Preserving Evidence and Establishing Proof in Chinese Patent Litigation
Establishing proof in Chinese patent litigation demands front-loaded notarized evidence, strict chains of custody, and aggressive judicial preservation orders.
Burden of Proof Shifting
Meaning
Judicial procedures in civil disputes generally assign the duty of demonstrating a claim to the party that asserts it. However, burden of proof shifting relocates this obligation to the opposing party once certain preliminary facts are established, requiring them to disprove the allegation.
Statutory Application
Intellectual property disputes and environmental litigation frequently employ this mechanism to rebalance the relationship between unequal parties. For instance, in chemical pollution cases, if the plaintiff establishes that the defendant discharged hazardous waste, the court shifts the onus to the factory to prove its emissions did not cause the injury. This statutory device prevents large corporations from exploiting their access to technical data.
Procedural Consequence
Once the court applies this rule, the defendant must produce affirmative evidence of compliance or non-infringement to avoid an immediate adverse judgment. Legal counsel must present detailed records, independent laboratory results, or technical audits to satisfy the new evidentiary requirement. This shift changes the strategic landscape of the trial, forcing the defending party to expose its internal operations and proprietary technical records to the court.
If the defendant cannot produce sufficient documentation to meet this standard, the judicial panel will rule in favor of the plaintiff without further demonstration of liability.
Evidentiary Allocation
Allocation of this duty remains a question of law determined by the presiding judges before the presentation of testimony. Although this doctrine is powerful, it is restricted to specific cases defined by national civil statutes. It cannot be applied arbitrarily to bypass the plaintiff’s fundamental duty to initiate a claim.
