the specific definition clause, usually found in the first few pages.
2. Check for "General Knowledge" carve-outs: Ensure the text explicitly states that the employee's general skills and experience are not proprietary.
3. Verify Public Domain exclusions: Confirm that information that becomes public through no fault of the employee is excluded.
4. Compare against industry standards: Ask if the definition covers information that is standard knowledge for your specific role.

Action Item: If you find an overbroad definition, request a "carve-out" clause that specifically protects your right to use your general professional skills in future employment.

Conclusion

Protecting proprietary information is a legitimate business interest, but it cannot come at the cost of an employee's right to earn a living. By identifying vague, catch-all, or overly restrictive definitions, you can better protect your career mobility and legal standing.
