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

How to identify an overbroad NDA definition

An employment NDA is legally overbroad if it fails to distinguish between an employer’s protectable trade secrets and an employee’s general knowledge, skills, and experience. If the definition encompasses information that is publicly available or widely known in your industry, it is likely unenforceable in most jurisdictions.

The Legal Standard for Proprietary Information

Courts evaluate the reasonableness of an NDA based on the employer's legitimate business interest. To be enforceable, the definition of "Proprietary Information" must be narrowly tailored to protect specific assets that provide the company with a competitive advantage.

Red Flags of Overbreadth

• Catch-all phrases: Language like "all information learned during employment" or "any and all data, regardless of form."
• Lack of specificity: Failure to define what constitutes a trade secret or confidential information beyond generic terms.
• Public domain inclusion: Clauses that do not explicitly exclude information that is already public or becomes public through no fault of the employee.
• Skill set capture: Definitions that imply the employee cannot use their own professional expertise or "know-how" at a future job.

Key takeaway: If the definition of proprietary information does not contain an explicit exclusion for "general knowledge and skills," it is likely overbroad and potentially unenforceable.

Comparison: Reasonable vs. Overbroad Definitions

Jurisdictional Nuances

The enforceability of these clauses varies significantly by state. For example, California (Business and Professions Code Section 16600) maintains a very strong policy against restraints on trade, making overbroad NDAs particularly vulnerable to being struck down entirely. In contrast, states like Delaware or New York may allow for "blue-penciling," where a judge rewrites the contract to make it reasonable rather than voiding it.

Steps to Assess Your Agreement

1. Identify the "Confidential Information" clause: Locate the specific section defining what you must keep secret.
2. Check for exclusions: Look for a list of items that are not confidential, such as information known to the public.
3. Evaluate the "General Knowledge" test: Ask yourself if the definition would prevent you from working for a competitor using only your own brain and professional experience.
4. Seek a carve-out: If the definition is too broad, request a written amendment that clarifies your right to use your general professional skills.

Key takeaway: Never assume a contract is standard. If the definition of proprietary information feels like it covers your entire professional identity, it is likely legally overbroad.

Protecting Your Career Mobility

Overbroad NDAs are often used as "scare tactics" to prevent employees from moving to competitors. By identifying these issues early, you can negotiate better terms or avoid signing an agreement that effectively acts as a non-compete in disguise. Always prioritize clarity over broad, sweeping language.
