How to Identify Overbroad Proprietary Information Definitions
An NDA definition is overbroad if it fails to distinguish between legitimate trade secrets and your general knowledge, skills, or experience. If the definition includes information that is public, readily ascertainable, or acquired prior to employment, it is likely unenforceable and legally overbroad.
Key takeaway: A valid definition must be narrow enough to protect the employer's competitive advantage without preventing you from working in your chosen profession after you leave.
The Anatomy of an Overbroad NDA
Most overbroad NDAs rely on "catch-all" language designed to intimidate employees. When reviewing your contract, look for these specific red flags that signal a lack of legal precision.
- Lack of Exclusions: The definition fails to explicitly exclude information that is already in the public domain or known to you prior to your start date.
- The "All-Encompassing" Trap: Phrases like "all information learned during the course of employment" are legally suspect because they capture non-confidential administrative or general industry knowledge.
- No Temporal Limit: While trade secrets can be protected indefinitely, other "confidential" information should have a reasonable expiration date (typically 2–5 years).
- Vague Categorization: The contract fails to define what constitutes a "trade secret" under the Defend Trade Secrets Act (DTSA) or state-specific Uniform Trade Secrets Act (UTSA) standards.
Action Item: Highlight any clause that does not explicitly exclude "information that becomes generally known to the public through no fault of the employee."
Comparison: Reasonable vs. Overbroad Definitions
| Feature | Reasonable Definition | Overbroad Definition |
|---|---|---|
| Scope | Specific to proprietary data/IP | Includes all knowledge/skills |
| Public Info | Explicitly excluded | Included by omission |
| Duration | Limited or tied to trade secret status | Perpetual for all data |
| Prior Knowledge | Excluded | Not mentioned |
Legal Standards for Enforceability
Courts apply a "reasonableness" test to determine if an NDA is enforceable. In jurisdictions like California, the standard is exceptionally high, and broad NDAs are often struck down entirely under Business and Professions Code Section 16600.
The "General Knowledge" Doctrine
You have a fundamental right to your own "skill, knowledge, and experience." An NDA cannot legally prevent you from using the general professional expertise you developed while working for a company. If a definition of proprietary information is so broad that it effectively prevents you from working for a competitor by claiming your "experience" is their "proprietary information," it is overbroad.
The Requirement of Independent Economic Value
Under the DTSA, information must derive independent economic value from not being generally known to qualify as a trade secret. If your NDA defines "proprietary information" to include things like internal meeting schedules or standard office procedures, it fails this test.
Action Item: Check if your contract defines "Confidential Information" as anything that provides a "competitive advantage." If it does, ensure there is a carve-out for your general professional skills.
How to Evaluate Your NDA Step-by-Step
- Identify the Definition Section: Locate the "Definitions" or "Confidential Information" clause.
- Check for Exclusions: Look for a list of items that are NOT confidential (e.g., public info, prior knowledge).
- Assess the "General Knowledge" Clause: Ensure there is language protecting your right to use your general skills.
- Verify the Duration: Determine if the confidentiality obligation is perpetual or time-bound.
- Consult Local Law: Check if your state has specific statutes (like California or Oklahoma) that limit the scope of restrictive covenants.
Key takeaway: If your NDA lacks a "General Knowledge" carve-out, you are at higher risk of being sued for simply performing your job duties at a new company.
