Fig. (1) Mapping the options for drug innovation structures according to the degree of market engagement to provide incentive to bring the product through the development pipeline and the degree to which exclusivity or leverage is exercised over the core technologies. This Figure is potentially useful only as an illustration of the range of possibilities and practical design issues in shaping a strategy and is not a precise analytical tool; actual choices vary more considerably – for example, some public private partnerships entail complete nonexclusivity.
