Protecting Trade Secrets in India: NDAs and Employment Contracts

Updated 11 October 2026 · Fact-checked

Trade secrets in India are protected mainly by contract and the equitable duty of confidence, since there is no dedicated statute. NDAs and employment clauses bind people to secrecy. Courts enforce confidentiality, but non-competes after employment ends are generally void under Section 27 of the Indian Contract Act, 1872.

Understand Protection Methods: NDAs and Employment Contracts

A trade secret is confidential business information that has commercial value because it is secret, and which its owner has taken reasonable steps to keep secret. Examples are formulas, customer lists, pricing models and source code. India has no separate trade secrets Act. Protection comes from contract law, the equitable duty of confidence, and related laws such as the Copyright Act and the Information Technology Act.

Because the law depends on you taking steps, the protection methods are the heart of this topic. If a company does not show that it treated the information as secret, a court may refuse relief. So you must know the tools a company uses and the limits the law puts on each.

A non-disclosure agreement (NDA), also called a confidentiality agreement, is a contract where one party agrees not to disclose or misuse information received from another. It can be one-way (unilateral) or two-way (mutual). A good NDA defines the confidential information, states the permitted purpose, lists exclusions, fixes the duration, requires return or destruction of material, and names remedies and the governing law and forum.

Employment contracts add confidentiality clauses, assignment of work-related inventions and works, and sometimes restrictive covenants. A clause that restrains an employee during employment is usually valid, as the employee owes loyalty to the employer. A clause that restrains trade after employment ends faces Section 27 of the Indian Contract Act, 1872, which makes agreements in restraint of trade void. Indian courts have generally held post-termination non-competes unenforceable, while still protecting confidential information through confidentiality duties and injunctions.

Beyond contracts, companies use internal measures: marking documents confidential, need-to-know access, passwords and encryption, visitor controls, exit interviews, and training. These measures also serve as evidence of reasonable steps if a dispute reaches court.

Key rules to remember

Elements of a trade secret: Secret + Commercial value because secret + Reasonable steps to keep secret; This is the TRIPS Article 39 test. Use it to frame any answer on what is protected.
Post-employment non-compete: Section 27, Indian Contract Act, 1872: agreement in restraint of trade is void; Generally unenforceable after the employment ends. Do not say it is always valid.
During-employment restraint: Negative covenant during the term of service is generally enforceable; Based on the employee's duty of fidelity. Courts do not usually treat it as a Section 27 restraint.
Core NDA clauses: Definition + Purpose + Exclusions + Duration + Return/destruction + Remedies + Governing law and forum; Use as a drafting checklist.
Usual NDA exclusions: Public domain, already known, independently developed, lawfully received from a third party, disclosure required by law; Standard carve-outs that keep the NDA reasonable.
Remedies: Injunction + Damages or account of profits + Delivery up of material; Civil remedies in a suit for breach of confidence or contract.

How to solve Protection Methods: NDAs and Employment Contracts questions

Exam questions are case-based. Give the provision, analyse the facts, then conclude with a practical drafting or compliance point.

1Identify the information and test whether it is a trade secret: secret, commercially valuable, reasonable steps taken.
2Identify the source of the duty: NDA, employment contract, or equitable duty of confidence without a contract.
3Check the timing: is the restraint during employment or after it ended?
4Apply Section 27 of the Indian Contract Act, 1872 to any post-employment non-compete or restraint.
5Separate confidentiality from restraint: even if a non-compete fails, the confidentiality duty can still be enforced.
6Check the NDA for defects: vague definition, no duration, missing exclusions, unreasonable scope.
7State remedies available: injunction, damages or account of profits, delivery up.
8Conclude with a practical point: redraft the clause, add internal controls, or collect evidence of reasonable steps.

Quickest way: Three-question shortcut

When to use it: Use when time is short, for a short-note or a brief fact-based question.

Is it really secret and valued, and were reasonable steps taken? Say yes or no with a reason.
Is the restraint in-service or post-service? Post-service non-compete means Section 27 problem; confidentiality still stands.
Name the remedy (injunction and damages) and give one drafting fix.

