How to Choose Between Civil and Criminal Trade Secrets Enforcement in China: 2026 Guide
When a foreign company discovers that a former employee, business partner, or competitor has misappropriated its trade secrets in China, the immediate question is always the same: should we pursue a civil lawsuit or file a criminal complaint? The answer has significant consequences for the cost, timeline, burden of proof, and ultimate remedy available. Choose civil enforcement and you control the case but bear the cost of discovery and litigation. Choose criminal enforcement and the state investigates on your behalf, but you lose control over the pace and scope of the proceeding. This guide provides a structured decision framework for foreign companies evaluating trade secrets enforcement options in China as of 2026, covering the full range of legal foundations, practical differences, recent policy developments, and a step-by-step process for making the right choice based on your specific circumstances.
The Legal Foundation: China’s Dual Enforcement Framework
China provides both civil and criminal remedies for trade secret misappropriation, grounded in two separate legal regimes that operate under different standards of proof, procedural rules, and remedial powers.
Civil Enforcement Framework
Civil trade secret enforcement in China is governed primarily by the Anti-Unfair Competition Law (AUCL), most recently amended in 2019 with important procedural updates continuing through 2025. The AUCL defines a trade secret as information that is (1) unknown to the public, (2) of commercial value, and (3) subject to reasonable confidentiality measures by the rights holder. Civil enforcement takes place in the People’s Courts, specifically in the Intellectual Property (IP) tribunals that exist in all intermediate courts and designated basic courts across China.
The maximum statutory damages for intentional trade secret misappropriation under the AUCL was increased to RMB 5 million in the 2019 amendment, with punitive damages of up to five times the actual loss available for malicious infringement. In practice, Chinese courts have awarded damages at the higher end of this range in an increasing number of cases since 2022, particularly where the defendant continued using the trade secrets after receiving a cease-and-desist notice. The 2024 Judicial Interpretation on Trade Secret Civil Cases further clarified the standards for calculating actual losses and defendants profits, making damage awards more predictable for rights holders.
Criminal Enforcement Framework
Criminal trade secret enforcement is governed by Article 219 of the Criminal Law of the People’s Republic of China. The crime of infringing on trade secrets is established when someone (1) acquires a trade secret through theft, bribery, fraud, coercion, or other improper means; (2) discloses, uses, or allows others to use a trade secret acquired through improper means; or (3) breaches a confidentiality obligation to disclose or use a trade secret. Criminal penalties include up to three years imprisonment for serious circumstances and three to ten years for especially serious circumstances.
Criminal cases are investigated by the Public Security Bureau (PSB) and prosecuted by the People’s Procuratorate. The standard of proof is beyond a reasonable doubt, which is significantly higher than the preponderance of evidence standard in civil cases. A criminal conviction requires proof that the defendant acted with criminal intent, which adds an additional element that does not exist in civil proceedings. The Supreme People’s Procuratorate reported a 28% year-on-year increase in trade secret prosecutions in 2025, reflecting both heightened enforcement priority and growing prosecutor expertise in this area.
