This paper explores the decentralized licensing of complementary patents reading on a technology standard. We develop a model in which manufacturers must buy licenses from different patent owners in order to enter the market for differentiated standard-compliant products. We consider three different types of licensing, namely, the fixed-fee, per-unit royalty and two-part tariff regimes, and compare their performances in terms of licensing revenue, price, product variety and welfare. We show that each regime entails different types of coordination failures. We establish that each of them may maximize the licensing revenue depending on the number of licensors, number of potential entrants and product differentiation.
