Technical expert assigned to a court in China provides the judge with professional insight into complex engineering or scientific matters during an intellectual property trial. This role, known as jishu diaochaguan, was created to address the difficulty that many judges face when dealing with highly technical cases involving patents, software or integrated circuits. Unlike an expert witness who is hired by one of the parties, the technical investigation officer is a neutral official who works directly for the court.
They assist the judge in understanding the technical evidence, participate in hearings, and provide a written opinion on the scientific aspects of the case. While they do not have the power to make a final legal decision, their findings carry heavy weight and often determine the outcome of a technical dispute. This system ensures that the court’s judgment is based on a sound understanding of the technology involved.
Execution of the duties of a jishu diaochaguan begins with the review of the case materials to identify the core technical issues. During the trial, the officer may ask questions of the parties and their expert witnesses to clarify specific points of engineering or logic. They are often involved in the evidence preservation process, where they ensure that the technical data is captured correctly and that the chain of custody is maintained.
After the hearing, the officer prepares a report for the judge that explains the technical principles in a way that is easy to understand. This report might compare the claimant’s patent with the defendant’s product or analyze the results of a source code review. The officer must remain objective and avoid taking a side in the dispute.
Their role is strictly to provide the court with the information it needs to apply the law correctly. This internal expertise allows the court to handle complex cases more efficiently and reduces the reliance on external appraisal institutions.
Integration of these experts into the judicial process is governed by specific regulations issued by the Supreme People’s Court. The jishu diaochaguan is present in most specialized IP courts and is increasingly used in general courts that handle a high volume of technology cases. When a judge decides that a case requires technical expertise, they will assign an officer with the appropriate background in the relevant field.
The officer attends the court sessions and may participate in pre trial meetings to help narrow the scope of the dispute. They can also assist the judge in drafting the parts of the judgment that deal with technical descriptions and comparisons. If a party disagrees with the officer’s findings, they can provide their own evidence or ask for an independent appraisal.
However, the officer’s position as a court official gives their opinion a level of credibility that is hard to overcome. This system has been successful in improving the quality and consistency of intellectual property judgments in China.
Management of the intellectual property system has been improved by the presence of these technical officers, as they help to bridge the gap between law and technology. Their involvement ensures that the court is not misled by biased expert testimony or by a lack of understanding of the scientific facts. For foreign companies, the presence of a jishu diaochaguan provides some assurance that their technical arguments will be understood and evaluated fairly.
It also speeds up the trial process by allowing the court to address technical questions directly rather than waiting for external reports. The system is part of a broader effort to professionalize the judiciary and make it more capable of handling the challenges of a modern economy. As technology continues to evolve, the role of these officers will become even more important.
They provide the necessary expertise to protect innovation and ensure that the law is applied accurately in a digital world. The presence of such specialists is a hallmark of the specialized IP courts in China.
Litigation success in Chinese IP courts requires securing notarized pre-trial evidence to trigger statutory burden shifting and judicial document production.
