In a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead buy or license processes or inventions (i.e. patents) from other companies. In addition, internal inventions not being used in a firm’s business should be taken outside the company.
Henry ChesbroughNo one has a monopoly on knowledge the way that, say, IBM had in the 1960s in computing, or that Bell Labs had through the 1970s in communications. When useful knowledge exists in companies of all sizes and also in universities, non-profits and individual minds, it makes sense to orient your innovation efforts to accessing, building upon and integrating that external knowledge into useful products and services.
