Confidential information definitions establish what information is protected under NDAs. Definitions that are too broad become unenforceable—courts won't protect "all information ever disclosed." Definitions that are too narrow leave important trade secrets unprotected. The key is balancing comprehensive protection with reasonable specificity that courts will enforce and parties can actually comply with.
What 4 Elements Must Every Confidentiality Definition Include?
Confidentiality Definition Checklist
| # | Element | Purpose | Example |
|---|---|---|---|
| 1 | General definition | Establish scope | "non-public business, technical, and financial information" |
| 2 | Specific categories | Clarify what's covered | "including customer lists, pricing, source code" |
| 3 | Marking/identification | How to identify confidential info | "marked 'Confidential' or identified at disclosure" |
| 4 | Standard exclusions | Prevent over-protection | "except publicly known, independently developed..." |
Confidential Information Definition Template
**"Confidential Information"** means non-public business, technical, and financial information disclosed by Disclosing Party, including but not limited to: (a) technical information: source code, algorithms, specifications, designs, and prototypes; (b) business information: customer lists, vendor relationships, pricing, and marketing plans; (c) financial information: costs, margins, forecasts, and investment plans; and (d) any other information marked "Confidential" or identified as confidential at disclosure. **Oral Disclosures.** Information disclosed orally is Confidential Information if identified as confidential at disclosure and confirmed in writing within thirty (30) days.
The 5 Standard Exclusions (Required for Enforceability)
Courts require exclusions to prevent over-protection. Include all 5:
**Exclusions.** Confidential Information does not include information that: (a) is or becomes publicly known through no breach by Receiving Party; (b) Receiving Party possessed before disclosure, as shown by written records; (c) Receiving Party receives from a third party with legal right to disclose; (d) Receiving Party independently develops without using Confidential Information, as shown by written records; or (e) Disclosing Party authorizes for release in writing.
Exclusion Requirements
| Exclusion | Burden of Proof | Common Disputes |
|---|---|---|
| Publicly known | Receiving Party | When exactly did it become public? |
| Prior possession | Receiving Party (written records) | Timestamp and scope of prior knowledge |
| Third-party source | Receiving Party | Did third party have right to disclose? |
| Independent development | Receiving Party (written records) | Was confidential info used at all? |
Industry-Specific Definition Examples
Technology/Software NDA
Confidential Information includes: source code, object code, algorithms, APIs, data structures, technical specifications, system architecture, security protocols, development roadmaps, and beta features.
Manufacturing/Trade Secret NDA
Confidential Information includes: manufacturing processes, formulas, equipment specifications, supplier relationships, quality control procedures, and cost structures.
Business/M&A NDA
Confidential Information includes: financial statements, projections, customer contracts, employee information, pending litigation, and strategic plans.
Marking Requirements: When to Require Them
Marking Approach Options
| Approach | Language | Best For |
|---|---|---|
| Marking required | "Information marked 'Confidential'" | High-volume disclosures, clear boundaries |
| Marking helpful but not required | "...or that reasonably should be understood as confidential" | Relationship-based deals |
| No marking (all confidential) | "All information disclosed is Confidential" | Short-term, limited scope NDAs |
For oral disclosures: "Oral information must be identified as confidential at disclosure and confirmed in writing within 30 days." This prevents retroactive claims that casual conversations were confidential.
Frequently Asked Questions About Confidentiality Definitions
What makes a definition "too broad" and unenforceable?
"All information disclosed" without exclusions or marking requirements. Courts require reasonable boundaries. Include standard exclusions (public info, prior knowledge, independent development) and some identification mechanism. Definitions covering everything provide no practical protection.
Should I use specific categories or catch-all language?
Both—specific categories plus reasonable catch-all. "Including but not limited to: [specific examples]" provides clarity through examples while catch-all covers unanticipated information types. Specific-only risks gaps; catch-all-only risks overbreadth.
Do I need to address observed information?
Yes, especially for facility tours and demonstrations. Add: "...including information learned by observation of demonstrations, facility tours, and product inspections." Traditional definitions focused on documents miss information shown but not documented.
What's the difference between confidentiality and trade secret protection?
Confidentiality is contractual; trade secret protection is statutory. NDAs create contractual obligations. Trade secret laws (DTSA, state UTSA) provide independent protection for qualifying information. Your definition should cover trade secrets, but NDA protection is broader—it covers non-trade-secret confidential information too.
