This article contains an analysis of the relevant intellectual property rights concerning e-health projects using grid computing infrastructure within a clinical trial environment. There are two important issues at stake: which (intellectual) property rights arise during the course of such a project and which patient rights have to be regarded? This article aims to answer these questions. The answers shall contribute to the current discussion in this field.
