2차적 저작물작성권의 양도추정에 관한 연구

There is no question that the creator of a derivative work that is not an infringement of the underlying work is the owner of rights of copyright in that derivative work, but does not acquire any rights to the underlying work. The creator of a derivative work must create the derivative work with the authority of the copyright proprietor since the copyright proprietor of the underlying work has the exclusive right to make derivative works.

Recently, there has been critic on the presumption of assignment the right of the production and exploitation of a derivative software work. This study examine the legal problems of Section 45(2) of the KCA.
