Abstract
The most recent literature as well as the practice of companies are bringing into evidence that ensuring appropriability is very difficult, in the context of open innovation. The purpose of this paper is to study this problem, and, in particular, it is analyzed the role of organizational and managerial mechanisms in reinforcing the effectiveness of other IPPMs in collaborative NPD. The paper is based upon literature analysis and a multiple case study, involving three companies, and sheds some light on the specific organizational and managerial interventions that can be introduced within companies in order to improve the effectiveness of the IP strategy in collaborative NPD.
