What NDAs Actually Protect — and What They Don't
A non-disclosure agreement (NDA) is a contract that obligates one or both parties to keep specified information confidential and to use it only for defined purposes. NDAs are the foundational instrument of commercial trust — they enable M&A due diligence, technology licensing, employment relationships, and partnership negotiations by giving the disclosing party a contractual remedy if the recipient misuses what they learn.
What they protect: proprietary business information, technical specifications, financial projections, customer lists, product roadmaps, source code, formulas, and any other information the parties agree to treat as confidential. What they do not protect: information that is already public, that the recipient independently developed, or that they lawfully received from a third party. These standard exclusions are not optional carve-outs — they reflect a fundamental legal principle that secrecy must be real, not just declared.

Trade Secret Definition Under DTSA § 1839(3)
The Defend Trade Secrets Act, 18 U.S.C. § 1839(3), provides the controlling federal definition. A trade secret is any financial, business, scientific, technical, economic, or engineering information — including formulas, patterns, compilations, programs, devices, methods, techniques, or processes — that: (a) the owner has taken reasonable measures to keep secret, and (b) derives independent economic value from not being generally known or readily ascertainable. Both prongs are mandatory.
| Element | What Courts Look For | Common Failure Mode |
|---|---|---|
| Reasonable secrecy measures | Password protection, NDAs with employees, access controls, physical security, confidentiality training | Disclosing to dozens of third parties without NDAs, no internal access restrictions |
| Independent economic value | Competitive advantage, cost to develop, market value if disclosed | Information is general industry knowledge with no specific economic benefit from secrecy |
| Not generally known | Not in public literature, patent filings, or freely available to competitors | Information appears in published papers, public filings, or is standard industry practice |
The distinction between trade secrets and general confidential information matters enormously: trade secrets enjoy statutory protection under the DTSA and the Uniform Trade Secrets Act (adopted in 48 states) regardless of whether an NDA exists. General confidential information is protected only by contract. An NDA typically covers both — but the strength and duration of protection differs significantly between categories.

Check My NDA Free →Mutual vs. One-Way NDA — Structure and Risk
The structural choice between a mutual and one-way NDA determines which party bears legal obligations — and who faces liability for breach. A one-way NDA is appropriate when only one party discloses: an inventor sharing a concept with a manufacturer, or a company disclosing financials to a potential acquirer. A mutual NDA is appropriate when information flows in both directions: joint development discussions, partnership negotiations, or any situation where both parties will share proprietary data.
One-Way (Unilateral) NDA
Only the receiving party bears confidentiality obligations. Appropriate when the disclosure relationship is genuinely asymmetric. If you are the disclosing party in a one-way NDA, verify that your counterpart cannot technically share your information under the "permitted disclosure to affiliates" exception. If you are the receiving party, push for mutual structure whenever two-way exchange is likely.
Mutual (Bilateral) NDA
Both parties bear confidentiality obligations. Standard for M&A due diligence, joint ventures, licensing discussions, and technology partnerships. Does not automatically mean equal practical exposure — a startup sharing its core algorithm with a Fortune 500 partner has asymmetric risk even in a mutual structure. Consider adding separate carve-outs for information categories where the exposure is genuinely unequal.
Watch Out
Non-mutual NDAs in employment contexts raise additional concerns: if an employer presents a unilateral NDA requiring the employee to protect company information with no reciprocal protection for the employee's own prior inventions and knowledge, the employee should attach an invention assignment carve-out schedule listing prior inventions they wish to exclude from the agreement's scope.
What to Do
Negotiating the Confidential Information Definition
The definition of “Confidential Information” is the most important clause in any NDA. Too broad and the NDA becomes a trap — any casual business discussion becomes grounds for a breach claim. Too narrow and genuinely proprietary information falls through the gaps. The negotiation goal is a definition that captures what is actually sensitive and excludes what is legitimately public or general industry knowledge.
