Shanghai Court Grants Pre-Litigation Preservation Order in Trade Secrets Dispute: Key Takeaways for Foreign Executives
On February 27, 2025, a Shanghai intermediate court granted a pre-litigation preservation order (诉前证据保全, sù qián zhèngjù bǎoquán) in a trade secrets dispute between a German automotive supplier and a former employee who had joined a Chinese competitor. The order was issued within 48 hours of the application, allowing the court to seal 27 servers and 14 hard drives at the competitor’s site before any formal lawsuit was filed — a speed and scope that foreign executives in China must understand as a new operational reality.
The case marks a sharp acceleration in China’s enforcement of trade secret protections. Under the 2019 amendments to the Anti-Unfair Competition Law (反不正当竞争法, fǎn bù zhèngdāng jìngzhēng fǎ), Chinese courts have progressively strengthened remedies for intellectual property holders. In 2024, the Shanghai Intellectual Property Court reported that it handled 1,247 trade secret cases, up from 892 in 2022 — a 39.8% increase. Pre-litigation preservation orders were granted in 67% of IP cases where they were requested in 2024, compared to just 23% in 2019.
Case Background: The Alleged Misappropriation
The German supplier, which operates a wholly foreign-owned enterprise (外商独资企业, WFOE, wàishāng dúzī qǐyè) in Shanghai, alleged that a senior engineer who resigned in November 2024 had downloaded over 15,000 files from the company’s server during his final week — including engine calibration data, supplier lists, and manufacturing process documentation. The company discovered the breach through its internal data loss prevention (DLP) audit, which flagged the unusual volume of outbound data traffic from the employee’s terminal.
The court’s decision to grant the preservation order without a hearing underscores how seriously Chinese judicial authorities now treat trade secret claims. The applicant posted a bond of 500,000 RMB (approximately $69,000), which the court held as security against potential damages to the respondent if the application was found to be abusive. The preservation order allowed forensic teams to image the seized devices at a neutral IT forensics lab within 72 hours, with both parties’ legal representatives present.
Legal Framework: Trade Secrets Protection in China After 2019
China’s 2019 amendment to the Anti-Unfair Competition Law significantly expanded the definition of trade secrets (商业秘密, shāngyè mìmì) and shifted the burden of proof. Under Article 32, once the rights holder provides preliminary evidence of misappropriation and shows “reasonable steps” to protect the secret, the burden shifts to the alleged infringer to prove that no misappropriation occurred. This is a critical shift for foreign firms: you no longer need to prove how the secret was taken — you only need to raise a credible inference.
Pre-litigation preservation orders are governed by the Supreme People’s Court’s 2020 “Interpretation on Evidence Preservation in Intellectual Property Cases.” The standard requires the applicant to demonstrate: (1) there is a reasonable likelihood that evidence will be destroyed or lost; (2) the evidence is material to the case; and (3) the preservation is necessary and proportionate. The Shanghai court applied this standard rigorously, noting that the 15,000-file download and the employee’s rapid transition to a direct competitor satisfied the “reasonable likelihood” threshold.
Why This Order Matters for Foreign Executives
For foreign companies operating in China, this case signals three structural changes in the enforcement environment. First, speed: the 48-hour turnaround means that a trade secret leak can be frozen before the counterparty has a chance to destroy evidence. In previous years, foreign firms often complained that by the time they filed a lawsuit, evidence had already been deleted or transferred offshore. Second, scope: the court did not require the applicant to identify specific file names or folder paths — it accepted the aggregate volume of downloads as sufficient suspicion. Third, cost: the 500,000 RMB bond is relatively modest for a mid-sized foreign-invested enterprise, meaning the financial barrier to obtaining such orders is lower than many executives assume.
However, this enforcement power cuts both ways. Chinese competitors are increasingly using the same tools against foreign companies. In 2024, 41% of pre-litigation preservation applications were filed by domestic Chinese firms against foreign-invested companies, according to a study by the China Intellectual Property Law Association. If your WFOE receives a preservation order, you must immediately secure legal counsel experienced in these proceedings — failure to respond within the statutory period (usually 30 days) can result in the court converting the preservation into a preliminary injunction.
| Factor | Pre-Litigation Preservation Order | Traditional M&A Litigation |
|---|---|---|
| Time to obtain evidence freeze | 48–72 hours | 4–8 weeks |
| Bond required | 300,000–1,000,000 RMB | None for filing; trial bond may apply |
| Evidence type preserved | Digital, physical, and documentary | Often limited to subpoenas and discovery |
| Risk of evidence destruction | Minimal (order is executed same day) | High (counterparty has weeks to act) |
| Cost of proceeding (legal+forensic fees) | 150,000–300,000 RMB | 400,000–800,000+ RMB |
| Success rate (2024 data) | 67% for IP cases | 52% for trade secret trials |
Practical Implications for Your China Operations
This case should prompt foreign executives to conduct a gap analysis of their internal trade secret protection protocols. The German supplier succeeded in part because it had a documented DLP audit trail — the 15,000-file download was flagged by an automated system that the company had installed in 2022. Without such a system, you would have no evidence of “reasonable steps” to protect the secret, which is a precondition for shifting the burden of proof under Article 32.
Additionally, the case highlights the importance of employment contract language. The departing engineer had signed a “Non-Competition and Confidentiality Agreement” (竞业限制与保密协议, jìngyè xiànzhì yǔ bǎomì xiéyì) that explicitly listed the categories of information considered trade secrets. The German supplier had also paid the statutory non-compete compensation (100% of the employee’s average monthly salary over the prior year), making the non-compete enforceable. If your company does not pay this compensation monthly during the non-compete period, the agreement is void.
Decision Framework: When to Seek a Pre-Litigation Preservation Order
If you discover a large-volume data download (e.g., >5,000 files) by a departing employee who joins a direct competitor, choose a pre-litigation preservation application — the speed advantage outweighs the bond cost. If the suspected leak involves fewer than 500 files and no immediate competitor transition, choose traditional evidence preservation (e.g., notarization of access logs) — the legal cost is lower and the bond requirement may not justify the expedited process.
Three Pitfalls Foreign Companies Must Avoid
NEXT STEPS
- Conduct an internal trade secret audit — review your DLP logs, non-compete payments, and confidentiality agreements against the 2019 Anti-Unfair Competition Law standards. Use our audit checklist: Trade Secret Audit Checklist for Foreign Firms in China.
- Update your employment contracts — ensure your non-compete and confidentiality agreements include a definition of trade secrets that covers digital assets and cloud-based data. See our template guide: Drafting Enforceable Non-Compete Clauses in China.
- Establish a pre-litigation emergency protocol — designate a law firm with on-call capacity for 48-hour preservation applications. We recommend: IP Emergency Response Plan for China Operations.
