A foreign manufacturer sues a former distributor in Korea for misusing proprietary designs. The key evidence is a set of engineering drawings and pricing algorithms—exactly the type of information that cannot become public. The question is not only whether you can win the case, but also how you can litigate without exposing the very trade secrets you are trying to protect. That is where Korea protective orders and confidentiality rules become critical.

In 2026, Korean courts increasingly recognize the need to balance open justice with protection of sensitive information. The Korea protective orders regime provides tools to keep trade secrets confidential while still allowing litigation to proceed. For foreign companies, understanding how these tools work can determine whether Korea is a safe and effective forum for enforcement.

Below is a practical guide to confidentiality protections in Korean litigation, with special focus on trade secret disputes.

Korea protective orders: legal foundations

Korean law provides multiple layers of confidentiality protection in trade secret cases. The most commonly cited legal basis is the Unfair Competition Prevention and Trade Secret Protection Act, which expressly allows courts to issue confidentiality orders in trade secret litigation. In particular, Article 14-4 of that Act authorizes confidentiality orders to restrict access to sensitive information and impose obligations on parties, attorneys, and other participants.

Additional protection can arise under the Civil Procedure Act, which allows courts to conduct non-public hearings or limit access to case records in exceptional circumstances. Courts may also impose restrictions related to evidence inspection and copying to prevent leakage.

What a confidentiality order can do

A confidentiality order typically:

Limits access to designated documents to specific individuals
Prohibits disclosure of trade secrets outside the litigation
Requires destruction or return of confidential materials after trial
Imposes sanctions for violations

For foreign plaintiffs, these orders can make it feasible to litigate in Korea without exposing core IP.

How confidentiality orders are used in practice

In a trade secret case, the court will often request that the parties identify which materials are confidential and explain why disclosure would cause harm. The judge may review the documents in camera (privately) and issue a tailored order.

Typical scenarios

Source code and algorithms: Courts limit access to outside counsel and technical experts only.
Manufacturing process documents: Access may be granted to a small number of designated employees bound by confidentiality.
Pricing and customer data: Disclosure is often restricted to prevent competitive harm.

Foreign companies should expect to submit supporting declarations that explain the commercial sensitivity of the information and how disclosure would cause irreparable harm.

Interaction with evidence disclosure rules

Korean civil litigation does not have U.S.-style discovery. Instead, parties rely on document production orders, evidence preservation procedures, and court-directed disclosure mechanisms. In trade secret cases, these procedures are often coupled with confidentiality orders.

For example, a party can seek a document production order under the Civil Procedure Act, and the court can issue a confidentiality order at the same time. This allows evidence to be produced while minimizing leakage risk.

Key steps for foreign plaintiffs

1) Define the trade secret clearly

Courts will not grant confidentiality protection if the information is vague. A trade secret should be defined with specificity, including its technical or commercial features. This definition is also essential under Unfair Competition Prevention and Trade Secret Protection Act Article 2, which defines what qualifies as a trade secret.

2) Show reasonable secrecy measures

Korean courts examine whether the plaintiff took reasonable measures to keep the information confidential. This includes internal access controls, NDAs, and security systems. A strong internal compliance record makes it easier to obtain a confidentiality order.

3) Request a protective order early

Do not wait until evidence is about to be submitted. File for a confidentiality order early and propose a concrete, workable protocol. Courts appreciate practical solutions.

4) Manage cross-border access

Foreign head office teams often need to review evidence. Your confidentiality order should allow access to specific foreign personnel while maintaining Korean legal compliance. This can be done by naming individuals and requiring signed confidentiality undertakings.

Common mistakes that undermine protection

Over-designating documents as confidential without justification
Failing to segregate confidential and non-confidential materials
Late requests after evidence has already been filed
Inadequate internal secrecy measures that weaken the trade secret claim itself

What a well-drafted confidentiality protocol looks like

Foreign plaintiffs often succeed when they present the court with a clear, practical protocol rather than a generic request. A strong protocol usually includes:

Categories of confidential information (e.g., source code, manufacturing processes, customer pricing)
Access tiers (outside counsel only, designated experts, in-house reviewers)
Secure review methods (data rooms, offline review, redacted copies)
Handling rules for translations, summaries, and expert reports
Post-trial destruction or return procedures

These details show the court that you are minimizing risk while allowing the other side to defend itself fairly.

Sanctions and enforcement risk

Confidentiality orders are meaningful because violations can lead to court sanctions and, in serious cases, potential civil or criminal exposure under the Unfair Competition Prevention and Trade Secret Protection Act. Courts can impose penalties for breach, and a violation can undermine the violator’s credibility across the entire case. This is a practical reason to insist on a clear protocol and written undertakings by all recipients.

How protective orders interact with arbitration

Many foreign businesses prefer arbitration for cross-border disputes, but trade secret issues still arise in Korean-seated arbitrations. While arbitral tribunals can issue confidentiality orders, enforcement can be more complex. If you expect to seek court assistance for evidence collection or injunctions, it is important to ensure that your arbitration clause allows for court support without waiving confidentiality protections.

Tactical considerations for defendants

If you are defending against a trade secret claim in Korea, protective orders also matter. Overly broad confidentiality designations can limit your ability to prepare a defense. Defendants should:

Challenge over-designation and seek narrower categories
Request access for technical experts who can evaluate the alleged trade secret
Ensure that any restrictions do not prevent internal decision-makers from understanding the case

A balanced order protects secrets while ensuring procedural fairness.

Comparing Korea with U.S. and EU approaches

The U.S. typically uses protective orders under federal or state civil procedure rules, and discovery is broad. EU jurisdictions vary, but many allow confidentiality measures similar to Korea’s approach in trade secret litigation. Korea’s system is more targeted, reflecting its narrower disclosure regime, which can be an advantage for companies concerned about broad discovery risks.

Coordination with injunctions and evidence preservation

Trade secret cases often involve urgent relief. Plaintiffs can seek preliminary injunctions to stop use or disclosure of secrets and apply for evidence preservation before a full hearing. While the legal basis varies, courts can combine these procedures with confidentiality orders to prevent leakage during expedited proceedings.

For example, a foreign company may request a preliminary injunction while simultaneously seeking a protective order so that technical evidence can be reviewed without public exposure. This coordination is vital when speed and secrecy are both required.

Managing translations and cross-border teams

Litigation in Korea typically requires Korean-language filings. When confidential materials must be translated, the translation team should be explicitly included in the confidentiality order, and translation workflows should be controlled through secure review systems. Foreign head office reviewers should also be named in the order, with written undertakings to comply with Korean confidentiality obligations.

Practical tips and key takeaways

Use confidentiality orders proactively in trade secret disputes.
Define the trade secret precisely to satisfy legal standards under Article 2 of the Trade Secret Act.
Demonstrate secrecy controls with evidence of access restrictions and NDAs.
Coordinate with evidence procedures like document production orders to align disclosure with protection.
Plan cross-border review carefully to avoid accidental leaks.

Criminal proceedings and parallel investigations

Trade secret disputes sometimes run parallel to criminal complaints, especially when misappropriation involves former employees. While confidentiality orders are primarily a civil litigation tool, they can influence how evidence is shared in parallel tracks. Coordinating the narrative, evidence handling, and confidentiality expectations across civil and criminal channels is essential to avoid inconsistent disclosures.

Conclusion

For foreign companies litigating in Korea, Korea protective orders are a crucial tool for safeguarding trade secrets. By grounding your strategy in the Trade Secret Act, documenting internal secrecy measures, and requesting confidentiality orders early, you can pursue enforcement without sacrificing your competitive advantage.