Common Definition Approaches
| Approach | What It Covers | Risk Level | When Appropriate |
|---|---|---|---|
| Catch-all ("any and all information") | Everything disclosed, regardless of sensitivity or marking | 🔴 High — overbroad, may be void for vagueness | Never acceptable as a recipient |
| Marked-only (must be labeled "Confidential") | Only information expressly marked at time of disclosure | 🟡 Elevated — oral information often unprotected | Acceptable for commodity vendor relationships |
| Marked + follow-up summary (30-day window) | Marked information plus oral disclosures reduced to writing within 30 days | 🟢 Balanced — market standard | Most commercial NDAs, partnerships, licensing |
| Category-specific (list of defined categories) | Only specified types: customer lists, pricing, source code, formulas, etc. | 🟢 Preferred — narrowly tailored | Technology NDAs, M&A NDAs, employment NDAs |
Red Flag
The permitted use provision works in tandem with the definition: even if information qualifies as Confidential Information, the recipient should be permitted to use it for the specific purpose of the parties' discussion (e.g., “evaluating a potential business relationship”). Permitted use language that says only “the purpose disclosed above” without identifying the purpose is a drafting error that can make the recipient's ordinary internal review activities technically non-compliant.
5 Standard Exclusions Every NDA Must Have
The following five exclusions reflect settled law and commercial practice. Any NDA that omits them is one-sided. Courts have read some of these exclusions into NDAs as implied terms, but relying on judicial gap-filling is far riskier than explicit drafting. Demand all five before signing.
Prior Possession
Information already in the recipient's possession before the disclosure. Key requirement: the recipient must be able to document prior possession with contemporaneous records. A mere assertion of prior knowledge is insufficient — the burden of proof falls on the party claiming the exclusion.
Public Domain
Information that is or becomes publicly available through no fault of the recipient. Note: the information must become public through a source other than the recipient's own breach. If the disclosing party itself publishes the information (e.g., in a patent filing, press release, or SEC disclosure), the exclusion applies immediately. The recipient's NDA obligation terminates on publication.
Independent Development
Information independently developed by the recipient without use of or reference to the disclosed information. This exclusion is frequently litigated and difficult to prove. Require the recipient to maintain detailed development logs contemporaneously — a poorly documented independent development claim is almost always lost in court. Consider adding a "clean room" protocol requirement for high-risk technology disclosures.
Legitimate Third-Party Receipt
Information received from a third party who is not under a confidentiality obligation to the disclosing party with respect to that information. The exclusion applies only if the third party is legitimately free to disclose — receiving stolen trade secrets from a leaking employee does not trigger this carve-out. The recipient must conduct reasonable due diligence on the source of the information.
Compelled Disclosure
Disclosure required by applicable law, court order, or regulatory authority. Standard practice: the recipient must give the disclosing party prompt written notice (to the extent legally permitted) and cooperate in seeking a protective order. The recipient should disclose only the minimum required and should use commercially reasonable efforts to obtain confidential treatment for any disclosed information. This provision protects the recipient who receives a government subpoena — they cannot be held liable for lawful cooperation with legal process.

Check My NDA Free →Residuals Clauses and Inevitable Disclosure
Two NDA provisions that operate as major exclusions from confidentiality obligations — and that are frequently misunderstood by non-lawyer signatories — are the residuals clause and the inevitable disclosure doctrine.
Residuals Clauses
A residuals clause states that the recipient may use information retained in the “unaided memory” of employees who had access to confidential information — for any purpose, including product development — even if that information was technically within the NDA's scope. The practical effect: once an engineer reviews your proprietary architecture and the NDA expires, they are free to build competing products using everything they can remember.
Red Flag
If deletion is not achievable, negotiate these limitations: (a) residuals apply only after NDA expiration, not during the term; (b) residuals are limited to general skills and knowledge, not specific formulas, algorithms, or business plans; and (c) employees who accessed the disclosed information may not work on directly competing products for 12 months post-disclosure.
