Civil Litigation vs Criminal Complaint: Which Trade Secrets Enforcement Route in China?

Foreign companies operating in China face a difficult decision when their trade secrets are misappropriated: should they pursue a civil lawsuit for damages and injunctions, or file a criminal complaint that could lead to imprisonment for the perpetrators? This article provides a comprehensive comparison of both enforcement routes, examining the legal frameworks, procedural differences, evidentiary requirements, and practical outcomes to help foreign businesses choose the most effective strategy.

Understanding the Two Enforcement Pathways

China offers two primary legal routes for enforcing trade secret rights. Civil litigation allows the rights holder to sue the infringer directly in court, seeking monetary damages, injunctive relief, and other remedies. A criminal complaint, by contrast, involves reporting the violation to public security authorities (the police), who investigate and potentially prosecute the case through the criminal justice system. While both pathways ultimately aim to protect trade secrets, they operate under fundamentally different rules, timelines, and burdens of proof.

The choice between them is not merely academic. Each route carries distinct implications for the strategy, cost, duration, and ultimate outcome of an enforcement action. Many companies pursue both simultaneously — filing a criminal complaint while also preparing a civil lawsuit — but understanding the differences between the two is essential for making an informed decision.

Legal Framework

Civil Litigation Framework

Civil trade secret litigation in China is governed primarily by the Anti-Unfair Competition Law (AUCL), which defines trade secrets and prohibits their misappropriation. The AUCL was significantly amended in 2019 to strengthen protections, including increasing statutory damages, shifting the burden of proof in certain circumstances, and introducing punitive damages for malicious infringement. The Civil Procedure Law governs procedural aspects of civil cases, including rules on evidence, jurisdiction, and appeals.

Civil cases are heard in the Intellectual Property (IP) tribunals of intermediate people’s courts or, in some cases, basic people’s courts with designated jurisdiction over IP disputes. Since 2019, the最高人民法院 has also established specialized IP courts in Beijing, Shanghai, Guangzhou, and other major cities, which handle technically complex trade secret cases.

Criminal Complaint Framework

Criminal enforcement of trade secrets falls under Article 219 of the Criminal Law of the PRC, which criminalizes the theft, improper acquisition, disclosure, or use of trade secrets. The crime carries penalties ranging from criminal detention to imprisonment for up to 10 years, depending on the severity of the offense. The Supreme People’s Procuratorate and Ministry of Public Security have issued judicial interpretations specifying the thresholds for criminal prosecution, including minimum loss amounts required for different levels of punishment.

Criminal cases are investigated by public security authorities (economic crime investigation divisions) and prosecuted by the People’s Procuratorate. The case proceeds through the criminal court system, with the defendant entitled to legal representation and the protections of criminal procedure law.

Burden and Standard of Proof

One of the most significant differences between the two routes lies in the standard of proof. In civil litigation, the plaintiff must prove its case on a “balance of probabilities” (优势证据标准), meaning that the court must be persuaded that the infringement more likely occurred than not. This is a relatively lower standard compared to criminal proceedings, making it easier for rights holders to prevail in civil court.

In criminal proceedings, however, the prosecution must prove the case “beyond a reasonable doubt” (排除合理怀疑), a much higher standard. Every element of the crime — including the defendant’s intent, the existence of the trade secret, and the unauthorized use — must be established to the court’s complete satisfaction. This higher standard means that some cases that would succeed in civil litigation would not meet the criminal threshold.

Importantly, the 2019 amendments to the AUCL introduced a burden-shifting mechanism in civil cases: if the plaintiff provides preliminary evidence that the defendant had access to its trade secrets and that the defendant’s information is substantially identical, the burden shifts to the defendant to prove lawful acquisition. No such presumption exists in criminal proceedings, where the prosecution retains the full burden of proof throughout.

Evidence Collection

Evidence collection differs dramatically between the two routes. In civil litigation, the plaintiff bears primary responsibility for gathering and presenting evidence, though it can apply for court-ordered preservation measures. The Civil Procedure Law empowers courts to issue preservation orders for evidence that may be destroyed or concealed, and the 2019 AUCL amendments expressly provide for preservation of assets and evidence in trade secret cases.

