Abstract:Intellectual property rights are exclusive. That means, in intellectual property law, there is a contradiction between the proprietary of intellectual property products and the public legitimate need for intellectual property products. In recent years, the reasonableness of intellectual property law was being questioned and criticized a lot. Actually, the movements, which are represented by open source movement and oppose intellectual property rights, bring reflection for intellectual property system. It promotes the properly use of intellectual property products which have both public and private attributes. In this way, intellectual property law can achieve the goal of fair and justice.