Inevitable Disclosure Doctrine
The inevitable disclosure doctrine allows a court to enjoin a former employee from working for a competitor even without proof of actual misappropriation — the theory being that the employee cannot perform their new role without inevitably using or disclosing their former employer's trade secrets. This doctrine creates NDA risk for employees who move between competitors: the NDA from the prior employer, combined with the doctrine, can effectively function as an undisclosed non-compete.
| State | Inevitable Disclosure | Notes |
|---|---|---|
| IL | Recognized | PepsiCo v. Redmond — leading case; applied to senior executives with access to strategic plans |
| CA | Rejected | Bus. & Prof. Code § 16600 forbids restraining employment; actual/threatened misappropriation required |
| NY | Limited | Applied cautiously; requires showing employee cannot compartmentalize knowledge |
| TX | Recognized cautiously | Must show specific trade secrets at risk, not general knowledge |
| MA | Recognized | Applied to technical trade secrets; less certain for general business information |
Key Principle
DTSA § 1833(b) Whistleblower Immunity — Required Notice
The Defend Trade Secrets Act, 18 U.S.C. § 1833(b), provides that an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (1) in confidence to a federal, state, or local government official or attorney solely for the purpose of reporting or investigating a suspected legal violation; or (2) in a complaint or other document filed in a lawsuit if filed under seal.
The statute imposes a mandatory disclosure obligation on employers: any NDA or employment agreement that governs trade secrets or confidential information must include a notice of this immunity. Failure to provide the notice has an automatic consequence — the employer forfeits the right to seek exemplary damages (up to 2x actual damages) and attorney fees in any subsequent DTSA claim against the employee. These are significant remedies that most employers will want available.

Industry-Specific NDA Rules — Tech, M&A, Employment, VC, Healthcare
NDA negotiation norms vary significantly by industry. What is standard in a Silicon Valley technology deal may be unusual in M&A practice, and employment NDA terms that are acceptable in New York may be void in California. The five industry contexts below cover the most common NDA negotiations.
Technology & Software
- Residuals clauses are standard — push to delete or limit to post-term, non-specific skills
- Source code NDAs should include a category-specific definition, not a catch-all
- API access NDAs often include non-reverse-engineering obligations — verify enforceability under DMCA § 1201
- Open source combination risks: NDA cannot protect code that must be disclosed under GPL or LGPL license obligations
M&A Due Diligence
- Standstill provisions often embedded in M&A NDAs — these restrict the target from selling to third parties during the exclusivity window
- Non-solicitation of employees is standard in M&A NDAs and survives deal failure; review scope carefully
- Permitted disclosure to advisors (counsel, bankers, consultants) must be limited by a need-to-know standard
- Return or destruction of due diligence materials should be triggered by deal termination, with certification requirement
Employment
- Employee NDAs must include DTSA § 1833(b) whistleblower immunity notice or exemplary damages are forfeited
- California employees: any provision restricting use of general skills learned on the job is likely void under § 16600
- Invention assignment clauses frequently embedded in employment NDAs — carve out prior inventions in writing before signing
- Garden leave (paid non-compete) provisions are increasingly paired with NDAs to provide consideration for post-employment restrictions
Venture Capital & Startups
- Most reputable VCs will not sign NDAs before initial meetings — this is industry norm, not a red flag
- Post-term sheets: NDA for due diligence phase is appropriate and typically mutual
- Portfolio company information shared across a fund's portfolio management team should be restricted by express permitted-use limitations
- Founder-to-VC NDAs should include a sunset provision — 3 years is standard for early-stage deals
Healthcare & Life Sciences
- HIPAA-covered information requires a Business Associate Agreement (BAA) in addition to or instead of a standard NDA
- Clinical trial data NDAs must address regulatory disclosure obligations — FDA reporting requirements may mandate disclosure notwithstanding the NDA
- Drug formulation and device design NDAs routinely survive 10+ years due to long development cycles and patent term considerations
- Research collaboration NDAs should address publication rights — most academic institutions require a publication right within 90–180 days of notice

Check My NDA Free →6 Landmark Cases Every Party Should Know
Waymo LLC v. Uber Technologies, Inc.
