This paper develops a model for understanding a firm¡¯s decisions regarding the maintenance (renewal) and patenting of sequential innovations and studies how these decisions are affected by the model¡¯s parameters such as maintenance fees and filing fees. The model offers a discriminating testable hypothesis, predicated on the cross-price effects, to identify complementarityor substitutability across sequential innovations. Our empirical results show that higher filingfees are associated with lower probability of patent renewal, which corroborates the case of complementarity in sequential innovations.
