Considering international conflicts in the intellectual Property area which have been growing more intensive on the day-by-day basis, This thesis has intended to propose ways as to how we improve our patent trial system structurally so that it helps to strengthen the national competence and seek the more proper protection for intellectual properties.And I have taken a brief look at the legal characteristic as well as the current situation and the significance of the patent trial system(PTS). Besides, I have reviewed the relationship between the PTS and the patent suit system by comparing the examination principles and varieties of the patent trial procedure to those of civil suit procedure such that I have tried to figure out what the problem is in the PTS and offer new proposals to improve it.By reviewing PTS not only in the major countries but japan which is currently emerging as a big market and benchmarking the upsides which they might have, I have tried to find out more efficient and less time-consuming ways to settle the disputes in trial and suit arena involving patent.Overall in Chapter Ⅲ and Ⅳ, I have taken a step to find out many problems awaiting solution in structures and operations which the present PTS might have in a across-the-board way, which has been based on digging out new proposals applicable to solving the present problems. Particularly, L focused on the issues over jurisdiction, the patent attorney in the court and cooperation between the court and the intellectual property tribunal that the duality of judicial process is supposed to raise with regard to intellectual property related dispute.
