Abstract: Patent pool is always the focus of review by anti-trust regulators. This paper constructs a composition model composed of the binary choice model and the lagged variable model, selects some data related to 24 anti-monopoly cases of patent pool of the United States, European Union and Japan and to China's macroeconomic development, and makes an empirical research on the macroscopic factors of anti-monopoly for foreign patent pool. The result shows that whether the antitrust law system is mature, its impact direction is uncertain, the economic growth rate has a significant negative effect, the unemployment rate, trade deficit and import penetration rate has significant positive effects, and then it further selects the case in which Chinese enterprises prosecute DVD 3C patent pool in the United States in 2004 to analyze as a case study. On this basis, some conclusions and enlightenments are obtained from this paper.

Key words: patent pool, antitrust policy, macroscopic factors
