Disintegrated or distributed innovation, collaborative innovation, collective invention, collegial innovation, free innovation, open knowledge disclosure, free knowledge disclosure: are these all the same thing? This shows us there is some confusion regarding open innovation, or at least there is a need to cast a wider net around what open innovation is all about. The prevailing thought is that open innovation allows organizations to simultaneously expand their breadth of ideas, opportunities, and know-how while minimizing the technical and market risks associated with innovation. As a result, open innovation appears to come with little down side. Del Giudice, Della Peruta, and Carayannis fill the gap in our understanding of this emerging research field of open innovation. Their work depicts the major tendencies of publications through identifying the main themes in literature and investigating the research frontier. It also discusses potentially important fields of investigation that are still left rather unexplored.
