How do I identify an overly broad NDA definition?

Look for vague, catch-all language like 'all information disclosed' without specific exclusions for public knowledge, independent development, or general industry skills.

Why is a broad definition dangerous?

It creates an impossible compliance burden, restricts your ability to work in your field, and can lead to breach of contract claims for using common knowledge.

A TermScore is an AI-generated risk rating from 0 to 100 that evaluates the fairness and risk level of any legal document. A score of 86-100 means the contract is highly favorable, while 0-30 indicates dangerous terms you should walk away from.

What types of documents can TermScore analyze?

How to tell if an NDA's definition of proprietary information is legally overly broad

How to Identify an Overly Broad NDA Definition

An NDA's definition of proprietary information is legally overly broad if it fails to distinguish between trade secrets and general industry knowledge. If the clause captures all information disclosed without specific exclusions for public domain data, independently developed materials, or general skill sets, it is likely unenforceable and poses a significant litigation risk.

The Red Flags of Overly Broad Definitions

When reviewing a Non-Disclosure Agreement, look for language that attempts to capture everything under the sun. Courts generally disfavor "catch-all" provisions that do not provide the receiving party with fair notice of what is actually protected.

Lack of Marking Requirements: If the contract does not require written information to be marked as "Confidential" or "Proprietary," you are forced to guess what is protected.
Absence of Exclusions: A robust NDA must explicitly exclude information that is already public, independently developed, or received from a third party without a breach of duty.
Infinite Scope: Definitions that include "all information, whether oral, written, or observed" without context are often deemed unreasonable.
Lack of Subject Matter Limitation: If the definition covers everything discussed during a business relationship rather than specific project-related data, it is too broad.

Key takeaway: If you cannot clearly identify what information you are prohibited from using, the definition is too broad. Demand a "carve-out" for general knowledge and skills acquired during the engagement.

Comparison: Reasonable vs. Overly Broad Definitions

Feature	Reasonable Definition	Overly Broad Definition
Scope	Specific to project data	"Any and all information"
Exclusions	Includes public domain/general skills	None
Marking	Requires "Confidential" label	No requirement
Duration	Limited to 2-5 years	Perpetual

How to Negotiate a Narrower Definition

If you encounter an overly broad definition, you must push back to protect your operational freedom. Follow these steps to refine the language:

Request a "Marking" Clause: Require that all physical documents be stamped "Confidential" and that oral disclosures be summarized in writing within 30 days.
Insert Standard Exclusions: Ensure the definition excludes information that is or becomes public through no fault of your own.
Limit to Business Purpose: Restrict the definition to information "disclosed in connection with the specific project" rather than the entire business relationship.
Carve out General Skills: Explicitly state that the NDA does not prevent the use of general knowledge, skills, or experience gained during the term of the agreement.

The Legal Consequences of Broad Definitions

In many jurisdictions, including California (under Business and Professions Code Section 16600), courts are increasingly hostile toward NDAs that effectively function as non-compete agreements. If a definition of "proprietary information" is so broad that it prevents an employee or contractor from using their general professional knowledge, a court may strike the entire provision or the entire agreement as an illegal restraint of trade.

Jurisdictional Nuances

While New York and Delaware courts may allow for broader definitions in sophisticated commercial transactions, they still require "reasonableness." In the context of employment, however, the threshold for what is considered "overly broad" is significantly lower. Always check if your jurisdiction requires the definition to be "narrowly tailored" to protect legitimate trade secrets.

Key takeaway: An overly broad definition is not just a nuisance; it is a liability. It can be used as a pretext for litigation to stifle competition or punish former partners.

Practical Action Items

Audit your existing NDAs: Review your current portfolio for the absence of standard exclusions.
Standardize your "Carve-outs": Create a "safe harbor" clause that you insert into every NDA you review.