N.D. Cal. · 2018 · No. 3:17-cv-00939 (N.D. Cal., settled Feb. 2018)
Impact: The defining modern trade secret case, illustrating the DTSA's power and the massive damages available in high-profile misappropriation suits. Waymo established that courts will grant expedited discovery and early injunctive relief in DTSA cases where there is strong evidence of systematic misappropriation before departure. The case accelerated adoption of data loss prevention (DLP) technology as a standard trade secret protection measure. Any NDA covering technology used by employees with access to core product data should be paired with DLP protocols and offboarding procedures that include forensic review.
PepsiCo, Inc. v. Redmond
7th Cir. · 1995 · 54 F.3d 1262 (7th Cir. 1995)
Impact: The foundational case establishing the inevitable disclosure doctrine under federal law. Its logic has been adopted in Illinois, New York, Texas, Massachusetts, and other jurisdictions — and rejected expressly by California. Any NDA governed by Illinois law used with senior employees who have access to strategic plans, pricing, or competitive intelligence carries inevitable-disclosure risk that effectively functions as an implied non-compete. This case is why sophisticated employees negotiating Illinois-governed NDAs should insist on explicit language stating that the NDA does not create any post-employment restriction beyond the DTSA and UTSA.
Shellenberger v. Tanner
Ga. App. · 1976 · 138 Ga.App. 399 (1976)
Impact: Illustrates that courts will not enforce overbroad NDA definitions that would prevent employees from using general industry knowledge and skills gained during employment. The ruling predates modern DTSA analysis but captures a principle now reflected in California § 16600, the DTSA's trade secret definition, and the employment carve-outs in most state UTSA adoptions: only information that is genuinely secret, with independent economic value, can be restricted post-employment. NDAs that sweep in all "information acquired during employment" without a secrecy limitation are systematically overbroad.
DVD Copy Control Ass'n v. Bunner
Cal. Supreme Court · 2004 · 31 Cal.4th 864 (2004)
Impact: Critical for NDA enforceability when information has been publicly disclosed, even if without the disclosing party's authorization. Once information becomes generally known — regardless of how — its trade secret status is destroyed and NDA obligations over that specific information terminate under the public domain exclusion. Disclosing parties who fail to take immediate action to contain unauthorized disclosures may find that delay destroys the protection they sought to enforce. This case also highlights the First Amendment dimension of trade secret injunctions affecting speech.
Learning Curve Int'l v. Cardinal Industries, Inc.
N.D. Ill. · 2003 · No. 01-C-5539 (N.D. Ill. 2003)
Impact: Clarifies the enforceability standard for liquidated damages in NDA breach cases. Actual NDA damages — lost profits from a competitor learning your strategy, reduced negotiating leverage, cost of developing alternative trade secrets — are notoriously difficult to calculate, making liquidated damages clauses commercially attractive. Courts uphold them where: (a) damages were difficult to estimate at contracting; (b) the amount is not disproportionate to likely actual harm; and (c) the clause functions as compensation, not punishment. Both disclosing parties (who want certainty) and recipients (who want proportionality) should pay close attention to these provisions.
Earthbound Corp. v. MiTek USA, Inc.
W.D. Wash. · 2016 · No. C15-1165 (W.D. Wash. 2016)
Impact: Demonstrates that courts look at NDA consideration and mutuality holistically. A one-way NDA with an overbroad definition may fail for lack of consideration if the obligation imposed on the recipient is so expansive that it restricts the recipient from ordinary business activities rather than genuinely secret information. This case supports the negotiating position that receiving parties have a right to demand narrower definitions as a precondition to giving enforceable confidentiality promises.

Negotiation Matrix — 8 Clause Scenarios
Use this matrix when reviewing an NDA. Match the language you see to the scenario, assess the risk level, and apply the counter-offer strategy before responding to the other side.
