abstract={Patent race models assume that an innovator wins the only patent covering a product. But when technologies are complex, this property right is defective: ownership of a product’s technology is shared, not exclusive. In that case I show that if patent standards are low, firms build “thickets” of patents, especially incumbent firms in mature industries. When they assert these patents, innovators are forced to share rents under cross-licenses, making R&D incentives sub-optimal. On the other hand, when lead time advantages are significant and patent standards are high, firms pursue strategies of "mutual non-aggression." Then R&D incentives are stronger, even optimal.},

thicket_def_extract={The problem Baker describes is often called a "patent thicket." These occur when each product may involve many patents, in contrast with the one-to-one correspondence between products and patents that is assumed in the patent race literature. Recent commentators suggest that lower patenting standards encourage patent thickets, creating difficulties for innovators (see Gallini, 2002, for a review). When innovators must negotiate with large numbers of patentholders, they may face excessive transaction costs (Heller and Eisenberg, 1998), "holdup," and problems of vertical monopoly (Shapiro, 2001).},
