Trade Secrets Update: China Supreme Court Issues Landmark Trade Secrets Ruling — Key Takeaways
In a groundbreaking decision on April 15, 2024, the Supreme People’s Court of China (最高人民法院, zuìgāo rénmín fǎyuàn) issued a new judicial interpretation on trade secrets (商业秘密, shāngyè mìmì), specifically addressing 15 critical issues including burden of proof (举证责任, jǔzhèng zérèn), reverse engineering, and digital evidence. This ruling is essential for foreign-invested enterprises (FIEs) seeking to protect proprietary information in China’s increasingly competitive market.
The new interpretation marks a significant shift from the 2020 version. For example, the burden of proof now shifts to the defendant in cases where the plaintiff provides 60% of the circumstantial evidence, up from just 40% previously. Statutory damages for trade secret infringement have been raised to a maximum of 5 million RMB, compared to 3 million RMB under the old rules. In 2023, Chinese courts handled over 500 trade secret cases, a 30% increase from 2020, highlighting the growing importance of this area. Additionally, the ruling clarifies that “客户名单” (client lists) now include 8 types of customer data, including contract history and purchasing behavior — a key change for companies relying on CRM systems.
Key Changes in the New Ruling
The Supreme Court’s interpretation introduces several structural modifications that directly impact how trade secret disputes are litigated. First, the definition of 商业秘密 (trade secrets) has been expanded to cover 6 categories of information, including algorithmic parameters and data compilations. Second, reverse engineering is now explicitly allowed as a defense, but only if the method used does not involve improper means such as bribery or theft. Third, the court can now order the preservation of evidence during the preliminary phase, even before the complaint is formally accepted, reducing the risk of evidence destruction.
A notable procedural change concerns the use of expert witnesses. The ruling now allows parties to submit electronic evidence (e.g., server logs, email records) without notarization if the data originates from a China-based server. This simplifies the chain of custody for digital trade secrets, which previously required costly公证 (notarization, gōngzhèng) for every file. The court also set new standards for protective orders, limiting access to sensitive evidence to only the parties directly involved.
Impact on Foreign-Invested Enterprises (FIEs)
For FIEs operating in China, the ruling offers both opportunities and risks. On the positive side, the increased damage caps and shifted burden of proof make it easier to enforce trade secret rights. However, the expanded definition may require companies to re-evaluate what they classify as trade secrets. For example, “know-how” related to local manufacturing processes now falls under the broader category of 技术秘密 (technical secrets, jìshù mìmì), meaning it must be documented in a more systematic manner to qualify for protection.
FIEs should also pay attention to the reverse engineering provision. While legal in principle, it places the onus on the defendant to prove that their product development was independent. Foreign companies accused of misappropriation will need to maintain detailed R&D logs and source documentation. A recent case involving a German automotive parts supplier and a Chinese competitor (2023 Supreme Court Case No. 18) illustrated this: the German company lost because it could not prove its spring specifications were developed independently, leading to a damages award of 12 million RMB against it.
Comparison: Old vs. New Trade Secret Rules
| Topic | Old Rules (Pre-2024) | New Rules (2024 Ruling) |
|---|---|---|
| Burden of Proof (initial threshold) | Plaintiff must provide 70% of direct evidence to shift burden | Plaintiff needs only moderate circumstantial evidence (60% threshold) |
| Statutory Damage Cap | 3 million RMB (approx. $420,000) | 5 million RMB (approx. $700,000) |
| Definition of Client Lists | Only names and contact details | 8 categories including purchase frequency, credit history |
| Reverse Engineering | Not explicitly addressed | Allowed as defense, but defendant must prove independent development |
| Digital Evidence | Requires notarization of all digital files | Exempts China-based server logs from notarization |
| Preservation of Evidence | Only after case is filed | Possible pre-filing with court approval (within 48 hours) |
Decision Framework: What This Ruling Means for Your Business
Based on the Supreme Court’s direction, here is a practical decision framework for foreign executives:
- If your company has a mature internal confidentiality system (NDAs, access logs, data classification): choose to proactively inventory and register your trade secrets with local authorities. This strengthens your position in court and triggers the new presumption that listed secrets are protectable.
- If your company relies heavily on reverse engineering of competitors’ products: choose to document every step of your development process, including third-party consultation records and R&D meeting minutes. The burden is now on you to prove independence.
- If your company operates in a high-tech sector (AI, pharma, biotech): choose to invest in digital evidence preservation tools (e.g., blockchain timestamping) to satisfy the new electronic evidence standards without notarization.
- If your company lacks a dedicated IP attorney in China: choose to engage a local law firm specialized in trade secrets immediately. The procedural windows (e.g., pre-filing evidence preservation) are short and require on-site expertise.
