Evidence of exposure refers to the verified demonstration that a target party had the practical opportunity to observe, handle, or acquire proprietary information before the alleged infringement occurred. Within the rules of proof of access in Chinese trade secret law, this concept is one of the two main pillars used to establish liability alongside substantial similarity of the work. It involves identifying specific shared events such as joint research projects, shared supply chain meetings, or employment transfers that could have enabled the transfer of data.
A plaintiff must demonstrate that the defendant was in a position where the secret was visible, rather than relying on the mere theoretical possibility of remote hacking. This measure stops short of requiring a recorded video of the secret being read, focusing instead on the proximity and the interaction between the holder and the accused. If access is proven, the legal burden often shifts to the respondent to explain how they arrived at a identical technical solution independently.
Workplace interactions provide the most common setting for gathering the data points needed to verify how a secret could have moved across entities. When a senior developer moves between competing firms, the timing of their exit and entry provides the primary timeline for testing the proof of access claim. The court examines if the employee attended meetings where the specific confidential specifications were discussed in the months before their departure.
Physical logistics such as shared factory space or common storage areas on a server network also contribute to the strength of the evidence. Even if no physical documents were taken, the proximity to the technical material establishes a plausible path for the information. This phase of discovery often focuses on sign-in logs, email headers, and meeting minutes to establish the chain of connection between the two parties.
Administrative safeguards within a company are designed to limit the amount of proof of access that can be used against them in future disputes. By implementing strict folder permissions and clean desk policies, a business can argue that even if an employee were present, they did not have the specific clearance to view the restricted blueprints. When fighting a charge, a firm uses these internal controls to show a gap between the employee’s location and the secret’s actual location inside the building.
Successful evidence in this area relies on audit trails that record every instance a user opened a protected file on the company drive. If these records show zero interaction with the file, the defense against an infringement charge becomes significantly more robust. Establishing these boundaries early allows a company to isolate its teams and reduce the legal risks inherent in hiring from the same industry talent pool.
Legal consequences of establishing a clear link between a suspect and a proprietary document often lead to a formal requirement for the accused to show originality. Once proof of access is verified by the court, the focus changes from the actions of the secret holder to the development history of the competitor. The defendant must provide credible evidence of their own independent research and development process to avoid a judgment of infringement.
This might include early sketches, failed prototypes, or technical white papers dated before the alleged access took place. If the competitor cannot produce a verifiable paper trail for their own innovation, the court usually infers that the similarity between the products is the result of theft. This procedural mechanic makes the tracking of access points a high-priority task for compliance officers who oversee the entry of external contractors and partners into secure environments.
Proving trade secret theft in Chinese courts requires notarized evidence preservation, granular secret point definitions, and trigger proof for Article 32 burden shifting.
