It is also an objective to study the influence of the coexistence of independent innovations and the cumulative nature of innovation in such conditions. Three models have been proposed: the first one textcite{takalo2001} represents a scenario with an isolated innovation, the second one features two independent innovations, and the third model features two linked innovations, one of which is a ``research tool'' for the development and the introduction of the other one. Sufficient conditions for the optimality of patents with maximum breadth or infinite length were presented.