| Clause Language / Structure | Risk Level | Your Leverage | Counter-Offer | Walk-Away Signal |
|---|---|---|---|---|
| Catch-all confidential information definition — "any and all information disclosed by either party" | 🔴 Critical | High — this is objectively overbroad | Replace with category-specific definition or marked-plus-oral-summary approach; exclude information in the public domain as of the date of disclosure | Disclosing party refuses any narrowing and demands catch-all with no exclusions |
| Residuals clause permitting unaided memory use for any purpose, including product development | 🔴 High | Medium — standard in big tech; harder to delete | Limit to post-NDA-term; restrict to general skills, not specific algorithms or business plans; add 12-month cooling-off for employees who accessed core IP | Other party refuses any limitation on residuals and insists on unlimited concurrent use |
| Non-mutual one-way NDA when discussions will clearly involve two-way information exchange | 🔴 High | High — structurally mismatched | Request mutual NDA as precondition to any disclosure; if other party insists on one-way, add a side letter or email confirming any information you share is also confidential | Other party refuses mutual structure and insists on disclosing your information informally |
| Perpetual term with no sunset provision | 🟡 Elevated | High — perpetual NDAs increasingly disfavored | Propose a defined term (3–5 yrs for general confidential information) with a carve-out providing that trade secret obligations continue as long as information legally qualifies as a trade secret | Other party refuses any term limitation and provides no trade-secret carve-out mechanism |
| Permitted use defined as "evaluating a potential relationship" without specifying the relationship | 🟡 Elevated | High — vague purpose definitions create enforcement risk for both sides | Define the specific purpose: "evaluating a potential [software development / licensing / acquisition / partnership] between the parties" | No walk-away — fix this before signing regardless of leverage |
| Missing compelled disclosure carve-out — no right to comply with government subpoenas or court orders | 🟡 Elevated | High — this is a standard protective term | Add standard compelled disclosure carve-out with notice and cooperation obligations; specify notice may be omitted if legally prohibited | No walk-away — this is a technical fix both sides should want |
| Missing DTSA § 1833(b) whistleblower immunity notice in an employment or consulting NDA | 🟡 Elevated | High — required by statute | Add the verbatim DTSA notice or a cross-reference to a whistleblower policy containing the notice; applicable to any NDA executed after May 11, 2016 | No walk-away — required notice; employer loses exemplary damages and attorney fees without it |
| Mutual, category-specific NDA with 3-year term, standard exclusions, compelled-disclosure carve-out, and DTSA notice | 🟢 Acceptable | Strong — commercially balanced baseline | Confirm governing law matches the primary jurisdiction; verify permitted use is specific; ensure return/destruction obligation has a reasonable backup-system carve-out | No walk-away signal; negotiate residuals and term refinements only |
8 Common Mistakes with Dollar Costs
Signing a catch-all confidential information definition
$50,000–$500,000+ in litigation exposureAn NDA that covers "any and all information" can support a breach claim based on casual business conversations, emails referencing a partnership, or LinkedIn posts mentioning a project — none of which the parties understood to be confidential. Defense costs alone in NDA breach litigation typically run $50,000–$200,000 before trial. Push for a category-specific or marked-plus-summary approach that creates a clear, documented universe of protected information.
Missing the DTSA § 1833(b) whistleblower immunity notice in employment NDAs
Loss of exemplary damages (up to 2x actual) and attorney fees in DTSA suitsEmployers who omit the mandatory DTSA whistleblower notice from employee NDAs forfeit the right to seek exemplary damages and attorney fees in subsequent DTSA claims — even for willful and malicious misappropriation. In a high-stakes trade secret case where actual damages are $5 million, this omission could cost $10 million in forfeited exemplary damages. The notice is two sentences. There is no excuse for omitting it.
Accepting a residuals clause without limitation
Core IP effectively unprotectable by departing employeesAn unlimited residuals clause permits a departing engineer who reviewed your proprietary source code, training data, or product architecture to use everything they remember in their next role — at a direct competitor — without restriction. In industries where core IP is carried in human memory (AI, biotech, chip design), this can destroy the commercial value of the NDA entirely. The clause appears as boilerplate in large company templates. Always delete or limit it before disclosing core IP.
Omitting the five standard exclusions
$25,000–$200,000 in wrongful breach claimsWithout the standard exclusions (prior possession, public domain, independent development, third-party receipt, compelled disclosure), recipients face breach claims based on information they legitimately possessed before the NDA, information that becomes public through no fault of theirs, or disclosures required by law enforcement. Defending a wrongful NDA breach claim — one where the exclusion should have applied but was not drafted — typically costs $25,000–$100,000 in attorney fees even when the recipient ultimately prevails.
