China Amends Anti-Unfair Competition Law – Stronger Trade Secret Protection for Foreign Companies

For foreign companies operating in China, trade secret protection has long been a source of anxiety. High-profile misappropriation cases, the challenge of enforcing rights in an unfamiliar legal system, and a perception that Chinese courts afforded weaker protection to foreign trade secret holders than to domestic ones combined to create a climate of caution. Many foreign companies responded by withholding their most valuable technical information from their Chinese operations—a protective measure that also prevented them from fully leveraging China's manufacturing capabilities and R&D talent. China's newly amended Anti-Unfair Competition Law directly addresses these concerns. The amendments expand the statutory definition of trade secrets, substantially increase statutory damages for misappropriation, and—most significantly—ease the burden of proof for trade secret owners seeking to establish misappropriation in court. These are not marginal adjustments. They represent a structural strengthening of China trade secret protection that brings the legal framework closer to the standards foreign companies expect from mature IP jurisdictions. For foreign companies that have limited their China operations due to trade secret concerns, or that have experienced misappropriation and found the previous legal framework inadequate, the amendments create new opportunities for protection and enforcement. This guide analyzes the key provisions of the amended law, explains how they change the enforcement landscape, and outlines practical steps for foreign companies to leverage the stronger protections now available.

1. Expanded Definition: What Now Qualifies as a Protected Trade Secret

The amended Anti-Unfair Competition Law significantly expands the statutory definition of trade secrets, broadening the scope of protected information and clarifying categories that were ambiguous under the previous law. For foreign companies, this expansion means that more of their valuable business and technical information now falls within the law's protective scope.

Under the previous definition, a trade secret was defined as technical or business information that was not publicly known, that could bring economic benefits to the rights holder, that had practical utility, and that the rights holder had taken measures to keep confidential. The amended definition retains these core elements but expands and clarifies each one. The requirement of "practical utility" has been broadened to encompass information with "commercial value," removing the implication that the information must have immediate practical application. This change brings within the law's protection early-stage research data, experimental results, negative findings, and works in progress that have commercial value but may not yet have demonstrated practical utility—precisely the types of information that foreign companies are often most concerned about protecting during the R&D phase.

The amended law explicitly includes several categories of information that were not specifically enumerated in the previous definition. These include algorithms and AI training data, customer lists and preference data, supply chain and sourcing information, business plans and strategic analyses, and financial data and pricing methodologies. For foreign companies in technology, consumer goods, and professional services sectors, these explicit categories provide clarity that specific types of commercially valuable confidential information are protected. A foreign e-commerce company's customer preference algorithms, a foreign manufacturer's supplier qualification data, or a foreign consulting firm's pricing methodology now fall unambiguously within the statutory definition.

The amended law also clarifies that information can qualify as a trade secret even if it is compiled from publicly available sources, provided the compilation itself represents a valuable aggregation, curation, or analysis that is not publicly known. This is particularly significant for foreign companies whose competitive advantage lies not in individual data points but in how those data points are collected, organized, and analyzed. A market analysis compiled from publicly available government statistics and industry reports can qualify as a trade secret if the specific compilation methodology, analytical framework, and resulting insights are maintained as confidential and have commercial value.

2. Increased Statutory Damages: The New Compensation Framework

The amended law introduces a substantially strengthened damages framework that increases both the maximum statutory damages available and the methods by which damages can be calculated. This is perhaps the most practically significant change for foreign companies that have experienced trade secret misappropriation and found the previous compensation levels inadequate.

Under the previous law, statutory damages for trade secret misappropriation were capped at RMB 3 million. This cap, while not trivial, was widely regarded as insufficient to deter sophisticated misappropriation or to adequately compensate rights holders for the commercial harm caused by trade secret theft. The amended law raises the statutory damages cap to RMB 10 million, more than tripling the previous maximum. For cases involving willful misappropriation or misappropriation that causes particularly serious harm, the amended law introduces punitive damages of up to five times the actual damages suffered. This punitive damages provision brings trade secret remedies in line with the punitive damages available for willful trademark and patent infringement under Chinese law, creating a consistent deterrent framework across IP categories.

The amended law also expands the methods by which damages can be calculated. The previous law primarily relied on the rights holder's actual losses or the infringer's illicit profits as damage measures. The amended law adds a reasonable royalty approach, allowing rights holders to claim damages based on the royalty that would have been payable had the infringer lawfully licensed the trade secret. It also permits courts to consider the commercial value of the trade secret itself—including its development cost, its contribution to the rights holder's business, and its remaining useful life—when calculating damages. These expanded calculation methods provide rights holders with multiple pathways to establish compensable harm, reducing the risk that damages will be limited by the difficulty of proving specific lost profits or infringer gains.

