Shared copyright of a software application

The case concerned ‘Mr X’, ‘Mr Y’ and an application called eKidz. The idea, functionality and interface design of the application originated from X, who had hired Y to develop the actual application. They worked together, with X leading the project and setting the course. This ended when a dispute between the parties arose. As the creator of the idea, the functionalities and the interface of the application, X claimed to be the owner of all copyright material related to the application, which Y disputed.