Using a one-way NDA when the discussion will involve two-way disclosure
Your own confidential information is unprotectedSigning a one-way NDA protecting only the other party's information — then sharing your own confidential product plans, customer data, or technical specifications — leaves your information with no contractual protection whatsoever. Any breach claim you bring will fail because the NDA does not cover your disclosures. The fix requires only changing "Disclosing Party" to both parties — a change that takes five minutes. Never share proprietary information under a one-way NDA that does not cover your disclosures.
Ignoring the governing law clause in a multi-state deal
Non-compete or inevitable-disclosure obligations you did not expectAn NDA governed by Illinois law used in a deal where the employee or counterparty is California-based creates a jurisdiction conflict. California courts will likely refuse to enforce Illinois inevitable disclosure doctrine or any provision that functions as a non-compete — but the litigation to determine this is itself expensive. An Illinois-governed NDA used in a California employment context may be challenged for $50,000–$150,000 in legal fees before the governing law conflict is resolved. Always verify that the governing law matches the actual jurisdiction where the protected activity occurs.
Agreeing to a perpetual NDA term for general confidential information
Indefinite obligations over information that loses value quicklyBusiness strategies, pricing, and product roadmaps become obsolete — yet a perpetual NDA continues to create breach exposure long after the information has lost commercial sensitivity. Courts in California have expressed skepticism about perpetual terms for non-trade-secret confidential information. More practically: a perpetual NDA for a 2-year business relationship means your compliance obligations — monitoring disclosures, training employees, responding to breach claims — extend indefinitely. Negotiate a defined term (3–5 years) for general confidential information.
No audit or return-of-materials mechanism
$10,000–$75,000 in discovery disputes post-terminationNDAs without return or destruction provisions leave disclosing parties unable to confirm that confidential information has actually been removed from the recipient's systems after termination. In litigation, this gap becomes expensive: the disclosing party must subpoena forensic records and the recipient's IT infrastructure to establish what remains. A simple requirement — written certification of destruction within 30 days of termination, with a carve-out for automated backups — costs nothing to draft but saves significant post-termination discovery costs.

Check My NDA Free →14 Frequently Asked Questions
What is the legal definition of a trade secret under federal law?
Under the Defend Trade Secrets Act, 18 U.S.C. § 1839(3), a trade secret is any financial, business, scientific, technical, economic, or engineering information — including formulas, patterns, compilations, programs, devices, methods, techniques, or processes — that (a) the owner has taken reasonable measures to keep secret, and (b) derives independent economic value from not being generally known or readily ascertainable. Both prongs are required. Information that was never kept secret, or that derives no value from secrecy, is not a trade secret regardless of what the NDA calls it.
What is the difference between mutual and one-way NDA?
A one-way (unilateral) NDA protects information flowing in only one direction — typically from the disclosing party to a recipient. A mutual (bilateral) NDA protects information flowing in both directions and is appropriate when both parties will share confidential information. The practical difference: in a one-way NDA, only one party bears confidentiality obligations. Receiving a one-way NDA when the discussion will clearly involve two-way information exchange is a signal to push back and request a mutual structure.
What are the five standard carve-outs that every NDA should include?
The five standard exclusions are: (1) information already in the recipient's possession before disclosure; (2) information that is or becomes publicly available through no fault of the recipient; (3) information independently developed by the recipient without use of disclosed information; (4) information received from a third party with no confidentiality restriction; and (5) information that must be disclosed under applicable law or court order, provided the recipient gives prompt notice and cooperates in seeking a protective order.
What is a residuals clause and why is it dangerous?
A residuals clause permits the recipient to use information retained in the "unaided memory" of employees who had access to confidential information — for any purpose, including product development. Its practical effect: employees retain the right to use what they remember once the NDA expires. These clauses are standard in big tech NDA forms and are heavily negotiated. Always push to delete residuals clauses or narrow them to apply only after the NDA term ends and only to general skills, not specific product or business information.
What is the inevitable disclosure doctrine?
