Issues in the subject focus of IP management at the Graduate school of the Diesel Board of Trustees are regularly characterized by complexities and implications that cannot be adequately represented scientifically in individual doctoral projects. The aim of the excellence groups is to work on the subject focus as comprehensively as possible and precisely in their practice-relevant complexity. For this purpose, groups of doctoral students work together under one umbrella topic on the various facets, in order to avoid excessive isolation of the questions and to achieve overarching results from different perspectives through mutual exchange. Professional interaction and pooling of resources enable excellent results in an international comparison and is the basis for progress in knowledge, competence and practical implementation in business.
