Protection of information goods and free use: Constitutional analysis on the preliminary injunction of copyright law

数字化和网络技术的发展，彻底改变了模拟时代人们习以为常的信息交易方式。一方面，我们可以很容易地获取、创建和传播信息。另一方面，数字技术结合技术保护措施和合同，可以控制信息的自由流动。此外，权利人试图延长版权的期限，并根据分担责任原则起诉中间人等，在这方面，版权保护比以前更强。我们正处于两种截然不同的著作权观交汇的时代，本课题从著作权法中的先行禁令的宪法分析的角度，对信息商品的保护和自由使用进行了研究。近年来，著作权保护被公认为宪法框架内的先行限制的“神圣领域”，也有人开始质疑其正当性。本文试图结合法经济学的方法论进行分析，从宪法学的角度，将诽谤罪与隐私权保护进行比较分析。从知识产权的角度来看，我们的研究包括版权限制和例外（美国的合理使用）。S.语境）、技术保护措施对表达自由的寒蝉效应、著作权限制的契约可覆写性等。著作权法是商法的一部分。因此，我们应审慎研究规管架构，尽量从“中性”的角度出发，不影响市场上的商业活动。在什么情况下应当采用非强制性信赖担保制度，是贯穿整个工程的一个非常重要的问题。最后，我们尝试从两个角度进行综合研究。

The development of digitization and network technology has totally changed the scenery of information transactions whet we had taken for granted in the analog era. On the one hand, we can access, create and disseminate information easily. On the other hand, digital technology can control free flow of information combining the technological protection measures and contracts. Also, the right holders tried to extend the duration of copyright and sued intermediaries based upon the doctrine of contributory liabilities, etc. In this regard, copyright protection is getting stronger than before. We are in the era in which two completely different views toward copyright converges.In this project, we made a research of protection of information goods and free use from the perspective of constitutional analysis on the preliminary injunction of copyright law. Recently it is widely acknowledged that copyright protection is the "sacred area" of prior restraint within the framework of constitutional law, and some people begin to wonder whether it is justifiable. We tried to analyze combining the methodology of law and economics.From the constitutional point of view, we tried to make an analysis comparing with defamation and privacy protection. From an intellectual property perspective, our research encompasses the area of copyright limitations and exceptions (fair use in U. S. context), chilling effect of the technological protection measures on freedom of expression, and contractual overridability of copyright limitations, etc.Copyright law is a part of business laws. Therefore, we should carefully examine the regulatory framework not to affect the business activities in the market from the "neutrality" point of view as mush as possible. In what circumstances not injunctive relied bur levy system should be adopted is a very important question throughout the project. At the end, we tried to synthesize the research from the both perspectives.
