Abstract
In this paper the objective is to explore the relationship between Intellectual Property and technological collaborations along the innovation process. The study is based upon a literature analysis and a multiple case study involving three Italian companies which adopted an open approach to innovation. As a result, the paper proposes a framework which explains how different IP protection mechanisms, either legal or strategic, can be exploited to protect technology and know-how in collaborations concerning different phases of the innovation funnel. The paper also sheds some light on the role of IP protection mechanisms as enablers / facilitators / limiting factors for companies who want to open their innovation process to external partners.
