Corporate open innovation – why bother?

is the subtext of my article.  I think there are lots of excuses (so-called "barriers") for not considering corporate open innovation.  The usual suspects are intellectual property, complexity and an unwelcome interdependence of companies. More interestingly I think there’s a sort of glass ceiling formed by more human issues such as intertia, corporate culture/tradition and psychological factors.  So I choose not to believe in barriers to open innovation but in accelerators such as personal and cultural change and thinking outside the company box.  Does any of this chime with you?