The amended law also addresses the costs of enforcement. Courts are now expressly authorized to award reasonable enforcement costs—including attorney fees, investigation expenses, expert witness fees, and evidence preservation costs—to prevailing trade secret owners. This cost-shifting provision reduces the net financial burden of enforcement and makes it more feasible for foreign companies to pursue meritorious cases even when the anticipated damages recovery might be moderate relative to litigation costs.

3. The Shifted Burden of Proof: A Game-Changer for Trade Secret Owners

The most strategically significant change in the amended law is the shift in the burden of proof for establishing trade secret misappropriation. Under the previous framework, the trade secret owner bore the full burden of proving that the defendant had misappropriated the trade secret—a burden that was often impossible to meet because the evidence of misappropriation was in the defendant's possession. The amended law introduces a burden-shifting mechanism that substantially eases the evidentiary burden on trade secret owners.

Under the new framework, the trade secret owner must establish three elements to trigger the burden shift. First, the owner must establish that it holds a protected trade secret under the amended definition. Second, the owner must present evidence that the defendant had access to or opportunity to obtain the trade secret. Third, the owner must present evidence that the defendant's products, processes, or business activities are substantially similar to or demonstrably derived from the trade secret. Once these three elements are established, the burden shifts to the defendant to prove that it independently developed the information, lawfully acquired it from another source, or otherwise did not misappropriate the trade secret.

This burden-shifting mechanism is particularly valuable for foreign companies in several common misappropriation scenarios. When a former employee joins a competitor and the competitor shortly thereafter introduces a product with features that closely match the former employer's trade secret technology, the foreign company can establish access through the former employee's employment history and similarity through product analysis. The burden then shifts to the competitor to explain the origin of its technology. When a joint venture partner or contract manufacturer begins producing products that incorporate the foreign company's confidential technical information for other customers, the foreign company can establish access through the business relationship and similarity through product comparison. The burden shifts to the partner or manufacturer to prove independent development.

The amended law also addresses the preservation of evidence during litigation. Courts are now expressly authorized to order defendants to produce relevant evidence in their possession, including technical documentation, business records, and electronic data. Defendants who refuse to produce ordered evidence without legitimate justification face adverse inferences—the court may deem the trade secret owner's allegations regarding the withheld evidence to be established. This evidence production mechanism, combined with the burden shift, significantly reduces the information asymmetry that has historically disadvantaged trade secret owners in Chinese litigation.

4. New Preliminary Injunction Provisions

The amended Anti-Unfair Competition Law introduces explicit provisions for preliminary injunctions in trade secret cases, filling a significant gap in the previous legal framework. The availability of preliminary injunctive relief is critical in trade secret cases because the harm from misappropriation is often irreparable—once a trade secret is disclosed or used by a competitor, the competitive advantage it provided is permanently lost. The previous law did not specifically address preliminary injunctions for trade secret cases, leaving courts to apply general civil procedure principles with uncertain results.

The amended law authorizes courts to issue preliminary injunctions prohibiting the use or disclosure of alleged trade secrets pending final judgment. To obtain a preliminary injunction, the trade secret owner must demonstrate a likelihood of success on the merits, irreparable harm if the injunction is not granted, and that the balance of hardships favors the injunction. The court may require the trade secret owner to post a bond to cover potential damages to the defendant if the injunction is later determined to have been wrongly issued.

The preliminary injunction provisions are particularly important for foreign companies in several scenarios. When a former employee has joined a competitor and is in a position to disclose trade secrets, a preliminary injunction can prevent that disclosure before it occurs. When a competitor has obtained trade secrets and is preparing to launch a product incorporating them, a preliminary injunction can prevent the product launch and the resulting market harm. When trade secrets have been disclosed to a third party who has not yet used them, a preliminary injunction can prevent further dissemination. The availability of preliminary relief transforms trade secret enforcement from a purely retrospective remedy—damages after the harm has occurred—to a prospective remedy that can prevent the harm from occurring in the first place.

