Promoting Access to Intellectual Property: Patent Pools, Copyright Collectives and Clearinghouses

This paper reviews and compares patent pools, intellectual property clearinghouses and copyright collectives as systems for promoting efficient access to licensable intellectual property in a 'market for technology' (Arora et al, 2001). These systems promote downstream use of innovations by economizing on search and transaction costs in licensing, as well as potentially mitigating the conditions that lead to the 'tragedy of the anti-commons' and other coordination problems in multilateral licensing. We compare and classify different systems in terms of their features, review some existing systems, and discuss their economic characteristics.Intellectual property, licensing, markets for technology, collective rights management, patent pools, clearinghouses