Common mistakes in Protection Methods: NDAs and Employment Contracts

Saying post-employment non-competes are valid in India if they are reasonable.
Students import the English reasonableness test.
Fix: State that Section 27 voids restraints of trade, and that Indian courts generally refuse to enforce post-termination non-competes.
Treating the whole NDA as void when the non-compete fails.
Confusing confidentiality duties with restraint of trade.
Fix: Treat them separately. Confidentiality can be enforced even where the non-compete cannot.
Claiming there is a specific Indian trade secrets Act.
Assuming every IP right has its own statute.
Fix: Say protection comes from contract, equity and allied laws, and that there is no dedicated statute.
Ignoring internal measures and writing only about contracts.
Focus on legal documents.
Fix: Add access control, marking, training and exit procedures, and link them to the reasonable steps test.
Drafting an NDA with no definition or time limit.
Treating NDA as a standard form.
Fix: Use the clause checklist and add exclusions, duration and return of material.
Skipping the conclusion in a case question.
Stopping after explaining the law.
Fix: Always end with a clear finding and a practical recommendation.

Worked examples

Example 1

Veda Pharma Ltd, Hyderabad, has its process formula known to a few chemists. Chemist Arjun resigns and joins a rival in Pune. His contract has a clause: for two years after leaving he will not work for any competitor. Veda sues to stop him. Advise.

Show the solution

Information: a process formula known to few, valuable, and presumably guarded, so it can be a trade secret if reasonable steps were taken.
Source of duty: the employment contract and the equitable duty of confidence.
Timing: the non-compete operates after employment ended.
Law: Section 27 of the Indian Contract Act, 1872 makes agreements in restraint of trade void, so courts generally will not enforce this clause.
Confidentiality is separate: Arjun cannot use or disclose the formula, and Veda can seek an injunction if misuse is shown or threatened.
Practical point: Veda should prove its secrecy measures and focus the claim on misuse of the formula, not on stopping him from working.

Answer: The two-year post-employment non-compete is likely unenforceable under Section 27, but Veda can obtain an injunction and damages against use or disclosure of the formula if it shows the information is confidential and misuse is threatened or occurring.

Example 2

Kiran Tech Pvt Ltd plans to share its source code with a vendor for testing. List the key clauses you would draft in the NDA and one internal measure.

Show the solution

Choose the type: a unilateral NDA, as only Kiran Tech discloses.
Define confidential information to include source code, documentation and test results.
Limit use to the testing purpose only.
Add standard exclusions: public domain, independently developed, lawfully obtained from a third party, disclosure required by law.
Fix duration, and require return or destruction of all copies on completion.
Provide remedies, including injunction, and specify governing law and forum.
Internal measure: give the vendor access only through a controlled environment, with logs, on a need-to-know basis.

Answer: The NDA should be unilateral, with a clear definition, a purpose limit, exclusions, a stated duration, return or destruction of material, remedies and a governing law and forum clause, backed by restricted and logged access to the code.

Exam tips

Always quote Section 27 of the Indian Contract Act, 1872 when a question mentions a non-compete after leaving a job.
Frame answers in the three-part test: secret, commercial value, reasonable steps.
For drafting questions, list NDA clauses in a tidy checklist and add a one-line reason for each.
Separate confidentiality from restraint of trade in your conclusion.
Finish case answers with a practical recommendation on drafting or internal controls.

Practice questions from Protection of Trade Secrets

Protection Methods: NDAs and Employment Contracts: frequently asked questions

Is an NDA enforceable in India?

Yes, an NDA is a contract and is enforceable if it meets the requirements of a valid contract and is not an unlawful restraint. Courts can grant injunctions and damages for breach. A clear definition and reasonable scope help enforcement.

Is a non-compete clause enforceable in India?

During employment, such a restriction is generally enforceable. After employment ends, Section 27 of the Indian Contract Act, 1872 makes restraints of trade void, so courts generally do not enforce post-termination non-competes.

Can a company protect trade secrets without an NDA?

Yes. The equitable duty of confidence can apply even without a written contract, depending on the facts. But a written NDA makes proof far easier.

What internal measures help protect trade secrets?

Companies mark documents confidential, restrict access on a need-to-know basis, use passwords and encryption, train staff, and run exit procedures. These also show reasonable steps to keep the information secret.
