Description: The earliest definition of a patent thicket that we found is in Teece (1998), who points out a simple issue with patents. We refer to this as ‘saturated invention spaces’ and describe it as when a single firm, or a small number of firms, successfully patents an entire technological area. (p.15) Market Failure: Imperfect competition: a small number of firms hold all possible patent rights in an area Look for: Terms like “cluster”, “related”, “adjacent”, or “coherent group” to describe either patents or inventions. However, we also included several definitions that described patents as “minor” or “marginal” provided that there was no suggestion of bad faith
B) '''Diversely-held Complimentary Inputs (DHCI):''' 1) products require complementary patented inputs; 2) these inputs are diversely-held (i.e. held by N patent-holders); and 3) patent-holders set their license prices independently. (Shapiro, pg.17)
