Abstract
Although it is sometimes in conflict with the aims of the profit seeking enterprises, antitrust law is enforced on the basis to prevent restraints on free trade and commerce. This paper focuses on the issue of price fixing and volume allocation of a certain case among major corporations, as well as technology development collaboration among competitors. Cases are analysed and a specific proposal is made as to what maybe an effective approach and what should be considered in minimizing violation where a number of market influencing enterprises cooperate in sales, and in research and development. Recent signing of a treaty regarding cooperation between the US and Japan on antitrust cooperation will undoubtedly accelerate globalized enforcement to have influence on expanding globalization in marketing.