Critical Differences Between the Two Paths
Burden of Proof
| Factor | Civil (AUCL) | Criminal (Criminal Law Art. 219) |
|---|---|---|
| Standard of Proof | Preponderance of evidence (greater than 50% likelihood) | Beyond a reasonable doubt (near certainty) |
| Plaintiff Burden | Must show trade secret exists, defendant had access, and use is probable | Must prove each element including criminal intent beyond reasonable doubt |
| Burden Shift to Defendant | Yes, once plaintiff shows access plus similarity, burden shifts to show independent development | No, burden remains on the prosecution throughout |
| Evidence Required | Circumstantial evidence can establish a prima facie case | Direct evidence preferred; circumstantial must be compelling |
Available Remedies
| Remedy | Civil | Criminal |
|---|---|---|
| Monetary Damages | Actual loss plus defendant profit, up to RMB 5M statutory, with punitive multiples up to 5x | Restitution to victim ordered by court (discretionary, often partial) |
| Injunctive Relief | Available, preliminary and permanent injunctions | Not directly available, court may order cessation of infringement |
| Custodial Sentences | Not available | Up to 10 years imprisonment |
| Fines | Not applicable | Criminal fines up to 5x illegal gains |
| Evidence Preservation | Available through court-ordered preservation (much improved since 2019) | PSB has broad search and seizure powers including dawn raids |
| Public Record | Civil judgments are public but less prominent | Criminal convictions are public with strong deterrent effect |
Timeline and Cost
| Aspect | Civil | Criminal |
|---|---|---|
| Typical Duration | 6-18 months (first instance), 8-24 months including appeal | 12-24 months investigation plus prosecution plus trial |
| Filing Fees | 0.5-1.5% of claimed damages (RMB 10K-100K typical) | None, state-funded investigation and prosecution |
| Attorney Fees | RMB 300K-1.5M for a full civil IP case | RMB 200K-800K for criminal representation |
| Expert Witness Fees | RMB 50K-200K for technical appraisal | RMB 30K-100K, PSB may conduct its own appraisal |
| Total Out-of-Pocket Cost | RMB 400K-2M | RMB 250K-1M |
Decision Framework: Which Path Fits Your Situation?
The decision between civil and criminal enforcement depends on seven key factors. Use the assessment below to evaluate your position.
Factor 1: Value of the Trade Secret
Civil enforcement is generally better suited for trade secrets with quantifiable market value above RMB 500,000. The civil courts have established damage calculation methodologies and are increasingly willing to award substantial compensation. For trade secrets with value below RMB 100,000, the cost of civil litigation may exceed any potential recovery, making the criminal route more attractive if the PSB is willing to pursue the case. Criminal enforcement requires a minimum economic loss of RMB 300,000 to meet the threshold for substantial loss, so very low-value secrets may not qualify for criminal action at all.
Factor 2: Strength of Evidence
Civil courts in China have significantly lowered the evidentiary bar for trade secret plaintiffs since the 2019 AUCL amendments. The burden-shifting mechanism means that once you prove (a) the trade secret exists, (b) the defendant had access to it, and (c) the defendant’s product or process is substantially similar, the burden shifts to the defendant to prove independent development. This is a substantial advantage for civil plaintiffs.
Criminal enforcement, by contrast, requires the prosecution to prove each element beyond a reasonable doubt, including the defendant’s criminal intent. If your evidence is largely circumstantial or relies on inferences, civil enforcement is significantly more likely to succeed. If you have direct evidence, such as emails showing intentional theft, downloaded files on a personal device, or testimony from a cooperating insider, criminal enforcement becomes more viable.
Factor 3: Urgency of Stopping Ongoing Use
If the defendant is actively using your trade secret in a product that is reaching the market, a preliminary injunction through civil proceedings can halt that use within weeks. Chinese courts have become more willing to grant preliminary injunctions in IP cases, particularly since the Supreme People’s Court issued guidance in 2020 encouraging their use in trade secret cases. Preliminary injunctions in trade secret cases increased by 47% from 2023 to 2025.
Criminal enforcement cannot provide preliminary injunctive relief. However, the PSB can conduct a dawn raid, seize computers and servers, and freeze bank accounts, all of which may effectively halt the defendant’s operations while the investigation proceeds. For urgent situations where physical evidence needs to be secured, the criminal path provides faster and more powerful immediate tools.
Factor 4: Identity of the Defendant
If the defendant is a former employee who has joined a competitor or started a competing business, both civil and criminal enforcement are viable. Chinese prosecutors and courts have become increasingly sophisticated in handling employee-driven trade secret theft, and the number of criminal convictions in this category has risen steadily since 2020.
If the defendant is a current or former business partner, civil enforcement is generally safer. Criminal prosecution of a business partner can escalate the relationship from commercial dispute to criminal confrontation, may trigger complex jurisdictional issues, and can create complications for ongoing business operations. A civil lawsuit can be settled without a criminal record, preserving the possibility of future business relations.