Civil plaintiffs can use a range of investigative tools, including notarization of online infractions, forensic examination of digital devices (with appropriate consents), and witness testimony. However, they cannot compel third-party searches, wiretaps, or other coercive investigative measures.

In criminal cases, by contrast, the public security authorities have extensive investigative powers. They can execute search warrants, seize documents and electronic devices, compel testimony from witnesses, freeze bank accounts, and detain suspects. The police can also obtain cell tower data, communications records, and other information that would be inaccessible in a civil case. This coercive power often makes criminal complaints more effective at gathering evidence, especially when the infringer is uncooperative or has attempted to destroy evidence.

However, filing a criminal complaint means relinquishing control over the investigation. The police decide which leads to pursue, which evidence to collect, and how quickly to proceed. Rights holders who prefer to control the pace and scope of evidence gathering may find civil litigation more predictable.

Remedies and Outcomes

Civil Remedies

Civil litigation offers a range of remedies designed to compensate the rights holder and prevent future infringement:

• Damages: Actual losses, unjust profits of the infringer, or statutory damages. The 2019 amendments raised the statutory damages cap from RMB 3 million to RMB 5 million for non-malicious infringement, and introduced punitive damages of up to five times the actual damages for wilful and malicious infringement.
• Injunctions: Courts can issue preliminary and permanent injunctions to stop infringing activities, including orders to cease using the trade secret and to return or destroy confidential materials.
• Costs: Successful plaintiffs may recover reasonable litigation costs, including attorney fees and notarization expenses, though full recovery is uncommon.

Criminal Penalties

Criminal convictions carry penalties focused on punishment and deterrence:

• Imprisonment: Sentences range from up to three years for basic offenses, three to ten years for serious cases, and up to ten years for especially serious cases. The thresholds depend on the value of the loss caused.
• Fines: Criminal fines are imposed alongside imprisonment, calculated as a proportion of the illegal gains or at the court’s discretion.
• Social consequences: A criminal conviction in China carries severe social stigma. Convicted individuals may be banned from holding corporate officer positions, face travel restrictions, and suffer permanent damage to their careers and reputation.

Timeline and Duration

Civil trade secret litigation in China typically takes 12 to 24 months for a first-instance judgment, assuming no specialist technical appraisal is required. If the court orders a technical appraisal (鉴定) to determine whether the defendant’s information qualifies as a trade secret, the process can extend to 18 to 30 months. Appeals add another 6 to 12 months.

Preliminary injunctions, when granted, can be obtained relatively quickly — often within 15 to 30 days of filing. However, Chinese courts remain conservative in granting preliminary injunctions in trade secret cases, and success rates vary significantly by jurisdiction.

Criminal cases follow a different timeline. The public security investigation typically takes 30 to 60 days for initial investigation, extendable to 7 months for complex cases. The procuratorate then has 30 to 45 days to decide whether to prosecute. The criminal court trial itself takes 2 to 6 months, with appeals adding another 2 to 4 months. In total, a criminal case that proceeds to conviction typically requires 12 to 18 months from complaint to final judgment — comparable to civil litigation but with different pacing.

The key distinction is that criminal investigations can begin within days of filing a complaint, whereas civil litigation requires months of preparation before the first court hearing. For cases where ongoing infringement is causing irreparable harm, the faster initial action in criminal cases may be decisive.

Costs and Resource Requirements

Civil Litigation Costs

Civil trade secret litigation is expensive. Legal fees for a complex trade secret case in China typically range from RMB 300,000 to RMB 1.5 million or more, depending on the law firm, case complexity, and whether the matter goes to trial. Court filing fees are calculated as a percentage of the claimed damages, typically 0.5% to 2%, with higher claims attracting lower percentage rates. Technical appraisal fees, if required, can add RMB 100,000 to RMB 500,000. Notarization and evidence preservation costs add another RMB 50,000 to RMB 200,000.

Criminal Complaint Costs

Criminal complaints are significantly cheaper for the rights holder because the state bears the costs of investigation and prosecution. There are no court filing fees in criminal cases, and the public security authorities conduct fact-finding at public expense. The rights holder will typically need to engage legal counsel to prepare the complaint, gather initial evidence, and coordinate with authorities, at a cost of RMB 100,000 to RMB 400,000 — substantially less than full-scale civil litigation.

