This article attempts to describe how the ROC copyright legal system is similar to other WTO members through looking at the retrospect of its copyright system. The ROC copyright system adopts the principle of creative protection, which means the copyright of a work and the rights of the creator are automatically protected when the work is completed. Unless the creator of the work renounces his own rights or agrees to share the copyright, his rights are protected by the Copyright Act and are guaranteed civil and criminal prosecution rights. Generally speaking, when a third party wishes to use a copyrighted work, he must obtain authorization or consent from the copyright holder(Artic1e 37.1). In practice, however, reaching an authorization agreement and implementing such agreement are not easy tasks, since these involve certain trading costs, namely, search costs, negotiation costs, and implementation costs. In other words, the more complicated the authorization is, the higher the cost will be. Since the ROC Copyright Act does not require the copyright holder to display his name or contact information (although there is an Electronic Rights Management Information mechanism in place, it provides the right holder with management rights and is not compulsory), in many cases, the users do not know who the copyrighted work belongs to or cannot contact the right holder since no contacts are provided. As a resu1t, authorization agreement cannot be reached. This article analyzes the dilemma of the above copyright authorization and use, and emphasizes the difficulty of obtaining authorization for work posted on the Internet, since in a knowledge-based economy era, the use of work on the Internet can easily result in copyright infringements. This article then continues to introduce the discontentment that some liberal scholars have expressed toward copyright laws the world over being overly protecting of right holders. Among them, is Professor Lawrence Lessig of Stanford University, who proposed the concept of Creative Commons(CC), whereas the creator voluntarily shares his copyrighted work with non-specified users by marking the work with simple symbols to indicate whether the work can be shared in whole or in parts. This mechanism has shed some light on the problem of authorization. Since its campaign began in 2003, CC has already received support from over thirty countries. In the ROC, the Academia Sinica’s Institute of Information Science and Institute of Law (Preparatory Office) took the lead in echoing such campaign. Currently, the 2.0 Chinese version of the CC license has been completed. The Taiwan Intellectual Property Office is also providing assistance to the Academic Sinica to promote such campaign, so that a sound environment for knowledge sharing can be created for the creators and users. In closing, this article looks at how the CC licensing mechanism can be incorporated into the existing authorization system of the Copyright Act, and also how it can harmonize with the newly added Electronic Rights Management Information of 2003 and the Technical Protection Measures of 2004. In addition, while the ROC is in its initial stage of promoting CC, this article proposes to incorporate an Internet confidential mechanism or the use of an electronic signature mechanism to ensure sustainable development of Creative Commons in the ROC. This method will help the CC campaign take roots in the ROC and facilitate the early completion of a free information-sharing platform.
