Patent litigation is the combination of law, technology and management, which differs from the conventional types of litigation. In the knowledge-based economy era, patent litigation has grown dramatically in importance. Faced with the trend of globalization in patent dispute resolution, reform of Taiwanese patent litigation mechanism has been definitely necessary. Among the whole mechanism, correct observation on patent litigation and model of case management, are the most important parts urgently in need. Thus we can not only further concrete the procedural right protected by the constitution, but also pave the path destined to developing the knowledge-based economy. We shall take the following observation of patent litigation seriously upon the basis of invisible property: close relation to business, globalization, protecting procedural rights from pretrial stage, foundation of promoting business competitiveness, to further improve patent litigation. For the purpose of reforming the pretrial procedure of Taiwanese patent litigation, we should first focus on the establishing an ideal model of case management, including claim construction process featuring on debates and examination between the litigants. The court should especially endeavor on scheduling the litigation procedure through pretrial conference, and seek resolution through mid-trial. According to the present laws and regulation, carrying out the above suggestion might not be impossible, however, legislative improvement should be a more radical way for the status-quo. After Korea and Japan, Taiwan is now establishing the Intellectual Property Court. In the opinion of this thesis, we should make fundamental reformation on the litigation process to meet the need of globalization. As for the principles for future litigation mechanism, we must settle patent infringement disputes with unilateral litigation procedure, decrease or eliminate active investigation from the court on the disputed issue, and change the doctrine of objective burden of proof. The foregoing suggestions can be taken into consideration during the legislation of the Intellectual Property Court as to provide solid reconstruction of patent litigation in Taiwan.
