在许可贸易中,许可人对被许可人可能规定各种限制性条件以继续维持对技术的优势地位或者获取垄断地位。在这些限制性许可条件中,由于存在着滥用知识产权的可能而必须接受反垄断法的审查。问题的关键是,法律形式意义上的审查不足以解释限制性许可的经济效果,相反,以经济分析为基础的合理性审查可以对限制性专利许可行为的合法性提供依据。 In licensing trade, the licensor may impose various restrictive conditions on the licensee to continue to maintain its technological superiority or monopoly position. Under these restrictive licensing conditions, antitrust laws must be subject to review because of the potential for abuse of intellectual property. The crux of the matter is that censorship in the legal form is not sufficient to explain the economic effect of restrictive licenses. Rather, a reasonable review based on economic analysis can provide a basis for the legality of restrictive patent licensing practices.