The amended law also provides for ex parte preliminary injunctions in cases of exceptional urgency, where notice to the defendant would create a risk of evidence destruction or immediate irreparable harm. Ex parte relief is subject to heightened scrutiny and shorter duration, and the defendant must be given an opportunity to be heard promptly after the injunction issues. This provision addresses the common concern that notifying a defendant of impending enforcement action may trigger destruction of evidence before the court can act.

5. Practical Steps for Foreign Companies to Strengthen Protection

The amended law provides stronger legal tools, but those tools are effective only if foreign companies have taken the foundational steps that the law requires. The amended definition of trade secrets retains the requirement that the rights holder must have taken "reasonable measures" to maintain confidentiality. Without such measures, valuable information may not qualify for protection regardless of the law's other improvements.

• Implement and document confidentiality measures systematically. The amended law's "reasonable measures" requirement demands more than including confidentiality clauses in employment contracts. Implement layered protection including access controls, need-to-know restrictions, technical protection measures for digital information, visitor and vendor confidentiality protocols, and departure procedures for exiting employees. Document each measure and its implementation, as this documentation will be critical evidence in any enforcement action.
• Conduct trade secret identification and classification. Formally identify and classify the trade secrets within your Chinese operations. Create a trade secret inventory that describes each trade secret, its commercial value, the measures taken to protect it, and the personnel with authorized access. This inventory serves both as a management tool and as evidence in enforcement proceedings. Regular updates ensure that new trade secrets are captured as they develop.
• Strengthen employee and partner agreements. Review and update employment agreements, non-disclosure agreements, and business partner contracts to reflect the amended law's expanded trade secret definition and enhanced remedies. Include specific identification of the types of information considered trade secrets, clear confidentiality obligations that survive termination of the relationship, and acknowledgment of the legal consequences of misappropriation under the amended law.
• Establish trade secret compliance monitoring. Implement monitoring systems to detect potential misappropriation. Monitor employee departure patterns, unusual data access or download activity, and competitor product introductions that may indicate use of your trade secrets. Early detection enables rapid response before the harm becomes irreparable—particularly important given the new preliminary injunction provisions.
• Prepare enforcement-ready evidence packages. For your most valuable trade secrets, prepare evidence packages that would support rapid enforcement action: documentation of the trade secret's development and commercial value, records of the protective measures implemented, access logs showing who had access and when, and any agreements or acknowledgments signed by personnel with access. Pre-prepared evidence packages dramatically reduce the time required to initiate enforcement when misappropriation is detected.

The amended Anti-Unfair Competition Law provides the strongest trade secret protection framework China has ever offered to foreign companies. But the law's protections are not self-executing. Foreign companies that invest in the foundational compliance measures the law requires, that prepare for enforcement before misappropriation occurs, and that leverage the new burden-shifting and preliminary injunction provisions strategically will be positioned to protect their valuable confidential information more effectively than was possible under the previous legal framework.

Summary: China's amended Anti-Unfair Competition Law delivers a structural strengthening of trade secret protection that directly addresses long-standing concerns of foreign companies operating in China. The expanded statutory definition of trade secrets broadens the "practical utility" requirement to "commercial value," explicitly protects algorithms, customer data, supply chain information, and business plans, and extends protection to valuable compilations of publicly available information—bringing more of foreign companies' commercially valuable confidential information within the law's protective scope. The damages framework is substantially strengthened, with statutory damages raised from RMB 3 million to RMB 10 million, punitive damages of up to five times actual damages for willful or serious misappropriation, expanded calculation methods including reasonable royalty and trade secret commercial value approaches, and court authority to award full enforcement costs to prevailing rights holders. The most strategically significant change is the shifted burden of proof: once the trade secret owner establishes ownership of a protected secret, the defendant's access to it, and substantial similarity of the defendant's products or processes, the burden shifts to the defendant to prove independent development or lawful acquisition. Courts can now compel evidence production with adverse inferences for unjustified refusal, addressing the information asymmetry that historically disadvantaged rights holders. New preliminary injunction provisions authorize courts to prohibit use or disclosure of trade secrets pending final judgment, with ex parte relief available in cases of exceptional urgency, transforming enforcement from purely retrospective damages to prospective prevention. Foreign companies should respond by implementing and documenting layered confidentiality measures, conducting formal trade secret identification and classification, strengthening employee and partner agreements, establishing compliance monitoring, and preparing enforcement-ready evidence packages for their most valuable trade secrets. The amended law provides the strongest China trade secret protection framework to date; foreign companies that invest in the foundational measures the law requires will be positioned to protect their confidential information and enforce their rights more effectively than ever before.