Factor 5: Deterrence Goal
If your primary goal is to send a message to other potential infringers, a criminal conviction carries far greater deterrent weight than a civil judgment. Criminal convictions in China are published and searchable, and the social stigma attached to criminal punishment, particularly imprisonment, is substantially greater than a civil judgment for damages. Companies in high-risk industries such as semiconductors, pharmaceuticals, automotive, and chemical formulations often pursue criminal enforcement for the first high-profile case to establish a deterrent precedent, then use civil enforcement for subsequent cases against less egregious infringers.
Factor 6: Control and Confidentiality
Civil enforcement gives the rights holder maximum control. You decide when to file, what claims to assert, what evidence to present, and whether to settle. The proceedings are confidential to a greater degree than criminal proceedings, and the court can issue protective orders covering sensitive business information disclosed during litigation.
Criminal enforcement transfers control to the PSB and procuratorate. They decide the pace of the investigation, what charges to file, and whether to accept a plea or proceed to trial. The rights holder becomes a victim-witness rather than a party to the proceeding. If the prosecutor decides not to pursue the case, your only recourse is a rarely granted application for reconsideration or a private prosecution, which effectively becomes a civil case anyway.
Factor 7: Jurisdiction and Local Enforcement Environment
Not all Chinese courts handle trade secret cases equally. The IP tribunals in Beijing, Shanghai, Guangzhou, and Shenzhen have established reputations for trade secret expertise and have issued some of the highest damage awards. Courts in smaller cities may have limited experience with complex trade secret cases and may be more conservative in their rulings.
PSB attitudes toward trade secret cases also vary significantly by location. The PSB in technology-focused cities like Shenzhen and Hangzhou has established specialized IP crime units with technical investigators. PSB units in other cities may be less familiar with trade secret cases and more reluctant to accept them.
Combined or Sequential Enforcement: The Civil Plus Criminal Strategy
Increasingly, sophisticated foreign companies are pursuing both civil and criminal enforcement in parallel or in sequence. This combined approach has several strategic advantages. Civil discovery can feed the criminal investigation, as evidence gathered through civil proceedings can be shared with the PSB to strengthen the criminal case. Criminal pressure drives civil settlement, as a criminal investigation, particularly a PSB raid or account freeze, creates enormous pressure on the defendant to settle the civil case on favorable terms. Risk allocation across two forums means that if the civil case fails on procedural grounds, the criminal case may still succeed if the PSB has gathered independent evidence, and conversely, if the criminal case is dropped for lack of criminal intent, the civil case may still succeed under the lower civil standard of proof.
Practical Considerations for the Combined Approach
- Timing: File the civil case first to begin discovery, then submit the criminal complaint once sufficient evidence is gathered. Alternatively, file both simultaneously and request a stay in the civil case pending the criminal investigation.
- Coordination: Appoint law firms with both civil IP litigation and criminal defense capabilities. Alternatively, appoint separate firms for civil and criminal work but require coordination through a single lead counsel.
- Information sharing across tracks: Work with counsel to establish a protocol for sharing evidence between proceedings without waiving privilege or violating procedural rules.
- Confidentiality: The criminal proceeding will inevitably expose more information to the public than a civil case. Consider protective measures such as sealed filings and redacted public documents.
Conclusion
The choice between civil and criminal trade secret enforcement in China is not binary. Many companies benefit from pursuing both paths, using civil litigation to secure immediate injunctive relief and discovery while leveraging criminal investigation to maximize pressure and deterrence. The combined approach has become the standard practice for sophisticated IP enforcement in China’s major commercial centers. Foreign companies should conduct the seven-factor assessment covering trade secret value, evidence strength, urgency, defendant identity, deterrence goal, control preference, and local enforcement environment before deciding. In most cases where the trade secret has clear value above RMB 500,000 and the evidence supports both paths, a dual-track strategy with civil litigation filed first followed by a criminal complaint at the appropriate moment will produce the best outcome. Engage Chinese counsel with specific experience in trade secret enforcement before taking any irreversible steps, as the initial 48 hours following discovery of a breach are critical.
