An employment NDA's definition of trade secrets is legally overbroad if it includes general skills, public knowledge, or information not subject to reasonable security measures. Courts invalidate clauses that fail to distinguish between proprietary company data and an employee's own professional experience and general industry expertise.

The Legal Standard for Trade Secrets

To be legally protected, information must meet the criteria established under the Defend Trade Secrets Act (DTSA) or the Uniform Trade Secrets Act (UTSA). If an NDA defines "trade secrets" more broadly than these statutes, it is likely unenforceable.

The Three Pillars of Trade Secret Validity

  • Economic Value: The information must derive independent economic value from not being generally known or readily ascertainable by others.
  • Secrecy: The information must not be common knowledge within the industry.
  • Reasonable Measures: The employer must have taken active, documented steps to maintain the secrecy of the information.

Key takeaway: If an NDA defines trade secrets to include "all information learned during employment," it is almost certainly overbroad and unenforceable in most jurisdictions.

Action Item: Audit your NDA against the DTSA definition. If the contract lacks a "carve-out" for general knowledge and skills, it is likely too broad.

Red Flags of Overbroad Definitions

Identifying an overbroad definition requires looking for language that attempts to "capture everything." Courts view these "blanket" definitions as a restraint on trade.

Common Indicators of Overbreadth

  • Lack of Specificity: Using vague terms like "all business information" or "any data acquired during the term of employment."
  • Failure to Exclude Public Domain: The absence of language excluding information that is already public or becomes public through no fault of the employee.
  • Inclusion of General Skills: Clauses that attempt to restrict the use of "methods, techniques, or processes" that are standard practice in the industry.
  • No Time Limitation: While trade secrets can last indefinitely, defining "confidential information" as a trade secret in perpetuity without regard to its actual value is a red flag.
FeatureNarrow/Enforceable DefinitionOverbroad/Unenforceable Definition
ScopeSpecific proprietary data, algorithms, and client lists."All information learned during employment."
Public InfoExplicitly excluded.Not mentioned or included.
Employee SkillsExcluded as general knowledge.Included as "company methods."
SecurityLinked to protected assets.Applies to all internal communications.

Action Item: Review your contract for the word "all." If the definition of trade secrets begins with "all information," it is a primary candidate for a legal challenge.

Jurisdictional Nuances and Enforcement

The enforceability of an NDA is highly dependent on state law. California, for instance, has some of the strictest protections for employees, effectively nullifying overly broad non-disclosure agreements that function as de facto non-competes.

Key Jurisdictional Considerations

  1. California (BPC 16600): Courts are highly skeptical of any NDA that restricts an employee's ability to practice their profession.
  2. New York: Focuses on the "reasonableness" of the scope and the duration of the restriction.
  3. Delaware: Generally enforces contracts as written but requires clear, specific definitions of what constitutes a trade secret.

Key takeaway: In states like California, an overbroad NDA can lead to significant liability for the employer, including potential claims for unfair competition.

Action Item: Check the "Governing Law" clause in your contract. Research the specific state's stance on "overbreadth" to understand your risk profile.

How to Narrow the Definition

If you are drafting or reviewing an NDA, you must ensure the definition is "narrowly tailored." This protects the employer's legitimate interests without infringing on the employee's mobility.

Best Practices for Drafting

  • Use Enumerated Lists: Clearly define categories (e.g., "source code," "customer lists," "unreleased marketing strategies").
  • Include Exclusions: Explicitly state that "trade secrets" do not include information that is or becomes public knowledge through no fault of the employee.
  • Reference Security Measures: Define trade secrets as information that the company has "marked as confidential" or "restricted access to."

Action Item: Replace vague "all-encompassing" language with a "defined list" approach to ensure the contract remains enforceable under judicial scrutiny.
