In order to overcome the above shortcomings, it is necessary to perfect the three levels, such as the construction of the elective standards and management methods, the legal and public litigation procedures, the relationship between the internal and external coordination and the judicial identification system, so as to give full play to the enthusiasm of the system in identifying the technical facts of the cases, so as to help the intellectual property litigation in the scientific and technological innovation. The judicial guarantee function is effectively played in the field.