However, the lower cost comes with a trade-off in control. The rights holder cannot direct the investigation or decide which charges to pursue. If the authorities decline to prosecute — which happens in many trade secret cases due to the high evidentiary threshold — the rights holder has spent time and resources on a route that produced no result.

Practical Considerations for Foreign Companies

Choosing the Civil Route

Civil litigation is generally preferable when:

• Monetary compensation is the primary goal. Civil damages can provide meaningful financial recovery for losses caused by misappropriation.
• The trade secret is still confidential. Civil proceedings in China are not fully public — courts can issue protective orders and hold in-camera hearings to prevent further disclosure of the secret during litigation.
• The infringer is a former employee who has joined a competitor. Civil litigation allows the rights holder to seek an injunction preventing the competitor from using the misappropriated information.
• The legal theory is novel or complex. Civil courts are generally more willing than criminal authorities to consider sophisticated legal arguments about what constitutes a trade secret.
• The company wants to maintain control over case strategy. Civil litigation allows the rights holder to decide which claims to pursue, when to settle, and how to conduct discovery.

Choosing the Criminal Route

A criminal complaint may be the better choice when:

• Deterrence is the primary objective. The threat of imprisonment creates a powerful deterrent effect that damages alone cannot achieve.
• Evidence is in the infringer’s possession. Police search and seizure powers can recover documents, emails, and data that the plaintiff could not obtain through civil discovery.
• The infringer is an individual who has left the company. Individuals who have nothing to lose financially may be unmoved by the threat of civil damages but terrified of criminal prosecution.
• The misappropriation is clear and documented. Cases where the evidence of infringement is strong and unambiguous are more likely to succeed in the criminal justice system.
• The value of the misappropriated information exceeds the criminal threshold. Criminal prosecution requires minimum losses, typically RMB 300,000 for a first offense, but the threshold varies by region and is subject to judicial discretion.

The Dual-Track Strategy

Many successful enforcement actions in China use a dual-track strategy: file a criminal complaint to trigger police investigation and evidence collection, while simultaneously preparing a civil lawsuit. The criminal investigation can uncover evidence that would be unavailable in civil discovery alone, and the threat of criminal prosecution can pressure the defendant into a favorable settlement of the civil claim.

However, the dual-track approach requires careful coordination. The rights holder must be prepared to proceed with both routes simultaneously, which demands significant legal resources. Additionally, if the criminal investigation produces no result, the rights holder must be prepared to continue with civil litigation independently — a scenario that can feel like a significant investment of time and resources with uncertain returns.

Recent Trends and Judicial Developments

Chinese courts and enforcement authorities have shown increasing willingness to protect trade secrets in recent years. The 2019 AUCL amendments, the establishment of specialized IP courts, and the Supreme People’s Court’s issuance of detailed judicial interpretations on trade secret cases have all contributed to a more favorable enforcement environment. Between 2020 and 2025, the number of trade secret cases filed in Chinese courts increased by approximately 40%, with plaintiffs prevailing in an increasing proportion of cases.

Criminal enforcement has also become more robust. The Supreme People’s Procuratorate has issued guidance encouraging prosecutors to pursue trade secret cases more aggressively, and several high-profile cases have resulted in significant prison sentences for trade secret thieves. The establishment of specialized IP prosecution units in major cities has improved the quality and speed of criminal investigations.

Conclusion

The choice between civil litigation and criminal complaint for trade secret enforcement in China depends on a complex matrix of factors including the strength of available evidence, the nature of the infringer, the company’s strategic objectives, and its budget for enforcement. Civil litigation offers monetary recovery and injunctive relief but requires significant upfront investment and places the burden of evidence gathering on the plaintiff. Criminal complaints provide powerful state investigative powers and strong deterrent effects but require a higher standard of proof and relinquish control over case strategy to public authorities.

Foreign companies should evaluate each case on its merits and consider pursuing both routes simultaneously where circumstances permit. With China’s legal framework for trade secret protection continuing to strengthen, both enforcement pathways have become more viable in recent years, providing rights holders with meaningful options for protecting their intellectual property.
