This document summarizes a presentation on open innovation challenges and directions. It discusses the history and theory of open innovation, noting it recognizes not all ideas can be developed internally. Elements of the open innovation model include the proportion of in-house vs external R&D and proprietary vs non-proprietary IP strategies. Digital convergence and platforms have implications for open innovation, requiring engagement with external ideas, technologies, and assets. Business model options are more varied in multi-invention contexts. Aligning complementary assets and partners is key, as emphasized by Adner's "wider lens" approach. Sensing external opportunities and seizing them through collaboration are ongoing challenges for open innovation.