The inevitable disclosure doctrine allows an employer to obtain an injunction preventing a former employee from working for a competitor, even without proof of actual misappropriation, on the theory that the employee cannot perform their new role without inevitably disclosing the former employer's trade secrets. Recognized by the Seventh Circuit in PepsiCo v. Redmond (1995) and applied in Illinois and other states. California categorically rejects the doctrine — courts there require actual or threatened misappropriation.
What is the DTSA whistleblower immunity provision?
Under 18 U.S.C. § 1833(b), an individual cannot be held liable under federal or state trade secret law for disclosing a trade secret to a government official or attorney in confidence for the purpose of reporting a suspected legal violation, or in a court filing under seal. Employers must include this immunity notice in any NDA or employment agreement governing trade secrets — failure to include it forfeits the right to recover exemplary damages and attorney fees in a subsequent DTSA suit.
Can an NDA contain a hidden non-compete clause?
Yes, and this is one of the most common NDA traps. Overbroad confidential information definitions combined with a broadly drafted non-use obligation can effectively prevent the recipient from working in the same industry. Courts in California, Minnesota, and North Dakota have struck down NDA provisions that function as non-competes without being labeled as such. Any NDA provision that restricts what you can do — not just what you can say — should be evaluated under your state's non-compete law.
How long should an NDA term last?
Most commercial NDAs run 2–5 years. Perpetual terms are increasingly disfavored and unenforceable in some states for information that loses commercial value over time. The safest approach: a defined term (e.g., 3 years) for general confidential information, with a carve-out providing that obligations with respect to trade secrets continue for as long as the information qualifies as a trade secret under applicable law.
What damages are available for NDA breach?
Remedies typically include: (1) actual damages — lost profits, lost business value, cost to develop the misappropriated information; (2) unjust enrichment — the economic benefit from the misuse; (3) injunctive relief — available without proving actual damages; (4) exemplary damages — up to two times actual damages under DTSA for willful and malicious misappropriation; and (5) attorney fees — available under DTSA for willful misappropriation or bad-faith claims.
Does California enforce NDAs?
California enforces NDAs for true confidential information and trade secrets but applies heightened scrutiny to any NDA provision that functions as a restraint on trade. California Business & Professions Code § 16600 voids contracts that restrain a person from engaging in a lawful profession, trade, or business. California also rejects the inevitable disclosure doctrine. NDAs governing California employees must be narrow, specific about what qualifies as confidential, and free of provisions that could restrict future employment.
What is the difference between confidential information and a trade secret in an NDA?
Confidential information is a contractual concept: anything the parties agree to treat as confidential, regardless of legal status. Trade secrets are a legal concept defined by the DTSA and state UTSA: information that derives independent economic value from secrecy and for which reasonable secrecy measures are taken. A trade secret is always protectable under law, even without an NDA. Confidential information is only protected by contract. The distinction matters for how long obligations last, what remedies are available, and whether protection survives NDA expiration.
Should I sign an NDA before a job interview?
Pre-interview NDAs are common and generally acceptable for protecting specific confidential information shared during the interview. However, review the scope carefully: an NDA covering all information shared "in connection with potential employment" with a 5-year term could restrict you from discussing what you learned about the company's strategy or compensation practices. Push to narrow the scope to specific, identified categories of technical or business information rather than everything the company considers proprietary.
What is the return or destruction of materials obligation in an NDA?
Return or destruction provisions require the recipient to return or certify destruction of all confidential materials upon termination or at the disclosing party's request. This obligation is increasingly difficult to satisfy with enterprise backups and collaboration platforms. Negotiate a carve-out for information retained in automated backup systems that cannot be accessed in the ordinary course, and a standard certification of good-faith efforts rather than a warranty of complete destruction.
Can an NDA be enforced against a third party who receives the information?
NDAs are contracts — they bind only the signing parties. A third party who receives confidential information from the original recipient is not directly bound by the NDA unless they signed their own confidentiality agreement. However, under the DTSA and state trade secret laws, a third party who knowingly receives misappropriated trade secrets can face direct liability for misappropriation — regardless of whether they signed anything. This is how trade secret law extends protection beyond the NDA contract.
